Favorite Excuse For Not Doing Yoga: I'm NOT Flexible

FitSugar — Tue, 25 Sep 2007 08:45:00 -0700

When people find out that I teach Pilates and yoga, they often immediately disclose the reasons they don't practice either exercise form. I hear this excuse most often, "I could never do yoga, I'm so inflexible. I can't even touch my toes."

This is not the first time I've heard this excuse, and I actually love that people confess this to me. It gives me a chance to explain that inflexibility is not an excuse, but rather a reason to do yoga.

Most people aren't naturally flexible, but doing yoga can increase your flexibility almost immediately. Even after just a few classes, you will begin to notice a change in your body. You just have to get over that mental block that tells you you can't do it, and you just have to try.

If you can commit to a couple of classes every week, I guarantee that your muscles will become longer and suppler. That's what is so great about yoga. Our bodies were made to move, and your muscles crave it. Not only does yoga relax your mind and reduce stress, but the increased flexibility you'll feel can alleviate chronic pain and prevent injury.

So go ahead and take a yoga class. It's like with any new thing you try, whether it be playing an instrument or running a marathon. That amazing sense of pride and accomplishment you feel can only come when you witness yourself improving. No one is instantly great in the beginning, but as you practice, you'll get better and better.

Pros and Cons of the Elliptical

FitSugar — Thu, 15 Oct 2009 05:50:09 -0700

Since running is one of my favorite forms of cardio, I'm a big fan of the treadmill when I can't get outside for a run. I'm also big into the elliptical, and by the looks of my gym, it appears tons of other people are too. While it's a popular piece of gym equipment for so many reasons, there are also some disadvantages to using one. Check out the chart below to see if an elliptical is the right machine for you.

Pros	Cons
The circular motion and the fact that you're not pounding your feet down with each step is easier on your knees than running outside on concrete or on a treadmill. The platforms for your feet are always free of rocks, trash, dog poo, and ice, so you can count on where you're stepping to be safe and clean.	Although using an elliptical is less impact on your joints, it also requires less effort, so people complain that it's too easy. Since your feet need to stay on those little platforms, you feel like you have less control over your movements, and it's less natural for someone who's used to running.

To see the rest of the pros and cons, read more.

Pros

Cons

You control the pace by moving your legs slower or faster.
By increasing the resistance of the foot pedals you can make your workout more challenging for your legs and booty. You can also pedal backward to focus on working your backside.
You can also get an arm and upper back workout by adjusting the tension of the handles.
Since you're inside, you can watch TV to beat boredom.
The readout keeps track of your workout data including time, speed, distance, and calories burned, so you can monitor your progress.
Whether it's a torrential downpour outside or it's nighttime, you can always get in your workout.
It's a safe way to burn calories if you're afraid to exercise outside in your neighborhood.

Since you're in control of how fast your legs are moving, it's easier to slack off as compared to using a treadmill, which keeps the same pace.
Since they're a one-size-fits-all kind of machine, someone who's got a naturally shorter stride may end up hyper-extending their knees, which could lead to injury.
If you don't belong to a gym, ellipticals aren't cheap and you'll end up spending around $2,000 for a good one.
Just like any other piece of cardio equipment, the repetition of doing the same thing over again can be so boring that you cut your workout short.
The readout on the machine may not be accurate.
Ellipticals require electricity, so they're not exactly the greenest type of exercise. Plus, if there's a power outage, you can't work out.

New iPod Nano Has Built-In Pedometer

FitSugar — Wed, 09 Sep 2009 14:30:40 -0700

The iPod Nano makes it easy to pump up your workouts with music, and now a new version just came out that wants to encourage you to move even more. It has a built-in pedometer! Pretty sweet, huh? As you walk or jog, it counts your steps and tells you how many calories you've burned. Talk about motivation. You'll want to park at the far end of the parking lot just to increase the number of your daily steps. The screen is slightly larger than the older version (2.2 inches), making it easier to see and scroll through your music playlists when on the move. There's also a microphone, so you can record a grocery or to-do list while sweating it out.

Not only that, this new Nano also has an FM radio, so if you prefer listening to your favorite station while exercising, you can. I love that it has a built-in video camera too, so if you see a snake while trail running, you can prove it to your pals. It comes in nine bright colors to suit your taste and it's pretty reasonably priced - 8GB for $149 and 16GB for $179.

If you must have this new iPod Nano, you're in luck. It's available in stores now or you can order one online. I want one, do you?

5 Reasons to Bike

FitSugar — Wed, 22 Apr 2009 12:00:00 -0700

Biking is my favorite form of locomotion. The world moves by at the perfect pace when pedaling. You can take in the view and still feel the wind in your face. Riding a bike is a great green way to get around since you can travel a greater distance in a shorter time when compared to walking, and it can be faster than driving. depending on gridlock traffic.

Here are five reasons to bike to work, bike about town, and bike for errands:

Eco: Since it is Earth Day, let's start with the greenest reason - biking reduces your carbon footprint. Using pedal power, rather than fossil fuels, for short trips and commutes can reduce your carbon emissions by an estimated 11 percent.
Cardio: Cycling is a wonderful, joint-friendly form of exercise. Instead of burning oil, you burn calories on your bike.
Strength: Biking about town builds leg strength. Pedaling tones your quads and hamstrings as well as your calves. Mini skirts and leggings are fashion trends with staying power, and shorts of all lengths will be very popular this Spring and Summer. Tone your gams while maximizing your pedal power.

See two other reasons to hop on your bike when you read more.

Money: Commute Solutions, out of Austin, TX, has estimated that biking rather than driving can save you serious dough. Pedaling a 10-mile round-trip commute can save you up to $10 a trip when you factor in all your driving expenses.
Fun: Biking is just plain fun. Whether you're speeding down an asphalt hill, navigating your mountain bike over tree roots, or cruising the flats - cycling is a good time.

Why do you bike?

Osteoarthritis

FitSugar — Wed, 08 Oct 2008 17:34:55 -0700

HEALTH GUIDE REFERENCE FROM A.D.A.M

Osteoarthritis (OA) is the most common form of arthritis. It is a joint disease caused by the breakdown of cartilage -- the firm, rubbery tissue that cushions bones at joints.

Healthy cartilage allows bones to glide over one another, and cartilage absorbs energy from the shock of physical movement. In OA cartilage breaks down and wears away. As a result, the bones rub together causing pain, swelling, and stiffness.

OA may also limit the range of motion in affected joints. Most often, OA develops in the hands, knees, hips, and spine.

The disease affects men and women nearly equally. More than 20 million people in the United States have OA. Symptoms tend to appear when individuals are in their 50s and 60s.

Signs and Symptoms

Signs and symptoms of OA may include the following:

Joint pain (often a deep, aching pain) that is worsened by movement and improved with rest (in severe cases, a person may experience constant pain)
Stiffness in the morning or after being inactive for more than 15 minutes
Joint swelling
Joints that are warm to the touch
Crunching or crackling noise when the joint moves (crepitation)
Limited range of motion
Muscle weakness
Abnormal growth of bony knobs near joints which cause deformities (such as Heberden's nodes, in which bumps appear on the outermost finger joints)

Causes

Most of the time, the cause of OA is unknown. It is primarily a disease due to aging. However, metabolic, genetic, chemical, and mechanical factors can play a role in its development.

Risk Factors

Risk factors for OA include:

Increasing age
Genetic predisposition
Obesity
Injury to the joint
History of inflammatory joint disease
Metabolic or hormonal disorders (such as hemochromatosis and acromegaly)
Bone and joint disorders present at birth
Repetitive stressful joint use (such as with occupations like baseball, ballet dancing, and construction work)
Deposits of uric acid crystals in joints

Diagnosis

There is no single test to diagnose OA, so most doctors use a combination of methods to diagnose the disease and rule out the possibility other causes. A physical exam can show limited range of motion, grating of a joint with motion, joint swelling, and tenderness. An x-ray of affected joints will show loss of the joint space and, in advanced cases, wearing down of the ends of the bone and bone spurs.

Preventive Care

The following measures may reduce the risk of developing OA:

Protecting an injured joint from further damage
Exercising
Losing weight
Avoiding excessive repetitive motions

Treatment

The goals of treatment are to relieve pain, maintain or improve joint mobility, increase the strength of the joints, and minimize the disabling affects of the disease. The specific treatment depends upon the affected joints. A combination of conventional treatment and complementary and alternative medicine (CAM) may be most effective. Lifestyle approaches, including exercise, and many alternative medical therapies are becoming more popular and are considered safe and effective for the treatment OA.

Several natural remedies are at least as effective as conventional medication for symptom relief, and may help keep the disease from getting worse. Americans spend more on natural remedies for OA than for any other medical condition. Some of the most promising complementary approaches for treating OA include:

Reducing physical stress on the joint (lose weight and improve posture)
Lifestyle changes (particularly exercise)
Supplements including S-adenosylmethionine (SAMe), glucosamine and chondroitin, and antioxidants
Herbs with anti-inflammatory properties, including boswellia, devil's claw, ginger, turmeric, white willow bark, and capsaicin (cream)
Acupuncture, including TENS or transcutaneous electrical nerve stimulation
Chiropractic
Physical therapy and magnet therapy
Yoga
Tai chi

Exercise

Exercise to strengthen, stretch, and relax muscles around affected joints is almost always included in a treatment plan for OA. Several clinical studies support the value of exercise for people with OA. Clinical studies also suggest that in addition to reduction of pain and disability, exercise improves strength, range of motion, balance and coordination, endurance, and posture.

Medications

The most common type of medication used to treat osteoarthritis are nonsteroidal, anti-inflammatory drugs (NSAIDs). They are common pain relievers that reduce pain and swelling. Types include aspirin, ibuprofen (Motrin, Advil, Nuprin), and naproxen (Aleve, Naprosyn, Anaprox). Although NSAIDs work well, long-term use can cause stomach problems, such as ulcers and bleeding. In April 2005, the U.S. Food and Drug Administration (FDA) asked drug manufacturers of NSAIDs to include a warning label on their product that alerts users of an increased risk for stomach bleeding.

Other medications used to treat OA include:

COX-2 inhibitors (coxibs) -- Coxibs block an inflammation-promoting enzyme called COX-2. This class of drugs was initially believed to work as well as traditional NSAIDs, but with fewer stomach problems. However, numerous reports of heart attacks and stroke have prompted the FDA to re-evaluate the risks and benefits of the COX-2s. Rofecoxib (Vioxx) and valdecoxib (Bextra) have been withdrawn from the U.S. market following reports of heart attacks in some patients taking the drugs. Celecoxib (Celebrex) is available and labeled with strong warnings and a recommendation that it be prescribed at the lowest possible dose for the shortest duration possible. Patients should ask their doctor whether the drug is appropriate and safe for them.
Corticosteroids -- Also known as steroids, these medications are injected directly into the joint. They may also be used to reduce inflammation and pain. Steroids for inflammation inlclude prednisone (Deltasone) and dexamethasone (Decadron). Steroids, however, may cause side effects, such as weight gain, nausea, and fluid accumulation (edema). Steroids may also cause drug interactions. Ask a pharmacist or doctor.
Artificial joint fluid (Synvisc, Hyalgan) -- These medications can be injected into the knee. They may temporary relief pain for up to 6 months.

Surgery and Other Procedures

Surgery to replace or repair damaged joints may be needed in severe, debilitating cases. Surgical options include:

Arthroplasty (total or partial replacement of the deteriorated joint with an artificial joint)
Arthroscopic surgery to trim torn and damaged cartilage and wash out the joint
Osteotomy (change in the alignment of a bone to relieve stress on the bone or joint)
Arthrodesis (surgical fusion of bones, usually in the spine)

Nutrition and Dietary Supplements

Following these nutritional tips may help reduce symptoms:

Eliminate potential food allergens and foods that increase mucous production, including dairy (milk, eggs, cheese, sour cream, and ice cream), wheat (gluten), soy, corn, potatoes, cabbage, bananas, sugar, preservatives, food additives and excessive salt and meats. Your health care provider may want to test for food sensitivities.
Eat more foods that decrease inflammation, including garlic, onions, watercress, horseradish, mustard, parsley, celery, rose hips tea, pickles, lemon, and anti-inflammatory oils (nuts, seeds, cold-water fish).
Eat more foods containing digestive enzymes, such as papaya and pineapple.
Avoid refined foods, such as white breads, pastas, and sugars.
Eat fewer red meats and more lean meats, cold-water fish, tofu (soy, if no allergy) or beans for protein.
Use healthy cooking oils, such as olive oil or vegetable oil.
Reduce or eliminate trans-fatty acids, found in commercially baked goods such as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
Avoid coffee and other stimulants, alcohol, and tobacco.
Drink 6 - 8 glasses of filtered water daily.
Exercise moderately, for 30 minutes daily, 5 days a week.

You can address nutritional deficiencies with the following supplements:

Glucosamine/chondroitin, 500 - 1,500 mg daily, for joint health.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 tbsp. oil daily, to help decrease inflammation and improve immunity. Higher doses may be used by health care providers.
A multivitamin daily, containing the antioxidant vitamins A, C, D, E, the B-vitamins and trace minerals, such as magnesium, calcium, zinc, and selenium.
Digestive enzymes, 1 - 2 tablets three times daily with meals.
Coenzyme Q10, 100 - 200 mg at bedtime, for antioxidant and immune activity.
N-acetyl cysteine, 200 mg daily, for antioxidant effects.
Acidophilus (Lactobacillus acidophilus), 5-10 billion CFUs (colony forming units) daily, when needed for maintenance of gastrointestinal and immune health. You should refrigerate your acidophilus products.
SAMe (s-adenosyl-L-methionine), 100 - 200 mg before breakfast daily, to help decrease inflammation.

Herbs

Herbs are generally available as standardized, dried extracts (pills, capsules, or tablets), teas, or tinctures/liquid extracts (alcohol extraction, unless otherwise noted). Mix liquid extracts with favorite beverage. Dose for teas is 1-2 heaping teaspoonfuls/cup water steeped for 10 - 15 minutes (roots need longer).

Green tea (Camellia sinensis) standardized extract, 250 - 500 mg daily, for inflammation, and for antioxidant and immune effects. Use caffeine-free products. You may also prepare teas from the leaf of this herb.
Bromelain (Ananus comosus) standardized, 40 mg three times daily, for pain and inflammation.
Turmeric (Curcuma longa) standardardized extract, 300 mg three times a day, for pain and inflammation.
Cat's claw (Uncaria tomentosa) standardized extract, 20 mg three times a day, for inflammation.
Devil's claw (Harpagophytum procumbens) standardized extract, 100 - 200 mg one to two times daily, for inflammation.
Willow bark (Salix alba) standardized extract, 500 mg up to three times daily.

Capsaicin (Capsicum frutescens) Cream

Capsaicin is the main component in hot chili peppers (also known as cayenne). Applied to the surface of the skin, it is believed to deplete stores of a substance that contributes to inflammation and pain in arthritis. Several clinical studies have shown that capsaicin cream provided much better pain relief than a placebo but no improvement in joint swelling, grip strength, or function for people with OA. Pain reduction generally begins 3 - 7 days after applying the capsaicin cream to the skin.

Acupuncture

Several controlled clinical trials suggest that the ancient Chinese practice of acupuncture is an effective treatment for pain associated with OA, as well as for other aspects of the condition, including diminished joint function and reduced walking ability. In fact, a few clinical studies have shown that people with OA experience better pain relief and improvement in function from acupuncture than from NSAIDs such as aspiroxicam.

Chiropractic

Although there is no evidence that chiropractic care can reverse the joint degeneration that causes OA, some clinical studies indicate that spinal manipulation may:

Increase range of motion
Restore normal movement of the spine
Relax the muscles
Improve joint coordination
Reduce pain

A comprehensive review of the scientific literature suggests that chiropractic, especially when combined with glucosamine supplements and rehabilitative stretches and exercise, is an effective supplemental treatment for OA. Chiropractors will avoid using direct thrusts or pressure on red, swollen joints.

Physical Therapy

Physical therapy can be useful to improve muscle strength and the motion at stiff joints. Therapists have many techniques for treating OA.

Manual therapy and supervised exercise may decrease or delay the need for surgery in individuals with OA. In a trial evaluating physical therapy and exercise in people with OA of the knee, participants who received manual therapy to the lumbar spine, hip, ankle, and knees showed the following improvements:

Less stiffness
Reduced pain
Improved functional ability
Improved walking distance
Less need for knee surgery 1 year later

Magnet Therapy

Exposure to electromagnetic fields has boosted the number of cartilage-building cells and substances in laboratory experiments. One important study found that low-energy AC and DC magnetic fields stimulated the production of cartilage. For therapeutic purposes, users can apply magnets in one of two ways: directly to the skin surface over the bone or joint (capacitive coupling) or via pulsed electromagnetic fields (PEMFs) which induce an electrical current in the target tissue without making direct contact to the body (inductive coupling).

Clinical studies using either type of magnet therapy for arthritis are limited, and the few that exist have used poor methods, making it difficult to draw any definite conclusions. However, in one study of 78 people with OA of the knee, magnet therapy (applied to the knee for 6 - 10 hours per day over a period of one month) significantly reduced pain as compared with placebo.

Balneotherapy (Hydrotherapy or spa therapy)

Balneotherapy is one of the oldest forms of therapy for pain relief for people with arthritis. The term "balneo" comes from the Latin word for bath (balneum) and refers to bathing in thermal or mineral waters. Sulfur-containing mud baths, for example, have been shown to relieve symptoms of arthritis. However, hydrotherapy, which can be performed under the guidance of certain physical therapists, is occasionally used interchangeably with the word balneotherapy. The goals of balneotherapy for arthritis include:

Improving range of joint motion
Increasing muscle strength
Eliminating muscle spasm
Enhancing functional mobility
Easing pain

Although balneotherapy is most often used for psoriatic or rheumatoid arthritis, some medical experts believe that it may be beneficial for OA as well. However, one large review of clinical trials found little evidence to support its use.

Ice Massage, Transcutaneous Nerve Stimulation (TENS), and Electroacupuncture

In a well-designed trial comparing the effectiveness of TENS, electroacupuncture, and ice massage for the treatment of knee OA, each of these methods were found to:

Reduce pain at rest
Reduce stiffness
Boost walking speed
Increase quadriceps muscle strength
Increase knee range of motion

TENS is a technique used by many physical therapists. When the nerve stimulation of TENS is applied to acupuncture points, it is called electroacupuncture.

Mechanical Aids

A variety of mechanical devices, called orthoses, are available for people with OA to help support and protect joints. Made from lightweight metal leather, elastic, foam, and plastic, orthoses allow some movement within the affected joint and do not restrict nearby joints. For example, splints or braces help align joints and properly distribute weight. Shock-absorbing soles in shoes can help in daily activities and during exercise. Physical therapists use these mechanical aids most frequently to treat arthritic hands, wrists, knees, ankles, and feet. Orthoses should be custom-fitted by a physical or occupational therapist.

Homeopathy

Although very few studies have examined the effectiveness of specific homeopathic therapies, professional homeopaths may consider the following treatments to alleviate respiratory symptoms (such as those experienced from cystic fibrosis) based on their knowledge and experience. Before prescribing a remedy, homeopaths take into account a person's constitutional type -- your physical, emotional, and psychological makeup. An experienced homeopath assesses all of these factors when determining the most appropriate treatment for each individual.

Although people with OA are best treated with an individualized homeopathic remedy chosen by a professional homeopath, several trials have found that some common homeopathic combinations may be at least as effective as conventional medications for OA. Potential remedies include:

A topical homeopathic gel containing comfrey (Symphytum officinale), poison ivy (Rhus toxicodendron), and marsh-tea (Ledum palustre)
A combination homeopathic preparation containing R. toxicodendron., Arnica montana (arnica), Solanum dulcamara (climbing nightshade), Sanguinarra canadensis (bloodroot), and Sulphur
A liquid homeopathic preparation containing R. toxicodendron, Causticum (potassium hydrate), and Lac vaccinum (cow's milk)

Other Common Homeopathic Remedies for OA Include:

Calcarea carbonica (carbonate of lime or calcium carbonate)
Bryonia (wild hops)
Graphites
Guaiacum

Mind-Body Medicine

Chronic pain and disability can make daily functioning difficult. A holistic approach to care in these clinical circumstances may positively affect both lifestyle and how one feels overall. Many people report that relaxation techniques, such as guided imagery and meditation, are an important part of comprehensive, holistic care, and help to alleviate pain and other symptoms of OA.

Yoga

This ancient Indian practice is well known for its physical, psychological, emotional, and spiritual benefits and is often recommended in the West to relieve musculoskeletal symptoms. In one clinical trial studying OA of the hand, the group practicing yoga showed significant decrease in pain and improved range of motion compared to those participating in non-yoga stretching and strengthening sessions. Certain yoga "asanas" (postures) strengthen the quadriceps and emphasize stretching, both of which benefit people with OA of the knee. People with arthritis should begin asanas slowly and they should be performed only after a warm up. Yoga is best performed under the careful guidance of a reputable instructor.

Tai Chi

This ancient form of classical conditioning practiced in China for centuries has been reported in clinical studies to produce a number of benefits, including the following:

Improved fitness
Increased muscular strength
Enhanced flexibility
Reduced percentage of body fat
Diminished risk of falls in the elderly

In a clinical trial of subjects with OA of the knee or hip (ranging in age from 49 - 81), those who practiced tai chi twice a week for 3 months showed significant improvement compared to those in the control group in the following areas:

Overall sense of quality of life
Diminished feelings of stress/tension
Increased satisfaction with general health
Decreased fatigue
Easier self management of arthritis symptoms

Other Considerations

Pregnancy

Many of the herbs used in treatment for OA have not been tested on pregnant women and some are known to be unsafe for women who are pregnant. For this reason, pregnant women should take substances for pain and other symptoms only under the supervision of their obstetrician.

Prognosis and Complications

Complications of OA include:

Inability to walk due to very advanced hip or knee OA
Gastrointestinal bleeding and decreased kidney function resulting from long-term NSAID use

Many people are able to control OA and prevent the condition from worsening over time. Joint deterioration in OA tends to be slower than that of rheumatoid arthritis, but knee OA is still the number one cause of disability in industrialized countries such as the United States. Increased fluid in joints and joint enlargement occur later in the course of the disease. In the most advanced stages, OA can cause full cartilage loss. In some cases joint replacement may become necessary. While OA can be a debilitating condition, current treatments have shown great promise in reducing pain and improving mobility.

You Asked: Training For Big Hikes?

FitSugar — Wed, 04 Mar 2009 05:30:17 -0800

Dear Fit,
This past weekend I hiked Camelback Mountain in Phoenix, AZ. It was fun, but it totally exhausted me. Basically, my entire body is very sore. I can't walk correctly because my right quad is so intensely sore! I work out regularly at the gym, so I'm really disappointed that I'm this sore. Are there any exercises that can help prepare me to hike Camelback again? There is a lot of climbing up rocks on the trail. I would say going back down the mountain is even more difficult. I was really slow for several reasons: bad knees, legs were fatigued, and I was scared of falling. Any suggestions?
-urban chic 101

Hiking is one of the best forms of exercise, and because of that, it's one of my favorite activities. There are definitely some things you can do to prepare for your next trek up Camelback. To find out what, read more.

Start off with some shorter, easier hikes. Even though you work out regularly and are a fit person, a steep hike is really demanding on your body. As your body becomes stronger, gradually increase the difficulty and length of your hikes.
Hike regularly. Just as running gets easier with practice, so does hiking. Get out at least once a week if you can.
Become one with the incline on the treadmill. Adjust the level so it's as steep as possible and work on walking up the hill. Then lower the incline back down, raise the back of your treadmill with wooden blocks, and work on walking downhill. Or just find a steep hill and walk up and down that instead.
When working out, focus on quad strengthening exercises such as lunges and squats. Practice going up and down stairs as well, or use a StairMaster.
When you do go hiking next, carry as little as possible and use a lumbar pack instead of a backpack. It will keep your center of gravity on your hips, so you'll feel more stable on rocky terrain.
Use a pair of trekking poles to help make the ascent and descent easier on your knees.
After a hike, be sure to stretch those muscles to prevent soreness the next day.

Learn to Love the Cable Pulley Machine

FitSugar — Fri, 13 Feb 2009 07:54:42 -0800

There is a lot of love in the air with tomorrow being Valentine's Day, but I want to send a little love to the cable pulley machine. I know that with its sheer size and endless options, it can be a little intimidating. The fact that you can work out almost every part of your body and in any range of motion are good reasons to love it. It is one flexible machine.

New research backs up what many of us feel intuitively after working out with this machine; free-form strength training makes you stronger and more flexible. Not only that, but using the cable pulley machine challenges your sense of balance and improves it considerably more than working with fixed weight machines. In other words, it will help strengthen your core. Another noted benefit: there was a marked decrease in joint pain when working with cable pulley machines. With all these bonuses, how can you walk past this machine?

Remember, celeb trainer Gunnar Peterson said his favorite core exercise was the wood chopper. It is a great exercise to do with the cable pulley, and to see how read more.

Pull the rope down and across your torso by bending and twisting at your waist so that the handle ends up on the far side of your left calf.

Pause at the bottom, then slowly straighten to return to the starting position. Finish the repetitions on that side, then repeat with your left side toward the weight stack.

After attaching a stirrup handle to a high cable pulley, grab it with both hands. With your feet shoulder width apart, stand with your right shoulder toward the cable pulley and hold the rope over your right shoulder. You should feel like you're about to swing an axe.
Exhale, engage your abs, and keeping your back straight, pull the rope by twisting and bending at your waist to bring the handle down and across your torso. The end of the motion is the outside of your left calf. Your right heel should lift as you do this motion. Don't pull with your arms; pull with your torso.
Pause at the bottom, then slowly untwist returning to the starting position. Do 10 reps then switch sides so your left shoulder is closest to the machine.

Do you use this machine regularly? Tell me your favorite exercise using the the cable pulley machine in the comments section below.

Drug Approval

In 2007, the Food and Drug Administration (FDA) approved the atypical antipsychotic drug aripiprazole (Abilify) for treatment of major depression in adults. Aripiprazole is used for treatment of schizophrenia and bipolar disorder. For depression, it is used in combination with antidepressant drug therapy. Researchers are also investigating other atypical antipsychotics for major depression treatment.

Antidepressants and Suicide Risk

In 2007, the FDA proposed adding new information to antidepressant warning labels concerning the increased risk for suicidal thinking and behavior among young adults ages 18 - 24 during the initial months of drug therapy.
The benefits of antidepressants for children and adolescents outweigh their potential risks, suggests a 2007 study in the Journal of the American Medical Association.

Antidepressants During Pregnancy

Most selective serotonin reuptake inhibitors (SSRIs) do not significantly increase the risk for birth defects when taken during early pregnancy, indicate several 2007 studies in the New England Journal of Medicine. However, some SSRIs -- such as paroxetine (Paxil) -- carry a higher risk than others. Researchers are still studying the overall safety of SSRIs during pregnancy. Women with depression should discuss with their doctors all potential risks and benefits.

Introduction

Everyone experiences some unhappiness, often as a result of a change, either in the form of a setback or a loss, or simply, as Freud said, "everyday misery." The painful feelings that accompany these events are usually appropriate, necessary, and transitory, and can even present an opportunity for personal growth. However, when depression persists and impairs daily life, it may be an indication of a depressive disorder. Severity, duration, and the presence of other symptoms are the factors that distinguish normal sadness from a depressive disorder.

Depression has been alluded to by a variety of names in both medical and popular literature for thousands of years. Early English texts refer to "melancholia," which was for centuries the generic term for all emotional disorders.

Depression is now referred to as a mood disorder, and the primary subtypes are major depression, dysthymia (chronic and usually milder depression), and atypical depression. Other important forms of depression are premenstrual dysphoric disorder (PDD or PMDD) and seasonal affective disorder (SAD).

Depression is defined as a mood disorder, and there are several subtypes. Bipolar disorder, also known as manic-depressive illness, is considered in a separate category.

The other major mood disorder is bipolar disorder, or manic-depressive illness, which is characterized by periods of depression alternating with episodes of excessive energy and activity. Bipolar disorder is not discussed in this report. [For more information, see In-Depth Report #66: Bipolar disorder.]

In major, or acute, depression, at least five of the symptoms listed below must occur for a period of at least 2 weeks, and they must represent a change from previous behavior or mood. Depressed mood or loss of interest must be present. Symptoms include:

1. Depressed mood on most days for most of each day -- irritability may be prominent in children and adolescents

2. Total or very noticeable loss of pleasure most of the time

3. Significant increases or decreases in appetite, weight, or both

4. Sleep disorders, either insomnia or excessive sleepiness, nearly every day

5. Feelings of agitation or a sense of intense slowness

6. Loss of energy and a daily sense of tiredness

7. Sense of guilt or worthlessness nearly all the time

8. Inability to concentrate occurring nearly every day

9. Recurrent thoughts of death or suicide

In addition, other criteria must be met:

The symptoms listed above do not follow or accompany manic episodes (such as in bipolar disorder or other disorders).
They impair important normal functions (such as work or personal relationships).
They are not caused by drugs, alcohol, or other substances.
They are not caused by normal grief.

A long-term study found that episodes of major depression usually last about 20 weeks. Between 30 - 40% of depressed patients experience sudden attacks of anger that they describe as uncharacteristic and inappropriate.

Dysthymia, or chronic depression, afflicts 3 - 6% of the general population and is characterized by many of the same symptoms that occur in major depression. Symptoms of dysthymia are less intense and last much longer, at least 2 years. The symptoms of dysthymia have been described as a "veil of sadness" that covers most activities. Possibly because of the duration of the symptoms, patients who suffer from chronic minor depression do not exhibit marked changes in mood or in daily functioning, although they have low energy, a general negativity, and a sense of dissatisfaction and hopelessness.

Double Depression. Often, symptoms become more severe over time. In one long-term study, nearly all patients with dysthymia suffered at least one episode of major depression superimposed over chronic depression (sometimes called double depression) at some time in their life. Some experts believe that such double depression should be considered as part of the natural course of dysthymic disorder. Women may be more susceptible to double depression. In one study, more than one-third of those who recovered from dysthymia relapsed within 5 years.

About a third of patients with depression have atypical depression. Symptoms include overeating and oversleeping. Such patients tend to have a feeling of being weighed down and react strongly to rejection. It tends to occur more in women, unmarried people, and those with other emotional disorders, such as anxiety or substance abuse. It also may impair functioning more severely than ordinary depression does.

Seasonal affective disorder (SAD) is characterized by annual episodes of depression during fall or winter that remit in the spring or summer. Other SAD symptoms include fatigue and a tendency to overeat (particularly carbohydrates) and oversleep in winter. A minority of individuals with SAD has the more common depressive symptoms of undereating and being sleepless. SAD tends to last about 5 months in those who live in the northern part of the U.S.

Seasonal changes affect many people's moods, regardless of gender and whether or not they have SAD. Simply being mildly depressed during the winter does not mean that one has SAD. Living in a northern country with long winter nights does not guarantee a higher risk for depression. Changes in light may not be the only contributor to SAD.

Causes

The causes of depression are not fully known. Most likely a combination of genetic, biologic, and environmental factors are at work.

Because depression runs in families, and has a strong genetic component, compelling evidence suggests that depression is a biologic phenomenon. Data from family, twin, adoption, and genetic studies have confirmed this. Studies have found that first-degree relatives of patients with depression are two to six times more likely to develop the problem than individuals without a family history.

Evidence supports the theory that depression has a biologic basis. The basic biologic causes of depression are strongly linked to abnormalities in the delivery of certain key neurotransmitters (chemical messengers in the brain). These neurotransmitters regulate mood and associated behaviors. Scientists hope that by identifying the gene mutations that code the regulation of these neurotransmitters, they may eventually be able to predict which patients are most likely to respond to specific antidepressant drugs.

Serotonin. Perhaps the most important neurotransmitter in depression is serotonin. Among other functions, it is important for feelings of well-being. Imbalances in the brain’s serotonin levels can trigger depression and other mood disorders.
Other Neurotransmitters. Other neurotransmitters possibly involved in depression include acetylcholine and catecholamines, a group of neurotransmitters that consists of dopamine, norepinephrine, and epinephrine (also called adrenaline). Corticotropin-releasing factor (CRF), which is believed to be a stress hormone and a neurotransmitter, is thought to be involved in depression and anxiety. Increased CRF concentrations appear to interact with serotonin and have been detected in patients with either depression or anxiety.

Endocrine glands release hormones into the bloodstream that are transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary gland to secrete hormones that determine the pace of chemical activity in the body. The more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity.

The degree to which these chemical messengers are disturbed is determined by other factors, such as light, structural abnormalities in the brain, sleep disorders, or genetic susceptibility. For example, researchers have identified a defect in the gene known as SERT, which regulates serotonin and has been linked to depression.

Reproductive Hormones. In women, the female hormones estrogen and progesterone most likely play a role in depression.

Women, regardless of nationality or socioeconomic level, have significantly higher rates of depression than men. The causes of such higher rates appear to be a mix of biologic and cultural factors.

Social and Economic Factors. The role that work, marriage, and children play in a woman's depression is complex. Many women feel that they must be everything to everyone and at the same time feel as if they are no one at all. Such a self-image is common and should be strongly considered as a major contributor to depression in many women, particularly those who work and have small children.

Hormonal Fluctuations and Life Stages. Extreme hormonal shifts can trigger emotional swings in all women. The role of hormones in depression is not clear, however, and is mostly based on observations of depression during specific stages in female development. Female hormones undoubtedly play some role in premenstrual dysphoria, postpartum depression, and SAD. These forms of depression recede or stop after menopause.

Early Puberty. Girls who go through puberty early (reaching the midpoint at 11 years or younger) are more likely to experience depression during adolescence than girls who mature later.

Premenopause. Premenopausal women ages 20 - 45 are most susceptible to depression, with 22% of this age group reporting symptoms of major depression. Specifically, premenstrual dysphoric disorder (severe depression before a period) affects an estimated 3 - 8% of women during their reproductive years. [For more information, see In-Depth Report # 79: Premenstrual syndrome.]

Perimenopause. Depression often occurs around menopause (the perimenopausal period), when, in addition to hormonal changes, other factors such as cultural pressures favoring young women, sudden recognition of aging, and sleeplessness are involved.

Postmenopause. Once women pass into the postmenopausal period, studies suggest that average depression scores are nearly as low as those in premenopausal women. In fact, many women report that after menopause, previous bouts of depression, particularly when caused by seasonal changes or premenopausal syndrome, recede or stop completely.

Premenstrual Dysphoric Disorder. The syndrome of severe depression, irritability, and tension before menstruation is known as premenstrual dysphoric disorder (PDD or PMDD), also called late-luteal dysphoric disorder. It affects an estimated 3 - 8% of women in their reproductive years. A diagnosis of PDD depends on having five or more standard symptoms of major depression that occur during most menstrual cycles, with symptoms worsening a week or so before the menstrual period and resolving afterward. PMDD has features of both anxiety and depression disorders, although experts increasingly believe it is a distinct disorder with specific biochemical abnormalities. [For more information, see In-Depth Report #79: Premenstrual disorder.]

Depression During Pregnancy. Pregnancy is certainly an occasion of great celebration for most women most of the time. However, emotions during that time are not always straightforward, and depression is a common (although most often a temporary) companion. Prenatal depression can affect a mother's sleep, physical activity, adherence to care, and appetite.

Miscarriage. Miscarriage poses a very high risk for depression, particularly in the first month after the loss. Older women with no previous successful pregnancies and those with a history of depression are at particular risk during this time. (Despite some concern that depression increases the risk for miscarriage in the first place, there is no evidence to support this.)

Postpartum Depression. Most new mothers experience weeping, irritability, and confusion for a few days following childbirth. Such symptoms, known as the "baby blues," are not considered signs of postpartum depression unless they persist in severe form nearly every day for more than 1 - 2 weeks.

Women are most likely to develop postpartum depression and other mental disorders in the first 3 months following delivery. (The risk is highest for first-time mothers, especially in the 10 - 19 days after delivery.) Other studies have reported that 8 - 20% of women have diagnosable postpartum depression within that 3-month period. In one study, 5% of these women had suicidal thoughts.

Studies have not found any association between a higher risk for postpartum depression in women and the following:

Educational level
Gender of the child
Whether or not the woman breast-feeds
Whether or not the pregnancy was planned
Whether the delivery was vaginal or cesarean

The rapid decline of reproductive hormones that accompany childbirth is likely to play the major role in postpartum depression in susceptible women. Fluctuating thyroid hormones can also contribute to depression. Studies suggest that women who are more sensitive to hormone fluctuations are at greater risk for postpartum depression if they have one or more of the following conditions:

A history of prior depressive episodes
A family history of mood disorders
Stressful life events (such as being a new mother and having an infant with medical problems)
Lack of social support or feeling as if it is lacking

Depressed children often suffer in silence, and depression may be evident only from reports of problems in school. It is also often difficult for adults to believe that children can be chronically depressed. Symptoms for depression in children often differ from those in adults and may include the following:

An inability to enjoy favorite activities
Persistent sadness
Increased irritability
Complaints of physical problems, such as headaches and stomachaches
Poor performance in school
Persistent boredom
Low energy
Poor concentration
Changes in eating and/or sleeping patterns
A greater tendency to bully others -- anxious children are more often bullied.

Risk Factors for Depression in Children and Adolescents. Depression can occur in children of all ages, including preschoolers, although adolescents have the highest risk (about 20%). Risk factors for depression in young people include having parents, particularly mothers with depression. Early negative experiences and exposure to stress, neglect, or abuse also pose a risk for depression. Sometimes depression develops after a physical illness. In adolescents, feeling alienated from parents is a strong predictor for depression.

Outlook for Future Emotional Problems. Adolescents who have depression are at significantly higher risk for substance abuse, recurring depression, and other emotional problems (such as bipolar disorder) in adulthood.

Risk for Suicide in Adolescents. Suicide is the third most common cause of death among adolescents, and is one of the most devastating events than can happen to a family. Suicide is most commonly associated with depression in young people but it is also linked with anxiety, psychosis, substance abuse, or impulsivity. More girls attempt suicide but more boys succeed, most often because they choose guns or violent methods while girls tend to overdose, which is more treatable. Nevertheless, attempts are major risk factors for a later suicide. Any expression of suicidal intent should be treated very seriously.

The following are danger signs in young people:

Withdrawal from friends
Sudden decrease in school performance
Loss of interest in activities that were previously pleasurable
Unusual irritability
Unusual changes in sleep or eating habits

Risk factors for suicide include a history of neglect or abuse, history of deliberate self-harm, a family member who committed suicide (nearly always one who shared a common mood disorder), access to firearms, and living in communities where there have been recent outbreaks of suicide in young people. A romantic break-up is often the trigger for a suicidal attempt in teenagers. Feeling connected with parents and family protected young people with depression in one study, regardless of gender or ethnicity.

Adolescents may fail to seek help for suicidal thoughts for the following reasons:

They believe nothing would help
They are reluctant to tell anyone they had problems
They think it is a sign of weakness to seek help
They do not know where to go

Parents should not hesitate to seek professional help for their children if they suspect they are thinking about killing themselves. This is a medical emergency and requires immediate treatment.

Behavioral therapies and antidepressants are promising treatments for preventing suicide but need study. There has been a decline in adolescent suicides over the past decade, which some experts attribute to the increased use of antidepressants in this population. However, recent evidence has indicated that antidepressants can also raise the risk for suicidality (suicidal thoughts and behavior) in some people. Children, adolescents, and young adults who are prescribed antidepressant medication should be carefully monitored by both their parents and doctor, especially during the first few months of treatment, for any worsening of depression symptoms or changes in behavior. [See Suicide Risk and Antidepressant Medications in Medication section.]

Although depression in the elderly is very common, the aging process itself is unlikely to be the cause in most cases. An Italian study, for example, indicated that the very old (people who lived beyond 90 years of age) were no more likely to be depressed than younger adults. (The rate was 10% in both groups.) Studies on the cause or extent of depression in the elderly are not clear.

The severity of depression in elderly patients is strongly associated with poor health and less ability to function. In one study of older adults undergoing rehabilitation, half of whom were depressed, as their function improved so did their mood.

Anyone who experiences cumulative negative life events, physical illness, the death of a loved one, impaired functioning, or loss of independence can become deeply depressed. The elderly are at highest risk for such events.

Diagnosing Depression in the Elderly. Because of the complex relationship between depression, drug interactions, and serious physical illness in the elderly, an accurate diagnosis in this group is important but not always straightforward. The characteristic symptoms of depression are not always present or readily apparent in older people:

Some older people may be aware of their depression but believe that nothing can be done about it.
Many elderly people who are depressed may report only physical symptoms (aches and pains) or other mood states (confusion, agitation, anxiety, and irritability) related to depression rather than depression itself.
Often they are unable or unwilling to express their feelings or are even unaware that they are depressed.
Their symptoms are often ignored or confused with other ailments common in the elderly, including Parkinson's or Alzheimer's disease, dementia, thyroid disorders, arthritis, stroke, cancer, heart disease, and other chronic conditions.
Depression is also a side effect of many drugs that are commonly prescribed for the elderly. It is often very difficult, then, to determine if the patient's depression is a psychologic reaction to the illness, caused by the disease itself, or completely independent from the medical condition. Both physical and emotional conditions should be considered in making a diagnosis in older people.

Many studies suggest strong associations between even mild depression and poorer quality of life as well as a shorter lifespan.

Risk for Suicide in the Elderly. Suicide in the elderly is the third-leading cause of death related to injury. Men account for 81% of these suicides, with divorced or widowed men at highest risk.

Effects of Depression on the Ability to Function. Even mild depressive symptoms in people aged 65 and above are associated with a higher risk of becoming disabled and having a lower chance of recovery.

Heart Disease and Heart Attacks. Depression increases the severity of a heart attack and may even impair a patient's response to medication for heart disease. Although people with heart disease may certainly become depressed, this does not explain entirely the link between the two problems. Data suggest that depression itself may be a true risk factor for heart disease as well as its increased severity. A number of studies indicate that depression has biologic effects on the heart, including a higher risk for blood clotting, changes in heart rate, and impaired blood flow to the heart (particularly in response to mental stress). The more severe the depression, the more dangerous to the health, although even mild depression, including feelings of hopelessness, experienced over many years, may harm the heart, even in people with no early signs of heart disease.

Mental Decline. Depression in the elderly is associated with a decline in mental functioning, regardless of the presence of dementia. Depression may be a predictor or even a cause of Alzheimer's disease. Brain scans in the elderly, for example, have reported greater atrophy in the brains of depressed individuals than in those of nondepressed ones.

Risk Factors

According to a major surveys, more than 13% of Americans have major depression disorder over the course of their lifetimes. Furthermore, an estimated 18 million Americans experience major depression each year. Depression is second only to high blood pressure as a chronic condition encountered by primary care doctors. Depression is an illness that can afflict anyone, regardless of age, race, class, or gender. A third of all depressed people consider suicide, and 9% attempt it.

Depression in Women. At any given time, 5 - 9% of women are depressed, compared to 1 - 3% of men. In one study, nearly half of all women surveyed had experienced depression at some point in their lives and over half of those who suffered from it had sought treatment. Women are also more apt to have multiple types of depression (dysthymia and major depression). [For more information, see Depression in Women.]

Depression in Men. Depression is not rare in men. In fact, prepubescent boys are more likely than girls of the same age to be depressed. Older men are also at much higher risk for suicide and, as with women, they are at risk for health complications of depression. Some evidence suggests that men are more apt than women to mask their depression by using alcohol, which may result in a lower reported (but not actual) incidence of depression in men. Some experts suggest that men with depression might be identified with the following indicators:

Low tolerance to stress
Behaviors such as "acting out" and being impulsive
A history of alcohol or substance abuse
A family history of depression, alcohol abuse, or suicide

Depression is less reported in the male population, but this may be caused by male tendency to mask emotional disorders with behavior such as alcohol abuse.

Depression in Children and Adolescents. Children ages 12 - 16 are at high risk for depression. Studies suggest that 3 – 5% of children and adolescents suffer from depression, and 10 – 15% have some depressive symptoms. Depression before puberty is more likely to occur in boys and after puberty in girls.

Depression in Adults. Surveys indicate that depression usually begins around the age of 30, although people do not generally seek treatment until they are about 33 years old. Statistics also suggest that depression is becoming more common among middle-aged people ages 45 - 64. According to a 2005 survey, middle-aged adults have the highest lifetime risk for depression.

Depression in the Elderly. Studies suggest that 5 – 14% of the elderly population suffer from some form of depression. In addition, the elderly are highly vulnerable to suicide. Elderly people comprise 13% of the U.S. population but account for 18% of all suicide deaths.

The role of society and economics has specific implications for women. [See Depression in Women.] Being in a low socioeconomic group is a major risk factor for depression in anyone. Money, of course, allows greater access to good medical care, but this factor does not fully explain the higher rates of depression in impoverished people. People at any income level are likely to be depressed if they have poor health and are socially isolated. Some studies suggest that Western cultural attitudes that link income to social status may play a significant role in the connection between poverty and depression:

In one British study, actual poverty or unemployment increased the duration of any existing depression, but it did not appear to play any important causal role. Feelings of financial insecurity, however, both caused and prolonged depression.
Another study reported that Mexican adults who immigrated to America had half the psychiatric illnesses as did Mexican-Americans born in the U.S., regardless of their income. But the longer the immigrants lived in the U.S., the greater their risk for psychiatric problems. Traditional influences of Mexican culture and social ties appeared to protect newly arrived immigrants from mental illness, even when they were poor. Eventually, however, the consequences of Americanization added to poverty and led to feelings of alienation and inferiority.

Depression in family members increases the risk for depression in other family members. Studies report that depression for even 1 - 2 months in a mother increases the risk for depression in her children. The more severe the maternal depression, the higher the risk for depression in the children. In a perpetuating cycle, being depressed as a child increases the risk for depression during adulthood. In such cases, genetic or environmental factors or both may be responsible. Spouses of partners with depression are themselves at higher risk for depression.

Patients who have had serious bouts of depression usually cite a stressful life event as the precipitating factor for their illness. Adverse events during childhood pose a higher risk for depression in adulthood. In one study, parental divorce, physical abuse, and frightening experiences were particularly associated with onset of depression in adulthood. Only divorce was associated with recurrence, however.

Adverse events in adulthood also trigger depression. Losing a spouse through divorce or death is a major risk factor for depression in anyone. In fact, recent loss of a loved one is the most frequently reported precipitant of acute depression. All major (and even minor) losses, however, cause grief reactions. People who develop acute or chronic depression after a loss may have predisposing factors, including genetic or biologic ones, which make them more vulnerable. The existence or absence of a strong social network of family, friends, or both also has a major positive or negative effect, respectively, on recovery. Most people are able to cope with the emotional pain and eventually move beyond it without becoming chronically depressed. [See Ruling out Grief and Loneliness in the diagnosis section of this report.]

Traumatic events such as abuse or even natural disasters can cause severe immediate or delayed depression from which recovery takes a long time.

Severe or Chronic Medical Conditions. Any chronic or serious illness that is life-threatening or out of a person's control can lead to depression.

Thyroid Disease. Hypothyroidism (a condition caused when the thyroid gland does not produce enough hormone) can cause depression. However, hypothyroidism may also be misdiagnosed as depression and go undetected.

Chronic Pain Conditions. Studies have reported a strong association between depression and headaches, including chronic tension-type and migraine. Some experts believe that a syndrome of migraine headaches (and also possibly tension-type), anxiety, and depression is caused by common factors, such as abnormalities in chemical messengers, particularly dopamine or serotonin. Fibromyalgia and other chronic pain syndromes are also associated with depression.

Stroke and Other Neurological Conditions. Having a stroke increases the risk of developing depression. Also, patients with Parkinson's disease, spinal cord injuries, and other similar problems that impair movement or thinking are associated with depression.

Heart Failure. Patients with heart failure or patients who have suffered a heart attack may also suffer from depression.

A number of drugs taken for chronic problems cause depression. Among them are pain relievers for arthritis, cholesterol-lowering drugs, medications for high blood pressure and heart problems, and bronchodilators used for asthma and other lung disorders.

There is a significant association between cigarette smoking and a susceptibility to depression. People who are prone to depression face a 25% chance of becoming depressed when they quit smoking, and this increased risk persists for at least 6 months. What's more, depressed smokers are unlikely to stop smoking. Only about 6% remain smoke-free after a year. Smokers with a history of depression are not encouraged to continue smoking, but rather to keep a close watch on recurrence of depressive symptoms if they do stop smoking. The antidepressant bupropion (Wellbutrin), which is approved for helping people quit smoking (marketed under the name Zyban), is proving to be very useful in helping smokers to quit.

Chronic depression is a frequent companion to anxiety disorders. In one study, up to 96% of patients with depressive disorders experienced concurrent anxiety. More than two-thirds of people with obsessive-compulsive disorder, a common anxiety disorder, also suffer from depression.

Some evidence suggests that certain personality styles, which include an intense need for close relationships and concern for disapproval or need for control, pose a high risk for depression, particularly after an adverse life event. In line with these findings, the following specific personality disorders have been associated not only to a first episode of depression, but also to relapses:

A person with borderline personality disorder acts impulsively and has a poor self-image and unstable relationships. In one study, patients with borderline personality disorder and major depression were more likely than those with either condition alone to plan and attempt suicide.
An individual with an avoidant personality avoids strangers and unfamiliar situations.

(Personality disorders, as opposed to emotional disorders, are those with abnormal behavioral patterns rather than abnormal emotions.)

Sleep abnormalities are an integral part of depressive disorders, with more than 90% of depressed patients experiencing insomnia. Although stress and depression are major causes of insomnia, insomnia may also increase the activity of the hormones and pathways in the brain that can produce emotional problems. Even modest alterations in waking and sleeping patterns can have significant effects on a person's mood. Persistent insomnia may even predict the future development of emotional disorders. Some experts think that some psychiatric disorders can be prevented by early recognition and treatment of insomnia.

Seasonal affective disorder (SAD) affects about one in 20 adults. About 80% of people who suffer from SAD are women. People who live in the north are more apt to experience SAD than people who live in southern latitudes.

Complications of Depression

Depression is often chronic, with episodes of recurrence and improvement. About one-third of patients with a single episode of major depression will have another episode within 1 year after discontinuing treatment, and more than 50% will have a recurrence at some point in their lives. Depression is more likely to recur if the first episode was severe or prolonged, or if there have been recurrences. To date, even newer antidepressants have failed to achieve permanent remission in most patients with major depression, although the standard medications are very effective in treating and preventing acute episodes.

About 90% of suicides are due to treatable disorders, most commonly depression or substance abuse. People with depression have up to a 15% risk for suicide, with the highest risk in patients who are hospitalized for depression. Some studies indicate that atypical depression poses a higher risk for suicide than typical depression and that dysthymia may pose a higher risk than episodic major depressive disorder. Depressed men are more likely to commit suicide than depressed women. Around the world, suicide is most common in men older than 60. Suicidal preoccupation or threats of suicide should always be treated seriously in anyone, however. [See Depression in the Elderly or Depression in Children in this report.]

Major depression in the elderly or in people with serious illness seems to reduce their survival rates, even independently of any accompanying illness. Decreased physical activity and social involvement certainly play a role in the association between depression and illness severity.

Effect on Heart Disease and Other Age-Related Problems. Many studies report strong associations between depression and a worse and even shorter old age. Depression is also associated with mental decline in older people.

Studies are now showing that depression may contribute to poor outcomes for patients with heart disease.

Obesity. Both obesity and depression are increasing in Americans. Adolescents who are depressed have a high risk for obesity. Conversely, obese people are about 25% more likely than non-obese people to develop depression or other mood disorders. The conditions may have common risk factors. For example, being in a lower social and economic group increases the risk for both obesity and depression. Low physical activity may also be a common factor.

Increasing Sensations of Pain. Depression coincides with increased pain in people with conditions such as those arthritis or fibromyalgia.

Cancer. The relationship between depression and cancer has been explored for years with only a few clear-cut associations. Certainly depression and anxiety can have a profound impact on quality of life in cancer patients.

Effects of Parental Depression on Children. Depression in parents can have profound effects on their children and may increase the risk for childhood depression.

Effects on Marriage. In one survey, nearly half of people who suffered from psychiatric disorders before or during their first marriage were divorced, compared to a divorce rate of 36% in those who never suffered from emotional disorders. Spouses of partners with depression are themselves at higher risk for depression.

Effect on Work. Depression is well-known to adversely affect a person's work life. It significantly increases the risk for unemployment and lower income. Nearly half of the nation's excess lost productive time (in most cases because of reduced performance at work) may be a result of depression. Workers with depression also lose significantly more time due to ill health than non-depressed workers. Such lost time is estimated to cost the country billions of dollars each year.

Alcohol and Drug Abuse. About 14% of people with major depression also have an alcohol use disorder and 5% have drug abuse problems. Studies on the connections between alcohol dependence and depression have still not resolved whether one causes the other or if they both share some common biologic cause.

Smoking. Depression is a well-known risk factor for smoking, and 26% of people with major depression are nicotine dependent. Nicotine may stimulate receptors in the brain that improve mood in certain people with genetically induced depression.

Diagnosis

Most people who are depressed do not seek psychiatric help and must rely on their family doctor. Unfortunately, it is often difficult for a primary care doctor to recognize the problem if the patient does not bring it up directly.

Patients themselves may be unable to sense or admit their own depression. In one study, although 21% of patients who visited their family doctors were depressed, only 1% described their problem as depression.

Depression can also be confused with other medical illnesses. Weight loss and fatigue, for example, accompany many conditions, some serious, but they can also occur with depression.

Although not all patients who visit their doctor should be screened for depression, individuals who have certain factors might ask their doctor if they should be screened for depression. For example, the following people may be at higher risk and therefore warrant a screening test:

People with a family or personal history of depression
Patients with multiple medical problems
Patients with physical symptoms that have no clear medical cause
Patients with chronic pain
Individuals who visit their doctor more frequently than expected

A mental health specialist, such as a psychiatrist, social worker, or psychologist, is the best source for a diagnosis of depression. Such health professionals may administer a screening test such as the Beck Depression Inventory or the Hamilton Rating Scale, both of which consist of about 20 questions that assess the individual for depression. Studies are finding that even computerized phone interviews are valuable as screening tools for depression. However, most mental health professionals generally diagnose depression based on symptoms and other criteria.

Specific ethnic groups may present different symptoms of depression. People from non-Western countries are more apt to report physical symptoms (such as headache, constipation, weakness, or back pain) related to the depression, rather than mood-related symptoms.

Grief. The symptoms of grief (bereavement) and depression have much in common; indeed, it may be difficult to separate the two. Grief, however, is considered to be a healthy and important emotional response for dealing with loss, and it generally follows a characteristic path:

Grief normally has a limited duration. In people without any co-existing emotional disorder, bereavement usually lasts between 3 - 6 months.
The grieving person typically endures a succession of emotions that include shock and denial, loneliness, despair, social alienation, and anger.
The recovery period following this process, during which the individual becomes re-involved with life, takes about the same amount of time as the bereavement cycle.

If the grief is still severe after this period, however, it may affect a person's health or increase the risk for on-going depression. Some experts suggest that such a severe persistent grieving state be categorized as a separate psychologic diagnosis, termed complicated grief disorder, which would be related to post-traumatic stress syndrome and require special treatment.

Loneliness. Like grief, loneliness is a condition that may often be mistaken for depression. In fact, while loneliness and depression often go hand in hand, some researchers believe that some people with loneliness may be effectively treated for depression. Of course, every person feels loneliness now and then. Debilitating loneliness, however, is often characterized by misery, a feeling of hollowness, unrealistic expectations for one's life, and feeling removed from others. Shy people may be more prone to loneliness. Psychotherapy of various kinds may help people address and allay loneliness.

Treatment

Depression is a treatable illness, with many therapeutic options available. Increasingly, professionals are viewing major depression as a chronic illness (the condition nearly always returns when treatment is stopped). Therefore, medical intervention and help must be ongoing.

Patients with chronic depression have a number of options, including psychotherapy, antidepressants, or both. In general, the treatment choice depends on the degree and type of depression and other accompanying conditions. It also may depend on age, pregnancy status, or other individual factors.

Unfortunately, many Americans with major depression receive either inadequate treatment or no treatment at all. Reasons may include treatment by providers who may not have sufficient information or training on dosages or specific drugs that would be best suited for individual cases, lack of recognition of depression symptoms by providers, poor access to health care services, lack of health insurance, and poor compliance with medications.

Patients with Major Depression. Numerous studies support a combination of cognitive behavioral therapy (CBT) plus antidepressants, typically a selective serotonin reuptake inhibitor (SSRI) or serotonin norepinephrine reuptake inhibitor (SNRI). Although some people may feel better after taking antidepressants for a few weeks, most people need to take medication for at least 6 - 12 months to ensure a full response. Research indicates that patients respond better to medications when drug therapy is combined with CBT. Exercise is also important in helping relieve depressive symptoms.

For patients who are not helped by SSRIs or SNRIs, other types of antidepressants are available. Sometimes an atypical antipsychotic drug may be given in combination with an antidepressant for patients with severe major depressive disorder.

Brain stimulation techniques, such as electroconvulsive therapy (ECT) and vagus nerve stimulation, are also options. In recent years, experimental procedures, such as repetitive transcranial magnetic stimulation, have also been found to help in some cases of treatment-resistant depression. Researchers are also investigating new types of drugs (such as ketamine), which may provide a rapid, if temporary, improvement for these patients. In general, the more treatment strategies that patients need, the less likely they are to recover completely from depression.

Patients with Minor Depression. Patients with minor depression (fewer than five symptoms that persist for fewer than 2 years) may respond well to watchful waiting to see if antidepressants are necessary. Some studies indicate that antidepressants do not work that well for mild depression. Counseling or cognitive behavioral therapy may be helpful, as is regular exercise.

Patients with Depression and Other Psychiatric Problems. Other psychiatric problems often coexist with depression. If patients also suffer from anxiety, treating the depression first often relieves both problems. More severe psychiatric problems, such as bipolar disorder or schizophrenia, require specialized treatments.

Patients with Depression and Medical Conditions. Depression can worsen many medical conditions and may even increase mortality rates from some disorders, such as heart attack and stroke. Depression, then, should be aggressively treated in anyone with a serious medical problem.

Patients with Depression and Substance Abuse Problems. Treating depression in patients who abuse alcohol or drugs is important and can sometimes help patients quit. However, absence from substance abuse is considered essential for adequate treatment of depression.

Most people with depression can be treated in an office setting by a psychiatrist or other therapist. Infrequently, the level of dysfunction may be serious enough to warrant hospitalization to provide protection from further deterioration or self-harm.

Health professionals who can prescribe antidepressants include:

Doctors, including psychiatrists
Some nurse clinicians

Although other mental health professionals cannot prescribe drugs, most therapists have arrangements with a psychiatrist for providing medications to their patients. In general, mental health professionals are categorized by their training:

Psychoanalysts tend to have a degree in psychiatry, psychology, or social work as well as several years of training at a psychoanalytic institute.
Psychologists have received a Ph.D, including an internship in a mental healthcare facility.
A clinical social worker has a master's degree and 2 years of supervised experience in mental health and human services.
Advanced-practice psychiatric nurses have a master's degree and can provide therapeutic services.

Tips for Selecting a Therapist:

Patients can locate a mental health professional in their area by asking their doctor for a referral or by contacting a mental health organization. [See Resources.]
The patient should describe problems briefly but specifically over the phone to any prospective therapist to get a sense of whether he or she will suit the patient's needs.
An advanced degree does not necessarily guarantee quality therapy. The patient's belief in their health care provider may be the most important component in recovery.
Patients should not be shy about considering a change in their therapist if they lack confidence in their current one.

Although a mother's depression during and after pregnancy can have serious effects on her child, researchers are still trying to determine the best methods for preventing and treating pregnancy-related depression.

The use of antidepressants during pregnancy is controversial, especially for women with major depression who regularly take antidepressant medication. Most doctors advise women to avoid, if possible, any medications during pregnancy and nursing. But, women with depression who stop taking antidepressants during pregnancy may be likely to have a relapse of depression. Women who are pregnant or thinking about becoming pregnant should not stop taking antidepressants without first talking to their doctors.

Some research suggests that certain serotonin reuptake inhibitors (SSRIs) may increase risks for the fetus. The strongest evidence concerns the SSRI paroxetine (Paxil), which can cause major birth defects -- including heart abnormalities -- if taken during the first trimester of pregnancy. In 2006, the American College of Obstetricians and Gynecologists recommended that doctors should not prescribe paroxetine to women who are pregnant or planning on becoming pregnant.

Other research indicates that first-trimester use of SSRIs may increase the risk for rare skull and neural tube defects. Venlafaxine (Effexor), a dual inhibitor antidepressant, has been associated with birth complications when taken during the last trimester. In addition, some studies have shown that babies may experience withdrawal symptoms if their mothers take SSRIs late in pregnancy. However, the overall evidence indicates that there is a very low overall risk for antidepressant-associated birth defects and problems. Still, women should discuss all potential risks with their doctors.

In terms of non-drug treatment of postpartum depression, a review of 15 clinical trials suggested that postpartum depression is best treated by intensive and individualized psychotherapy within a month after a woman gives birth. The researchers found that women are too busy in the weeks before birth to attend prenatal classes that focus on preventing postpartum depression.

Some experts recommend only psychotherapy or attention intervention for elderly patients with mild depression. In many older patients, a regular exercise program may be sufficient to improve mood. Ideally, elderly people with more serious depression should be treated with a combination of psychotherapy and antidepressants on an ongoing basis, even after their depressive symptoms are relieved.

The use of antidepressants in the elderly is problematic:

Tricyclics are as effective as, and less expensive than, SSRIs, but they have more side effects. Specifically, they pose a higher risk for adverse effects on the heart and possibly the lungs. (The older tricyclics, such as amitriptyline and imipramine, have other severe side effects in older adults.)
SSRIs have fewer side effects than tricyclics. However, SSRIs may not pose any lower risk for falls than the older tricyclic antidepressants. In addition, researchers are investigating whether SSRIs are associated with an increased rate of osteoporosis (“thin bones”) and fractures in older adults.

About 2% of American primary school-age children and 4 - 8% of adolescents suffer from depression. Studies suggest that when children or adolescents are treated, up to 80% recover. Still, 25 - 50% of these young people have a recurrence of depression within 2 years of their first episode of depression.

It is important to recognize that childhood depression differs from adult depression and that children may respond differently than adults to antidepressant medication. These variances are due to childhood brain development processes as well as age-related differences in drug metabolism. Children may experience medication side effects not seen in adults, and some antidepressants that are effective for adults may not work for children.

Mild-to-Moderate Depression. The pediatrician may want to monitor a child with mild depression for 6 - 8 weeks before deciding whether to prescribe psychotherapy, antidepressant medication, or a referral to a mental health professional. Once medication has been started, the doctor will decide if the dosage needs to be increased after another 6 - 8 weeks. Medication may need to be continued for 1 year after the symptoms have resolved, and the doctor should continue to monitor the child on a monthly basis for 6 months after full remission of depression. For psychotherapy, cognitive therapy may be the best approach for children and adolescents with depression. Some studies suggest that other types of psychotherapy, such as family therapy and supportive therapy, can also be very effective.

Severe Depression. The American Academy of Child and Adolescent Psychiatry recommends an SSRI antidepressant for children and adolescents with very severe depression that does not respond to psychotherapy. Tricyclic antidepressants do not tend to help adolescents and children and these drugs have many side effects. MAOIs are also not commonly prescribed.

Many SSRIs appear to be safe and effective, but at this time fluoxetine (Prozac) is the only one approved for children over age 7 and for adolescents. The FDA strongly advises against the use of specific SSRIs, such as paroxetine (Paxil), due to concerns about an increased risk for suicidal behavior as well as the lack of any evidence supporting the drug's efficacy in pediatric patients. On an encouraging note, a 2007 review in the Journal of the American Medical Association indicated that the overall benefits of antidepressants for children and adolescents appear to be much greater than the risks for suicidal behavior. Still, the study found that antidepressants have only modest benefits for major depressive disorder, which underlines the importance of adjunctive psychotherapy.

For optimal results, SSRIs should be combined with either cognitive-behavioral or interpersonal psychotherapies. A study of adolescents with depression reported that combination treatment with fluoxetine and cognitive behavioral therapy was more effective than either treatment alone.

Due to potential suicide risks, children and adolescents should be monitored regularly during the initial months of antidepressant treatment. [For more detailed information, see Suicide Risk and Antidepressant Medications.]

Antidepressants and Drug Treatment Guidelines

Major classes of antidepressants include:

Selective serotonin-reuptake inhibitors (SSRIs). These have become the standard antidepressants. They target the brain chemical (neurotransmitter) serotonin. They are effective and have very moderate side effects. Some may be beneficial in treating anxiety and certain subtypes of depressive disorders unresponsive to previous drugs, including premenstrual dysphoric disorder and seasonal affective disorder, atypical depression, and recurrent brief depression.
Other neurotransmitter inhibitors. These drugs target neurotransmitters other than or in addition to serotonin, such as norepinephrine. Many are proving to be effective in patients who do not respond to standard antidepressants or in specific patients, such as smokers who want to quit or patients with chronic pain.
Tricyclic antidepressants (TCAs). These drugs are effective but can have severe adverse effects, particularly in older people.
Monoamine oxidase inhibitors (MAOIs). These drugs include newer selective MAOIs. MAOIs are the most effective antidepressants for atypical depression, but have some severe side effects and require restrictive dietary rules.
St. John's wort and other herbal remedies are included in the Lifestyle section of this report.

Approach and Duration of Initial Treatment. The guidelines for the duration of an initial antidepressant regimen is as follows:

Patients should start at a low dose, which is increased over a period of 5 - 10 days.
Patients should see their doctor every 1- 2 weeks until substantial improvement occurs. It may take 4 - 8 weeks before a patient experiences the effects of any antidepressant.
Side effects usually diminish within 1 - 4 weeks. (Exceptions may be weight gain and sexual dysfunction.)
If no improvement occurs, an alternative drug may be tried. More than 80% of patients respond to some antidepressant, although specific drugs are helpful for only about half of patients. This suggests that if one medication fails, another has a good chance of being helpful. In general, the fewer drug treatment strategies required, the better a patient’s chances of recovering completely from depression. Patients who become symptom-free have the best chance for complete recovery compared to patients whose symptoms merely improve.
In general, patients should continue taking antidepressants for at least 6 months after symptom relief to help prevent relapse. (Patients who improve within 2 weeks of taking medications may not require lengthy treatment.)

Treating Recurrence. Recurrence of depression is very common. About a third of patients will relapse after a first episode within a year of ending treatment, and more than half will experience a recurring bout of depression at some point during their lives. Among those at highest risk for early relapse and who may require ongoing antidepressants are:

Patients with at least two episodes of major depression or major depression that lasts for 2 years or longer before initial treatment.
Patients who continue to have low-level depression for 7 months after starting antidepressant treatments.

Patients may need maintenance therapy. Experts disagree, however, on the optimal length or the appropriate dosage of maintenance therapy. Some patients may need to stay on antidepressants for 1 - 2 years -- or even indefinitely. Some experts recommend withdrawing from medication after a year. (This should be done gradually, over 2 - 3 months.) If depression recurs, the patient should go back on the antidepressants.

There is no risk for addiction with current antidepressants, and many of the common antidepressants, including most standard SSRIs, have been proven safe when taken for a number of years.

Common Side Effects of Most Antidepressants. No matter how well a drug treats depression, the ability of the patient to tolerate its side effects strongly influences their compliance with therapy. Lack of compliance is probably the major barrier to success. Side effects can be avoided or moderated if any regimen is started at low doses and built up over time. Although specific side effects are discussed under individual drugs, there are a few that are common to many of them:

Sexual dysfunction is a common side effect of many of the standard antidepressants and some of the newer drugs. These side effects can be particularly distressing for patients on maintenance treatment who otherwise feel well. Some of the newer antidepressants, such as bupropion, may be effective alternatives without as high a risk for this problem. Sildenafil (Viagra), used for erectile dysfunction in men, may help reverse sexual dysfunction from antidepressants. It does not heighten sexual interest, however.
An increased risk of oral health problems caused by dry mouth is associated with long-term use of most antidepressants. Patients can increase salivation by chewing gum, taking vitamin C tablets, using saliva substitutes, and rinsing the mouth frequently.
Virtually all antidepressants have complicated interactions with other drugs; some are very important. Patients should inform the doctor of any drugs they are taking, including over-the-counter medications and herbal remedies.
Nearly all antidepressants are metabolized in the liver, so anyone with liver abnormalities should use them with caution.
Abrupt withdrawal from many antidepressants can produce severe side effects; no antidepressant should be stopped abruptly without consultation with a doctor.

In recent years, there has been concern that SSRI antidepressants may increase the risk for suicidal behavior. Of particular concern is a greater risk for suicide in young people taking these medications. While depression is itself the major risk factor for suicide, and antidepressant medication may revitalize suicidal attempts in patients who were too despondent before treatment to make the effort, evidence suggests that in some cases the medication itself can cause suicidal behavior. One specific SSRI, paroxetine (Paxil), has been definitely linked with suicidal behavioral risk in adults ages 18 - 30. In May 2006, the drug’s manufacturer warned doctors that all patients, and particularly young adults, should be carefully monitored during paroxetine therapy.

The U.S. Food and Drug Administration (FDA) has been conducting in-depth research on suicide risk and antidepressant medications. In October 2004, after careful review of scientific evidence, the FDA issued a public health advisory instructing drug manufacturers to include a "black box" warning explaining the association between antidepressant use and increased risk for suicidality (suicidal thoughts and behavior) in children and adolescents. In May 2007, the FDA proposed that the labels of antidepressant medications should include additional warnings about the risk of suicidal thoughts and behavior in young adults (ages 18 - 24) during the first 1 - 2 months of treatment. The FDA also notes there is a decreased risk of suicidality for adults age 65 years and older taking antidepressants.

The FDA based its recommendations for children and adolescents on a review of 24 clinical trials of nine antidepressant drugs. These trials enrolled over 4,400 pediatric patients and tested the safety and efficacy of SSRIs as well as other classes of antidepressants. The data suggested a greater risk for suicidality within the first few months of treatment. The average risk was minimal. Children and adolescents treated with these drugs had a 4% risk for suicidality compared with 2% for patients who received placebo. No patients in these studies actually committed suicide.

Based on these findings, the FDA recommends that caregivers monitor children being treated with antidepressants for sudden behavioral changes, and immediately notify their doctor if such changes occur. These behavioral signs include:

Agitation
Irritability
Anxiety
Panic attacks
Insomnia
Aggressiveness
Impulsivity
Hyperactivity in actions and speech
Worsening of depression
Increased thoughts of suicide

The FDA’s guidelines for medication usage recommend that patients see their doctor regularly after initiating drug treatment. The recommended schedule is:

Once per week for 4 weeks (1st month)
Every 2 weeks for the next month (2nd month)
At the end of week 12 following the start of drug treatment (3rd month)
More frequently if changes in mood or behavior occur
Patients should also be closely monitored if their drug dosage is changed.

Patients should immediately contact their doctor if depression symptoms worsen or if suicidal thoughts or behavior increase.

Selective serotonin-reuptake inhibitors (SSRIs) are now the first-line treatment of major depression. They work by increasing levels of serotonin in the brain. SSRIs include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), fluvoxamine (Luvox), citalopram (Celexa), and escitalopram (Lexapro). There are no significant differences among SSRI brands in effectiveness for treating major depressive disorder, although individual drugs may have different side effects or benefits for specific patients. At this time, fluoxetine is the only one of these drugs to be approved for children over age 7 and adolescents.

Because they act specifically on serotonin, SSRIs have fewer side effects than older antidepressants, which have more widespread effects in the body.

Candidates for SSRIs. SSRIs appear to help people with the following conditions:

Mild to moderately severe major depression
Seasonal affective disorder
Dysthymia
Severe premenstrual syndrome and premenstrual dysphoric disorder (PMDD) -- a repackaged form of fluoxetine (Sarafem) is the first SSRI specifically FDA-approved for PMDD. Other SSRIs and newer antidepressants are also proving to be effective
Anxiety disorders
Bulimia
Impulsive and aggressive behaviors in psychiatric patients and in people with no mental health problems

Duration of Effectiveness and Use. SSRIs take, on average, 2 - 4 weeks to be effective in most adults. They may take even longer, up to 12 weeks, in the elderly and in those with dysthymia. By 14 weeks, depression should be in remission in everyone who responds to the drugs. Unfortunately, recurrence is common once the drugs are stopped. Studies indicate that the standard SSRIs are generally safe, although it is still unclear which patients would most benefit from on-going medication. Some doctors recommend withdrawing from medication after a year. If depression recurs, then the patient should go back on the antidepressant.

Side Effects of SSRIs. Side effects may include:

Nausea and gastrointestinal (GI) symptoms usually wear off over time.
Agitation, insomnia, mild tremor, and impulsivity occur in 10 - 20% of people who take SSRIs. These symptoms may be particularly problematic in patients who also suffer from anxiety, sleeplessness, or both.
Drowsiness affects about 20% of SSRI-treated patients. Newer SSRIs, such as escitalopram (Lexapro), may have fewer of these adverse effects.
Dry mouth is a common side effect.
Patients may lack motivation, feel tired, be confused, and experience mental dullness, but this side effect is fairly rare.
Headache and flu-like symptoms may occur.
Heart palpitations and chest pain may occur.
Weight gain varies depending on the SSRI. For example, in one study patients who took paroxetine (Paxil) experienced five times the weight gain as those who took citalopram (Celexa). Patients should be encouraged to maintain a low-calorie diet and to exercise. They should be aware that some of the weight-loss medications, notably sibutramine (Meridia), can have serious interactions with SSRIs.
Sexual side effects include delayed or loss of orgasm and low sexual drive. They are a well-known side effect of SSRIs. Taking a supervised drug "holiday" on the weekend may improve sexual function during that time. Some of the newer SSRIs or other antidepressants may cause less severe impairment of sexual function.
Paroxetine (Paxil) may cause birth defects if taken during the first 3 months of pregnancy. Most reported defects have been heart-related. The most common heart abnormalities are ventricular septal defects, which are holes in the muscular wall that separate the main pumping chambers of the heart. Venlafaxine (Effexor) has also been associated with birth defects. Still, recent research suggests that most types of SSRI-associated birth defects are rare and the overall risks are low. Pregnant women who are being treated for major depression should not stop taking antidepressants without first talking to their doctors. [For more information on antidepressant treatment guidelines during pregnancy, see Treating Depression During and After Pregnancy in Treatment section.]

Drug Interactions. SSRIs can interact with other antidepressants such as tricyclics and, in particular, monoamine oxidase inhibitors (MAOIs). SSRIs should never be taken in combination with an MAOI or within 2 weeks after discontinuing MAOI treatment. Other serious interactions have occurred with meperidine (Demerol) and illegal substances (such as LSD, cocaine, or ecstasy). People who take SSRIs may drink alcohol in moderation, although the combination may compound any drowsiness experienced with SSRIs, and some SSRIs increase the effects of alcohol.

Withdrawal Symptoms. Cognitive problems, sleep disturbances, increase in depressive symptoms, and electric shock-like symptoms have been known to occur with sudden discontinuation of SSRIs. The symptoms are more likely to occur with antidepressants with shorter half-lives as compared with fluoxetine, which has a long half-life. The dose of the antidepressant should be slowly reduced before stopping.

These newer antidepressants target other neurotransmitters, such as norepinephrine or dopamine, alone or in addition to serotonin. In general, the advantages of the new designer antidepressants are:

They may be better tolerated than the older tricyclic compounds and even some SSRIs, although long-term side effects are not fully known in this group.
Most of these drugs have fewer adverse effects than SSRIs on sexual function.
They may be more effective than SSRIs for severely depressed patients.
Some of these drugs are helpful for additional problems -- such as insomnia, fibromyalgia and similar chronic pain syndromes, or smoking -- that may affect people with depression.

They do share some side effects with other antidepressants, including dizziness and dry mouth.

Dual Inhibitors. Dual inhibitors act directly on two neurotransmitters -- norepinephrine and serotonin. These drugs are also known as serotonin norepinephrine reuptake inhibitors (SNRIs). The following SNRIs are approved for treatment of major depression in adults:

Venlafaxine (Effexor) is similar to Prozac in effectiveness and tolerability for most patients. As with SSRIs, venlafaxine may impair sexual function. The drug can increase blood pressure and heart rate and should be used with caution in patients with high blood pressure or heart disease. It can also cause uterine and vaginal bleeding unrelated to menstruation. Venlafaxine should not be taken during the last trimester of pregnancy as it can cause complications in newborn infants. Some patients report severe withdrawal symptoms, including dizziness and nausea. In 2006, the drug’s manufacturer warned of an increased overdose risk and advised doctors to prescribe their patients only small amounts of venlafaxine pills.
Duloxetine (Cymbalta) also acts on both serotonin and norepinephrine. Side effects are generally mild and include dry mouth, nausea, and sleepiness. Patients with narrow-angle glaucoma or patients with liver or kidney diseases should not take duloxetine. Because duloxetine can cause liver damage, patients who drink large quantities of alcoholic beverages should not take it. Signs of liver damage include itching, dark urine, yellowing of skin and eyes (jaundice), and fatigue. Patients should immediately contact their doctor if they experience these symptoms.
Mirtazapine (Remeron) can cause sleepiness, increased appetite, weight gain, and dizziness.

Other Antidepressants with Effects on Multiple Neurotransmitters. Bupropion (Wellbutrin, Zyban) affects the reuptake of serotonin, norepinephrine, and dopamine -- a third important neurotransmitter. In addition to depression, bupropion is also approved for smoking cessation and for treating seasonal affective disorder (SAD). Bupropion causes less sexual dysfunction than SSRIs. About 25% of patients experience initial weight loss. Side effects include restlessness, agitation, sleeplessness, headache, and stomach problems. Bupropion has a risk for seizures, which increases with higher doses. High doses may also cause dangerous heart arrhythmias.

Before the introduction of SSRIs, tricyclics were the standard treatment for depression.

Tricyclics are sometimes grouped into two categories:

Tertiary amines include amitriptyline (Elavil, Endep) and imipramine (Tofranil).
Secondary amines include desipramine (Norpramin) and nortriptyline (Pamelor, Aventyl). Secondary amines may have fewer side effects, including drowsiness, than tertiary amines, but they are as toxic in high amounts.

Less commonly used tricyclics include doxepin (Sinequan), amoxapine (Asendin), maprotiline (Ludiomill), protriptyline (Vivactil), trimipramine (Surmontil), mianserin (Bolvidon), and dothiepin (Prothiaden).

Tricyclics are as effective for treating depression but they have many side effects. They may offer benefits for many people with dysthymia, who generally do not respond to SSRIs. They may also be prescribed in lower dosages to be taken at night to help with insomnia.

Side Effects of Tricyclics. Side effects are common with these medications. In fact, in an analysis of studies, more tricyclic users discontinued their drugs due to side effects than did SSRI or MAOI users. Those most often reported include:

Dry mouth
Constipation
Blurred vision
Sexual dysfunction
Weight gain
Difficulty urinating
Drowsiness
Dizziness -- blood pressure may drop suddenly when sitting up or standing.

Tricyclics can have serious, although rare, side effects:

They tend to cause disturbances in heart rhythm, which can pose a danger for some patients with certain heart diseases. Care should be taken when these medications are prescribed to the elderly and to those at risk of overdose.
Also of concern are reports that tricyclics, particularly imipramine as well as mianserin and dothiepin, may increase the risk for a lung disease called idiopathic pulmonary fibrosis (IPF), which can cause lung inflammation and scarring. Initial symptoms are breathlessness and dry cough.
Tricyclics can be fatal with an overdose.
Protriptyline can cause sun sensitivity. People who take this drug should take precautions against sunlight when they go outdoors.

Monoamine oxidase inhibitors (MAOIs) block monoamine oxidase, an enzyme which has negative effects on many of the neurotransmitters that are important for well-being. MAOIs include phenelzine (Nardil), isocarboxazid (Marplan), and tranylcypromine (Parnate). Because these drugs can have very severe side effects, they are usually prescribed only when other types of antidepressants do not help. Research indicates that MAOIs are an effective option for atypical and treatment-resistant depression.

Newer MAOIs, such as selegiline (Eldepryl, Movergan), target only one form of the MAOI enzyme. They may cause fewer side effects than older MAOIs. In 2006, a skin patch form of selegiline (Emsam) was approved for treatment of major depressive disorder in adults.

Candidates for MAOIs. MAOIs may be effective for the following conditions:

Atypical depression
Eating disorders
Post-traumatic stress disorder
Borderline personality

Side Effects. MAOIs commonly cause the following side effects:

Orthostatic hypotension (a sudden drop in blood pressure upon standing)
Drowsiness or insomnia
Dizziness
Sexual dysfunction
The most serious side effect is severe hypertension (high blood pressure), which can be brought on by eating certain foods having high tyramine content. Such foods include aged cheeses, most red wines, sauerkraut, vermouth, chicken livers, dried meats and fish, canned figs, fava beans, and concentrated yeast products.
MAOIs can cause birth defects and should not be taken by pregnant women.

Very dangerous side effects, such as serotonin syndrome, can occur from interactions with other antidepressants, including SSRIs. Serotonin syndrome is a potentially fatal condition that is caused by the interaction of serotonergic drugs. Symptoms include confusion, agitation, sweating and shivering, and muscle spasms. There should be at least a 2-week break between taking MAOIs and other antidepressants. MAOIs can have serious interactions with other drugs as well, including some common over-the-counter cough medications. In such cases, severe high blood pressure or dangerous reactions can occur. It is important that patients discuss with their doctors any other medications they are taking.

If patients fail to respond to antidepressants, doctors may try adding on a different type of drug. (This combination strategy is called “augmentation” or “adjunctive treatment”.) Atypical antipsychotics are drugs that are usually prescribed for schizophrenia or bipolar disorder, but they can also play a role in the treatment of severe depression. In 2007, aripiprazole (Abilify) was approved in combination with antidepressant therapy for treatment of adults with major depressive disorder. Investigators are also studying whether combination treatment with the atypical antipsychotic risperidone (Risperdal) can help patients with major depression achieve remission.

Ketamine. Ketamine, an anesthetic drug, may be helpful for patients with severe treatment-resistant depression. In a small preliminary study, a single intravenous dose of ketamine helped patients quickly recover from depression within 2 hours, and some patients sustained benefits for up to a week. (Standard antidepressant drugs usually take about 8 weeks to have an effect.) Ketamine blocks the NMDA brain protein receptor, which is involved in glutamate regulation. Glutamate is a brain chemical that is thought to be involved in depression.

Psychotherapy

Among the various psychotherapies, cognitive-behavioral therapy appears to be the most effective approach. If psychotherapy is used alone without medications, benefits should be evident within 8 weeks and symptoms should be fully resolved by 12 weeks. If these conditions are not met, then the patient should strongly consider antidepressant drugs.

In a major analysis of four randomized comparative studies, cognitive behavior therapy worked as well as antidepressants in treating severe depression for many patients. Much of the success of psychologic therapy depends on the skill of the therapist. Many studies suggest that combining cognitive therapy with antidepressants offer the greatest benefits for many patients, particularly for dysthymia (chronic depression).

Medical evidence also has found that the benefits of cognitive therapy persist after treatment has ended. Cognitive behavioral therapy has been shown to help prevent future suicide attempts in patients with a history of suicidal behavior.

Best Candidates. Cognitive therapy may be particularly helpful for the following patients:

Patients with atypical depression
Adolescents with mild symptoms of major depression
Women with non-psychotic postpartum depression
Children of parents with the disorder -- in this case, therapy should involve the whole family.
Cognitive therapy does not appear to be as beneficial as antidepressants for most patients with dysthymia.

Approach. This approach focuses on identification of distorted perceptions that patients may have of the world and themselves, on changing these perceptions, and on discovering new patterns of actions and behavior. These perceptions, known as schemas, are negative assumptions developed in childhood that can precipitate and prolong depression. Cognitive therapy works on the principle that these schemas can be recognized and altered, thereby changing the response and eliminating the depression.

First, the patient must learn to recognize depressive reactions and thoughts as they occur, usually by keeping a journal of feelings about, and reactions to, daily events.
The patient is often given "homework" that tests old negative assumptions against reality and demands different responses.
Then, the patient and therapist examine and challenge these entrenched and automatic reactions and thoughts.
As the patient begins to understand the underlying falseness of the assumptions that cause depression, they can begin substituting new ways of coping.

Over time, such exercises help build confidence and eventually alter behavior. Patients may take group or individual cognitive therapy. Cognitive therapy is a time-limited treatment, typically lasting 12 - 14 weeks. Extending this period, however, may help prevent relapse. In one study, therapy was continued for 10 sessions over an additional 8 months. This extended treatment significantly reduced the risk of recurrence. In fact, some experts believe that short-term therapy is not effective for patients with chronic or relapsing psychiatric disorders.

Based in part on psychodynamic theory, interpersonal therapy acknowledges the childhood roots of depression, but focuses on symptoms and current issues that may be causing problems. IPT is not as specific as cognitive or behavioral therapy, and all work is done during the sessions. The therapist seeks to redirect the patient's attention, which has been distorted by depression, toward the daily details of social and family interaction. The goals of this treatment method are improved communication skills and increased self-esteem within a short period (3 - 4 months of weekly appointments) of time. Among the forms of depression best served by IPT are those caused by distorted or delayed mourning, unexpressed conflicts with people in close relationships, major life changes, and isolation.

The intent of supportive psychotherapy or attention intervention is to provide the patient with a nonjudgmental environment by offering advice, attention, and sympathy. Supportive therapy appears to be particularly helpful for improving compliance with medications by giving reassurance, especially when setbacks and frustration occur.

Other Treatments

Electroconvulsive therapy (ECT) is commonly called shock treatment. It has received bad press, in part for its potential memory-depleting effect. Since its introduction in the 1930s, ECT has been significantly refined, and is now considered an effective and safe treatment for severe depression in the appropriate situation. It is especially effective for patients with severe depression who experience delusions and hallucinations. Maintenance ECT may also help prevent relapse.

Candidates for ECT. ECT may be helpful for the following patients with severe depression:

Patients who cannot, for any reason, take antidepressant drugs
Suicidal patients
Elderly patients who are psychotic and depressed
Pregnant women with severe depression
Patients with certain heart problems
Young patients who fit the adult criteria for ECT

The Procedure. In general, hospitalization is not necessary. ECT involves the following steps:

The patient receives a muscle relaxant and short-acting anesthetic.
A small amount of electric current is sent to the brain, causing a generalized seizure that lasts for about 40 seconds.
Most patients receive 6 treatments, spaced every 2 - 5 days. Others receive up to 15 treatments, followed by 6 - 12 additional treatments spaced every other week or longer for another 2 - 4 months.

Side Effects. Side effects of ECT may include temporary confusion, memory lapses, headache, nausea, muscle soreness, and heart disturbances. Concerns about permanent memory loss appear to be unfounded.

Transcranial magnetic stimulation (TMS) uses high frequency magnetic pulses that target affected areas of the brain. This investigational treatment is similar to electroconvulsive therapy (ECT) but, unlike ECT, it is more precise. However, it is not yet clear whether it as effective as ECT. Researchers are continuing to refine rTMS techniques to improve treatment outcomes.

Vagus nerve stimulation (VNS) is a procedure that is effective for certain patients with epilepsy, and is now showing some success in patients with treatment-resistant depression

VNS involves implanting a battery-powered device under the skin in the upper left of the chest. The neurologist programs the device to deliver mild electrical stimulation to the vagus nerve. The two vagus nerves are the longest nerves in the body. They run along each side of the neck, then down the esophagus to the gastrointestinal tract. The vagus nerve travels to areas of the brain that control functions such as sleep and mood.

Studies report response rates of 35 - 46% in appropriate candidates with treatment-resistant depression. VNS is approved by the FDA for long-term treatment of chronic depression in adults who have not responded to typical treatments for their major depressive episode. Patients who use VNS may continue to show improvement in both their depression symptoms and quality of life.

Vagal stimulation can cause shortness of breath, hoarseness, sore throat, coughing, ear and throat pain, or nausea and vomiting. These side effects can be reduced or eliminated by reducing the intensity of stimulation. Long-term studies on patients with epilepsy have reported no serious adverse side effects, although the treatment may cause lung function deterioration in some people with existing lung disease.

The vagus nerves branch off the brain on either side of the head and travel down the neck, along the esophagus to the intestinal tract. They are the longest nerves in the body, and affect swallowing and speech. The vagus nerves also connect to parts of the brain involved in seizures. In many seizures disorders, electrical stimulation of the vagus nerves may help relieve symptoms.

Phototherapy is recommended as treatment for seasonal affective disorder (SAD), particularly for patients who do not wish to try antidepressants.

The Procedure. The procedure is noninvasive and simple. It is best performed immediately after waking in the morning. The patient sits a few feet away from a box-like device that emits very bright fluorescent light (10,000 lux) for about 30 minutes every day.

Some people report mood improvement as early as 2 days after treatment. In others, depression may not lift for 3 - 4 weeks. If no improvement is experienced after that, depressive symptoms will be unlikely to respond to phototherapy. Phototherapy may work best when combined with cognitive behavioral therapy.

Side Effects. Side effects include headache, eye strain, and irritability, although these symptoms tend to disappear within a week. Patients taking light-sensitive drugs (such as those used for psoriasis), certain antibiotics, or antipsychotic drugs should not use light therapy. Patients should be examined by an ophthalmologist before undergoing this treatment.

A surgical technique called cingulotomy interrupts the cingulate gyrus, a bundle of nerve fibers in the front of the brain, by applying heat or cold. A variation of this procedure using MRI scans to guide the surgeon produced long-term improvement in 53 - 78% of patients with severe intractable depression. The procedure is generally safe with few serious complications. It does not affect intellect or memory.

Some small studies have suggested that acupuncture may help in relieving depression. Larger studies are required to confirm its benefits.

Lifestyle Changes

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

St. John's wort (Hypericum perforatum) is an herbal remedy that may help some patients with mild-to-moderate depression. It does not appear to help patients with moderate or severe depression.

The herb St. John's wort is believed to be helpful in relieving mild-to-moderate depression, but should only be taken under a doctor's supervision. Manufacturers of herbal supplements do not need FDA approval to sell the products.

This herbal substance is not regulated, and there is no guarantee of quality in any brands currently available. In fact, in a 2003 study, only 2 of 54 St. John's products bought in Canada and the U.S. contained concentrations of the active ingredients that fell within 10% of the claims on the labels.

The following guidelines are recommended:

People with depression should not use St. John's wort without consulting a doctor. Children and pregnant or nursing women should not take this substance.
People should purchase brands only from well-established manufacturers.
Although no specific dose levels have been established, evidence suggests taking 900 mg daily (300 mg taken 3 times a day or 450 mg taken twice a day).
It takes between 2 - 3 weeks for the herb to have an effect.
St. John's wort should not be combined with other antidepressants. This herb may also interact with other types of medications and increase or decrease their potency. St. John's wort can increase the risk for bleeding when used with blood-thinning drugs. It can also reduce the strength of certain drugs including cancer and HIV treatments.

Side Effects. Side effects are uncommon but may include nausea, dry mouth, allergic reactions, and fatigue. This herb may increase sensitivity to light (photosensitivity). Some people have reported temporary nerve damage after sun exposure, specifically pain and tingling on sun-exposed areas.

Carbohydrates and Tryptophan. Some people report relief from depression by eating foods or diet supplements that boost levels of tryptophan, an amino acid involved in the production of serotonin. There are high-carbohydrate drinks available over the counter that increase tryptophan levels and may alleviate depression associated with premenstrual syndrome for about 3 hours. Simply eating a high amount of carbohydrates, however, is not a solution for depression.

Impurities found in diet supplements containing L-tryptophan itself have caused cases of eosinophilia-myalgia syndrome, a condition that elevates certain white blood cells and can be fatal. Supplements containing L-tryptophan are currently banned in the U.S. by the FDA.

Fish Oil. Some evidence suggests that an imbalance in the ratio of specific fatty acids (omega-6 to omega-3) may increase the risk for depression. Both are polyunsaturated fats, but omega-6 fatty acids are mostly found in corn, safflower, soybean, and sunflower oil whereas omega-3 fatty acids are found in fish oil, canola oil, soybeans, flaxseed, and certain nuts and seeds.

The bottom line may be to increase intake of omega-3 rich foods, such as fish, nuts, and canola oil, and reduce consumption of foods containing omega-6 fatty acids, such as corn and sunflower oils. Such a dietary approach is healthy in any case. Researchers are studying whether eating fish or taking fish oil supplements can reduce depression. Small preliminary studies suggest that these dietary approaches may be helpful for some patients. Scientists are also investigating which type of fish oil compound -- eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) -- provides the greatest benefit.

Omega-3 fatty acids, found in oily fish and flaxseed and canola oils, may be beneficial to people with depression.

Vitamins and Other Supplements. Certain B vitamins have been associated with some protection against depression.

Vitamin B-3 (niacin) is important in the production of tryptophan and is produced from processing vitamin B3 (niacin). Dietary sources of niacin include oily fish (such as salmon or mackerel), pork, chicken, dried peas and beans, whole grains, seeds, and dried fortified cereals.
Vitamin B-12 and calcium supplements may help reduce depression that occurs before menstruation. One study also suggested that calcium might help prevent postpartum depression.
Low levels of folate, a B vitamin, may be associated with depression. Researchers are studying whether folate supplements may help enhance the effectiveness of SSRIs and other antidepressants.

Increasingly studies are reporting major benefits from exercise for people with depression.

Aerobics. Either brief periods of intense training or prolonged aerobic workouts can raise chemicals in the brain, such as endorphins, adrenaline, serotonin, and dopamine that produce the so-called runner's high. And, of course, weight loss and increased muscle tone can boost self-esteem.

Yoga. Yoga practice, which involves rhythmic stretching movements and breathing, may help improve and stabilize mood.

A strong network of social support is important for both prevention and recovery from depression. Support from family and friends must be healthy and positive. One study of depressed women showed, however, that overprotective as well as very distant parenting was associated with a slow recovery from depression. Studies indicate that people with strong spiritual faiths have a lower risk for depression. Such faith does not require an organized religion. People with depression might find solace from less structured sources, such as those that teach meditation or other methods for obtaining spiritual self-fulfillment.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Colorectal cancer -- cancer of the colon and rectum -- is the second most commonly diagnosed cancer in American men and women. Colorectal cancer develops in the digestive system, which processes food for energy and rids the body of solid waste. Together, the colon and rectum form a muscular tube about 5 feet long known as the large intestine. The colon (the first and largest part of the large intestine) absorbs water and nutrients from food and serves as a storage place for solid waste. The waste moves from the colon into the rectum (the final 6 inches of the large intestine) where it passes out of the body through the anus. Cancers affecting either of these organs are called colorectal cancer. Most colorectal cancers arise from benign polyps (abnormal masses of tissue) that begin growing on the inner lining of the colon or rectum. These growths spread very slowly, taking from 10 - 20 years to become cancerous. Once colorectal cancer is diagnosed, the prognosis depends on how far the cancer has spread.

The American Cancer Society estimates that about 150,000 cases of colorectal cancer are diagnosed every year in the United States. Most cases of colorectal cancer occur in people older than 50 years of age. Although colorectal cancer is expected to be responsible for about 56,000 deaths this year, the death rate from this form of cancer has been dropping steadily for the past 15 years. Some researchers speculate that the lowering death rate is due to prevention and early treatment of the disease.

Signs and Symptoms

Unfortunately, most people with colorectal cancer will not begin to experience symptoms until the disease is already at a late stage. In fact, some people may experience no symptoms at all. This is the reason that screening tests, such as a colonoscopy, are so important.

In general, signs and symptoms of colorectal cancer can include the following:

Changes in bowel habits
Blood in the stool
Problems related to blood loss (anemia, weakness, fatigue, shortness of breath, pounding or racing heart, chest pain, and intolerance to exercise)
Abdominal discomfort (frequent gas, bloating, fullness, cramps, and pain)
Unexplained weight loss
Pain with defecation
Stools that are narrower than usual
Urgent desire to defecate (and the passage of little matter)

These symptoms may be caused by colorectal cancer or by other conditions such as infections, hemorrhoids, and inflammatory bowel disease. It is important to bring any of these symptoms to the attention of your health care provider to determine the cause of your symptoms.

Causes

Although more than half of all colorectal cancers occur without any clear cause, studies suggest that genetic factors may play an important role in the development of the disease. For example, many people with colorectal cancer carry specific genetic mutations (genes that normally suppress cancer growth are mutated and actually promote cancer growth) or have relatives with the condition. Those with a family history of specific genetic syndromes -- such as familial adenomatous polyposis, Lynch syndrome, juvenile polyposis, and Peutz-Jeghers syndrome -- are also at an increased risk for developing colorectal cancer. Dietary and lifestyle factors, such as smoking and high-fat intake, also influence the development of colorectal cancer. Some researchers speculate that genetic factors predispose a person to colorectal cancer, but that dietary and lifestyle factors play a strong role in determining which "at-risk" individuals go on to develop the disease.

Risk Factors

Family history of colorectal cancer or polyps in the colon
Older age (over 50 years)
Living in an industrialized country like the United States
Polyps on the inner lining of the colon or rectum
African-American descent
Diets high in meat and low in fruits and vegetables
Overweight or obesity
Regular consumption of alcohol
Smoking cigarettes regularly
Inflammatory bowel disease (such as irritable bowel syndrome, Crohn's disease, and ulcerative colitis)

Diagnosis

After obtaining a complete medical history, a health care provider will perform a physical exam and may order one or more tests to diagnose colorectal cancer. As mentioned in the Preventive Care section, standard tests used to diagnose colorectal cancer include the sigmoidoscopy, colonoscopy, and barium enema. At the time of either a sigmoidoscopy or a colonscopy, a biopsy (sample of tissue) is removed from the colon or rectum and examined under a microscope in order to detect abnormal growths. If the doctor finds cancer, a series of tests (chest x-ray, abdominal CT scan, and blood tests to check liver function) will be performed to determine if the cancer has spread and to help determine the stage (or extent) of the disease. Stages of colorectal cancer include:

Stage A: The earliest stage; cancer is found only in the innermost lining of the colon and/or rectum.
Stage B1: Involves the muscular part of the colon and/or rectum.
Stage B2: Cancer has spread to deeper layers of the wall of the colon and/or rectum.
Stage C: Cancer has spread to nearby lymph nodes but not to other parts of the body.
Stage D: Cancer has spread to other parts of the body, such as the liver and lungs.

Preventive Care

Screening

Colorectal cancer is highly preventable, even curable, when detected early. Regular screening for colorectal cancer helps detect the presence of polyps before they become cancerous. The American Cancer Society recommends the following standard screening practices for individuals who are not at high risk for colorectal cancer and who have no symptoms of the disease:

Annual digital rectal exams starting at age 40: The doctor inserts a lubricated, gloved finger into the rectum to feel for abnormal areas.
Annual fecal occult blood tests starting at age 50: Stool samples are tested in the doctor's office for the presence of hidden blood.
Visualization of the colon via one of the following:
- Sigmoidoscopy (examination of the rectum and lower colon using a lighted instrument)
- Colonoscopy (examination of the rectum and entire colon using a lighted instrument)
- Barium enema (examination using a series of x-rays that reveal barium-stained outlines of the colon and rectum) every 3 -5 years starting at age 50

Those with a family history of colorectal cancer should undergo colonoscopy every 3 - 5 years, starting at least 10 years before the age of the relative at the time of his or her diagnosis. Those with a family history of familial adenomatous polyposis (a condition causing thousands of polyps along the inner lining of the colon) or other similar genetic syndromes (listed under Causes) should start having colonoscopies at age 10.

Diet and Exercise

People may also lower their chances of developing colorectal cancer by managing the risk factors they can control, such as diet and exercise. For example, eating plenty of fruits and vegetables as well as foods rich in omega-3 fatty acids (such as salmon and halibut) and calcium (such as sea vegetables and kale) can help reduce the risk of colorectal cancer. Limiting alcohol consumption, quitting smoking, and reducing the intake of high-fat and fried foods, particularly red meats, may also protect developing colorectal cancer.

Physical activity also will decrease the risk factors associated with developing colorectal cancer. Obesity and a sedentary lifestyle increases the risk of colorectal cancer. Even small amounts of exercise on a regular basis can be helpful, and the American Cancer Society recommends at least 30 minutes of physical activity on most days.

Other Preventive Measures

Preliminary studies also suggest that aspirin may prevent tumor growth and that hormone replacement therapy (HRT) may reduce the risk of colorectal cancer in women. However, HRT may increase the chances of developing other cancers, such as breast and ovarian. It is recommended to choose diet and lifestyle changes along with dietary supplements to protect against the risk factors associated with colorectal cancer.

Treatment

Surgery to remove the tumor is the only way to cure the disease, and early detection is the best preparation for successful treatment. Depending on the stage of the cancer, surgery is generally followed with chemotherapy. If the tumor is particularly large, radiation may be necessary before or after surgery.

Certain medications or supplements may help prevent the development of polyps and/or colorectal cancer. Modifying lifestyle, particularly avoiding red meat, losing weight, quitting smoking, and increasing physical activity, may help prevent the disease -- even in individuals with a family history of the condition.

Lifestyle

An unhealthy lifestyle may increase the risk of colorectal cancer even in people who have no family history of the condition. Some experts believe that adjusting lifestyle habits may decrease the likelihood of developing colorectal cancer by as much as 70% in some individuals.

Findings from studies support the association between colorectal cancer and physical inactivity and obesity. Research continues to point to the idea that exercise and low-calorie diets can help to prevent colorectal cancer.

A large, population-based study of men and women in Hawaii found that the following lifestyle factors were linked with colorectal cancer:

Smoking
Alcohol consumption
History of diabetes
Frequent constipation
High-calorie diet
Obesity
Physical inactivity
Low vegetable fiber intake (this association is controversial)
High levels of insulin (hormone that controls blood sugar levels)
Meat consumption

Medications

After surgery, chemotherapy (the use of anticancer drugs to destroy cancer cells) may be given to kill any cancerous cells that remain in the body. Chemotherapy controls the spread of the disease and improves survival rates over time. The following chemotherapeutic medications are used alone or in combination to treat colorectal cancer:

Fluorouracil (5-FU) -- often used in combination with leucovorin for 6 months after surgery. Reduces the rate of recurrence and improves chances of survival. Common side effects include nausea, diarrhea, inflammation of the skin and lining of the mouth, and lowered white blood cell count, which increases the chance of developing an infection and anemia.
Leucovorin -- a form of folic acid often used in combination with 5-FU. Side effects are rare but can include rash, itching, and wheezing.
Levamisole -- can be used in combination with 5-FU. Potential side effects are numerous and include nausea, vomiting, diarrhea, loss of appetite, abdominal pain, lower extremity swelling, insomnia, fatigue, headache, hair loss, dizziness, muscle and joint paints, and depression.

For colorectal cancer that has metastasized, or spread, doctors generally use 5-FU in combination with other drugs. One regimen approved by the United States Food and Drug Administration for metastatic colorectal cancer is 5-FU, leucovorin, and irinotecan. With the addition of irinotecan, the progression of the disease significantly slowed and survival improved compared to the 5-FU-leucovorin combination. However, an unexpectedly high death rate in two recent studies by the National Cancer Institute has brought the addition of irinotecan into question. There are other medications currently under investigation for metastatic colon cancer.

Long-term use of aspirin, other nonsteroidal anti-inflammatory drugs (NSAIDs), and hormone replacement therapy have shown promise in the prevention and treatment of colorectal cancer.

Aspirin -- may reduce the risk of polyps and colorectal cancer by up to 44%.
NSAIDs -- reduced the number of polyps by 90% and colon tumors by 55% in animals.
Hormone-replacement therapy (HRT) -- over the past 20 years, the rate of death from colorectal cancer among women has decreased far more than the rate among men. Studies suggest that this may be due to the increasing use of hormone-replacement therapy by women after menopause. However, HRT is not without risks, and your health care provider will help you determine which treatment is best for you.

Surgery and Other Procedures

Surgery is the treatment of choice for colorectal cancer, and is best when the disease is detected at an early stage. Before becoming cancerous, polyps can be removed during a colonoscopy. Depending on the severity and location of the cancer, including whether or where it has spread, an individual may need a partial or total removal of the colon (colectomy) and rectum (rectal resection). During surgery, the surgeon also examines other abdominal organs for signs of cancer. If cancer has spread to the liver, a portion of this organ may be removed as well. After removing the tumor and nearby tissue, the surgeon reconnects the healthy portions of the colon or rectum. If the healthy portions of the colon or rectum cannot be reconnected, a temporary or permanent opening (stoma) is made through the wall of the abdomen into the colon to provide a new path for waste material to leave the body. This procedure is called a colostomy. Radiation may also be used before or during surgery (called intraoperative radiotherapy) to shrink the tumor, and it may be recommended following surgery for certain stages of colorectal cancer to reduce the risk of recurrence. Following surgery, colonoscopies are performed every 3 - 6 months for 3 years to detect recurrence.

Nutrition and Dietary Supplements

A comprehensive treatment plan for colorectal cancer may include a range of complementary and alternative therapies. Nutrients and herbs may protect against side effects from conventional therapies as well as enhance chemotherapy and support anticancer activities. Mind-body therapies such as meditation, relaxation techniques, yoga, and qi gong may reduce the effects of stress and enhance your quality of life and your response to treatment. Ask your team of health care providers about the best ways to incorporate these therapies into your overall treatment plan.

Always tell your health care provider about the herbs and supplements you are using or considering, as some supplements may interfere with conventional cancer treatments.

Following these nutritional tips may help reduce symptoms:

Try to eliminate potential food allergens, including dairy, wheat (gluten), corn, preservatives, and food additives. Your health care provider may want to test for food sensitivities.
Eat antioxidant foods, including fruits (such as blueberries, cherries, and tomatoes), and vegetables (such as squash and bell peppers).
Eat foods high in B-vitamins and calcium, such as almonds, beans, whole grains (if no allergy), dark leafy greens (such as spinach and kale), and sea vegetables.
Avoid refined foods such as white breads, pastas, and especially sugar.
Eat fewer red meats and more lean meats, cold-water fish, tofu (soy, if no allergy) or beans for protein. Quality protein sources, such as organic meat and eggs, whey, and vegetable protein shakes, should be used as part of balanced program aimed at gaining muscle mass and preventing wasting that can sometimes be side effects of cancer therapies.
Use healthy oils, such as olive oil or vegetable oil.
Reduce or eliminate trans-fatty acids, found in commercially baked goods such as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
Avoid coffee and other stimulants, alcohol, and tobacco.
Drink 6 - 8 glasses of filtered water daily.
Exercise at least 30 minutes daily, 5 days a week.

You may use nutritional deficiencies with the following supplements:

A multivitamin daily, containing the antioxidant vitamins A, C, E, the B-complex vitamins, and trace minerals such as magnesium, calcium, zinc, and selenium.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 - 3 tablespoonfuls oil daily, to help decrease inflammation and help with immunity. Cold-water fish, such as salmon or halibut, are good sources.
Vitamin C, 500 - 1,000 mg, one to three times daily, as an antioxidant and for immune support.
L-glutamine, 500 - 1,000 mg three times daily, for support of gastrointestinal health and immunity.
Probiotic supplement (containing Lactobacillus acidophilus), 5 - 10 billion CFUs (colony forming units) a day, when needed for maintenance of gastrointestinal and immune health. You should refrigerate your probiotic supplements for best results.
Grapefruit seed extract (Citrus paradisi), 100 mg capsule or 5 - 10 drops (in favorite beverage) three times daily when needed, for antibacterial, antifungal, and antiviral activity, and for immunity.
Astaxanthin, 2 - 6 mg daily, for immune and antioxidant support.
Alpha-lipoic acid, 25 - 50 mg twice daily, for antioxidant support.
Resveratrol (from red wine), 50 - 200 mg daily, to help decrease inflammation and for antioxidant effects.
Coenzyme Q10, 100 - 200 mg at bedtime, for antioxidant and immune activity.
Melatonin, 2 - 6 mg at bedtime as needed, for immune support and sleep. Higher doses may be needed in cancer. Consult your health care provider.

Herbs

Herbs are generally a safe way to strengthen and tone the body's systems. As with any therapy, you should work with your health care provider to get your problem diagnosed before starting any treatment. You may use herbs as dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, you should make teas with 1 tsp. herb per cup of hot water. Steep covered 5 - 10 minutes for leaf or flowers, and 10 - 20 minutes for roots. Drink 2 - 4 cups per day. You may use tinctures alone or in combination as noted.

Green tea (Camellia sinensis) standardized extract, 250 - 500 mg daily, for antioxidant, anticancer and immune effects. Use caffeine-free products. You may also prepare teas from the leaf of this herb.
Reishi mushroom (Ganoderma lucidum) standardized extract, 150 - 300 mg two to three times daily, for anticancer and immune effects. You may also take a tincture of this mushroom extract, 30 - 60 drops two to three times a day.
Maitake mushroom (Grifola frondosa) standardized extract (D-fraction), 600 mg twice daily, for immune and anticancer effects. You may also take a tincture of this mushroom extract, 30 - 60 drops two to three times a day.
Olive leaf (Olea europaea) standardized extract, 250 - 500 mg one to three times daily, for anticancer and immune effects.
Turmeric (Curcuma longa) standardized extract, 300 mg three times a day, for pain and inflammation.
Milk thistle (Silybum marianum) seed standardized extract, 80 - 160 mg two to three times daily, for detoxification support.
Fermented wheat germ extract, 1 packet dissolved in favorite beverage once daily, for anticancer and immune effects.

Acupuncture

While acupuncture is not used as a treatment for cancer itself, evidence suggests it can be a valuable therapy for cancer-related symptoms (particularly nausea and vomiting that often accompanies chemotherapy treatment). Studies have indicatedthat acupuncture may help reduce pain and shortness of breath. Acupressure (pressing on rather than needling acupuncture points) has also proved useful in controlling breathlessness. Patients can learn this technique and use to treat themselves.

Some acupuncturists prefer to work with a patient only after the completion of conventional medical cancer therapy. Others will provide acupuncture or herbal therapy during active chemotherapy or radiation. Acupuncturists treat cancer patients based on an individualized assessment of the excesses and deficiencies of qi located in various meridians. In many cases of cancer-related symptoms, a qi deficiency is usually detected in the spleen or kidney meridians.

Mind-Body Medicine

Relaxation techniques are beneficial for individuals undergoing surgery. In one study it was observed that patients who received standard care plus relaxation techniques in the form of guided imagery audiotapes before, during, and after surgery experienced significantly better sleep and less pain following the surgery than patients who received only standard care.

Other Considerations

Pregnancy

Colorectal cancer may be detected late in pregnant women because symptoms of the disease, such as rectal bleeding, nausea, and vomiting, resemble the symptoms of pregnancy. Pregnant women should avoid chemotherapy and radiation therapy. Surgery puts the fetus at risk, therefore folic acid and nutritional needs are usually maintained during pregnancy, and treatment is postponed until after the baby is delivered.

Prognosis and Complications

Follow-up care after treatment for colorectal cancer is very important. If the cancer returns or if new cancer develops, it should be treated as soon as possible. If left untreated, colorectal cancer can spread to the liver or lungs, or a tumor may block the colon. In some cases, individuals with colorectal cancer may need to have their entire colon or rectum removed. If the surgeon cannot reconnect healthy portions of the colon or rectum, a temporary or permanent surgical opening (stoma) is made through the wall of the abdomen into the colon to provide a new path for waste material to leave the body. After this procedure, a special bag is worn to collect body waste. Individuals who wear the bag may need counseling on how to care for the stoma as well as how to deal with the emotional difficulties associated with this procedure.

The outlook in cases of colorectal cancer depends on how deeply the tumor has penetrated into the tissue and whether the cancer has spread to lymph nodes in the abdominal region or to other areas of the body. Following are the proportions of individuals who survive at least 5 years based on the stage of their disease when it was first diagnosed:

Stage A -- more than 90%
Stages B1 and B2 -- 85%
Stage C -- 70% to 80%
Stage D -- 5%

HEALTH GUIDE REFERENCE FROM A.D.A.M

People who intentionally starve themselves into an emaciated state yet remain convinced that they are overweight are suffering from a condition known as anorexia nervosa. Anorexia is a severe emotional disorder that is increasingly common, especially among young women in industrialized countries where cultural expectations encourage women to be thin. Fueled by popular fixations with thin and lean bodies, anorexia is also affecting a growing number of men, particularly athletes and those in the military. People with anorexia are terrified of becoming obese and refuse to maintain a normal weight, putting themselves in danger of starvation.

Anorexia rarely begins in people who are older than 40 years of age. It most commonly appears in the teenage years, affecting up to 3 in 100 adolescents. Although anorexia seldom emerges before puberty, associated mental conditions, such as depression and obsessive-compulsive behavior, are usually more severe when it does. The onset of anorexia is often preceded by a traumatic or stressful event and it is usually accompanied by other emotional difficulties. Anorexia is a life-threatening condition that can result in death from starvation, heart failure, electrolyte imbalance, or suicide.

There are two main types of anorexia nervosa:

Restricting Type -- characterized by dieting, fasting, or excessive exercise
Binge-Eating/Purging Type (anorexic-bulimic) -- characterized by self-induced vomiting or misuse of laxatives, enemas, or diuretics. Binge eating may or may not occur, and purging (vomiting) is common even after small amounts of food have been eaten. This type carries greater medical risk.

Signs and Symptoms

The primary sign of anorexia nervosa is severe weight loss, accompanied by any number of physical and psychological symptoms and unusual behaviors related to food, eating, or exercise. A person for whom a healthy weight would be 125 pounds, for example, may drop 20, or even as much as 60, pounds below this. At the same time, the person may insist that they are overweight.

Physical Signs

Scanty or absent menstrual periods
Thinning hair
Dry skin
Cold or swollen hands and feet
Bloated or upset stomach

Psychological Signs

Distorted perception of self (that is, a great difference between how an individual believes they look and their actual physical appearance)
Inability to remember things
Poor judgment
Refusal to acknowledge the gravity of the illness
Obsessive-compulsive behavior (excessive need to control personal environment)
Depression (feelings of ineffectiveness, loss of interest in friends and former activities, lack of spontaneity, rigid thinking, lack of initiative, flattened emotional response, irritability, insomnia, and diminished interest in sex)

Behavioral Symptoms

Unusual behaviors related to food or eating (for example, hoarding or concealing food, refusing to eat in public, eating only one type of food, ritually cutting food into tiny pieces, intense study of diets and calories, planning and preparing elaborate meals for others)
Compulsive exercising
Preoccupation with body size or body image
Preoccupation with weight control, dieting

Causes

There is no specific cause of anorexia. Medical experts agree that several factors work together in a complex fashion to lead to the eating disorder. These may include:

Severe trauma or emotional stress (such as the death of a loved one or sexual abuse) during puberty or prepuberty.
Abnormalities in brain chemistry. Changes in serotonin levels, a brain chemical that regulates appetite, may contribute to other symptoms of anorexia nervosa such as depression, impulsiveness, obsessive behaviors, or other mood disorders. In addition, the process of purging may deplete tryptophan, an amino acid necessary for the production of serotonin, leading to further imbalances.
A cultural environment that puts a high value on thin or lean bodies.
Overbearing, controlling, and critical parents who do not show emotional warmth.
A tendency toward perfectionism, fear of being ridiculed or humiliated, a desire to always be perceived as being "good." A belief that being perfect is necessary in order to be loved. Because perfection is impossible, the inability to attain perfection reinforces the person's sense of being unworthy of being loved. Not eating, according to some experts, is a passive act of revenge directed toward those who will never love the person because of his or her lack of perfection.
Family history of anorexia. About one-fifth of those with anorexia have a relative with an eating disorder. In fact, it is common to discover that someone with anorexia has a mother or sister with this eating disorder as well. If one identical twin has anorexia, the other has more than a 50% chance of also developing it. It is not clear, however, to what extent this family connection is due to heredity or to learned behavior.
Infection. Some researchers report an association between beta-hemolytic streptococcal infection, or Epstein Barr virus (the virus that causes mononucleosis), and development of anorexia.

Risk Factors

Age and gender -- anorexia is most common in teens and young adult women.
Early onset of puberty
Living in an industrialized country
Depression -- although depression is associated with the development of anorexia, it does not cause the disorder. Depression in a family member also appears to increase the likelihood of developing an eating disorder.
Obsessive-compulsive disorder (OCD) or other anxiety disorders -- OCD is present in up to two-thirds of people with anorexia. OCD associated with an eating disorder is often accompanied by a compulsive ritual around food (such as cutting it into tiny pieces). Phobia, another type of anxiety disorder that may also be present in someone with an eating disorder, and OCD tend to emerge before the eating disorder, while panic attacks may develop after the diagnosis is made.
Avoidant or narcissistic personality disorders -- approximately one-third of those with the restricting type of anorexia have avoidant personalities, which is characterized by feelings of inadequacy, social inhibition, extreme sensitivity to negative comments or criticism, and avoidance of interpersonal relationships, both at work and on an intimate level. Borderline personality disorder (exceptionally unstable interpersonal relationships, extremely poor self-image, and excessively impulsive behaviors) may be a risk factor as well, but such individuals are more likely to develop bulimia.
Participation in sports and professions that put emphasis on a lean body (such as dance, gymnastics, running, figure skating, horse racing, modeling, wrestling, acting)
Difficulty dealing with stress (pessimism, tendency to worry, refusal to confront difficult or negative issues)
History of sexual abuse or other traumatic event
Dieting

Diagnosis

While your doctor will rely on points discussed in Signs and Symptoms -- such as excessive weight loss, refusal to maintain normal body weight, and distorted self-perception -- the doctor will also ask a series of questions to better determine whether or not anorexia is present. The SCOFF questionnaire, developed in Great Britain, is proving to be a very reliable method for diagnosing anorexia. A "yes" response to at least two of the following questions is a strong indicator of an eating disorder:

S: "Do you feel sick because you feel full?"
C: "Do you lose control over how much you eat?"
O:"Have you lost more than 13 pounds recently?"
F: "Do you believe that you are fat when others say that you are thin?"
F: "Does food and thoughts of food dominate your life?"

If an eating disorder is suspected, the doctor will order several laboratory tests. These serve to determine blood count (to assess for signs of anemia that may be related to lack of iron or vitamin B12), levels of electrolytes (minerals such as potassium, calcium, and magnesium), amylase (serum amylase is elevated when there is frequent vomiting), and protein, and kidney, liver, and thyroid functions. Your doctor may also order an electrocardiogram (which gives a graphic record of the electrical activity of the heart). This may be abnormal if there is a deficiency in an electrolyte or nutrient such as potassium or calcium. If a diagnosis of anorexia is made, the doctor will require frequent office visits to monitor the condition. It is best for a person with anorexia to work with a multidisciplinary team including a doctor, a psychologist or psychiatrist, and a registered dietitian.

Preventive Care

The most effective prevention strategy is the development, from an early age, of healthy eating habits and a strong body image. Cultural values that place a premium on lean or thin bodies need to be questioned. Education about the life-threatening nature of anorexia is also an important part of prevention.

In those who have already been diagnosed and treated for anorexia, avoiding recurrence of the eating disorder is the primary goal.

Family and friends should be urged not to focus on the patient's condition or on issues of food or weight. Mealtimes, for example, should be reserved for social interaction and relaxation, without any discussion of the disease.
Careful and frequent monitoring of weight and other physical signs by the health care provider can reveal signs of a relapse.
Cognitive or other forms of psychotherapy can help the person to develop coping skills and change the unhealthy thought processes that underlie anorexia nervosa.
Family therapy is helpful in addressing underlying contributing factors in the home environment and in enlisting the support and understanding of family members.

Treatment

Anorexia demands a multi-pronged treatment plan that addresses both the physical and psychological aspects of this disorder. Cognitive-behavioral therapy, often in combination with antidepressants, is a very effective therapeutic approach for treatment of eating disorders. Complementary and alternative methods of treatment (such as the use of herbs and mind-body medicine) are valuable adjuncts to usual ways of stimulating appetite, addressing nutritional problems, and helping the patient to develop a healthier body image and to learn to deal more productively with stress.

In general, the most important aspect of treating anorexia is restoring weight and preventing starvation. Hospitalization may be necessary, particularly under the following circumstances:

Continuing weight loss, in spite of outpatient treatment
Body mass index (BMI) -- BMI is a measurement that takes into account a person's height and weight) 30% below normal. The normal range is a BMI of 19 - 24.
Irregular heart rhythm
Severe depression
Suicidal tendencies
Low potassium levels
Low blood pressure

Generally, adequate weight gain (1 - 2 pounds per week) and appropriate changes in behavior require a 10 - 12 week hospital stay. To avoid bloating, abdominal upset, and fluid retention, those who are severely malnourished are started on a diet of 1,500 calories a day, gradually increasing to as much as 3,500 calories. Because anorexia triggers changes in metabolism, high caloric intake may be necessary to stimulate weight gain.

Unfortunately, there is no completely effective treatment for anorexia nervosa, and recovery can take many years. Even after some weight gain, many people with anorexia remain quite thin and risk of relapse is very high. Several social influences may make recovery difficult:

Friends or family who express admiration or envy of the patient's thinness
Dance instructors or athletic coaches who put a premium on having a very lean body
Denial on the part of parents or other family members
A patient's persistent belief that emaciation is not only normal but also attractive and that purging is the only way to avoid becoming overweight

Involving friends, family members, and others in the treatment of the individual, with education for everyone regarding the gravity of the disease, may diminish these influences.

Lifestyle

Treating anorexia nervosa involves major lifestyle changes. The person must not only alter eating habits but also adjust their self perception to no longer hold a distorted body image. The following lifestyle changes may help in this process:

Establishing regular eating habits and a healthy diet
Developing a support system and participating in a support group for help with stress and emotional issues
Cutting back on exercise if obsessive exercise has been part of the disease. Once sufficient weight gain has been established, controlled exercise regimens can be a positive reinforcement for appropriate eating habits and a way to reduce gastrointestinal distress.

Medications

Anorexia nervosa in some ways resembles other major psychiatric disorders, such as depression and obsessive-compulsive disorder, because people with anorexia exhibit some of the symptoms of these disorders (for example obsessive behavior, lack of enjoyment from life, and severely distorted perception of reality, in this case, of the body). This has led to the use of antidepressants for anorexia, particularly selective serotonin reuptake inhibitors (SSRIs), because these drugs are first-line treatments for OCD and depression. Medications, however, may not work alone and should be used in conjunction with a multidisciplinary approach that includes nutritional interventions and psychotherapy.

Serotonin Reuptake Inhibitors

Fluoxetine

Studies suggest that fluoxetine may increase weight and improve mood over several months in people with anorexia nervosa and depression. Similarly positive results were obtained in a preliminary study of anorexics whose body weight had already been partly restored.

Tricyclic Antidepressants

This class of antidepressants, including imipramine and desipramine, tend to be more effective for bulimia than anorexia.

Clomipramine

One study suggests that clomipramine has the potential to stimulate weight gain and improve symptoms of anorexia.

Antihistamines

Cyproheptadine

In one study, using high doses of cyproheptadine hydrochloride, which is thought to stimulate appetite, decreased the number of days necessary to achieve appropriate weight gain and relieved depression in those with restricting type anorexia.

Hormones

Estrogen together with progesterone may help restore normal menstrual cycles. This, however, does not generally have any effect on weight.

Nutrition and Dietary Supplements

Anorexics with low body weight, low BMI, and low serum albumin (the main protein in blood) levels are at increased risk for vitamin and mineral deficiency. Vitamin abnormalities may contribute to cognitive difficulties such as poor judgment or memory loss and other psychiatric conditions. These deficiencies can often be corrected with dietary interventions.

There are natural therapies, including dietary supplements, that may help the general health and well-being of a person struggling with anorexia to become more balanced. Always tell your health care provider about the herbs and supplements you are using or considering using, as some supplements may interfere with conventional treatments.

Following these nutritional tips may help reduce symptoms:

Avoid coffee and other stimulants, alcohol, and tobacco.
Drink 6 - 8 glasses of filtered water daily. However, do not fill up on water only.
Quality protein sources, such as organic meat and eggs, whey, and vegetable protein shakes, should be used as part of balanced program aimed at gaining muscle mass and preventing wasting. Talk with your health care provider about the best way for you to put on weight.
Try to avoid refined sugars, such as candy and soft drinks.

You may address nutritional deficiencies with the following supplements:

A multivitamin daily, containing the antioxidant vitamins A, C, E, the B-vitamins and trace minerals, such as magnesium, calcium, zinc, and selenium.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 tablespoonful oil two to three times daily, to help decrease inflammation and improve immunity. Essential fatty acids play a critical role in brain function and hormone regulation, key health issues in the anorexic individual.
Vitamin C, 500 - 1,000 mg one to three times daily, as an antioxidant and for immune support.
Coenzyme Q10, 100 - 200 mg at bedtime, for antioxidant, immune, and muscular support.
5-hydroxytryptophan (5-HTP), 50 mg two to three times daily, for mood stabilization.
Creatine, 5 - 7 grams daily, when needed for muscle weakness and wasting.
Probiotic supplement (containing Lactobacillus acidophilus), 5 - 10 billion CFUs (colony forming units) a day, for maintenance of gastrointestinal and immune health. You should refrigerate your probiotic supplements for best results.
L-glutamine, 500 - 1,000 mg three times daily, for support of gastrointestinal health and immunity.
Dihydroepiandosterone (DHEA), start at 5 mg three times a day and work up to 100 mg per day for 7 - 12 months for hormonal effects. It is recommended to use DHEA under the supervision of a qualified health care professional. If adverse effects develop, discontinue use.
Melatonin, 2 - 5 mg one hour before bedtime, for sleep and immune protection.

Herbs

Ashwagandha (Withania somniferum) standardized extract, 450 mg one to two times daily, for general health benefits and stress.
Fenugreek (Trigonella foenum-graecum), 250 - 500 mg two to three times daily, for appetite stimulation.
Cayenne pepper (Capsicum annuum) standardized extract, 400 mg three times daily, for digestive stimulation.
Milk thistle (Silybum marianum) seed standardized extract, 80 - 160 mg two to three times daily, for detoxification support.
Fermented wheat germ extract, 1 packet dissolved in favorite beverage once daily, for immune effects and muscle gain.

Massage and Physical Therapy

Massage appears to be a helpful component of treatment for anorexia nervosa. Individuals using massage report lower anxiety levels and improved body image.

Homeopathy

A professional homeopath can provide supportive care to address various aspects of anorexia. Discuss homeopathy and anorexia with your health care provider.

Cognitive behavioral therapy is reported to be one of the most effective therapies for anorexia. It is based on the assumption that anorexia develops in response to life stresses. Treatment is aimed at confronting the individual's fears and avoidance behaviors and cultivating new problem-solving skills. It also aims to increase awareness of negative thought processes and to change them. Cognitive techniques are used to encourage patients to evaluate and challenge their automatic thoughts, examine their underlying assumptions, and replace them with realistic beliefs and actions based on reasonable self-expectations.

Family Therapy

Family therapy is recommended for both children and adults, in addition to individual therapy for the person with anorexia. Parents and other family members often have intense feelings of guilt and anxiety that they need to address. Family therapy is aimed, in part, at helping the parents or partner (in the case of an adult) understand the medical gravity of this illness and the ways in which they may be inadvertently contributing to it.

Hypnosis

Hypnosis has been reported to be successful as part of an integrated treatment program for anorexia nervosa. Hypnosis reportedly strengthens both self-confidence and the ability to cope, which may result in healthier eating, improved body image, and greater self-esteem.

Biofeedback

Studies suggest that biofeedback may be helpful in reducing stress in people with anorexia.

Other Considerations

Pregnancy

Anorexia poses several potential problems for women who are pregnant or wishe to become pregnant:

Difficulty getting pregnant and carrying a pregnancy to term because of higher rates of infertility and spontaneous abortion
Increased risk of low birth weight babies and birth defects
Malnourishment (particularly calcium deficiency) as the fetus grows
Increased risk of medical complications
Increased risk of relapse being triggered from the stress of pregnancy or parenthood

Prognosis and Complications

Medical complications associated with anorexia include:

Irregular heartbeat and heart attack
Anemia, often related to lack of vitamin B12
Low potassium, calcium, magnesium, and phosphate levels (particularly with binge-purge types)
Increased cholesterol
Hormonal changes (can lead to absence of menstrual periods, infertility, bone loss, and stunted growth)
Osteoporosis
Seizures and numbness in hands and feet
Disorganized thinking
Death (suicide is responsible for 50% of fatalities associated with anorexia)

The outlook for individuals with anorexia is variable, with recovery taking between 4 - 7 years. There is also a high chance of disease recurrence even after recovery. Long-term studies show that 50 - 70% of people recover from anorexia nervosa. However, 25% do not fully recover. Many, even after they are considered "cured," continue to exhibit traits of anorexia, such as remaining very thin and striving for perfection.
