I Don't Buy It: Ear Stapling for Weight Loss

FitSugar — Wed, 07 Nov 2007 08:59:53 -0800

I have heard of some crazy approaches to weight loss and this one might just take the cake – ear stapling. A stainless steel staple is placed on the inner cartilage of the ear to constantly stimulate the acupuncture point associated with the stomach. The staple is supposed to decrease hunger as well as cravings. The cost is generally around $60 and you can keep the surgical staples in your ears for months. "Placing the staple" is a little euphemistic since the action is more like a piercing and infection rates can be as high as 20 percent. While acupuncture has been around for centuries (and you don't walk around with a needle in your ear cartilage), the stapling procedure is quite new and many states have no regulations regarding the procedure. Mississippi was the first state to require a practitioner to be licensed to perform the stapling and Ohio now requires it too.

According to the Mayo Clinic, there is no evidence that stapling works. There is no magic pill or magic staple for weight loss. Even proponents of ear stapling admit that to lose weight you need to lead an active lifestyle and actively want to lose weight.

Highlights

Smoking and Your Health

Smoking may worsen knee osteoarthritis in men. A study published in the Annals of Rheumatic Disease found that male smokers have more pain and cartilage loss than men who do not smoke. Previous studies have not found such a link.
Smoking greatly increases the risk of age-related macular degeneration. An Australian study reports that smokers are four times more likely to develop the eye condition than those who have never smoked. Smokers also developed the condition at an earlier age.
Analysis of several studies suggests that smoking cigarettes and, in some cases, cigars or pipes, may reduce the risk of Parkinson's disease. However, smoking causes many other serious health conditions and should not be considered a means for preventing Parkinson's.
A small study suggests that infants who are breastfed just after their mother smokes sleep less than those whose mothers did not smoke.

Smoking Cessation

Certain genes may make it easier for you to quit smoking. Researchers at Duke University have identified more than 200 genes that distinguish those who have successfully kicked the habit. It is the first time such genes have been identified. The findings could lead to new smoking cessation therapies that target a person's specific genetic makeup.

Smoke Free Zones

More and more households in the United States are banning smoking. The U.S. Centers for Disease Control and Prevention (CDC) reports that 75% of households now forbid smoking at any time or place in the home.

Smoking in the Movies

Teens who see actors smoke on screen are more likely to become established smokers, according to an updated study in the Archives of Pediatric Adolescent Medicine. Study authors say the likelihood of smoking increases with exposure to movies that depict such behavior.

Introduction

More than 20% of adults in the United States smoke, according to a 2006 report by the U.S. Centers for Disease Control and Prevention (CDC). More than 80% of them smoke every day. Although smoking had steadily declined among adults in recent years, the trend now appears to have stalled. Between 2004 and 2005, the CDC says there was no observable change in smoking rates among U.S. adults.

The addictive effects of tobacco have been well documented. Tobacco is considered to be a mood and behavior altering substance that is psychoactive and abusable. Tobacco is believed to be as potentially addictive as alcohol, cocaine, and morphine. Tobacco and its various components increase the risk of cancer (especially in the lung, mouth, larynx, esophagus, bladder, kidney, pancreas, and cervix), heart attacks, strokes, and chronic lung disease.

The younger children start smoking, the more likely they will smoke as an adult. Smoking is often immediately addictive. According to the American Cancer Society, the earlier you start smoking, the more likely you are to develop long-term nicotine addiction.

In the past, advertising was responsible for encouraging some teens to smoke. New regulations have made it much more difficult for advertisers to promote smoking to young people. However, scenes that show people smoking are still common in movies and television shows, often in a positive light. This may be a major influence on the attitude toward smoking in children and adolescents. An updated study in the Archives of Pediatric Adolescent Medicine found that adolescents that watch movies that portray smoking are more likely to become established smokers.

To prevent children from smoking, parents should not smoke, and they should tell their child that they disapprove of smoking. Schoolchildren who believed that both their parents strongly disapproved of smoking were less than half as likely to smoke as those kids whose parents did not show as much disapproval towards smoking. Other research has supported these findings.

Children whose parents closely monitor their television and music-listening habits are less likely to drink, use drugs, and smoke cigarettes.

Neglected children, or children with absentee parents, were four times as likely to abuse drugs, drink, and smoke as children living with parents who were regularly present and who offered a structured lifestyle.

In a 2002 study, children who regularly attended religious services were also less likely to smoke.

Doctors can have a major effect on young people. However, in one survey, less than half of teenagers had ever been asked by their doctors if they smoked or were counseled not to smoke, even though most teen smokers said they would admit to it if asked.

More American men smoke than women. The following chart details the rate of current smoking in the United States among adults aged 18 years and over, grouped by age and sex:

Age	Total	Men	Women
18 - 44 years	24.1%	27.1%	21.2%
45 - 64 years	21.9%	25.2%	18.8%
65 years and older	8.6%	8.9%	8.3%

Source: CDC/National Health Interview Survey 2005

While the number of adults over 65 who smoke is lower than those in other age groups, older adults usually have smoked for a long time (about 40 years) and tend to be heavier smokers, according to the American Lung Association. Because of this, older smokers are more likely to have smoking-related illnesses.

Caucasian students (under age 18) are more likely to smoke than Hispanics and African-Americans. In 2005, the rate of smoking was highest among American Indians and Alaskan natives. Hispanics and Asians had the lowest rates.

In general, the rate of smoking is highest in the Midwest and South and lowest in the Northeast and West. Utah has the lowest rate of smoking in the United States.

A major U.S. government study reported that people who have not graduated from high school or received their General Education Development (GED) certificate tend to have higher smoking rates than those who attended college.

Higher rates of cigarette smoking have been reported among adults who have earned a GED and those with a 9 – 11 grade education. The lowest rates are seen among those with advanced college degrees.

People with low self-esteem and adolescents with behavioral problems have a higher risk for smoking. Men and women with mental disorders are 50% more likely to smoke than those without such illness.

For example, depression and schizophrenia are known risk factors for smoking. Both may actually have biologic effects that are responsible for this higher risk.

Smoking is much more common among persons with disabilities than those without emotional, mental, or physical limitations. A 2007 Centers for Disease Control study found that the rate of smoking is nearly 50% higher among persons with disabilities. The CDC survey included those with mental illness and drug and alcohol addictions in the disabled group.

Evidence now strongly supports the idea that genes play a role in a person's dependence on nicotine. Researchers are now targeting specific genes that may be responsible for nicotine dependence. So far, research has been shown that there is a common genetic vulnerability to both nicotine and alcohol dependence.

Some studies suggest that the cheaper it is to buy cigarettes and smoke, the more widespread smoking will be. For example, states that have low taxes on cigarettes have a high proportion of smokers. Making it more expensive to smoke may reduce the number of smokers.

Nicotine Addiction

Nicotine is the chemical in cigarettes that makes them addictive. Higher levels of nicotine in a cigarette can make it harder to quit smoking. A report by the Massachusetts Department of Health found that the amount of nicotine in cigarettes has steadily increased over the last 6 years. Higher nicotine levels were found in all cigarette categories, including “light" brands. Massachusetts is one of several states that require tobacco manufacturers to submit yearly reports regarding cigarettes.

Some researchers feel nicotine is as addictive as heroin. In fact, nicotine has actions similar to heroin and cocaine, and the chemical affects the same area of the brain.

Depending on the amount taken in, nicotine can act as either a stimulant or a sedative. Cigarette smoking has definite immediate positive effects. For example, it can:

Boost mood and relieve minor depression
Suppress little fits of anger
Enhance concentration and short-term memory
Produce a modest sense of well-being

Most smokers have a special fondness for the first cigarette of the day because of the way brain cells respond to the day's first nicotine rush. Nicotine, particularly taken in the first few cigarettes of the day, increases the activity of dopamine, a chemical in the brain that elicits pleasurable sensations, a feeling similar to achieving a reward.

Over the course of a day, however, the nerve cells become desensitized to nicotine. Smoking becomes less pleasurable, and smokers may be likely to increase their intake to get their "reward." A smoker develops tolerance to these effects very quickly and requires increasingly higher levels of nicotine.

A smoker may "forget" their craving for nicotine if a part of the brain called the insula becomes damaged. A 2007 study published in the journal Science found that smokers with brain damage to this area were 136 times more likely to forget their addiction to nicotine. The findings may one day lead to new drugs that better help a person quit.

Smokeless tobacco, also called spit tobacco, includes chewing tobacco (dip and chew), tobacco powder (snuff), as well as flavored tobacco lozenges. These products also contain nicotine. There are two forms of spit tobacco.

These products allow tobacco to be absorbed by the digestive system or through mucous membranes. Smokeless tobacco contains at least 28 cancer-causing substances. Smokeless tobacco is not a safe substitute for smoking cigarettes or cigars. According to the National Institutes of Health, chewing on an average-size piece of chewing tobacco for 30 minutes can deliver as much nicotine as smoking three cigarettes.

Although research is inconsistent, some evidence suggests that smokeless tobacco produces a 50-fold increase in the risk of oral cancer, gingivitis, and tooth loss.

Health Risks

Smoking -- even just a few cigarettes a day -- has been linked to many serious health risks. Some are listed below.

According to the American Lung Association, smoking is directly responsible for about 90% of the deaths due to lung cancer. Smoking is also responsible for the majority of deaths due to chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis.

A study in the July 2006 American Journal of Respiratory and Critical Care Medicine showed that smokers with asthma who give up smoking can improve their lung function in as little as 1 week. The small study involved 21 smokers with asthma. Ten of them quit smoking for 10 weeks, while the others continued to smoke. After just a week, lung function test scores in those who stopped smoking improved considerably. In less than 2 months, lung function scores among those who stopped smoking improved by more than 15%.

Study authors say their findings show that there is a “reversible component to the harmful effects of smoking on the airways in asthma.”

All forms of tobacco raise heart attack risk. Smoking, chewing tobacco, and being exposed to secondhand smoke greatly increase the risk of a heart attack. In some cases, the risk of heart problems in people who smoke or are exposed to smoke may be three times greater, according to a study published in the journal Lancet. However, the study also found that the risk of a heart attack among those who stopped smoking slowly decreased over time.

Smoking has a negative affect on a man's sexuality and fertility. Heavy smoking is frequently cited as a contributory factor in impotence because it decreases the amount of blood flowing into the penis. One study noted that among men with high blood pressure, smoking caused a 26-fold increase in impotence.

Smoking impairs sperm motility, reduces sperm lifespan, and may cause genetic changes that can affect a man's offspring. One 2002 trial found that men or women who smoke have lower success rates with fertility treatments. An earlier study reported that men who smoke also have lower sex drives and less frequent sex.

Studies have linked cigarette smoking to many reproductive problems. Continuing to smoke during pregnancy may also cause health problems in the baby.

Negative effects of smoking on female fertility include:

Greater risk for infertility. Women at greatest risk for fertility problems are those who smoke one or more packs a day and who started smoking before age 18.
Earlier menopause. Women who smoke tend to start menopause at an earlier age than nonsmokers, perhaps because toxins in cigarette smoke damage eggs.
Pregnancy complications. Women who smoke have a greater risk for ectopic pregnancy and miscarriage.

Effects on Unborn Child. Smoking during pregnancy increases the risk for stillbirth, prematurity, and low birth weight in their babies. Women who smoke during pregnancy have lower levels of folate, a B vitamin that is important for preventing birth defects.

Children of mothers who smoke during pregnancy may also be at increased risk for obesity and diabetes.

Some women have particular genes that may make them especially likely to deliver low birth weight infants if they smoke, although newborns of all female smokers have a greater risk for low weight. The good news is that women who quit before becoming pregnant or even during the first trimester reduce the risk for a low birth weight baby to that of women who never smoked.

Women who want to become pregnant should make every attempt to quit and should use smoking cessation aids before they try to conceive. After birth, if new mothers cannot quit, they should at least be sure not to smoke in the same room as their infant.

Smoking and Breastfeeding. Smoking right before breastfeeding may interrupt the child's sleep patterns. A small study found that such infants sleep less than other infants, and that their sleep time dropped significantly as levels of nicotine in breast milk increased.

Smoking has many harmful effects on bones and joints:

Smoking can keep new bone from forming. Women who smoke are at high risk for loss of bone density and osteoporosis.

Postmenopausal women who smoke have a significantly greater risk for hip fracture than those who do not.
Men who smoke may have more severe symptoms of knee arthritis, according to a study published in the Annals of Rheumatic Disease.
Smokers are more apt to develop degenerative disorders and injuries in the spine.
Smokers have more trouble recovering from surgeries, including knee or hip replacements. A 2006 study published in the Journal of Bone & Joint Surgery suggests that smoking delays tendon-bone healing, which may lead to a slower recovery after rotator cuff repair surgery.
Smokers whose jobs involve lifting heavy objects are more likely to develop low back pain than nonsmokers.
Smoking may increase the risk of rheumatoid arthritis in some older women. A 2006 study in Annals of the Rheumatic Diseases showed that smoking nearly doubled the risk of rheumatoid arthritis in postmenopausal women who did not have the most established genetic risk factor for the disease, a genotype called HLA-DRB1 SE.

Smoking may increase the risk of developing diabetes. Researchers involved in the Insulin Resistance Atherosclerosis Study (IRAS) looked at the relationship between smoking and diabetes and found that 25% of smokers who started the trial with normal blood sugar had diabetes 5 years later compared to 14% of nonsmokers. The results were published in Diabetes Care.

A study released in 2006 supports earlier beliefs that smokers have a higher risk of developing glucose intolerance, a condition that precedes diabetes. The study, published in the British Medical Journal, involved 4,572 people. The findings suggest that chemicals in smoke could affect the pancreas. The pancreas is the organ that produces insulin, which helps control blood sugar (glucose) levels.

Smoking increases acid production in the stomach. It also reduces blood flow and production of compounds that protect the stomach lining.

Diverticulitis. One study suggested that smoking was a major risk factor in diverticulitis, a condition in which small bumps develop in the wall of the colon. In addition, smokers were at risk for complications from diverticulitis, including bleeding and abscess. Diverticulitis mostly affects people over age 50.

Inflammatory Bowel Disease. Smoking has mixed effects on inflammatory bowel disease. Inflammatory bowel disease is the collective term for ulcerative colitis and Crohn's disease. Smokers have been shown to have lower than average rates of ulcerative colitis, but higher than average rates of Crohn's disease. Smokers with Crohn's disease who quit are said to have less severe symptoms.

Peptic Ulcers. Results of studies on the effect of smoking on ulcers are mixed. Some evidence suggests that smoking delays the healing of gastric and duodenal ulcers. One study reported that after ulcers healed, about half of smokers relapsed after a year, and that all heavy smokers relapsed after 3 months. Other studies, however, have found no increased risk for ulcers in smokers. Smoking does not appear to increase susceptibility to Helicobacter pylori (H. pylori), the bacteria that causes many peptic ulcers.

Hepatitis and Cirrhosis. Smoking is linked to increased liver scarring (cirrhosis) caused by either excessive drinking or chronic hepatitis B or C viruses.

Cyanide, a chemical found in tobacco smoke, interferes with thyroid hormone production. Smoking triples the risk for developing thyroid disease, particularly hyperthyroidism and hypothyroidism. Women smokers with subclinical hypothyroidism (a symptom-free condition in which the thyroid gland is mildly underactive) have a higher risk for developing full-blown hypothyroidism than their nonsmoking peers. Smoking has also been linked to goiter, a swelling of the thyroid that occurs in people who do not get enough iodine.

Smokers are at increased risk for heart and circulatory problems and delayed wound healing after surgery. In one study, patients who were able to cut down or quit smoking 6 - 8 weeks prior to knee or hip replacement surgery were much less likely to suffer complications.

The following age-related conditions occur at higher rates in smokers than nonsmokers:

Cataracts. Quitting smoking reduces your chances of needing cataract surgery in the future, although not to the level seen with nonsmokers.

Age-related macular degeneration (AMD). AMD is a leading cause of blindness in older people. An Australian study, published in 2007 found that the condition is four times more likely in persons who smoke than those who have never done so. Symptoms of macular degeneration include a loss of central vision, which makes it difficult to read.
Gum disease and tooth loss. A government study found that more than half of the cases of severe gum disease in adults in the United States may be due to cigarette smoking.
Wrinkles. Studies confirm that smokers are nearly five times more likely to develop more and deeper wrinkles as they age compared to nonsmokers.
Baldness and premature gray hair. Certain chemicals in smoke break down in hair cells, which leads to hair damage.
Hearing loss, particularly high-frequency hearing loss. Some experts believe that losing the ability to hear high pitched sound in smokers may be due to a decrease in blood flow to the cochlea, the part of the ear that carries sound to the brain.
Incontinence. One study of 600 women indicated that smokers and former smokers are twice as likely to develop incontinence as women who never smoked.

Secondhand Smoke

Secondhand smoke is produced by a burning cigarette or other tobacco product. An estimated 4 million children a year get sick from being around secondhand smoke. Parental smoking has been shown to affect the lungs of infants as early as the first 2 - 10 weeks of life, and such abnormal lung function could persist throughout life.

Exposure to secondhand smoke in the home increases the risk for asthma and asthma-related emergency room visits in children who have existing asthma.

Parental smoking is believed to increase the risk for lower respiratory tract infections (such as bronchitis or pneumonia) by 50%. Environmental exposure to smoke is thought to be responsible for 150,000 - 300,000 such cases every year.

Smoking Bans

Smoking bans have spread across the country. By October 2007, at least 22 states and the District of Columbia have passed some type of law banning smoking in almost all public places and workplaces, including restaurants and bars. The date an individual state's ban takes effect varies greatly; some do not take effect until 2008 or 2009.

As of January 1, 2006, nine states were considered "smoke-free" -- California, Connecticut, Delaware, Massachusetts, Maine, New York, Rhode Island, Vermont, and Washington.

Quitting Smoking

It's never too late to quit smoking. According to the American Cancer Society, about half of all smokers who keep smoking will die from a smoking-related disease. Quitting has immediate health benefits.


Time after last cigarette	Physical Response
20 minutes	Blood pressure and pulse rates return to normal.
8 hours	Levels of carbon monoxide and oxygen in the blood return to normal.
24 hours	Chance of heart attack begins to decreases.
48 hours	Nerve endings start to regrow. Your ability to taste and smell increases.
72 hours	Bronchial tubes relax and the lungs can fill with more air.
2 weeks to 3 months	Improved circulation; lung function increases up to 30%.
1 to 9 months	Decreased rates of coughing, sinus infection, fatigue, and shortness of breath; regrowth of cilia in the airways, increasing the ability to clear mucus and clean the lungs and reducing the chance of infection; overall energy level increases.
Long-Term Effects	After a year, the risk of dying from heart attack and stroke is reduced by up to 50%.

According to the National Institutes of Health, about 40% of smokers who want to quit make a serious attempt to do so each year, but fewer than 5% actually succeed. A June 2006 report published by the NIH says that the available smoking cessation products and therapies are greatly underused. If more smokers asked for or were offered such help, the agency says quit rates could double or triple.

Some people have certain genes that make quitting easier. Researchers at Duke University have identified more than 200 genes that distinguish those who have successfully kicked the habit. It is the first time such genes have been identified. The findings could lead to new smoking cessation therapies that target a person's specific genetic makeup.

Methods of quitting smoking include counseling and support groups, nicotine patches, gums, lozenges, and sprays, smoking cessation pills, and slowly cutting back on the number of cigarettes smoked (incremental reduction).

About 4% of smokers who quit without any outside help succeed. Nevertheless, most people try to quit alone, and many have reported activities that can help the process of withdrawal. The primary obstacle in trying to quit alone is making the behavioral changes necessary to eliminate the habits associated with smoking. Excellent books, tapes, and manuals are available and are strongly recommended to help people who want to quit without other assistance.

Nicotine replacement therapy involves the use of products that provide low doses of nicotine that do not contain the contaminant found in smoke. The goal of therapy is to relieve cravings for nicotine and ease the symptoms of withdrawal.

In general, nicotine replacement therapy benefits moderate-to-heavy smokers the most. However, it does appear somewhat helpful for light smokers (people who smoke fewer than 15 cigarettes a day).

Nicotine Patches. Nicotine patches deliver nicotine through the skin. This is called transdermal nicotine delivery. It is effective in reducing symptoms during withdrawal. Nicotine patches are available over the counter.

Patches may work in different ways:

Step-Down Approach. Patches that use this method include NicoDerm CQ. The patches come in three strengths (21, 14, and 7 mg). You use the strongest dose first and reduce it gradually over a period of 8 - 10 weeks. A 21 mg patch is about equal to 15 cigarettes. A heavy smoker may need to wear two patches at first.
Single-Step Approach. The single-step patch (Nicotrol) can be taken off after 16 hours and replaced 8 hours later. It can be used for only 6 weeks.

Patches are applied and used in similar ways:

A single patch is worn each day and replaced after 24 hours.
To avoid skin irritation it is applied to different hairless locations above the waist and below the neck each day.
People can wear the patches for 24 hours, but some have reported odd dreams and have disliked the sensation of the patch during the night. People who wear the patch all the time, however, have fewer withdrawal symptoms and slightly better abstinence rates than those who take it off at night.
Patches should be stored and discarded safely, particularly in homes with small children. Small children have been poisoned and gotten sick from wearing, chewing, or sucking on nicotine patches. There have been no reports of death from children who have been poisoned.
The FDA recommends using the patches for 3 - 5 months, although some studies suggest that using them for 8 weeks achieves the maximum benefits.

Children should not come in contact with the patches, even while the smoker is wearing them. If the child has worn the patch, the affected skin should be washed right away. Urgent medical care may be required if the child has eaten nicotine or worn a patch for a prolonged time.

Nicotine Gum. Nicotine gum (Nicorette) is available over the counter and has helped many people quit. Some prefer it to the patch because they can control the nicotine dosage, and chewing satisfies the oral urge associated with smoking.

Tips for using the gum:

If you are just starting to quit, chew 1 - 2 pieces each hour. A smoker should not chew more than 20 pieces a day.
The goal is to stop using the gum by 6 months, but about 3% of people continue to use it long after they have quit smoking.
The gum must be chewed slowly until it develops a peppery taste. It is then tucked between the gum and cheek where it is stored so that the nicotine can be absorbed.
Coffee, tea, soft drinks, and acidic beverages may interfere with nicotine absorption, so people should wait at least 15 minutes after drinking before chewing a piece of gum.

Some people prefer other methods or cannot use the gum for the following reasons:

They find the gum unpleasant tasting.
Side effects specific to the gum may include upset stomach, mouth ulcers, hiccups, and throat irritation.
They are embarrassed by chewing gum.
They wear dentures.

Long-term dependence may be a problem with the gum. Although such dependence is probably safer than smoking, research is needed to confirm this, and experts recommend people chew gum for no more than 6 months.

The Nicotine Inhaler. The nicotine inhaler resembles a plastic cigarette holder. It comes with a number of nicotine cartridges, which are inserted into the inhaler and "puffed" for about 20 minutes, up to 16 times a day. The dose is gradually decreased. It requires a prescription in the United States. Several studies have reported that the inhaler triples abstinence rates (between 17 - 28%) compared with placebo (6 - 9%) after 6 months. It has some specific advantages over other nicotine replacement products:

The inhaler provides varying doses of nicotine on demand (as opposed to continuously with the patch or the gum) and is relatively fast-acting. Blood nicotine levels peak about 20 minutes after using the inhaler, comparable to the gum and faster than the 2 - 4 hours seen with the patch.
It satisfies oral urges.
Most of the nicotine vapor is delivered in the mouth, not into the lung airways (although some people experience mouth or throat irritation and cough).

Using a combination of the inhaler and the patch may be particularly effective. In one study, the combination led to an abstinence rate of over 60% after 6 weeks. While this percentage dropped off over time, it was still a large improvement over the use of the inhaler and a placebo patch.

The Nicotine Nasal Spray. The nasal spray satisfies immediate cravings by providing doses of nicotine rapidly and thus may play a useful role in conjunction with slower-acting nicotine replacement therapies. (Nicotine levels peak within 5 - 10 minutes after administering the spray). The spray can irritate the nose, eyes, and throat, so it may not be suitable for those with allergies or sinus infections. Most people, however, can tolerate the side effects, which usually go away within the first few days.

Nicotine Lozenge. A nicotine lozenge (Commit) is available over the counter. It is made from pressed tobacco and comes in two strengths for heavier or lighter smokers. In a large 2002 study, 15 - 18% of smokers who used it remained smoke free, compared to 6 - 10% who were given a dummy lozenge. Side effects included heartburn, hiccups, nausea, headaches, and cough. The Commit lozenge also contains phenylalanine, a chemical that certain people may need to avoid.

Facts about Nicotine Replacement Therapy:

Not cheating on the very first day of nicotine-replacement use increases the chance of quitting permanently by tenfold.
The more cigarettes a patient smokes, the higher the dose of nicotine replacement may be required at the start.
Adding a counseling program may boost the effect of any nicotine replacement program.
Do not smoke while using nicotine replacement. It can cause nicotine to build up to toxic levels.
Nicotine replacement helps prevent weight gain while it is being used, but people are still at higher risk for gaining weight when they stop all nicotine.

Side Effects. Side effects of any nicotine replacement product may include headaches, nausea, and other gastrointestinal problems. People often experience sleeplessness in the first few days, particularly with the patch, but the insomnia usually passes. Patients using very high doses are more likely to have symptoms. Reducing the dose can prevent them.

Special Concerns for Specific Individuals. There has been some concern that the patch might be harmful for people with heart or circulatory disease, but studies are finding that it poses no danger for these individuals. In fact, it may help reduce angina attacks brought on by exercise. However, unhealthy cholesterol levels (lower HDL levels) caused by smoking remain abnormal with use of the nicotine patch. HDL levels improve when all nicotine is stopped.

Nicotine replacement may not be completely safe in pregnant women, although it has been used successfully in this group without ill effect. There is an increase in heart rates in unborn children of women who use the patch as compared with those who smoke.

Keep all nicotine products away from children. Nicotine is a poison. All nicotine products should be kept safely away from small children. A parent should call a physician or a poison control center immediately if a child has been exposed to a nicotine replacement product, even for a short duration. Parents should also call the doctor if a small child has been exposed to a nicotine product and has any symptoms, including stomach upset, irritability, headaches, a rash, or fatigue.

Warnings Against Long-Term Use. No one should use nicotine replacement therapies as a long-term substitute for smoking. Any nicotine replacement therapy should be temporary. In one study, use of nicotine gum for more than a year was associated with insulin resistance, an abnormality that occurs in diabetes. Some studies have now suggested that nicotine itself may have properties that increase the risk for cancer, independent of carcinogenic chemicals in smoke. More studies are needed.

Bupropion (Zyban, Wellbutrin) is a type of antidepressant that is also an FDA-approved product for smoking cessation. It differs from most other antidepressants because it increases the effects of dopamine, the brain chemical that appears to play a strong role in nicotine addiction. Using Zyban along with nicotine replacement therapy may help you better control cigarette smoking cravings. Zyban does not contain nicotine. In most cases, Zyban is taken a week or two before quitting, and must be taken for 7 - 12 weeks. The usual maintenance dose is 150 mg tablet twice a day. No single dose should be higher than 150 mg.

Side effects of bupropion include gastrointestinal problems, headaches, insomnia, dry mouth, and irritation. In very rare cases, seizures have occurred, although usually in people who exceeded the recommended dose or who already had risk factors for seizures.

A newer drug called varenicline (Chantrix) may significantly reduce cigarette cravings and work better than Zyban. A study in the Archives of Internal Medicine found that almost 50% of those who took varenicline successfully quit. Varenicline mimics some effects of nicotine on the brain, but blocks others. Previous studies published in the Journal of the American Medical Association showed that Chantrix works twice as well as Zyban and quadruples one’s chances of successfully quitting. The FDA approved Chantrix as a smoking cessation aid in May 2006. It is for use in cigarette smokers age 18 and older. It should not be combined with nicotine replacement therapy.

The tricyclic antidepressant nortriptyline (Pamelor, Aventyl) may help reduce nicotine action. Quit rates with either of these medicines are as high as 30%. Long-term abstinent rates are more than twice those of placebo. Most other antidepressants, including fluoxetine (Prozac), have no additional benefits for smokers.

Nortriptyline has been specifically studied for helping smokers. It is best to start taking the medication 10 - 28 days before your intended quit date. Studies have reported quit rates of 14 - 24%. Side effects of nortriptyline include dry mouth and changes in taste. It should be noted that in rare cases, tricyclics can have serious side effects, and overdose can be deadly. Tricyclics may pose a danger for some patients with certain types of heart disease.

Smokers who use outside help have the best record for quitting, with success rates of 25 - 35%. Those who are counseled in addition to using nicotine replacement and Zyban have the best chance. Brochures, audio tapes, and other self-help materials are often ineffective when used alone, but may be helpful in conjunction with a counseling program.

Types of behavioral approaches:

Problem Solving or Coping Strategies. Smokers more likely to quit smoking when they learn thinking (cognitive) and behavioral techniques for breaking the link between certain cues and smoking, stress management techniques, and ways to handle the symptoms of withdrawal and the urge to relapse. The more intense the counseling program, the better. Smokers should look for programs that offer the following:

Session lengths of 20 - 30 minutes
Four to seven sessions
A 2-week program
Additional 2 weeks or more of follow-up contact

Scheduled Reduction. Scheduled reduction is a gradual way to stop smoking.

Divide the number of minutes per day that you are awake by the number of daily cigarettes you smoke. The number you get is how long you wait between smokes.
Week 1: Set up a schedule with time intervals based on this result and using a timer, smoke only at those intervals. If the "cigarette appointment" is missed by more than 5 minutes, you must skip that cigarette.
Week 2: Reduce the number of cigarettes you smoke by one-third and recalculate your time between smokes based on the lower number.
Week 3: Reduce the count again.
Week 4: Quit smoking

Those who are unable to smoke during working hours could try calculating the intervals based on the usual smoking times of the day.

The Staged Approach. The intent of the staged approach is to plan quitting interventions customized for each individual rather than imposing some general method for quitting. The approach takes the smoker through six stages with behavioral interventions at each point:

Pre-contemplation
Contemplation
Preparation
Action
Maintenance
Termination

Although some studies report this approach is significantly more effective than non-staged methods, an analysis of 23 trials did not find the staged approach to be any more effective than other methods. Most studies, however, were weak, and better research is needed on this approach.

People who follow this approach do not proceed from one stage to another in a simple, step-by-step fashion. They actually cycle or spiral back and forth, so that they may move from stage 1 to 2 to 3, and then back to 2 again. They may stay in maintenance mode for years and then fall back to stage 2. Remember that this is normal -- if you tried quitting in the past and didn't stick with it, don't consider yourself a failure. Just try again.

Stage 1: Pre-Contemplation.

People at this stage have no plans or desire to stop smoking. They aren't even considering quitting. People at this stage are generally unaware of the specific benefits that quitting can bring. Or, they may simply have "failed" in the past and have given up. There's no point in talking about how to start a cessation program at this stage. Instead, it is important to think about how quitting will help you feel better, have more confidence, or live longer. The benefits must be identified before a person will consider quitting. If you are at this stage, a good activity is to ask several friends or family members why they quit.

Stage 2: Contemplation.

A person at this stage is thinking, "I think I should probably quit, but I need help getting started." People at this stage know that quitting is good for them, but it seems like a daunting task or they don't think they can pull it off. Some may have tried and failed in the past. It's important for people at this stage to consider some of the truths and falsehoods of quitting. If you are at this stage, write down (brainstorm) all your potential roadblocks -- the things that you believe make quitting difficult -- and learn strategies for overcoming or side-stepping those hurdles. People at this stage might benefit from making a pledge, contract, or other commitment that they are going to get more active in the near future. The goal is to identify the roadblocks and ways to overcome these hurdles, and make a commitment to quitting.

Stage 3: Preparation.

Smokers at this stage are ready to quit. The goal of this stage is to create a specific action plan that takes all factors into account, so that quitting is successful. People at this stage need to know what methods work and what support exists to help them. If you are at this stage, you should consider some backup plans -- what to do when the urge to smoke hits you.

Stage 4: Action!

People at this stage have just quit. This stage is where the most behavioral change occurs. It requires significant commitment and energy. If you are at this stage, keep talking to friends and family for inspiration. Review your backup plans. Reward yourself for small achievements. Having a fellow smoker quit with you can be a huge support as you both get through this stage.

Stage 5: Maintenance.

People at this stage have been smoke-free at least 6 months. The goal now is to prevent relapse. If you are at this stage, continue to be wary of roadblocks and keep reminding yourself of the benefits you have gained. Think about what you have found most enjoyable about being smoke-free.

Hypnosis. Although rigorous studies are lacking, some people report successful cessation from smoking when hypnosis is given in individual sessions. The process is effective only if you trust the therapist and can feel completely at ease in the vulnerable and passive state necessary for hypnotic suggestion.

During a typical session, the hypnotherapist will use various techniques (such as imagery, silent counting) to put you in a relaxed state.

When you are very relaxed, but not asleep, the hypnotherapist quietly suggests motivations for not smoking. The hypnotherapist should also reinforce a positive self-image while you are in deep relaxation. This helps many people avoid the depression that accompanies withdrawal.

The sessions usually takes about 1 hour.

You should be taught methods of self-hypnosis to use at home, and follow-up once to reinforce what you've learned.

Acupuncture and Acupressure. The acupuncture technique for quitting smoking usually uses very tiny curved staples inserted into three different points around the edge of the ear. The procedure is painless. You will be told to press each staple in a certain order for a few seconds whenever the craving for a cigarette occurs. The acupuncturist may also use acupuncture points elsewhere on the body. There are no side effects except for some soreness if the acupuncture staple is pressed too hard.

A related technique called acupressure involves simply pressing select points on the body when a craving hits. Some studies have reported good quit rates with acupuncture, but few rigorous studies have been conducted using this approach.

Aim to Quit Completely

Everyone who quits should aim to quit completely. Most people who return to smoking "cheat" in the first few weeks. Quitting completely is essential to regain good health and reverse bad effects caused by smoking. Reducing smoking, even by half, does not eliminate the risk for cancer and other health problems. Although smokers take in less smoke and nicotine, the body is still unable to heal itself from the ongoing intake of toxins. It should also be noted that changing to low-tar cigarettes is not a solution. In fact, smokers of these cigarettes tend to inhale deeper, perhaps even increasing health risks.

Create a List

Write down 10 reasons to quit. In addition to health reasons, the list might include having better smelling hair, clothes, and breath; having fewer wrinkles; enjoying the taste of food; and saving money. Read the list often during the quitting process to help stay motivated.

Decide on a Specific Quit Date

Some people find it helpful to choose a particular date to quit when little or no stress is anticipated for at least the first 3 days. Women affected by PMS should avoid quitting right before their menstrual cycle. It may help to write out a quit contract, putting the date on paper, and getting a friend to sign it. Discard all smoking paraphernalia on the eve before the quit date, and make plans to stay busy on the day itself, and especially at night, when the urge to smoke will be high.

Make an Oath

Take an extreme oath. For example, "If I smoke one more cigarette my dog will die." Although this seems absurd, some people, even well-educated individuals, who have failed all other methods have reported that they quit completely and successfully after taking such an oath.

Let the Body and Mind Heal During Withdrawal

Retreat from the world when cravings become overwhelming. Take naps, warm baths or showers, meditate, or read novels.
Help your body get rid of nicotine. Drink plenty of water, eat fresh fruits, vegetables, whole grains, and fiber-rich foods. Carrots, apples, and celery are good munching foods.
When cravings occur, hold your breath as long as possible or take a few deep rhythmic breaths.
Use meditation or relaxation and deep breathing exercises. In fact, taking deep breaths when the urge to smoke occurs is a good stopgap measure.

Get Family and Friends Involved

Tell all your friends and family that you've already quit, so you'll be embarrassed if they catch you smoking.
Pay a family member or friend if they catch you smoking. The amount should be large enough ($5 - 20) to be a deterrent, but not so large as to be ridiculous.
If your partner or friend smokes, try persuading them to quit or, at the very least, not to smoke around you and others.

Exercise

Studies continue to show that smokers who exercise can greatly increase their ability to quit smoking while reducing their risk for weight gain. Move the muscles when cravings occur. Dance, run, walk, jump up and down, stretch, do push-ups. Yoga is an excellent exercise program for quitting. Older people and anyone with health problems should consult their health care provider before starting such a program.

Maintain a Healthy Diet

Eat plenty of fresh, crunchy fruits and vegetables. This is also a useful way of satisfying oral cravings without adding many calories.
Drink plenty of water and healthy beverages.
Moderate intake of coffee or tea may be helpful. A small study suggested that drinking caffeinated beverages (such as coffee or tea) while on nicotine replacement may enhance energy expenditure and may help prevent weight gain. Moderate coffee intake may also have antidepressant properties. Avoid caffeine in the evening, however, since sleep disturbances can be a problem during withdrawal.

Change Daily Habits

Change your daily schedule, particularly eating times, as much as possible. Eat at different times or eat many small meals instead of three large ones. Sit in a different chair or even a different room.
If you smoke after eating, find other ways to end a meal. Play a tape or CD, eat a piece of fruit, get up and make a phone call, or take a walk (a good distraction that burns calories as well). For example, if you normally have a cigarette with coffee, drink tea instead or use a different cup.
Substitute oral habits by eating celery, chewing sugarless gum, sucking on a cinnamon stick, or carrying worry beads.
Go to public places and restaurants where smoking is prohibited or restricted.
Set short-term quitting goals and reward yourself when they are met.
Every day put the money normally spent on cigarettes in a jar and buy something pleasurable at the end of a predetermined period of time.
Find activities that focus the hands and mind but are not taxing or fattening: Computer games, solitaire, knitting, sewing, whittling, and crossword puzzles.

Denormalization is the idea that smoking is no longer normal. This concept of denormalization is best instituted by laws and local regulations making smoking inaccessible in public places, raising prices, and putting stricter limitations on cigarette advertising.

Increasing taxes on cigarettes may be one of the most important methods for reducing smoking in the population, particularly in younger people.

Evidence is suggesting that banning smoking in work and public places may be leading to a higher quit rate than in places where smoking is permitted.

Denormalization can also work on a personal level. A British study showed that when one spouse makes healthy changes, including quitting smoking, the other one follows. In couples where smoking continues, it usually continues in both.

Symptoms of Withdrawal

After you quit smoking, you with have some withdrawal symptoms. Such symptoms generally peak in intensity 3 -5 days after you quit, and usually disappear after 2 weeks, although some may persist for several months.

The symptoms of withdrawal include both physical and mental difficulties.

Physical Symptoms.

Tingling in the hands and feet
Sweating
Intestinal disorders (cramps, nausea)
Headaches
Sore throat, coughing, and signs of a cold

Withdrawal symptoms should be treated accordingly, just as you would with physical symptoms due to an illness or disease.

Mental and Emotional Symptoms. Tension and craving build up during periods of withdrawal, sometimes to a nearly intolerable point. Nearly every moderate-to-heavy smoker experiences more than one of the following strong emotional and mental responses to withdrawal:

Temper tantrums, intense needs, feelings of dependency, and a state of near paralysis
Insomnia
Mental confusion, vagueness, or difficulty concentrating
Irritability, restlessness, impatience, or anger
Anxiety
Depression

The first signs of nicotine withdrawal seem to appear within 30 minutes of a smoker’s last cigarette. The findings, published in Psychopharmacology, are believed to be the first to show just how early nicotine withdrawal occurs. The study involved 50 people who smoked a pack of cigarettes daily. Half refrained from smoking for 4 hours, while the others smoked as usual. After 30 minutes, those who did not have a cigarette craved one and did more poorly on tasks requiring attention than those in the smoking group. Within 3 hours, the non-smoking group showed increases in anxiety, sadness, and difficulty concentrating.

Depression is common during withdrawal and over the long term. In the short term, it may mimic the feelings of grief felt when a loved one is lost. A smoker should plan on a period of actual mourning in order to get through the early withdrawal depression.

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 have a very low level of success. Only about 6% remain smoke-free after a year. There are strong reasons for this:

Smoking may be masking depression, which can become severe even after the early stages of withdrawal have passed.
For some smokers, the future physical damage incurred by smoking is an abstraction, which fails to motivate quitting when measured up against the very real emotional pain triggered by nicotine withdrawal.
Not only does the smoker suffer, but the negative emotions often harm relationships with friends and family, who might even urge the ex-smoker to take up cigarettes again.

People who suffer from depression while quitting might do better using a combination of emotionally supportive therapy (as opposed to behavioral therapy), nicotine replacements, and antidepressants, such as bupropion (Zyban). If severe depression lasts beyond the withdrawal period, professional help should be sought as soon as possible.

Quitting smoking does increase the risk for weight gain. But, kicking the habit of smoking may cause more weight gain than previously thought. A study in Health Services Research found that the average weight gain among former smokers was about 21 pounds, rather than the 5 - 15 pounds commonly cited. But, fear of weight gain shouldn’t stop a person from quitting smoking. Instead, the study authors encourage weight-control measures after quitting. To come up with a new average, the scientists re-analyzed data from the 1998 Lung Health Study of 5,887 American smokers. That study found that those who quit smoking gained about 12 pounds.

Smoking uses up calories -- about 200 a day according to one study. Burning calories helps you lose weight. After quitting, the body's metabolism slows down, and food is digested better. Insulin levels increase, enabling the body to process more sugar for energy. When you quit smoking, you may snack more frequently.

How to Keep the Weight Off After Smoking. Exercise is very helpful in controlling weight. To burn the same amount of calories as you did while smoking, you need only take an extra 15-minute daily walk and eliminate 100 calories a day from meals. Just a moderate increase in physical activity can help keep weight gain to a minimum.

Nicotine replacement therapy can help protect against weight gain. See the section on "Quitting Smoking" in this report.

Failure to Quit

Biologic, psychological, behavioral, and cultural factors all play a role in nicotine addiction, making smoking one of the hardest addictions to beat. About half of people who quit return to smoking. Even after years of not smoking, some ex-smokers still have occasional cravings for cigarettes.

Some experts suggest that, in addition to depression, there are three major areas responsible for the inability to quit:

Mental performance. Nicotine improves concentration and thinking. Quitting smoking temporarily impairs one's mental performance.
Stress. Although smoking many not reduce stress, stopping certainly increases it.
Weight gain. Quitting smoking can cause you to gain weight. Studies are mixed on whether weight gain is permanent in most smokers or not. Certainly, it is a major factor in relapse. [See "Weight Gain" section in this report.]

How well a person does in the first 2 weeks is critical to their success. Smokers should not be shy about seeking all the help they can during this period. Although withdrawal symptoms can be intense, treatments are available to reduce them.

Attempts to quit are never a waste of time, since the amount of smoking is reduced during these periods. People who keep trying still have a 50 - 50 chance of finally quitting.

Researchers have been trying to discover individual risk factors or sets of behaviors that can help predict why specific people fail to quit. Some factors include:

Being female
Being a heavy smoker
Inhaling deeply
Being a long-term smoker
Having severe withdrawal symptoms

Among many studies, however, only one found a single consistent factor for failure to quit:

Cheating during the first 2 weeks of withdrawal, even with the patch, nearly guarantees that a person will smoke again in 6 months.

Studies show that women have a harder time trying to quit smoking and have less success with abstinence programs than men. There are many proposed reasons for this:

Nicotine has different effects on mood in women compared to men. Women who quit may have greater anxiety and stress than men who quit.
Women are not as physically dependent on nicotine as men, but they are more addicted to the actual behavior of smoking, which is the more powerful deterrent to quitting. This may be the reason why nicotine replacement, which only reduces cravings, tends not to be as effective in women.
Women may fear weight gain after quitting more than men.
Certain phases in the menstrual cycle may reduce the response to drugs that are used to help women quit smoking.
Men may be less supportive than women in helping their partners to quit.
Women trying to quit may miss the feeling of control associated with smoking more than men.

On the positive side, evidence suggests that when women quit, their lung function seems to improve more rapidly than in men who quit.

Lifestyle Changes

Smokers and former smokers should immediately begin to implement a healthier lifestyle and change any other behaviors that might be damaging their health.

Everyone should also maintain a healthy diet, with foods rich in whole grains and fruits and vegetables (particularly dark colored ones). Avoid saturated fats and instead choose monounsaturated fats, which are found in olive oil or fats from oily fish. Two studies have indicated that eating fish more than twice a week might help limit the tobacco damage in people who do not smoke more than a pack and a half a day.

Even with a healthful diet, however, smoking reduces the levels of a number of vitamins, importantly vitamin C. Some research suggests that supplementation of folic acid, a B vitamin, and the antioxidants vitamins E and C and selenium may improve lung function or reduce the damage done by cigarette smoke. Studies have shown that daily vitamin E supplements are associated with reduced risk for prostate cancer among smokers and that higher levels of vitamin E are linked to a lower risk for lung cancer. The best way of achieving healthy levels of important nutrients is from healthy foods.

Women who are pregnant and continue to smoke must be sure to take appropriate vitamins, particularly folic acid. In this way, they might reduce the increased risk of fetal injury and death, although they do not eliminate that risk.

Regular exercise reduces a smoker's risk of heart disease (although still not to the level of a nonsmoker). Exercise does not lower a smoker's risk for lung cancer or emphysema.

If you smoke, you should be screened for any smoking-related disorders. Have your cholesterol and blood pressure checked regularly. Women should have annual Pap smears to detect cervical cancer. All older adults should be screened for colon cancer. Computed tomography (CT) screening programs, which are becoming increasingly available, may detect lung cancer at an early stage. Ask your health care provider if you should have this test, and if your insurance will cover it.

Definition

Magnetic resonance angiography is an MRI exam of the blood vessels. Unlike traditional angiography that involves placing a tube (catheter) into the body, MRA is considered non-invasive.

Alternative Names

MRA; Angiography - magnetic resonance

How the test is performed

You will lie down on a narrow table, which slides into a large tunnel-like tube inside the MRI scanner. You must lie very still during the exam because movement can make the images blurry.

The MRI uses very powerful magnets and radio waves to create clear, detailed pictures of the body. Because of the strong magnets, metal objects must stay outside the room.

A complete scan may take 1 hour or more. In some cases, a dye (contrast medium) is needed to make blood vessels show up better during the MRI. The contrast medium will be given through a needle (IV) placed in your arm.

How to prepare for the test

Most places require you to wear a medical gown. You must remove all jewelry and all other metal objects, including watches, and leave them outside the exam room.

Make sure you tell the radiologist if you have any of the following:

Metal screws, pins, plates, or staples in your body
Heart pacemaker
Intrauterine device (IUD)
Any type of metal implant in the ear or eye
Bullet fragments in the body
Implanted neurostimulator
Insulin or chemotherapy port

If you are pregnant, be sure to tell your doctor and radiologist before having this test.

How the test will feel

The exam is not painful. Some people may feel some pain when the IV is placed into the arm. In addition, some people may have anxiety because the scanner is very close to the body. If you are claustrophobic, tell your health care provider. You may be given a mild sedative.

The table may be hard or cold. You may wish to ask for a blanket or pillow.

The machine produces loud thumping and humming noises. Ear plugs are usually given to reduce the noise.

Why the test is performed

Magnetic resonance angiography (MRA) is a less-invasive alternative to traditional arteriography (angiography), which uses x-rays.

MRA is used to look at the blood vessels in all parts of the body, including the head, heart, abdomen, lungs, kidneys, and legs.

It may be used to diagnose or evaluate conditions such as:

Arterial aneurysm
Aortic coarctation
Aortic dissection
Stroke
Blood vessel diseases
Heart disorders
Atherosclerosis
Kidney disease
Renal artery stenosis (narrowing of the blood vessels in the kidneys)

Normal Values

A normal result shows normal blood vessels without any signs of narrowing or blockage.

What abnormal results mean

An abnormal exam shows a problem with one or more blood vessels. This may suggest atherosclerosis, trauma, a congenital disease, or other vascular condition.

What the risks are

MR angiography is generally safe. However, people have been harmed in MRI machines when metal was in their body or a metal object was in the room. It is very important to tell your health care provider of any metal implants and to always remove all metal from your body and clothing before the test.

FDA Issues Labeling Changes for Drugs That Boost Red Blood Cells

In November 2007, the U.S. Food and Drug Administration (FDA) made several changes to the prescribing labels for erythropoiesis-stimulating drugs. These drugs -- epoietin alfa (Epogen, Procrit) and darbepoetin alfa (Aranesp) -- increase the production of red blood cells. They are used to treat anemia associated with chronic kidney failure, cancer chemotherapy, and antiretroviral HIV therapy.

The new labels have stronger warnings and updated dosing-related safety information. The FDA advises:

For cancer, erythropoiesis-stimulating drugs are used only to treat anemia associated with chemotherapy. Dosing should increase hemoglobin levels to no more than 12 g/dL. These drugs can shorten survival time and increase tumor growth when hemoglobin levels are raised beyond this point. Treatment should stop as soon as chemotherapy is completed. Erythropoiesis-stimulating drugs are not safe or appropriate for all patients undergoing chemotherapy. Patients should discuss the risks and benefits with their oncologists.
For chronic kidney failure, erythropoiesis-stimulating drugs should be used to maintain a hemoglobin level between 10 - 12 g/dL. Higher hemoglobin levels increase the risk for stroke, heart attack, heart failure, or death.
Erythropoiesis-stimulating drugs are used to increase red blood cell numbers and reduce the need for blood transfusions. They do not help improve anemia symptoms, fatigue, or quality of life for patients with cancer or HIV.
Patients who take these drugs should contact their doctors if they experience symptoms such as leg pain or swelling, increased shortness of breath, increased blood pressure, dizziness, or extreme fatigue.

Introduction

Anemia is an abnormal reduction in red blood cells.

This photmicrograph shows normal red blood cells (RBCs) as seen in the microscope after staining.

Anemia is a global problem, at its worst in developing countries. But it is by no means absent in industrialized nations. An estimated 3.4 million Americans suffer from anemia. Anemia is not a single disease but a condition, like fever, with many possible causes and many forms. Causes of anemia include nutritional deficiencies, inherited genetic defects, medication-related side effects, and chronic disease. It can also occur because of blood loss from injury or internal bleeding, the destruction of red blood cells, or insufficient red blood cell production. The condition may be temporary or long-term, and can manifest in mild or severe forms.

As it is impossible to discuss all types of anemia, this report focuses on three of the most common forms:

Iron deficiency anemia
Anemia of chronic disease (ACD)
Megaloblastic anemia (caused by deficiencies in the B vitamins folate, vitamin B12, or both)

Some less common causes and types of anemia are included in a table in this report.

Blood has two major components:

Plasma is a clear yellow liquid that contains proteins, nutrients, hormones, electrolytes, and other substances. It constitutes about 55% of blood.
White and red blood cells and platelets make up the balance of blood. The white cells are the infection fighters for the body, and platelets are necessary for blood clotting. The important factors in anemia, however, are red blood cells.

Red blood cells (RBCs), also known as erythrocytes, carry oxygen throughout the body to nourish tissues and sustain life. Red blood cells are the most abundant cells in our bodies. Men have about 5.2 million red blood cells per cubic millimeter of blood, and women have about 4.7 million per cubic millimeter of blood.

Hemoglobin and Iron

Each red blood cell contains 200 - 300 hemoglobin molecules. Hemoglobin is a complex molecule, and it is the most important component of red blood cells. It is composed of protein (globulin) and a molecule (heme), which binds to iron.

In the lungs, the heme component binds to oxygen in exchange for carbon dioxide. The oxygenated red blood cells are then transported to the body's tissues, where the hemoglobin releases the oxygen in exchange for carbon dioxide, and the cycle repeats. The oxygen is used in the mitochondria, the power source within all cells.

Red blood cells typically circulate for about 120 days before they are broken down in the spleen. Most of the iron used in hemoglobin can be recycled from there and reused.

Structure and Shape of Red Blood Cells

Red blood cells -- the erythrocytes -- are extremely small and look something like tiny, flexible inner tubes. This unique shape offers many advantages:

It provides a large surface area to absorb oxygen and carbon dioxide.
Its flexibility allows it to squeeze through capillaries, the tiny blood vessels that join the arteries and veins.

Abnormally shaped or sized erythrocytes are typically destroyed and eliminated.

Blood Cell Production (Erythropoiesis)

The actual process of making red blood cells is called erythropoiesis. (In Greek, erythro means "red," and poiesis means "the making of things.") The process of manufacturing, recycling, and regulating the number of red blood cells is complex and involves many parts of the body:

The body carefully regulates its production of red blood cells so that enough are manufactured to carry oxygen but not so many that the blood becomes thick or sticky (viscous).
Most of the work of erythropoiesis occurs in the bone marrow. In children younger than 5 years old, the marrow in all the bones of the body is enlisted for producing red blood cells. As a person ages, red blood cells are eventually produced only in the marrow of the spine, ribs, and pelvis.
If the body needs more oxygen (at high altitudes, for instance), the kidney triggers the release of the hormone erythropoietin (EPO), a hormone that acts in the bone marrow to increase the production of red blood cells.
The lifespan of a red blood cell is 90 - 120 days. The liver and the spleen remove old red blood cells are removed from the blood by the liver and spleen.
When old red blood cells are broken down for removal, iron is returned to the bone marrow to make new cells.

Causes

Iron deficiency anemia occurs when the body lacks mineral iron to produce the hemoglobin it needs to make red blood cells. In general, there are three stages leading from iron deficiency to anemia:

First, there is an insufficient supply of iron, which causes iron stores in the bone marrow to be depleted. This stage generally has no symptoms.
Second, iron deficiencies develop and begin to affect hemoglobin production. (Tests will show low hemoglobin and hematocrit levels.)
Hemoglobin production declines to the point where anemia develops.

Most of the iron used in the body can be recycled from blood and reused. Nevertheless, iron deficiency can occur from a number of conditions.

Inadequate Iron Intake. A healthy diet easily provides enough iron. In general, most people need just 1 mg, and menstruating women need 2 mg of extra iron each day. This means that lack of iron in the diet is not a common cause of iron deficiency anemia, except in infants. In fact, most American adults may be consuming too much iron in their diet. Most of the iron in red blood cells is recycled and reused. Iron-poor diets are a cause of anemia only in people with existing risks for iron deficiency. Children who have not yet eaten iron-fortified formulas or iron-enriched cereal may also become anemic.

Blood Loss. Iron deficiencies most commonly occur from internal blood loss due to other conditions that range in severity. These conditions include:

Peptic ulcers, which may be caused by H. pylori infections, or aspirin and drugs or nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen. About 70% of long-term users of these medications have some sign of gastrointestinal bleeding, although it is rarely significant enough to cause anemia.
Duodenal ulcers
Hemorrhoids
Colon polyps
Colon, stomach, and esophageal cancer
Very heavy periods (menorrhagia) are the most common causes of anemia in premenopausal women.
Bleeding from esophageal varices, often present in alcoholics

Impaired Absorption of Iron. Impaired absorption of iron is caused by:

Certain intestinal diseases (inflammatory bowel disease, celiac disease)
Surgical procedures, particularly those involving removal of parts of the stomach and small intestine, can impair the ability of the stomach or intestine to absorb iron. (Such conditions also often impair folic acid absorption as well.)
Pica, the craving for non-food substances such as ice, starch, or clay, is a possible cause of iron deficiency. To complicate matters, pica (particularly ice cravings) may also be a symptom, rather than a cause, of anemia.
Certain intestinal infections, such as hookworm and other parasites.

Genetic Causes. Some people are born with iron deficiency. Certain cases may be due to a mutation of the Nramp2 gene, which regulates a protein responsible for delivering iron to the cells.

Anemia of chronic disease (ACD), also called anemia of chronic inflammation (ACI), is a common condition associated with a wide variety of persistent inflammatory diseases. It can be very severe and require transfusions.

The Inflammatory Process and ACD. ACD is not completely understood. In ACD, iron is not efficiently recycled from blood cells, and red blood cell survival is reduced. In addition, there is impaired response to erythropoietin, the hormone that acts in the bone marrow to increase the production of red blood cells. (Abnormal function and low levels of erythropoietin, in fact, may be the most important factor in ACD, with iron insufficiencies being a consequence.)

The process leading to ACD may occur in the following way:

The immune system activates white blood cells and releases various compounds during times of infection that are intended to fight invaders and heal wounds. Such an event causes an inflammatory state in the areas of the attack.
White blood cells called macrophages release small but powerful proteins known as cytokines, which are critical in the development of ACD. Cytokines are indispensable for healing. However, cytokines are overproduced often in chronic and inflammatory diseases, causing serious tissue injury and, in some cases, even organ damage. In the case of ACD, they prevent production of erythropoietin, the hormone that acts in the bone marrow to increase the production of red blood cells. Specific cytokines implicated in anemia are interleukin 1 (IL-1), tumor necrosis factor (TNF), and interferons.
As part of this process, mechanisms prevent the release of recycled iron needed in the bone marrow for the manufacturing of red blood cells. Iron absorption in the intestines is also blocked. Theoretically, this is a protective measure, since iron may help infectious organisms proliferate. In such cases, iron stores are high, but the usable iron in circulation is low.
Researchers have identified a peptide called hepcidin, which prevents iron absorption in the intestine and blocks the release of iron by immune factors for red blood cell production. Some experts believe high levels of the peptide may play a central role in preventing the release of iron during infection and inflammatory states, and is critical in ACD.

Diseases Associated with ACD and Inflammation. The chronic diseases that are associated with this process include:

Certain cancers. Examples include lymphomas and Hodgkin's disease.
Autoimmune diseases. Examples include rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease, and polymyalgia rheumatica.
Long-term infections. Examples include chronic or recurrent urinary tract infections and osteomyelitis.
Hepatitis C. The liver cirrhosis associated with hepatitis C can reduce the production of red blood cells. Gastrointestinal bleeding may also contribute to blood loss.
Heart failure. Experts estimate that 25 - 60% of patients with heart failure also have anemia. However, it is unclear whether anemia actually causes or worsens heart failure. Recent research suggests it may actually be a sign (marker) of heart failure. Iron deficiency in heart failure can be due to a number of factors. It may be caused by a lack of nutrients in a person’s diet or by the body’s inability to absorb nutrients from food. Heart failure can also cause a back up of fluid (edema). This edema produces a higher volume of blood plasma (the liquid part of blood), which can dilute red blood cells and cause anemia.
Chronic kidney disease. The hormone erythropoietin (EPO) is produced in the kidneys and stimulates the bone marrow production of red blood cells. Diseased kidneys do not release sufficient amounts of EPO; anemia can result and is universal in end-stage renal disease. Chronic kidney disease is a common complication of diabetes.
HIV/AIDS. The inflammatory process associated with AIDS can adversely affect EPO levels and red blood cell production.
Anemia in critically ill patients. Evidence suggests similarities between ACD and severe anemia in patients who are in intensive care. Some experts believe that the cause of anemia in such critically ill patients may also be due to inflammatory responses that promote impaired responsiveness to erythropoietin.

Not all chronic diseases involve the inflammatory process and anemia. For example, high blood pressure is a chronic disease, but it does not affect red blood cells.

Treatment-Related Anemia. Anemia can also result from the therapies used to treat conditions. For example, anemia is a common side effect of cancer treatments. Chemotherapy and radiation can impair the bone marrow's production of red blood cells and contribute to the extreme fatigue that many patients experience during cancer therapy. Patients with hepatitis C frequently receive combination therapy of ribavirin and interferon; ribavirin can induce anemia. Hepatitis C also affects many patients with HIV or AIDS. In addition to ribavirin, patients with HIV or AIDS can develop anemia as a result of highly active anti-retroviral therapy (HAART) and, in particular, from the drug AZT.

Other medications that increase the risk for anemia are certain antibiotics, some antiseizure medications (phenytoin), immunosuppressive drugs (methotrexate, azathioprine), antiarrhythmic drugs (procainamide, quinidine), and anti-clotting drugs (aspirin, warfarin, heparin).

Megaloblastic anemia is the end-product of deficiencies in the B vitamins folate or vitamin B12 (also called cobalamin), or both. Such deficiencies produce abnormally large red blood cells (megaloblastic ) that have a shortened lifespan. Neurologic problems are also associated with these deficiencies. Several conditions can cause these deficiencies.

Causes of Vitamin B12 Deficiency. Conditions that cause vitamin B12 deficiencies include:

Vitamin B12 deficiency from diet is very rare, since the liver stores over a 3-year supply. It usually does not occur even in alcoholism, vegetarianism, or in malnourished people with kidney failure or cancer. Since animal products are the chief source, however, true vegan vegetarians may need a supplement, fortified food, or appropriate food selection known to contain adequate amounts of this vitamin
Pernicious anemia. Pernicious anemia is an autoimmune disease in which antibodies are tricked into attacking stomach cells. This results in impaired production of intrinsic factor (IF), a compound that is critical for absorption of vitamin B12. Pernicious anemia is diagnosed in about 1% of people over age 60, with women having a higher risk than men.
Complications of gastrointestinal surgery. Surgeries such as stomach bypass or stapling, which remove part or all of the stomach, pose a 15 - 30% chance of causing vitamin B12 deficiencies.
Overgrowth of intestinal bacteria
Tropical sprue (an acquired malabsorption disease occurring in tropical climates)

Causes of Folate Deficiency. The body stores only about 100 times its daily requirements for folate and can exhaust this supply within about 3 months if the diet is deficient in folate.

Poor diet coupled with alcoholism is the most common cause of folate deficiency. Alcohol abuse not only contributes to malnutrition but also causes chemical changes that can result in lower folate levels.
Any condition that disturbs the small intestine and impairs its absorption ability can cause a deficiency. Such disorders include inflammatory bowel disease or celiac sprue (a sensitivity reaction to gluten)

Click the icon to see an image of foods that contain gluten.

Parasitic diseases such as giardiasis
Short bowel syndrome
Deficiencies can also arise due to high demand for folic acid caused by conditions such as cancer, pregnancy, severe psoriasis, severe hyperthyroidism, and hemolytic anemia.
Some drugs, including phenytoin, methotrexate, trimethoprim, and triamterene, may also hinder folate absorption.


Form of Anemia	Description and Diagnosis	Causes and Risk Factors	Treatments
Aplastic Anemia	Bone marrow fails to produce all types of blood cells. Symptoms, in addition to standard anemia, are bleeding in mucous membranes and skin, gingivitis, higher risk for infection, and shortness of breath.	Cause is unknown in half the cases. Known causes include hereditary conditions (Fanconi's anemia), viruses (HIV, hepatitis, Epstein-Barr), autoimmune diseases (lupus, rheumatoid arthritis), medications (valproic acid, tacrolimus, azathioprine) or chemicals (benzene, pesticides).	Transfusions, antibiotics, bone marrow or stem cell transplantation, immunosuppressant drugs. (This anemia used to be nearly always fatal, but survival rates now can reach 92% with successful transplants and up to 87% with immunosuppressants.)
Thalassemia	Genetic blood disease caused by a defect in the rate of production of hemoglobin. The two major forms are thalassemia minor and thalassemia major (Cooley's anemia, beta thalassemia). Thalassemia minor is the more common and milder form, in which lifespan is normal. Thalassemia major can be serious, but it is fortunately very rare.	Affects males and females equally. Most common in people of Mediterranean descent, especially Italians and Greeks. Both types of thalassemia are found in an area that extends from northern Africa and southern Europe to Thailand, including Iran, Iraq, Indonesia, and southern China. Thalassemia major is more common in families who intermarry.	Transfusions to supply enough red blood cells to achieve moderate anemia and avoid iron overload are standard approaches for thalassemia major. Investigations are ongoing to find alternatives to transfusions. Hydroxyurea, 5-azacytidine, erythropoietin, or butyrate analogues may help some patients. Bone marrow transplantation may be needed for some types of thalassemia.
Hemolytic Anemias: Acquired	Anemia caused by hemolysis (premature destruction of red blood cells). Diagnosis considered when there is marked increase in RBC production by bone marrow.	Autoimmune hemolytic anemia is the primary type, in which antibodies produced by the immune system damage RBCs. Cause unknown or associated with disorders such as systemic lupus erythematosus, lymphoma, and paroxysmal nocturnal hemoglobinuria. Other causes are high exposure to certain metals or chemicals (lead, copper, benzene, naphthalene), snake and insect bites, malaria, transfusions, post-surgical complications, and drugs such as methyldopa. In infants, blood group incompatibility between mother and child or infections in the womb.	Corticosteroids for autoimmune hemolytic anemia. Transfusions beneficial in many cases. Various immunosuppressive drugs may be tried, as well as splenectomy. Eculizumab (Soliris) is approved for treatment of paroxysmal nocturnal hemoglobinuria.
Hemolytic Anemias: Inherited	Hemolysis (premature destruction of RBCs) caused by sphere-shaped RBCs, which have difficulties circulating through the spleen.	Inherited defects include membrane defects, hemoglobin abnormalities, and enzyme deficiencies. Fava beans may trigger symptoms. More likely and more serious in males than females.	Blood transfusions may be necessary for some types of hemolytic anemia. Experimental trials use immune globulin. Removal of the spleen (splenectomy) or bone marrow transplantation may help some patients.
Sideroblastic Anemias	Group of anemias caused by impaired ability of bone marrow to produce normal RBCs. Normal-to-high iron levels, but iron cannot be used to make hemoglobin. In addition to the standard symptoms of anemia are jaundice, enlarged liver and spleen, fever, headache, loss of appetite, vomiting, and leg sores. Symptoms can be mild. Usually appears in childhood. Infections, trauma, and pregnancy may trigger symptoms.	Inherited or acquired after excessive alcohol use, certain medications, including chloramphenicol, or other disorders, including some cancers and rheumatoid arthritis. More common in the elderly.	Deferoxamine (Desferal) is used to remove iron. Effectiveness is increased when ascorbate is added to the regimen. Folate and pyridoxine are used, but their effectiveness is under question.
Sickle Cell Anemia	Serious, life-threatening, inherited disease. The sickle-shaped, inflexible RBC has impaired ability to squeeze through vessels. Short lifespan of RBC (10-20 days) causes anemia. In addition to anemia symptoms, joint and bone pain, infections, and heart failure can occur.	Disease occurs in 0.6% and the trait is found in the genetic makeup of 9% of African-Americans. Also occurs in people from India and Spanish-speaking and Mediterranean regions.	Measures to avoid cycling and control pain. Including hydration, hydroxyurea, NSAIDs and narcotic analgesics. Bone marrow transplantation. [For information, see In-Depth Report #58: Sickle-cell disease.]

Risk Factors

Although nutritional iron-deficiency anemia has declined in industrialized nations, it affects an estimated 2 billion people worldwide. Even in the U.S., iron deficiency is the most prevalent nutritional deficiency. It is highly associated with poverty. People in lower socioeconomic groups have double the risk of those who are middle or upper class.

Among Americans with iron deficiency anemia, young children have the highest risk followed by premenopausal women. Adolescent and adult men and postmenopausal women have the lowest risk. Men, in fact, are at risk for iron overload, probably because of their higher meat intake.

General Risk Factors for Anemia in Infants and Children. Up to 20% of American children and 80% of children in developing countries become anemic at some point during their childhood and adolescence. Iron deficiency is the most common cause in children, but other forms of anemia, including hereditary blood disorders, can also cause anemia in this population. Hispanic American children have double the rates of iron deficiency as African-American and Caucasian children.

Iron deficiency affects about 9% of children younger than 2 years. About 3% of children in this age group are anemic as a result. Children in lower-income homes are at higher risk than those in higher income homes. In a study of low-income children, ages 6 months to 5 years, the prevalence of anemia was over 10%, and was nearly 18% in children younger than 2 years. However, children in any income group can develop iron deficiency.

Young children 9 - 18 months have the highest risk for iron deficiency anemia in the U.S. Such children also are at great risk for problems in mental development from anemia. Infant boys may have 10 times more risk than baby girls. In general, full-term, breast-fed infants have enough iron stores for their first 6 months of life. After that, they must rely on other sources for iron.

Iron-deficiency anemia in infants and small children can be due to one or more of the following factors:

Stopping breast-feeding too early or using formula that isn't iron-fortified.
Bottle-feeding too long. Studies indicate that the longer children are bottle-fed, the greater the risk for iron-deficiency and anemia. Toddlers 12 months and older should not drink more than 2 cups of milk a day. Cow’s milk is good for children, but it does not contain enough iron. Too much milk can decrease children’s appetite and prevent them from eating the iron-rich food they need. When babies who are bottle-fed are 7 - 9 months old, they should be weaned from bottles and given sippy cups. By the age of 12 months, all children should be using a cup instead of a bottle.
Toddlers’ preferences for iron-poor food. Parents should make sure that their children eat iron-rich foods, such as beans, meat, fortified cereals, eggs, and green leafy vegetables

Better social services and more accurate ways of diagnosing and monitoring anemia are needed in these high-risk groups. There is still considerable debate on how to define iron deficiency and anemia in infants. New research suggests that a reticulocyte hemoglobin content (CHr) test may be better than a standard hemoglobin test for detecting iron deficiency in babies. Reticulocytes are immature red blood cells. The CHr test measures the amount of hemoglobin in these cells.

Up to 10% or more of adolescent and adult women under 49 years are iron deficient. Hispanic American and African-American women have double the prevalence for anemia compared to Caucasian women. The risk for anemia in adolescent girls is about 3%. Anemia is generally mild in young women, however, and is more likely to occur with one or more of the following conditions:

Heavy menstruation for longer than 5 days
Abnormal uterine bleeding, such as from fibroids
Pregnancy. About 20% of women in industrialized countries have iron deficiency during pregnancy. Multiple pregnancies and births significantly increase the risk.

Although studies have reported various estimates on the prevalence of anemia in older adults, one survey suggested that anemia affects about 10% of adults aged 65 years and older, and more than 20% aged 85 years and older. The causes of anemia in older adults were equally distributed among nutritional deficiencies, chronic inflammatory disease, chronic renal disease, and unexplained anemia. Most cases were mild.

People with alcoholism are at risk for anemia both from internal bleeding as well as folate- and vitamin B deficiency-related anemias.

Although most Americans probably consume too much iron in their diets, some people may be at risk for diet-related iron deficiencies, including:

People whose diets are high in processed foods and lack any meat.
Strict vegetarians. Vegetarians who avoid all animal products may have a slightly higher risk for deficiencies in iron and some B vitamins. Although dried beans and green vegetables often contain iron, it is less easily absorbed from plants than from meat. Fortunately, most commercial cereals are fortified with vitamin B12 and folic acid (the synthetic form of folate).

Anyone with a chronic disease that causes inflammation or bleeding is at risk for anemia. Critical illness in the intensive care unit is also highly associated with anemia.

Working out regularly may cause some iron loss, which is comparable to that from menstruation and rarely worrisome. Dietary choices may account for most cases of sports anemia. Intense, sustained exercise, such as that performed by marathon runners, may cause a condition called sports anemia, which may be due to slight gastrointestinal bleeding, damaged red blood cells, low iron intake, or poor intestinal absorption of iron.

Iron deficiency occurs in 20% of pregnant women in developed countries. Even worse, 50% or more of women in nonindustrialized nations become iron deficient, and 30 - 50% are deficient in folic acid. Severe anemia is associated with a higher mortality rate among pregnant women. Mild-to-moderate anemia, however, does not pose any elevated risk.

Pregnancy increases the risk for anemia in different ways:

It increases the body's demand for folic acid and, therefore, poses a risk for deficiencies and an increased risk for megaloblastic anemia. Low levels of folate during pregnancy increase the risk of neural tube defects in newborns.
It increases the body's demand for iron, thus posing a risk for iron deficiency anemia. Pregnant or nursing women need 30 mg of iron per day. Maternal iron deficiency anemia is associated with increased weight or size of the placenta, a condition that may later pose a risk for high blood pressure in the offspring. Pregnant women with low hemoglobin levels (the iron-bearing component in the blood) have an elevated risk for pre-term or low birth weight infants.
Pregnancy is also associated with fluid retention, which in turn may produce high volumes of plasma (the fluid component of blood). This can dilute red blood cells, which may lead to anemia.
After delivery, heavy bleeding, which occurs in 5 - 10% of women who have given birth, can cause symptoms of anemia.

Diagnosing of Iron Deficiency During Pregnancy. A diagnosis of iron deficiency is problematic in pregnant women. The standard test is a measurement of ferritin levels, which are low in most people with iron deficiency. Pregnant women, however, may have high ferritin blood levels into their third trimester but still be iron deficient. A newer test that measures a factor called serum transferrin receptor may prove to be a useful way of diagnosing iron deficiency in women. Researchers are also investigating Doppler ultrasonography as an imaging technique for detecting anemia in the fetus. Traditionally, fetal anemia is diagnosed through amniocentesis. Doppler ultrasonography is a non-invasive method that does not risk causing a miscarriage or a worsening of fetal anemia.

Preventing Anemia in Pregnant Women.

Iron Supplements. For the past 40 years, iron supplements have been recommended for all pregnant women. This practice has been challenged recently, however. There is no clear-cut evidence that the mild iron deficiency most pregnant women experience is harmful. In addition, iron supplements cause gastrointestinal side effects and may not be completely harmless. Some experts suggest iron supplements for all pregnant women whose hemoglobin levels are less than 11 g/dl, and pregnant women whose serum ferritin levels are low, beginning in their 20th - 24th weeks of pregnancy.
Vitamin Supplements. Women who are trying to conceive, who are pregnant, and who are breast-feeding should take 400 mcg of folic acid a day. They should be sure this is folic acid and not folate. Folate is the natural form of folic acid, but 400 mcg supplements of folate are half as potent as the same dose of folic acid. Pregnant and nursing women who are vegetarians should be sure to have supplements of folic acid and other B vitamins as well, since many of these nutrients are found primarily in animal products. Vitamin B12 deficiencies during pregnancy can also produce anemia in both mother and child.
Diets Rich in Vitamin C. Eating foods rich in vitamin C can help absorb iron.

Treating Anemia During Pregnancy. Pregnant women who become anemic and need treatment may be given oral iron supplements, or blood transfusions in severe cases. Intravenous or intramuscular administration of iron helps improve blood levels better than oral iron supplements, but may cause more serious side effects.

Complications

Most cases of anemia are mild, including those that occur as a result of chronic disease. Nevertheless, even mild anemia can reduce oxygen transport in the blood, causing fatigue and a diminished physical capacity. Moderate-to-severe iron-deficiency anemia is known to reduce endurance. Some studies indicate that even iron deficiency without anemia can produce a subtle but still lower capacity for exercise.

Because a reduction in red blood cells decreases the ability to absorb oxygen from the lungs, serious problems can occur in prolonged and severe anemia that is not treated. Anemia can lead to secondary organ dysfunction or damage, including heart arrhythmia and heart failure.

Certain inherited forms of anemia, including thalassemia major, pernicious anemia, and sickle-cell anemia, can be life threatening. Thalassemia major and sickle-cell anemia affect children and are particularly devastating.

Pregnant women with significant anemia may have an increased risk for poor pregnancy outcomes, particularly if they are anemic in the first trimester.

In children, severe anemia can impair growth and motor and mental development. Children may exhibit a shortened attention span and decreased alertness. Children with severe iron-deficiency anemia may also have an increased risk for stroke.

Anemia is common in older people and can have significantly more severe complications than anemia in younger adults. Some studies have reported higher mortality rates in anemic individuals 85 and older compared to their non-anemic peers. (The rates were higher in anemic men than in women.) The following are examples of its effects from different studies:

Anemia may have adverse effects on the heart and increase the severity of cardiac conditions, including reducing survival rates from heart failure and heart attacks.
Elderly people with lower levels of hemoglobin are at an increased risk of death.
Anemia may be associated with an increased incidence of falls.
Even mild anemia may possibly lead to cognitive impairment. A 2006 study of elderly women found that mild anemia worsened problem-solving abilities and other cognitive functions. Anemia may worsen an already existing dementia.

In addition to anemia, vitamin B12 deficiency can cause neurologic damage, which can be irreversible if it continues for long periods without treatment.

Anemia is particularly serious in cancer patients. In people with many common cancers, the presence of anemia is associated with a shorter survival time.

Anemia is associated with higher mortality rates and possibly heart disease in patients with kidney disease.

The combination of anemia and heart failure can increase the risk of hospitalization or death by 30 - 60%. Patients with heart failure whose hemoglobin levels decline do worse than patients with stable levels.

Blood transfusions. Patients with certain types of anemia require frequent blood transfusions. These transfusions can cause iron overload. Patients are treated with iron chelation therapy, which uses a drug that binds to iron. Excess iron is then eliminated by the kidneys. The standard drug for iron chelation therapy, deferoxamine (Desferal), is injected intravenously through an infusion pump. The treatment can be difficult for many patients. In 2005, the FDA approved a new drug, deferasirox (Exjade), to treat iron overload due to blood transfusions. Patients dilute the pills in liquid once a day and drink the mixture.

Symptoms

Symptoms of anemia vary depending on the severity of the condition. Anemia may occur without symptoms and be detected only during a medical examination that includes a blood test. When they occur, symptoms may include:

Weakness and fatigue are the most common symptoms of even mild anemia. Even iron deficiency without anemia can reduce working capacity in some people.
Shortness of breath on exertion
Rapid heartbeat
Lightheadedness or dizziness
Headache
Ringing in the ears (tinnitus)
Irritability and other mood disturbances
Pale skin (however, healthy-looking skin color does not rule out anemia if a patient has risk factors and other symptoms of anemia)
Mental confusion
Loss of sexual drive

Pica. One odd symptom, in some cases a cause of iron deficiency, is pica. This is the habit of eating unusual substances, such as ice (called pagophagia), clay, cardboard, foods that crunch, or raw starch. For example, in one study, half of people whose pica took the form of pagophagia (eating at least one tray of ice every day for 2 months) or eating foods that crunch (such as raw potatoes, carrots, or celery) were iron deficient. The pica often stops, particularly in children, when iron supplements are given. Pica is difficult to detect because patients are often ashamed to admit to such cravings.

Frequent Breath Holding. Studies have also indicated that children who hold their breath frequently when angry or upset, even to the point of fainting, may be iron-deficient. In one study, taking iron supplements reduced this phenomenon in 88% of treated children.

Symptoms of Megaloblastic Anemia. The symptoms of megaloblastic anemia from vitamin B12 or folic acid deficiencies include not only standard anemic symptoms but also:

Inflammation of the mouth (stomatitis)
Inflammation of the tongue (glossitis), which involves shrinkage at the surface and edges of the tongue

Over time, psychiatric and neurologic problems develop. Vitamin B12 deficiencies cause neurologic symptoms (numbness and tingling, depression, memory loss, and irritability), and folate deficiency may result in depression and dementia (in severe cases).

Symptoms of Pernicious Anemia. Early neurologic symptoms of pernicious anemia are due to B12 deficiency. They include numbness and tingling, depression, memory loss, and irritability. Advanced nerve damage can cause loss of balance and staggering, confusion, dementia, spasticity, loss of bladder control, and erectile dysfunction. Folic acid deficiency does not cause neurologic damage, although people with this deficiency can be irritable, forgetful, and experience personality changes. Of concern for patients with pernicious anemia and B12 deficiency anemia is that folic acid supplements can mask the presence of this disease in its early stages but not cure it. The only cure is vitamin B12 supplementation.

Diagnosis

The first step in any diagnosis is a physical examination to determine if the patient has symptoms of anemia and any complications. Because anemia may be the first symptom of a serious illness, determining its cause is very important. This may be difficult, particularly in the elderly, malnourished, or people with chronic diseases, whose anemia may be caused by one or more factors. A detailed medical, personal, and dietary history should report:

Any family or personal history of anemia
A history of gallbladder disease, jaundice, or enlarged spleen
Heavy menstrual bleeding in women
Any occurrence of blood in the stool or other signs of internal bleeding. (Even if the patient has not observed any bleeding, nonvisible blood may be present, so a rectal exam and stool test are essential.)
Any dietary history, particularly in people who are elderly, poor, or both

The doctor should examine the patient carefully, especially checking for swollen lymph nodes, an enlarged spleen, and pale skin and nail color.

Specific blood tests are given to determine anemia from any cause.

Blood and Hemoglobin Counts. A complete blood count (CBC) test is performed to determine the presence of anemia. The red blood cells, or erythrocytes, and their iron-bearing component, hemoglobin, are measured.

For example, severe anemia in adults is defined by the World Health Organization as:

Hemoglobin concentrations below 12 g/dL (7.5 mmol/L) in women. (Some evidence suggests that in older women anemia should be diagnosed at 13 g/dL and below.)
Below 13 g/dL (8.1 mmol/L) in men.

A low red blood cell (RBC) count could indicate a number of problems, including bleeding or a failure by bone marrow to manufacture red blood cells.

Hematocrit. Calculating the percentage of red blood cells in blood plasma (a measurement called the hematocrit) is also important. Plasma is the liquid portion of blood. People with a high volume of plasma may be anemic even if their blood count is normal because the blood cells have become diluted.

Normal percentages are highest in the very youngest individuals and decline as people age. They also vary by gender. The following are some examples of normal range:

Newborns: 42 - 60%
Children: 35 - 45%
Adult males: 41 - 53%
Adult women: 36 - 46%

Normal value ranges may vary slightly among different laboratories.

Smokers, people at high altitudes, and those who are dehydrated tend to have higher than normal hematocrit levels. Those at greater risk for low hematocrit levels include pregnant women and patients with cirrhosis, heart failure, and splenomegaly.

Reticulocyte Count. Reticulocytes are immature red blood cells, and their count reflects the rate of red blood cell production. The upper normal limit is about 100,000/mL. A low count, when bleeding isn't the cause, suggests problems in production in the bone marrow. An abnormally high count indicates that the red blood cells are being destroyed in high numbers and indicates hemolytic anemia. New research suggests that the reticulocyte hemoglobin content (CHr) test may be more accurate than a standard hemoglobin test for detecting iron deficiency in infants. This test may help identify babies who are at risk for becoming anemic and help them get treated earlier.

Blood Morphology. A blood smear viewed under a microscope allows an expert to classify the blood by its color, size, and shape ( morphology ). Generally red blood cells are categorized as:

Pale-colored (hypochromic) and abnormally small (microcytic)
Normal colored and normal sized (normochromic, normocytic)
Abnormally large (macrocytic)

The shape of the red blood cells, which can be distorted in many blood disorders, is also important in determining a diagnosis.

There are two steps in making a diagnosis in patients with symptoms of iron deficiency anemia:

The first step is to determine if a person is actually deficient in iron.
If iron stores are low, the second step is to diagnose the cause of the iron deficiencies, which will help determine treatment.

Determining if Iron Stores are Low. The following findings are important in determining that a person is iron deficient:

Blood cells viewed under the microscope are pale (hypochromic) and abnormally small (microcytic). They are also mostly uneven in shape. (These findings suggest iron deficiency, but they can also appear in cases of anemia due to chronic disease and thalassemia.)
Hemoglobin and iron levels are low. (These findings further suggest iron deficiency, but they can also occur in cases of anemia due to chronic disease.)
Ferritin levels are low. Ferritin is a protein that binds to iron. Low levels typically mean reduced iron stores. High ferritin levels in the blood do not always mean sufficient iron stores. For example, pregnant women may have high ferritin levels into their third trimester but still be iron deficient. Ferritin levels may also be normal or even elevated in patients with inflammation from anemia due to chronic disease, even if they also have low iron stores.
In children with iron deficiencies, reticulocytehemoglobin levels are low. Reticulocytes are immature red blood cells, and this test may be the most effective approach for diagnosing iron deficiency in children.
A test that measures a factor called serum transferrin receptor (TfR) is proving to be very sensitive in identifying iron deficiency in problematic patients, including the elderly with chronic diseases and possibly pregnant women. (It is often very difficult to identify iron deficiencies in patients who also have anemia due to chronic diseases because their ferritin levels are often normal or even high.) For example, levels of TfR are high in patients with ACD and iron deficiency anemia, but they are normal or only slightly raised in ACD alone. The test is expensive, however, and some experts recommend it should be used only when there is a high suspicion of iron deficiency in the elderly.
Measuring erythrocyte zinc protoporphyrin (ZPP), a product of abnormal heme synthesis, is under investigation and may prove to be a simple and precise measure of iron deficiencies, particularly in children.

If internal bleeding is suspected as the cause, the gastrointestinal tract is usually the first suspect as the source. A diagnosis in these cases can often be made if the patient has noticed blood in the stools, which can be black and tarry or red-streaked. Often, however, bleeding may be present but not visible. If so, stool tests for this hidden (occult ) blood are required. Additional tests may then be needed to diagnose the precipitating condition. Endoscopy, in which a fiber optic tube is used to view into the gastrointestinal tract, is helpful in many patients, particularly when the source of bleeding is unclear. A colonoscopy may also be recommended to rule out colorectal cancer.

If the patient's diet suggests low iron intake and other causes cannot be established using inexpensive or noninvasive techniques, then the patient may simply be given a monthly trial of iron supplements. If the patient fails to respond, further evaluation is needed.

Usually anemia of chronic disease is recognized during the management of the primary disease and, if the anemia is mild, additional diagnostic tests are rarely needed. The following are typical findings in ACD:

The blood cells are normal looking.
Blood tests may typically show low levels of iron in the blood, but ferritin levels are normal or even high. (Low levels of ferritin, a protein that binds to iron, indicate iron deficiency.)

Doctors need a multi-step diagnostic procedure for determining vitamin B deficiencies and the anemias that cause or are caused by them. Doctors may arrive at a diagnosis of vitamin B12 or folic acid deficiencies from different routes:

They may diagnose deficiencies after detecting megaloblastic anemia from abnormal blood tests.
They may suspect vitamin deficiencies first from symptoms and history and then look for anemia.

Diagnosing Megaloblastic Anemia. Very large oval red blood cells indicate megaloblastic anemia. Abnormally shaped neutrophils (certain white blood cells) may also be present. Bone marrow aspiration may need to be performed if the disease is strongly suspected but the diagnosis is not clear.

Determining Vitamin Deficiency. Once megaloblastic anemia has been diagnosed, the doctor will need to determine which vitamin deficiency is causing it. This is extremely important, because if a vitamin B12-deficient patient receives folate replacement only, then irreversible nerve injuries may develop. Even if blood tests for megaloblastic anemia are normal, patients with neurologic and psychiatric abnormalities that have no detectable cause should still be tested for vitamin B12 deficiency.

Often, vitamin B deficiencies cannot be determined by a history or symptoms alone. Blood tests are the primary indicators of both vitamin B12 and folic acid deficiencies, but even blood tests for these vitamins are not always straightforward:

Folic acid and vitamin B12 levels must always be measured at the same time because each vitamin may affect the other.
Folate levels may be temporarily low in some people who are not truly deficient.
Folate levels may temporarily rise in deficient people if they have just eaten foods containing the vitamin.
Antibiotics can interfere with B12 levels.

Measuring methylmalonic acid and homocysteine, substances in the blood that increase when levels of one or both vitamins are low, improves accuracy.

Tests for Pernicious Anemia. Once a vitamin B12 deficiency has been established and the doctor has not found any intestinal abnormalities or other factors to account for the deficiency, the doctor presumes a diagnosis of pernicious anemia. Pernicious anemia may also be diagnosed through various blood (such as complete blood count) or urine tests.

Pernicious anemia is treated with vitamin replacement, but the condition is easily missed, particularly in patients whose diets are rich in folic acid. Folic acid can mask the early symptoms of pernicious anemia but not cure it. Consequently the disease may persist until serious neurologic symptoms occur. With folic acid now a required additive in many commercial foods, some experts are concerned about an increased incidence in pernicious anemia.

Dietary Factors

Iron found in foods is either in the form of heme or non-heme iron:

Heme Iron. Foods containing heme iron are the best sources for increasing or maintaining healthy iron levels. Such foods include (in decreasing order of iron-richness) clams, oysters, organ meats, beef, pork, poultry, and fish.
Non-Heme Iron. Non-heme iron is less well-absorbed. About 60% of the iron in meat is non-heme (although meat itself helps absorb non-heme iron). Eggs, dairy products, and iron-containing vegetables have only the non-heme form. Such vegetable products include dried beans and peas, iron-fortified cereals, bread, and pasta products, dark green leafy vegetables (chard, spinach, mustard greens, kale), dried fruits, nuts, and seeds.

The absorption of non-heme iron often depends on the food balances in meals. The following foods and cooking methods can enhance absorption of iron:

Meat and fish not only contain heme iron -- the best form for maintaining stores -- but they also help absorb non-heme iron.
Increasing intake of vitamin-C rich foods, such as orange juice, may enhance absorption of non-heme iron, although it is not clear if it improves iron stores in iron-deficient people. In any case, vitamin-C rich foods are healthy and include broccoli, cabbage, citrus fruits, melon, tomatoes, and strawberries.
Riboflavin (vitamin B2) may help enhance the response of hemoglobin to iron. Food sources include dairy products, liver, and dried fortified cereals.
Cooking methods can enhance iron stores. Cooking in cast iron pans and skillets is well-known to increase the iron content of food. According to one study, boiling, steaming, or stir-frying in utensils composed of any material significantly increased the release of non-heme iron stored in vegetables.
Vitamins B12 and folate are important for prevention of megaloblastic anemia and for good health in general. The only natural dietary sources of B12 are animal products, such as meats, dairy products, eggs, and fish (clams and oily fish are very high in B12). As is the case with other B vitamins, however, B12 is added to commercial dried cereals. The recommended daily allowance (RDA) is 2.4 mcg a day. Deficiencies are rare in young people, although the elderly may have trouble absorbing natural vitamin B12 and require synthetic forms from supplements and fortified foods.

Folate is best found in avocado, bananas, orange juice, cold cereal, asparagus, fruits, green, leafy vegetables, dried beans and peas, and yeast. The synthetic form, folic acid, is now added to commercial grain products. Vitamins are usually made from folic acid, which is about twice as potent as folate. Many experts now recommend that adults have 400 mcg of folic acid daily -- considerably higher than standard recommendations of 400 mcg of folate. Women who are trying to conceive, who are pregnant, and who are breast-feeding should take 400 mcg of folic acid.

Click the icon to see an image of sources of folate.

The Recommended Daily Allowance (RDA) of iron for people who are not iron deficient varies by age group and other risk factors. (Iron supplements are rarely recommended in people without evidence of iron deficiency or anemia.) The RDA recommends these daily amounts of iron:

Children 1 - 3 years old: 10 mg
Teenage boys: 12 mg
Teenage girls and premenopausal women: 15 mg
Pregnant or nursing women: 30 mg
Adult men (up to age 50): 10 mg
Older men and women (over age 50): 10 mg

The main source of iron for an infant from birth to 1 year of age is in milk, from breast milk, iron-fortified infant formula, or cereal. The best methods for preventing iron deficiency during infancy are:

Breast-feeding and Iron-Supplemented Formulas. Mothers should be encouraged to breast-feed their babies for their first year. Up to half of the iron in breast milk is absorbed by the baby and is sufficient to prevent anemia for the first 4 - 6 months, assuming that the mother had adequate iron stores during pregnancy. Breast milk itself is low in iron, but if the mother's diet is healthy, vitamin C and lactose in the breast milk may enhance iron absorption. Breast-fed babies should have iron supplements after 4 - 6 weeks, even if they are still nursing.

Infants who are not breast-fed should start with iron-fortified formulas (7-12 mg/L). Most experts strongly discourage the use of low-iron formulas (less than 4.0 mg/L). Parents should discuss the best formula with their doctor. Children given iron supplements may have a slightly higher risk for diarrhea. Experts advise against cow's milk for the first year of life. When cereals are begun, they should be iron fortified.

Recommendations for Toddlers. Toddlers who did not have iron supplements during infancy should be checked for iron deficiency. After the first year, children should be given a varied diet that is rich in sources of iron, B vitamins, and vitamin C. Milk does not contain enough iron and can decrease children's appetite for iron-rich foods. Toddlers older than 1 year should not drink more than 2 cups of milk a day. A preference for apple juice over vitamin-C rich orange juice does not reduce iron absorption in children with any otherwise healthy diet.

Treatment

Oral iron supplements are the best way to restore iron levels for people who are iron deficient, but they should be used only when dietary measures have failed. However, iron supplements cannot correct anemias that are not due to iron deficiency.

One study reported that doctors prescribed iron pills for 64% of patients with anemia, without performing tests to confirm whether iron deficiency was actually the cause. The study suggested that iron replacement was appropriate in less than half of these patients. Iron replacement therapy can cause gastrointestinal problems, sometimes severe ones. Excess iron may also contribute to heart disease, diabetes, and certain cancers. Experts generally advise against iron supplements in anyone with a healthy diet and no indications of iron deficiency anemia. However, one study suggested that supplements help reduce fatigue in women with low iron stores but no signs of anemia.

Treatment of Anemia of Chronic Disease. In general, the best treatment for anemia of chronic diseases is treating the disease itself. In some cases, iron deficiency accompanies the condition and requires iron replacement. Erythropoietin, most often administered with intravenous iron, is used for some patients.

Treatment of Megaloblastic Anemia. The standard treatments for megaloblastic anemia are vitamin B12 injections and folic acid replacement.

Supplement Forms. To replace iron, the preferred forms of iron tablets are ferrous salts, usually ferrous sulfate (Feosol, Fer-In-Sol, Mol-Iron). Other forms include ferrous fumarate (Femiron, FerroSequels, Feostat, Fumerin, Hemocyte, Ircon), ferrous gluconate (Fergon, Ferralet, Simron), polysaccharide-iron complex (Niferex, Nu-Iron), and carbonyl iron (Elemental Iron, Feosol Caplet, Ferra-Cap). Specific brands and forms may have certain advantages. The following are some examples:

Prolonged-release ferrous sulfate (Slow Fe) may enhance iron absorption with fewer side effects than standard ferrous sulfate pills.
FerroSequels contains a stool softener, which helps prevent constipation.
Polysaccharide-iron complex has fewer side effects and equal absorption rates compared to ferrous salts. It is very expensive, however.
Carbonyl iron is composed of very fine tiny uniform spheres of iron powder and may prove to be less toxic than ferrous iron.
Coated or combination pills do not appear to offer any additional advantages and may hinder absorption of the iron.

Regimen. The general guidelines for iron replacement are as follows:

For adults, doctors usually advise one ferrous sulfate tablet (300 mg) three times a day.
Iron replacement doses for children with deficiencies are significantly lower. In general, they are given as drops or syrup administered three times a day. A single-dose daily regimen is showing promise. IMPORTANT: As few as three adult iron tablets can poison children, even fatally. This includes any form of iron pill.
No one, even adults, should take a double dose of iron if one is missed.

Other tips for taking iron are as follows:

For best absorption, iron should be taken between meals. (Iron may cause stomach and intestinal disturbances, however, and some experts believe that low doses of ferrous sulfate can be taken with food and are still absorbed but with fewer side effects.)
Always drink a full 8 ounces of fluid with an iron pill. Taking orange juice with an iron pill may help increase iron absorption. (Some doctors also recommend taking a vitamin C supplement with the iron pill.)
Tablets should be kept in a cool place. (Bathroom medicine cabinets may be too warm and humid, which may cause the pills to disintegrate.)

Full recovery takes 6 - 8 weeks. Recovery will take longer in people with internal bleeding that is not under control. Iron replacement therapy must continue for about 6 months, even if anemia has been reversed. Treatment must be continued indefinitely for people with chronic bleeding; in such cases, iron levels should be closely monitored.

Side Effects. Common side effects of iron supplements include the following:

Constipation and diarrhea are very common. They are rarely severe, although iron tablets can aggravate existing gastrointestinal problems such as ulcers and ulcerative colitis.
Nausea and vomiting may occur with high doses, but can be controlled by taking smaller amounts. Switching to ferrous gluconate may help some people with severe gastrointestinal problems.
Black stools are normal when taking iron tablets. In fact, if they do not turn black, the tablets may not be working effectively. This tends to be a more common problem with coated or long-acting iron tablets.
If the stools are tarry looking as well as black, if they have red streaks, or if cramps, sharp pains, or soreness in the stomach occur, gastrointestinal bleeding may be causing the iron deficiency and the patient should call the doctor promptly.
Acute iron poisoning is rare in adults but can be fatal in children who take adult-strength tablets.

Interactions with Other Drugs. Certain medications, including antacids, can reduce iron absorption. Iron tablets may also reduce the effectiveness of other drugs, including the antibiotics tetracycline, penicillamine, and ciprofloxacin and the Parkinson's disease drugs methyldopa, levodopa, and carbidopa. At least 2 hours should elapse between doses of these drugs and iron supplements.

Supplements. The following vitamin and mineral supplements may improve iron absorption:

Adding either ascorbic acid (vitamin C) or succinic acid to ferrous sulfate therapy will improve absorption of iron stores.
Some studies have found that the addition of zinc to iron supplements increases hemoglobin levels more than iron alone. Some evidence for this suggests that zinc affects a hormone called insulin-like growth factor-I (IGF-I), which plays a role in the regulation of red blood cell production.

In some cases, iron is administered through muscular injections or intravenously. Intravenous iron has the advantage of causing less gastrointestinal discomfort and inconvenience. It may be in the form of iron dextran (Dexferrum, InFed), sodium ferric gluconate complex in sucrose (Ferrlecit), or iron sucrose (Venofer). Ferrlecit or Venofer are proving to be at least equally effective and safer than iron dextran.

Candidates. The injected or intravenous forms should be limited to the following patients with iron deficiency:

People with iron deficiency anemia in whom oral therapy has clearly failed.
Patients with bleeding disorders in which blood loss continues to exceed the rate at which oral iron is absorbed.
In emergencies, when people need red blood cells but transfusion is not appropriate or available.
In people with serious gastrointestinal disorders, such as inflammatory bowel disease, who cannot take iron therapy by mouth.
People undergoing hemodialysis who receive supplemental erythropoietin therapy. Sodium ferric gluconate complex in sucrose (Ferrlecit) or iron sucrose (Venofer) is specifically approved as first-line therapy for these patients.

Certain patients, even if they meet these qualifications, may not be appropriate candidates or should be monitored closely for complications. They include:

Patients with any underlying autoimmune disease.
Malnourished patients who also have an underlying infection.
Patients who are at risk for iron overload.

Side Effects. Some side effects differ depending on how the iron is administered and include the following:

Muscular injections include pain at the site.
Intravenous administration can cause pain in the vein, flushing, and metallic taste, all of which are brief.

For both methods, side effects and serious complications can include:

Blood clots
Fever
Joint aches
Headache
Rashes
A delayed reaction of joint and muscle aches, headache, and malaise occurs 1 - 2 days after the infusion (most commonly with iron dextran) in about 10% of patients. These symptoms respond quickly to NSAIDs, such as ibuprofen or naproxen, in most people.
Iron toxicity. Symptoms include nausea, dizziness, and a sudden drop in blood pressure. Sodium ferric gluconate in sucrose (Ferrlecit) or iron sucrose (Venofer) may pose a lower risk for toxicity than iron dextran.
Allergic reactions. Allergic reactions that occur with intravenous iron can be very serious and, in rare cases, even fatal. Iron dextran appears to pose a much higher risk than sodium ferric gluconate complex in sucrose or iron sucrose, although allergic reactions can also occur with the latter forms.

Oral and injected iron should never be given at the same time. Intravenous iron therapy may be appropriate for some pregnant women who meet these requirements, depending on the pregnancy term and other factors.

Transfusions are used to replace blood loss due to injuries and during certain surgeries. They are also commonly used to treat severely anemic patients who have thalassemia, sickle cell disease, myelodysplastic syndromes, or other types of anemia. Some patients require frequent blood transfusions. Iron overload can be a side effect of these frequent blood transfusions. If left untreated, iron overload can lead to liver and heart damage.

Iron chelation therapy is used to remove the excess iron caused by blood transfusions. Patients take a drug that binds to the iron in the blood. The excess iron is then removed from the body by the kidneys. For many years, deferoxamine (Desferal) was the only drug used in chelation therapy. This drug is usually injected intravenously, using an infusion pump. The infusion can last 8 - 12 hours and may be needed 5 - 7 days a week until iron levels are normal. A new drug, deferasirox (Exjade), was approved in 2005 for children and adults as a once-daily treatment for iron overload due to blood transfusions. It does not require injections. Patients mix the deferasirox tablets in liquid and drink the medicine. Doctors hope that this new drug may make it easier for patients to tolerate chelation therapy. Studies have shown that deferasirox works as well as deferoxamine in ridding the body of excess iron.

Bloodless Medicine. Bloodless medicine and surgery is a new field designed to reduce or minimize blood loss and transfusions. It also attempts to address the problems in treating certain religious groups, such as Jehovah's Witnesses, who refuse transfusions. Some techniques involved in this field include new surgical procedures or drugs that minimize blood loss, the use of erythropoietin, volume expanders (administration of fluids to dilute blood), using tiny blood samples for testing, and methods (Cell Saver) for recovering and recycling blood during surgery.

Erythropoietin is the hormone that acts in the bone marrow to increase the production of red blood cells. It has been genetically engineered as recombinant human erythropoietin (rHuEPO) and is available as epoetin alfa (Epogen, Procrit, and Eprex). Novel erythropoiesis stimulating protein (NESP), also called darbepoetin alfa (Aranesp), lasts longer in the blood than epoetin alfa and requires fewer injections. These medications are also called “erythropoiesis-stimulating drugs.”

Levels of erythropoietin are reduced in anemia of chronic disease. Injections of synthetic erythropoietin can help increase the number of red blood cells in order to avoid receiving blood transfusions. Erythropoietin is used to treat anemia. It does not help improve anemia symptoms, fatigue, or quality of life for patients with cancer or HIV. This drug can cause serious side effects, including blood clots, and is approved only for treating patients with anemia related to the following conditions:

Cancer. For select patients, erythropoietin is used to treat the anemia associated with chemotherapy.
Chronic kidney failure. Erythropoietin is an important anemia treatment for patients with chronic kidney failure, including those on dialysis.
HIV/AIDS. Erythropoietin helps treat the anemia caused by zidovudine (AZT) therapy.

In November 2007, the Food and Drug Administration (FDA) made major changes to the prescribing information for erythropoiesis-stimulating drugs. The new labels describe in detail the risks that Aranesp, Epogen, and Procrit can pose to patients with cancer and chronic kidney disease. The FDA has also established separate dosing recommendations for each of these conditions.

Erythropoiesis-Stimulating Drugs and Cancer. Erythropoietin should be used only to treat anemia caused by chemotherapy -- not anemia due to other causes in patients with cancer. Erythropoietin treatment does not help prolong survival. In fact, these drugs can shorten survival time and cause tumors to grow faster. Discuss with your doctor whether an erythropoiesis-stimulating drug is appropriate for you.

Survival and tumor growth risks are especially pronounced for patients with advanced breast, head and neck, lymphoid, or non-small cell lung cancer when dosing attempts to achieve a hemoglobin level of 12 g/dL or greater. However, there may be similar risks for patients dosed to less than 12 g/dL. (The American Society of Clinical Oncology and the American Society of Hematology recommend starting erythropoietin when a patient’s hemoglobin level falls to less than 10 g/dL.) The doctor should use the lowest effective dose and erythropoietin treatment should be stopped as soon as the chemotherapy course is completed.

Erythropoiesis-Stimulating Drugs and Chronic Kidney Failure. For patients with chronic kidney failure, the FDA recommends that erythropoiesis-stimulating drugs be used to maintain hemoglobin levels between 10 - 12 g/dL. (The exact level within this range varies by individual.) There is a greater risk of death and serious cardiovascular events, such as heart attack, stroke, and heart failure when these drugs are used to achieve higher hemoglobin levels (13.5 - 14g/dL) compared to lower hemoglobin levels (10- 11.3 g/dL).

Warning Symptoms. Contact your doctor if you experience any of the following symptoms while being treated with an erythropoiesis-stimulating drug:

Pain or swelling in the legs
Worsening in shortness of breath
Increases in blood pressure (be sure to regularly monitor your blood pressure)
Dizziness or loss of consciousness
Extreme fatigue
Blood clots in hemodialysis vascular access ports

H. pylori, the bacteria that cause peptic ulcers, is associated with anemias from vitamin B12 deficiency and iron deficiency. People whose anemia is associated with H. pylori infection, however, do not respond to iron therapy. Studies indicate that the eradication of H. pylori infection with antibiotics can reverse anemia in such patients and may lead to long-lasting recovery.

Vitamin B12 Therapy. Injections of vitamin B12 (usually formulations called cyanocobalamin or hydroxocobalamin), oral folic acid therapy, or both, rapidly reverse the production of abnormally large red blood cells. (Treatments still may not reverse neurologic symptoms if they are extensive or have continued for too long.)

A typical regimen for vitamin B12 replacement is as follows:

If diagnostic tests indicate pernicious anemia and neurologic symptoms are present, vitamin B12 therapy should begin immediately. (Usually vitamin therapy is not an emergency, however.)
Cyanocobalamin or hydroxocobalamin injections are given every day for up to 2 weeks. Only small doses are needed.
This is followed by injections twice a week for another month. (Hemoglobin levels rise in the first week of therapy and reach normal levels in 8 weeks.)
After that, injections are usually given monthly.
During recovery, there is a risk of potassium deficiency as the new red cells take up the existing supply, so potassium supplements may be needed.

Other forms of vitamin B12 are also available and can be used to treat B12 deficiency. Vitamin B12 nasal spray offers the same advantage of avoiding the need for absorbing the vitamin in the GI tract without the inconvenience of the injections. Some experts feel that even oral B12 in high doses (2,000 mcg/day) can maintain B12 levels once the deficiency is treated.

The injections are safe and have no adverse side effects, but they may mask an underlying medical or psychological condition.

Some doctors give vitamin B12 injections for fatigue and other vague symptoms of general mild discomfort. In one study, 10% of patients in a rural clinic were given regular B12 shots, with 6% of patients having no medical need for them.

Folic Acid Treatment. Folate deficiency is easily remedied in 4 - 5 weeks with daily oral doses of 1 - 2 milligrams of folic acid. Many doctors give vitamin B12 along with folic acid unless B12 deficiency is definitely ruled out.

Overview

Procedure
Aftercare

HEALTH GUIDE REFERENCE FROM A.D.A.M

Indications

Forehead lifts are most commonly done for people in their 40s to 60s to slow the visible effects of aging.

In younger people, a forehead lift can raise congenitally low eyebrows that give the face a sad expression. In people whose brows are so low that they interfere with the upper field of vision, the forehead lift can be performed as a reconstructive procedure.

A good forehead lift candidate is someone who has one or more of these facial characteristics: sagging brows, tissue that hangs down at the outer part of the eyelids, horizontal wrinkling on the forehead, or a dysfunctional nose. Deep furrows between the eyes also can be reduced through a forehead lift.

Procedure

Many surgeons used local infiltration anesthesia combined with a sedative, so the patient is awake but sleepy and insensitive to pain. Some patients request a general anesthesia, so they will sleep through the operation.

Sections of hair will be held away from the operative area. Hair immediately in front of the incision line may need to be trimmed but the head will not need to be shaved.

The incision is made at the level of the ears and continues across the top of the forehead at the hairline. This avoids making the forehead appear too high. If the patient is bald or balding, the surgeon may utilize a mid-scalp incision, eliminating a visible scar.

The forehead skin is elevated and measured for removal of excess tissue, skin, and muscle. The incision is closed with stitches or staples.

Aftercare

The operative area is wrapped with a sterile padding and an elastic bandage to inhibit bleeding and edema. There will likely be numbness and temporary discomfort around the surgical site. These symptoms are easily controlled with medication.

The head should be elevated for two to three days after surgery to inhibit swelling. Bruising and swelling is inevitable around the eyes and cheeks, but this begins to disappear in about a week.

As the nerves regenerate, numbness of the forehead and scalp will soon be replaced with itching. It may take up to six months for these sensations to fully disappear. The bandages will be removed a day or two after surgery. Within 10 to 14 days, the stitches or clips will be removed.

Forehead lift - series

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

A forehead lift is a surgical procedure to correct sagging of the forehead skin, eyebrows, and upper eyelids.

Alternative Names

Endobrow lift; Open browlift; Temporal lift

Description

A forehead lift removes or alters the muscles and skin that cause such visible signs of aging as drooping eyebrows, "hooding" eyelids, forehead furrows, and frown lines. The surgery may be done alone or with other procedures such as a facelift, eyelid surgery, or nose reshaping. The surgery can be done in a surgeon's office, an outpatient surgery center, or a hospital. It's usually done on an outpatient basis, without an overnight stay.

You will be awake, but will be given local anesthesia so that you won't feel pain. You might also get a sedative to relieve anxiety. During the procedure, you will feel some stretching of the forehead skin and possibly occasional discomfort. Some patients ask for general anesthesia so they will sleep through the operation.

Sections of hair will be held away from the surgery area. Hair immediately in front of the incision line may need to be trimmed, but your head will not be shaved. The doctor will make the incision at ear level and continue it across the top of the forehead at the hairline to avoid making the forehead appear too high. If you are bald or balding, the surgeon may use a mid-scalp incision to avoid a visible scar.

After removing excess tissue, skin, and muscle, the doctor will close the incision with stitches or staples. Before dressings are applied, your hair and face will be washed to prevent irritation to the scalp skin.

Indications

This procedure is most commonly done on people in their 40s - 60s to slow the visible effects of aging. It can also help people with inherited conditions, such as furrowed lines above the nose or a droopy eyebrow.

In younger people, a forehead lift can raise low eyebrows that give the face a "sad" expression. In people whose brows are so low that they interfere with the upper part of their vision, the forehead lift can be done as a reconstructive procedure.

A good candidate for a forehead lift has one or more of the following:

Deep furrows between the eyes
Horizontal wrinkles on the forehead
Nose that doesn't function properly
Sagging brows
Tissue that hangs down at the outer part of the eyelids

Risks

Occasionally, forehead lifts will make it difficult to raise the eyebrows or wrinkle the forehead on one or both sides. If this happens, you might need more surgery to make both sides even. If you have already had plastic surgery to lift your upper eyelids, a forehead lift is not recommended because it could limit closing the eyelids.

In most people, the incision for the forehead lift is underneath the hairline. If you have a high or receding hairline, you may be able to see a thin scar after surgery, and you'll need to style your hair so that it partially covers your forehead.

If the forehead skin is pulled too tightly or there is excessive swelling, a broad scar may form. In some cases hair loss may occur along the scar edges. This can be treated by surgically removing the scar tissue or areas of hair loss so a new scar can form. Permanent hair loss after a forehead lift is rare.

Medical conditions that could cause problems during or after surgery:

Blood clotting problems
Smoking
Tendency to form excessive scars
Uncontrolled high blood pressure

Expectations after surgery

The area is wrapped with a sterile padding and an elastic bandage to prevent bleeding and edema. You will feel numbness and temporary discomfort in the surgical site, which you can control with medication.

You'll keep your head raised for 2 - 3 days after surgery to prevent swelling. Bruising and swelling will occur around the eyes and cheeks, but should begin to disappear in a few days or a week.

As nerves regrow, numbness of the forehead and scalp will be replaced with itching. It may take up to 6 months for these sensations to fully disappear. The bandages will be removed a day or two after surgery. Within 10 -14 days, the stitches or clips will be removed in 2 stages.

Convalescence

You will be able to walk around in 1 - 2 days, but you won't be able to work for at least 7 days after surgery. You can shampoo and shower 2 days after surgery, or as soon as the bandages are removed.

Within 10 days, you should be able to go back to work or school. You should limit vigorous physical activity (jogging, bending, heavy housework, sex, or any activity that increases your blood pressure) for several weeks. Avoid contact sports for 6 - 8 weeks. Limit prolonged exposure to heat or sun for several months.

Hair shafts will be a bit thinner around the incision for a few weeks or months, but the hair should start to grow normally again. Wearing your hair down on your forehead will hide most scars.

Most signs of the surgery should fade completely within 2 - 3 months. Makeup can cover minor swelling and bruising. At first, you'll probably feel tired and let down, but that will pass as you begin to look and feel better.

Most patients are pleased with the results of a forehead lift, and appear much younger and more rested than they did before. The procedure minimizes the appearance of aging for years. Even if you don't have the surgery repeated in later years, you will probably look better than if you had never had a forehead lift.
