Anorexia nervosa

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

HEALTH GUIDE REFERENCE FROM A.D.A.M

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

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

There are two main types of anorexia nervosa:

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

Signs and Symptoms

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

Physical Signs

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

Psychological Signs

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

Behavioral Symptoms

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

Causes

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

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

Risk Factors

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

Diagnosis

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

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

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

Preventive Care

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

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

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

Treatment

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

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

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

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

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

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

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

Lifestyle

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

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

Medications

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

Serotonin Reuptake Inhibitors

Fluoxetine

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

Tricyclic Antidepressants

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

Clomipramine

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

Antihistamines

Cyproheptadine

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

Hormones

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

Nutrition and Dietary Supplements

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

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

Following these nutritional tips may help reduce symptoms:

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

You may address nutritional deficiencies with the following supplements:

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

Herbs

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

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

Massage and Physical Therapy

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

Homeopathy

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

Mind-Body Medicine

Cognitive Behavioral Therapy

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

Family Therapy

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

Hypnosis

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

Biofeedback

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

Other Considerations

Pregnancy

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

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

Prognosis and Complications

Medical complications associated with anorexia include:

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

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

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

Nephrotic syndrome is a group of symptoms including protein in the urine (more than 3.5 grams per day), low blood protein levels, high cholesterol levels, and swelling. The urine may also contain fat, which can be seen under the microscope.

Alternative Names

Nephrosis

Causes, incidence, and risk factors

Nephrotic syndrome is caused by various disorders that damage the kidneys, particularly the basement membrane of the glomerulus. This immediately causes abnormal excretion of protein in the urine.

The most common cause in children is minimal change disease, while membranous glomerulonephritis is the most common cause in adults.

This condition can also occur as a result of infection, use of certain drugs, cancer, genetic disorders, immune disorders, or diseases that affect multiple body systems including diabetes, systemic lupus erythematosus, multiple myeloma, and amyloidosis.

It can accompany kidney disorders such as glomerulonephritis, focal and segmental glomerulosclerosis, and mesangiocapillary glomerulonephritis.

Nephrotic syndrome can affect all age groups. In children, it is most common from age 2 to 6. This disorder occurs slightly more often in males than females.

Symptoms

Swelling (edema )
- general
- around the eyes
- in the extremities, especially the feet and ankles
Swollen abdomen
Facial swelling
Foamy appearance of the urine
Weight gain (unintentional) from fluid retention
Poor appetite
High blood pressure

Signs and tests

Physical examination can detect some symptoms. Other symptoms and signs of causative disorders can also be found with examination.

Urinalysis reveals large amounts of urine protein. Fats are often also present in the urine.

Tests to rule out various causes may include the following:

This disease may also alter the results of the following tests:

Treatment

The goals of treatment are to relieve symptoms, prevent complications and delay progressive kidney damage. Treatment of the causative disorder is necessary to control nephrotic syndrome. Treatment may be required for life.

Corticosteroid, immunosuppressive, antihypertensive, and diuretic medications may help control symptoms. Antibiotics may be needed to control infections. Angiotensin converting enzyme (ACE) inhibitors may significantly reduce the degree of protein loss in the urine and are therefore frequently prescribed for treatment of nephrotic syndrome.

If hypertension occurs, it must be treated vigorously. Treatment of high blood cholesterol and triglyceride levels is also recommended to reduce the risk of atherosclerosis. Dietary limitation of cholesterol and saturated fats may be of little benefit, as the high levels which accompany this condition seem to be the result of overproduction by the liver rather than from excessive fat intake. Medications to reduce cholesterol and triglycerides may be recommended.

High-protein diets are of debatable value. In many patients, reducing the amount of protein in the diet produces a decrease in urine protein. In most cases, a moderate-protein diet (1 gram of protein per kilogram of body weight per day) is usually recommended. Sodium (salt) may be restricted to help control swelling. Vitamin D may need to be replaced if nephrotic syndrome is chronic and unresponsive to therapy.

Blood thinners may be required to treat or prevent clot formation.

Expectations (prognosis)

The outcome varies; the syndrome may be acute and short-term or chronic and unresponsive to therapy. The cause and development of complications also affects the outcome.

Complications

Atherosclerosis and related heart diseases
Renal vein thrombosis
Acute renal failure
Chronic renal failure
Infections, including pneumococcal pneumonia
Malnutrition
Fluid overload, congestive heart failure, pulmonary edema

Calling your health care provider

Call your health care provider if symptoms which may indicate nephrotic syndrome occur.

Call your health care provider if nephrotic syndrome persists or if new symptoms develop, including severe headache, fever, sores on the skin, cough, discomfort with urination, or decreased urine output.

Go to the emergency room or call the local emergency number (such as 911) if convulsions occur.

Prevention

Treatment of causative disorders may prevent development of nephrotic syndrome.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

Focal segmental glomerulosclerosis is scar tissue that forms in areas of the kidney that filter certain things out of the body. These areas are called glomeruli. The help the body get rid of harmful or unnecessary substances. Each kidney has thousands of glomeruli.

"Focal" means that some of the glomeruli become scarred, while others remain normal. "Segmental" means that only part of an individual glomerulus is damaged.

Alternative Names

Segmental glomerulosclerosis; Focal sclerosis with hyalinosis

Causes, incidence, and risk factors

The cause of focal segmental glomerulosclerosis is usually unknown. A small number of cases result from reflux nephropathy. The condition affects both children and adults. Males are affected slightly more often than females, and it also occurs more frequently in African Americans.

Focal segmental glomerulosclerosis causes about 10 - 15% of all cases of nephrotic syndrome.

Symptoms

Foamy urine
Swelling of the body, called generalized edema, from retained fluids
Weight gain
Poor appetite

Signs and tests

There are no strong clues to the diagnosis on physical examination, other than evidence of edema and elevated blood pressure. Signs of kidney renal failure and associated fluid overload may develop as the illness gets worse.

Tests may include:

Urinalysis
Kidney biopsy
Immunofluorescence microscopy test

Treatment

The goal of treatment is to control the symptoms associated with nephrotic syndrome and chronic kidney failure. For detailed treatment information for those conditions, see:

In general, treatments may include:

Low or moderate protein diet (1 gram of protein per kilogram of body weight per day)
Low fat diet
Salt-free diet
Fluid restriction
Powerful anti-inflammatory medicines to reduce the immune response
Medicines to treat high blood pressure, high blood cholesterol, and high triglyceride levels
Antibiotics to control infections
Vitamin D supplementation
Dialysis
Kidney transplantation

Expectations (prognosis)

Over half of all persons with focal or segmental glomerulosclerosis develop chronic kidney failure within 10 years.

Complications

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

Membranous nephropathy is a kidney disorder which involves changes and inflammation of the structures inside the kidney that help filter waste and fluids. The inflammation leads to problems with kidney function.

Alternative Names

Membranous glomerulonephritis; Membranous GN; Extramembranous glomerulonephritis; Glomerulonephritis - membranous

Causes, incidence, and risk factors

Membranous nephropathy is caused by thickening of part of the glomerular basement membrane. Glomerular basement membrane is a part of the kidneys that helps filter waste and extra fluid from the blood. The exact reason for this thickening is not known.

It is one of the most common causes of nephrotic syndrome. The condition may be a primary kidney disease of uncertain origin, or it may be associated with other conditions.

The following increase your risk for this condition:

Exposure to substances or medications, including gold, mercury, penicillamine, trimethadione, and skin-lightening creams
Hepatitis B
Malaria
Non-Hodgkin's lymphoma
Solid cancerous tumors
Systemic lupus erythematosus
Syphilis

The disorder occurs in approximately 2 out of 10,000 people. It may occur at any age but is more common after age 40.

Symptoms

Edema (swelling) in any area of the body
Foamy appearance of urine
Weight gain
Poor appetite
Urination, excessive at night
High blood pressure

Note: Symptoms vary and in many cases there are no symptoms at all.

Signs and tests

A physical exam may show swelling (edema).

A urinalysis may reveal protein in the urine or blood in the urine. Glomerular filtration rate (the "speed" of blood purification) is usually nearly normal.

Serum albumin may be low. Blood lipid levels may increase.

Kidney biopsy confirms the diagnosis of membranous nephropathy.

Treatment

The goal of treatment is to reduce symptoms and slow the progression of the disease.

Symptoms should be treated as appropriate. Medications vary and may include corticosteroids, immunosuppressive drugs, blood pressure medications, and antibiotics (to control infections).

High blood cholesterol and triglyceride levels should be treated to reduce the risk of atherosclerosis secondary to nephrotic syndrome. A low-fat, low-cholesterol diet may be of limited benefit as the high levels of cholesterol and triglyceride seem to be caused by overproduction by the liver rather than eating too much fat. Medications to reduce cholesterol and triglycerides may be recommended.

The value of a high-protein diets has been debated. In many patients, reducing the amount of protein in the diet produces decrease in protein in the urine. In most cases, a moderate-protein diet (1 gram of protein per kilogram of body weight per day) is usually recommended.

Restricting salt may be help control edema. Vitamin D may need to be replaced if nephrotic syndrome is chronic and does not respond to therapy.

This disease increases the risk for blood clots in the lungs and legs.Patients are occasionally prescribed blood thinners to prevent these complications.

Expectations (prognosis)

The outlook varies. There may be symptom-free periods and acute flare ups. In some cases, the condition may go away with or without therapy.

The majority of patients will have some degree of irreversible kidney damage within 2-20 years. About 20% of those will progress to end-stage renal disease.

Complications

Calling your health care provider

Call for an appointment with your health care provider if symptoms indicate membranous nephropathy may be present. Call for an appointment with your health care provider if symptoms worsen or persist, if you experience a decreased urine output or other new symptom develops.

Prevention

Promptly treating associated disorders and avoiding associated substances may reduce risk.

Surprising Findings on Women's Eating Behaviors

FitSugar — Thu, 24 Apr 2008 03:00:00 -0700

According to the results of a new survey by Self Magazine in partnership with the University of North Carolina at Chapel Hill, the majority of American women have troubling relationships with food. According to a detailed survey of over 4,000 women, 65 percent of respondents between the ages of 25 and 45 report having disordered eating behaviors. Here are highlights from the interesting findings:

75 percent of women report disordered eating behaviors or symptoms consistent with eating disorders
67 percent of women (excluding those with actual eating disorders) are trying to lose weight
53 percent of dieters are already at a healthy weight and are still trying to lose weight

There are more interesting stats so read more.

39 percent of women say concerns about what they eat or weigh interfere with their happiness
37 percent regularly skip meals to try to lose weight
27 percent would be “extremely upset” if they gained just five pounds
26 percent cut out entire food groups
16 percent have dieted on 1,000 calories a day or fewer
13 percent smoke to lose weight
12 percent often eat when they’re not hungry; 49 percent sometimes do

Some of these statistics surprise me while others seem about right. In the end I am saddened by these findings. As women we are brought through the wringer when it comes to body image and eating that it's hard to just be content with who you are. What about you guys? How do you feel about any of the above findings? Do they seem extreme or right on track?

You Asked: Ways to Get High Blood Pressure Under Control

FitSugar — Fri, 04 May 2007 13:30:00 -0700

Did you know that while most Americans with high blood pressure are taking steps to combat the potentially deadly condition, only 30 percent have it under control?

If you or someone you love has hypertension, there are several steps you can take to help keep it under control:

Try the D.A.S.H. eating plan: DASH stands for Dietary Approaches to Stop Hypertension and it is an eating plan that emphasizes fruits, vegetables, and lowfat dairy foods. It is low in saturated fat, total fat and cholesterol. The DASH eating plan includes whole grains, poultry, fish, and nuts and has reduced amounts of fats, red meats, sweets, and sugared beverages.
Exercise: Get started by doing 30 minutes of a moderate-level activity on most, and preferably all, days of the week. Brisk walking, bicycling, and gardening are examples. You can even divide the 30 minutes into shorter periods of at least 10 minutes each.
Reduce Salt intake: For someone with high blood pressure, the doctor may advise eating less salt and sodium, as recent research has shown that people consuming diets of 1,500 mg of sodium (that's a little more than 1/2 teaspoon of salt) had even better blood pressure lowering benefits.
Lay off the Booze: If you drink alcoholic beverages, have only a moderate amount - one drink a day for women; two drinks a day for men.
Smoking: DON'T SMOKE. If you do, QUIT!
Lose the extra LBS: Being overweight increases your risk of developing high blood pressure. In fact, blood pressure rises as body weight increases. Losing even 10 pounds can lower blood pressure - and it has the greatest effect for those who are overweight and already have hypertension.
Medicate: Your doctor can prescribe a medication to lower your blood pressure, especially if you're doing everything listed above but still can't control hypertension.

The Incredible, Edible Egg Now Helps With Weight Loss

FitSugar — Tue, 01 May 2007 09:30:00 -0700

Here's a reason to get up just a little bit earlier to fix yourself some eggs tomorrow...

A new study presented at Experimental Biology 2007 has found that eggs, when eaten for breakfast, can help a dieter lose weight. Even more than that, the study found that overweight women who ate two eggs for breakfast at least five days a week for 8 weeks (as part of a low-fat diet with a 1,000 calorie reduction): Lost 65 percent more weight, had 83 percent greater reductions in waist circumference and reported greater improvements in energy levels than their dieting counterparts who consumed a bagel breakfast of the same calories. Personally, I was sitting here saying well of course because a bagel has a whole lot more calories than an egg, however in the study, the egg and bagel breakfasts not only provided the same amount of calories, but also the same weight mass. Now I am convinced.

Fit's Tip: Worried that eggs will raise your cholesterol? Then think about switching to Omega-3 eggs.
