Eating disorders are complex conditions involving psychological factors and nutritional deficiencies. The
term eating disorders includes anorexia nervosa, bulimia, and binge-eating.
The psychological factors may include an inability to cope with stress, problems with family and other
relationships, feelings of deprivation, and experiences of physical, sexual, or emotional abuse.
Psychotherapy is an essential part of the treatment for eating disorders, along with nutrition counseling and
medical care as needed.1
A person with anorexia does not eat enough to maintain a healthy weight; she views herself as overweight
and is anxious about gaining weight. Anorexia typically begins in early adolescence, mainly among girls,
though the numbers of boys developing this condition is increasing. People with anorexia weigh less than 85%
of the normal weight for their age and height. Excessive exercise, vomiting, and abuse of laxatives and/or diuretics may also occur. Severe anorexia can be life threatening.
Bulimia, also known as bingeing and purging, is more common than anorexia, and usually affects teenage
girls and women in their twenties. It involves a recurring, emotionally driven cycle of compulsive
consumption of large quantities of high-calorie food in a short period of time, followed by induced vomiting.
Some individuals also use laxatives, drugs that induce vomiting, diuretics, or excessive exercise in an
attempt to purge. About 50% of anorexics also purge, and both bulimia and anorexia can coexist in the same
person.2 Unlike those with anorexia,
some people affected by bulimia maintain normal or even excessive body weight.
Binge-eating disorder is similar to bulimia but no purging is done. It is more common than either bulimia
or anorexia nervosa, and people with binge-eating disorder are usually overweight.3
People with eating disorders may have a preoccupation with weight and food, anxiety about their body image, and/or a feeling that they lose control over how much they eat. They may also exercise compulsively and, in women, experience missed menstrual periods. They may also frequently use laxatives, diet pills, and medicines designed to induce vomiting or reduce fluid retention.
Although regular, moderate exercise offers important health benefits, for many people excessive exercise is a common component of eating disorders, especially anorexia nervosa.4 In one controlled trial, a majority of the people with eating disorders reported that participation in competitive sports and exercise performed as part of a weight loss plan contributed to their condition.5 For people with eating disorders, it is important to establish and maintain healthy exercise habits; these individuals should consult with a healthcare professional skilled in eating disorders.
Psychological counseling, for both the individual and her family, and behavior modification training are also commonly used for people with eating disorders, often as part of a team approach that also includes nutrition counseling and medical care. Numerous preliminary and controlled studies have shown that the psychotherapy technique known as cognitive-behavioral therapy is effective in reducing the symptoms of bulimia.6, 7 For example, one study found 69% of a group receiving cognitive-behavioral therapy were abstaining from binge-eating and purging six months later compared to only 15% of a group keeping a diary of their behavior.8 Preliminary studies9 and one controlled trial10 suggest another technique, interpersonal psychotherapy, is equally effective for people with bulimia. Cognitive behavioral therapy and interpersonal psychotherapy have also been effective for people with binge-eating disorder in controlled trials,11, 12 resulting in cessation of binge-eating in almost half of the subjects in one report.13
The effectiveness of psychotherapy for anorexia nervosa is less clear.14, 15 One controlled trial found that psychotherapy (type unspecified) significantly improved weight gain compared to no treatment, and complete or nearly complete recovery occurred in 60% of the patients.16 Two other studies comparing different types of psychotherapy for anorexia nervosa found comparable improvement from all types;17, 18 one of these studies reported moderate improvement in 63% of cases.19 Long-term effectiveness of psychotherapy for eating disorders has not been studied.
Individuals with both bulimia and anorexia are likely to report a craving for sugar; people with bulimia eat more sweets and carbohydrates, particularly during binges, than do healthy individuals. In a double-blind study, bulimic subjects were reported to have significantly more mood changes after receiving glucose (corn sugar) injections compared to placebo injections. Preliminary evidence suggests that purging results in low blood sugar, which might increase the incidence of repeated bingeing and purging by stimulating appetite or altering mood.
The most important dietary change for people with eating disorders is to eat a sufficient amount of calories without purging. To accomplish this, most will need psychological as well as nutrition counseling.
Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by some in the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 StarsReliable and relatively consistent scientific data showing a substantial health benefit.
2 StarsContradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 StarFor an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
People with eating disorders who restrict their food intake are at risk for multiple nutrient deficiencies, including protein, calcium, iron, riboflavin, niacin,folic acid,vitamin A, vitamin C, and vitamin B6, and essential fatty acids. A general multivitamin-mineral formula can reduce the detrimental health effects of these deficiencies.
A serotonin precursor, 5-HTP (5-hydroxytryptophan), has been shown to reduce appetite in weight-control and diabetes trials. However, what effect 5-HTP has, if any, on people with binge eating disorder, bulimia, or anorexia is unknown. Unlike L-tryptophan, 5-HTP is available from health food stores and some pharmacies without prescription.
