Binge eating disorder is a condition that probably affects millions of Americans. People with binge eating disorder frequently eat large amounts of food while feeling a loss of control over their eating. This disorder is different from binge-purge syndrome (bulimia nervosa) because people with binge eating disorder usually do not purge afterward by vomiting or using laxatives.

How Does Someone Know if He or She Has Binge Eating Disorder?

Binge Eating Symptoms
Most of us overeat from time to time, and many people feel they frequently eat more than they should. Eating large amounts of food, however, does not mean that a person has binge eating disorder. Doctors are still debating the best ways to determine if someone has binge eating disorder. But most people with serious binge eating problems have:

• Frequent episodes of eating what others would consider an abnormally large amount of food.
• Frequent feelings of being unable to control what or how much is being eaten.
• Several of these behaviors or feelings:
  1. Eating much more rapidly than usual.
  2. Eating until uncomfortably full.
  3. Eating large amounts of food, even when not physically hungry.
  4. Eating alone out of embarrassment at the quantity of food being eaten.
  5. Feelings of disgust, depression, or guilt after overeating.

Episodes of binge eating also occur in the eating disorder bulimia nervosa. Persons with bulimia, however, regularly purge, fast, or engage in strenuous exercise after an episode of binge eating. Purging means vomiting or using diuretics (water pills) or laxatives in greater-than-recommended doses to avoid gaining weight. Fasting is not eating for at least 24 hours. Strenuous exercise, in this case, is defined as exercising for more than an hour solely to avoid gaining weight after binge eating. Purging, fasting, and strenuous exercise are dangerous ways to attempt weight control.

How Common is Binge Eating Disorder, and Who is at Risk?

Binge Eating Risks
Although it has only recently been recognized as a distinct condition, binge eating disorder is probably the most common eating disorder. Most people with binge eating disorder are obese (more than 20 percent above a healthy body weight), but normal-weight people also can be affected. Binge eating disorder probably affects 2 percent of all adults, or about 1 million to 2 million Americans. Among mildly obese people in self-help or commercial weight loss programs, 10 to 15 percent have binge eating disorder. The disorder is even more common in those with severe obesity.

Binge eating disorder is slightly more common in women, with three women affected for every two men. The disorder affects blacks as often as whites; its frequency in other ethnic groups is not yet known. Obese people with binge eating disorder often became overweight at a younger age than those without the disorder. They also may have more frequent episodes of losing and regaining weight (yo-yo dieting).

What Causes Binge Eating Disorder?

Binge Eating Causes
The causes of binge eating disorder are still unknown. Up to half of all people with binge eating disorder have a history of depression. Whether depression is a cause or effect of binge eating disorder is unclear. It may be unrelated. Many people report that anger, sadness, boredom, anxiety or other negative emotions can trigger a binge episode. Impulsive behavior and certain other psychological problems may be more common in people with binge eating disorder.

Researchers also are looking into how brain chemicals and metabolism (the way the body burns calories) affect binge eating disorder. These areas of research are still in the early stages.
