  2. Epidemiology
    1. Onset in adolescence or early adulthood
    2. Prevalence: 4-6 per 200 females in U.S. (much more common than anorexia)
    3. Affects women much more than men by ratio of 10-20:1
  3. Risk Factors
    1. Similar personality traits as with Anorexia Nervosa (common to other Eating Disorders)
      1. Perfectionist, high achiever, who values success and external rewards
      2. Food and appearance regulation is under their control
    2. Sexual Assault or sexual abuse

Bulimia (C0006370)

Definition (NCI) A disorder characterized by recurrent episodes of binge-eating over which the individual feels a lack of control; these episodes of binge-eating are followed by recurrent compensatory behavior to prevent weight gain, usually self-induced vomiting. In addition, self-evaluation is unduly influenced by body image.
Definition (PSY) Disorder characterized primarily by binge eating and often accompanied by self-induced vomiting and/or misuse of laxatives.
Definition (MSH) Eating an excess amount of food in a short period of time, as seen in the disorder of BULIMIA NERVOSA. It is caused by an abnormal craving for food, or insatiable hunger also known as "ox hunger".

Binge eating disorder (C0596170)

Definition (MSH) A disorder associated with three or more of the following: eating until feeling uncomfortably full; eating large amounts of food when not physically hungry; eating much more rapidly than normal; eating alone due to embarrassment; feeling of disgust, DEPRESSION, or guilt after overeating. Criteria includes occurrence on average, at least 2 days a week for 6 months. The binge eating is not associated with the regular use of inappropriate compensatory behavior (i.e. purging, excessive exercise, etc.) and does not co-occur exclusively with BULIMIA NERVOSA or ANOREXIA NERVOSA. (From DSM-IV, 1994)
Definition (NCI) A disorder characterized by recurrent episodes of binge-eating over which the individual feels a lack of control and a sense of disgust and shame; unlike bulimia, however, there is no attempt to compensate for the binge-eating through vomiting or fasting.
Definition (PSY) Eating excessive quantities of food, often after stressful events. Compare BULIMIA.
Definition (CSP) episodes of binge eating with a sense of lack of control; most individuals exhibiting this behavior are obese and usually do not use compensatory behaviors (such as purging, fasting, misuse of laxatives and other medications, or excessive exercise) that are characteristic of bulimia nervosa.
