Eating Disorders

Definitions

The following diagnostic criteria are adapted from the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders), published and copyrighted by the American Psychiatric Association.

Diagnostic criteria for ANOREXIA NERVOSA

  1. Refusal to maintain body weight at or above a minimally normal weight for age and height; that is, weight loss leading to maintenance of body weight less than 85% of that expected or a BMI of less than 17.5); or failure to make expected weight gain during periods of growth, which leads to body weight less than 85% of that expected.

  2. Intense fear of gaining weight or becoming fat, even though underweight.

  3. Disturbance in the way in which one's body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or denial of the seriousness of the current low body weight.

  4. In postmenarcheal females, amenorrhea, that is, the absence of at least three consecutive menstrual cycles. (A woman is considered to have amenorrhea if her periods occur only following hormone, such as estrogen, administration.)

Diagnostic criteria for BULIMIA NERVOSA

  1. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:

    1. Eating in a discrete period of time (such as, within any two-hour period), an amount of food that is definitely larger than most people would eat during a similar period of time and under similar circumstances.

    2. A sense of lack of control over eating during the episode, that is,a feeling that one cannot stop eating or control what or how much one is eating.

  2. Recurrent inappropriate compensatory behavior in order to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, enemas, or other medications; fasting; or excessive exercise.

  3. The binge eating and inappropriate compensatory behaviors both occur, on average, at least twice a week for three months.

  4. Self-evaluation is unduly influenced by body shape and weight.

  5. The disturbance does not occur exclusively during episodes of Anorexia Nervosa.

Diagnostic criteria for BINGE EATING DISORDER (sometimes referred to as "compulsive overeating")

  1. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:

    1. Eating in a discrete period of time (such as, within any two-hour period), an amount of food that is definitely larger than most people would eat in a similar period of time under similar circumstances.

    2. A sense of lack of control over eating during the episode, that is, feeling that one cannot stop eating or control what or how much one is eating.

  2. The binge-eating episodes are associated with three or more of the following:

    1. Eating much more rapidly than normal.

    2. Eating until feeling uncomfortably full.

    3. Eating large amounts of food when not feeling physically hungry.

    4. Eating alone because embarrassed by how much one is eating.

    5. Feeling disgusted with oneself, depressed, or very guilty after overeating.

  3. Marked distress regarding the binge eating is present.

  4. The binge eating occurs, on average, at least two days a week for six months.

  5. The binge eating is not associated with the regular use of inappropriate compensatory behaviors (such as, purging, fasting, excessive exercise) and does not occur exclusively during the course of Anorexia Nervosa or Bulimia Nervosa.
