Criteria

Bulimia criteria according to DSM

  • (1) eating, in a discrete period of time (e.g. within any 2 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 (e.g. a feeling that one cannot stop eating or control what or how much one is eating)
B. Recurrent inappropriate compensatory behaviour in order to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, enemas or other medications; fasting; or excessive exercise.
C. The binge eating and inappropriate compensatory behaviours both occur, on average, at least once a week for 3 months.
D. Self-evaluation is unduly influenced by body shape and weight.
E. The disturbance does not occur exclusively during episodes of Anorexia Nervosa.

Specify type:

Purging Type: During the current episode of Bulimia Nervosa, the person has regularly engaged in self-induced vomiting or the misuse of laxatives, diuretics or enemas.

Non-purging Type: During the current episode of Bulimia Nervosa, the person has used other inappropriate compensatory behaviours, such as fasting or excessive exercise, but has not regularly engaged in self-induced vomiting or the misuse of laxatives, diuretics or enemas.




Anorexia criteria according to DSM.


A. Not maintaining a weight healthy for their height and age. Restricting energy intake leading to a significantly low body weight.
B. Intense fear of gaining weight or becoming fat, even though underweight.
C. 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.

Binge Eating Disorder Criteria according to DSM

BED is defined as having "a sense of lack of control over eating" with the person suffering also exhibiting three or more of the following:
  • Eating much more rapidly than normal.
  • Eating until feeling uncomfortably full.
  • Eating large amounts of food when not feeling physically hungry.
  • Eating alone because of feeling embarrassed by how much one is eating.
  • Feeling disgusted with oneself, depressed or very guilty afterward.






EDNOS (Eating Disorder Not Otherwise Specified) criteria according to the DSM.

If some but not all the criteria are met for one of the other three disorders (anorexia, bulimia, binge eating disorder), the diagnosis is EDNOS.

- All the criteria for Anorexia Nervosa are met except that, despite significant weight loss, the individual’s current weight is in the normal range or above.
-All the criteria for Bulimia Nervosa are met except that the binge eating and inappropriate compensatory mechanisms occur at a frequency of less than once a week or for a duration of less than 3 months.
- The regular use of inappropriate compensatory behaviour by an individual of normal body weight after eating small amounts of food (e.g. self-induced vomiting after the consumption of two biscuits.
-Repeatedly chewing and spitting out, but not swallowing, large amounts of food.
