Bulimia Nervosa
Diagnosis
A person must display:
1) Recurrent episodes of binge eating. An episode of binge eating is characterised by both of the following:
a. 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.
b. 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).
2) Recurrent inappropriate compensatory behaviour in order to prevent weight gain, such as self-induced vomiting, misuse of laxatives, diuretics, or other medications, fasting, or excessive exercise.
3) The binge eating and inappropriate compensatory behaviours both occur, on average, at least once 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.
