The DSM-IV lists criteria for diagnosing bulimia nervosa. It lists five criteria, the first of which is recurrent episodes of binge eating. The second of which states that the person practices recurrent compensatory behaviors to prevent weight gain, which could include inducing vomiting, using laxatives, or excessive exercise. It also states that these behaviors should occur at least twice a week for three months. I have attached a link to the definition.
The medical criteria that establish the bulimia nervosa diagnostic are stated as:
- the quantity of food ingested in a short period of time is much more larger than in most of the people.
- the patients claim that when they are eating, they are loosing control of themselves; becoming impossible to stop from eating.
- after eating, the fear of gaining weight, make the patients to behave inappropiate. Most of the time, they are taking laxativesand diuretics, they are making enemas or they are self-inducing vomiting episodes.
- if these complete episodes: eating-compensatory behavior occur more than twice a week, for at least 3 months, then diagnosis is bulimia nervosa.
