Explain the Bulimia Nervosa?

Diagnostic Criteria Bulimia Nervosa patients, unlike those of anorexia nervosa with binge and purge subtype, are typically within the normal weight range, although some may be slightly underweight or overweight. The common complaints are bloating and flatulence (due to excessive gas production), abdominal pain, constipation and nausea.

The patients are secretive about the eating-vomiting episodes so that family and friends do not know about it. Generally, one episode occurs daily. Calorie dense and high carbohydrate foods like ice cream, cold drinks, bread, jam etc. are eaten in large amounts. Bulimia literally means 'ox-hunger' and the term given to the eating pattern is 'dietary chaos'. Patients tend to suffer from dental caries.
