[Bulimia nervosa--a modern eating disorder].

Bulimia nervosa is characterized by episodes of compulsive eating of large amounts of food that are followed by measures undertaken to avoid weight gain, and an exaggerated concern about one's figure and weight. Bulimic symptomatology comprises a complex of various interacting components such as poor self-esteem, a negative attitude towards one's own body, eating behavior and current conflicts. Treatment must take account of all of these factors, and involves both internistic and psychotherapeutic elements. The severity of the condition, possible comorbidities, and psychosocial criteria are crucial for deciding whether treatment should be on an ambulatory or an inpatient basis.
