Eating disorder, mostly in women, in which excessive concern with weight and body shape leads to binge eating followed by compensatory behaviour such as self-induced vomiting or the excessive use of laxatives or diuretics. The disorder typically begins in adolescence or early adulthood and is associated with depression, anxiety, and low self-esteem. Bulimia can have serious medical complications such as dental decay and dehydration. Treatment may include psychotherapy. Unlike persons with anorexia nervosa, most bulimics remain close to their proper weight.
