"In 30 patients whose illness bears a close resemblance to anorexia nervosa,…episodes of overeating constituted the most constant feature of the disorder…. Overeating was often overshadowed by more dramatic clinical phenomena--intractable self-induced vomiting or purgation…. The constancy and significance of overeating invite a new terminology for description of this symptom--bulimia nervosa." - Gerald F.M. Russell, 1979

The condition might get severe with huge quantities of food being consumed.

To prevent weight gain patients resort to self-induced vomiting, abuse of laxatives, fasting or extremely rigorous exercising.
