Which disorder includes cycles of excessive eating followed by attempts to remove the calories consumed?

The disorder characterized by cycles of excessive eating, known as binge eating, followed by behaviors aimed at preventing weight gain—such as self-induced vomiting, excessive exercise, or fasting—is Bulimia nervosa. Individuals with bulimia often experience a loss of control during binges and subsequent feelings of guilt or shame, leading to these compensatory behaviors. This disorder is distinguished from others as it involves this specific cycle of bingeing and purging.

Muscle dysmorphia is primarily focused on an obsessive concern with muscle size and body composition rather than the eating and compensatory behavior associated with bulimia. Anorexia nervosa involves extreme self-starvation and an intense fear of gaining weight, but it does not typically include the binge-purge cycle. Orthorexia pertains to an unhealthy obsession with eating foods that one considers healthy, lacking the binge-eating episodes that define bulimia. Thus, the identification of bulimia nervosa as the disorder in question is based on its unique pattern of eating behavior and compensatory actions.
