An eating disorder defined by binge eating followed by compensatory behaviors such as vomiting or excessive exercise.

• A. Anorexia nervosa
• B. Bulimia nervosa
• C. Binge-eating disorder
• D. Avoidant personality disorder

Answer: (B)

This item centers on bulimia nervosa, which is defined by recurrent binge eating episodes followed by compensatory behaviors to prevent weight gain, such as self-induced vomiting or excessive exercise. The crucial idea is that after a binge, the person engages in actions aimed at offsetting the calories consumed, distinguishing bulimia from other eating patterns. Binge-eating disorder involves binge eating without regular compensatory behaviors, so the pattern differs. Anorexia nervosa focuses on severe dietary restriction leading to very low body weight (though some individuals may engage in purge behaviors, the defining feature is underweight from restriction). Avoidant personality disorder is not about eating patterns at all.
