Bulimia nervosa is characterized by which feature?

• A. Binge eating with compensatory behaviors
• B. Persistent restriction leading to underweight
• C. Lack of concern about weight
• D. No weight concerns

Answer: (A)

The defining feature is binge eating episodes followed by compensatory behaviors to prevent weight gain. This binge–purge cycle, often tied to preoccupation with body shape and weight, is what sets bulimia nervosa apart from other eating disorders. People with bulimia may have a normal or slightly higher body weight, contrasting with anorexia nervosa, which centers on restrictive intake leading to underweight. Choices describing persistent restriction or no weight concerns don’t fit bulimia’s pattern of weight-related preoccupation with repeated bingeing and compensatory actions.
