What are the DSM-5-TR criteria for bulimia nervosa?

• A. Purging after meals only on occasion, not binge episodes.
• B. Recurrent binge eating with episodes of inadequacy and compensatory behaviors at least once a week for 3 months; self-evaluation unduly influenced by body shape and weight; does not meet anorexia.
• C. Exclusively excessive exercise without binge eating.
• D. Recurrent vomiting daily for one year.

Answer: (B)

Bulimia nervosa is diagnosed when a person regularly engages in binge eating episodes accompanied by compensatory behaviors to prevent weight gain. A binge involves eating an unusually large amount of food in a discrete period with a sense of loss of control. This pattern must occur at least once a week for three months. In addition, self-worth is unduly influenced by body shape and weight, and the disturbance is not better explained by anorexia nervosa or another disorder. The option that aligns with these criteria describes recurrent binge eating with compensatory behaviors at least weekly for three months, alongside body-weight–related self-evaluation, and notes that the pattern is not due to anorexia. The other options miss essential elements: one lacks binge episodes and the required frequency; another describes excessive exercise without bingeing; the last focuses only on vomiting without the binge-eating criterion and duration.
