On questioning, he reveals that he has a habit of binge eating during times of stress, particularly during exams. He then feels guilty about his behavior and attempts to compensate by going to the gym, sometimes for 4 hours per day. He is disturbed by this behavior and feels out of control. He denies ever vomiting as a means of loosing weight. What is the most likely diagnosis?? A: Anorexia nervosa, B: Bulimia nervosa, C: Normal behavior variant, D: Hypomania, E: Body dysmorphic disorder,  <response>: This is a question about diagnosing an eating disorder in an 18-year-old male based on his history and physical exam findings. The key details in the stem are his binge eating during times of stress followed by excessive exercise, feelings of guilt, and feeling out of control. These point towards a likely diagnosis of bulimia nervosa. Anorexia nervosa is less likely given the lack of restricted food intake or low weight. The behavior does not seem like normal variant or hypomania. Body dysmorphic disorder is focused on preoccupation with perceived flaws in appearance rather than an eating disorder.B: Bulimia nervosa
