Which eating disorder is characterized by cycles of binge eating followed by purging or fasting?

• A. Anorexia nervosa
• B. Bulimia nervosa
• C. Sleep Disorders
• D. Paraphilias

Answer: (B)

Bulimia nervosa is defined by recurrent binge eating episodes followed by efforts to counteract weight gain, such as purging (vomiting, laxatives, or diuretics) or extreme fasting or dieting. In a binge, there’s an unusually large amount of food eaten with a sense of loss of control. The compensatory behaviors aim to prevent weight gain after these episodes. This pattern often occurs in individuals who may be of normal weight or overweight, which is a distinguishing feature from some other eating disorders that focus more on restrictive intake and weight loss. The other options don’t describe this binge-purge cycle. Sleep disorders involve disruptions in sleep, not eating patterns. Paraphilias are sexual disorders, not eating-related. Anorexia nervosa centers on severe restriction of intake and relentless fear of gaining weight, leading to significant weight loss, rather than the binge-purge cycle described here. Understanding bulimia helps frame how clinicians assess risk, medical complications, and the appropriate treatment approaches, such as cognitive-behavioral therapy, nutritional counseling, and, when appropriate, medical monitoring or pharmacotherapy.
