Ariana, who feels guilty after binge eating and induces vomiting, most likely suffers from what condition?

Ariana's actions, specifically binge eating followed by inducing vomiting, are indicative of bulimia nervosa. This eating disorder is characterized by episodes of binge eating—consuming large quantities of food in a short period—often accompanied by feelings of loss of control. To counteract the effects of binge eating, individuals with bulimia nervosa may engage in compensatory behaviors such as self-induced vomiting, excessive exercise, or the use of laxatives.

The presence of guilt after the binge eating episode aligns with common psychological aspects of bulimia nervosa, where individuals experience distress about their eating habits and body image. This condition often involves a cycle of binge eating and purging to manage weight and alleviate feelings of guilt, making it distinct from other eating disorders.

Other options might describe different aspects of eating behaviors. Anorexia nervosa primarily involves extreme restriction of food intake and an intense fear of gaining weight, while binge eating disorder features episodes of binge eating without the purging behaviors seen in bulimia. Orthorexia focuses on the obsession with healthy eating, which does not involve binge eating or purging behaviors. Therefore, the behaviors and emotional experiences described in the scenario are most accurately captured by the diagnosis of bulimia nervosa.
