Question

which eating disorder is best characterized by eating large amounts of food at one sitting and then purging?
○ bulimia nervosa
○ anorexia nervosa
○ binge-eating disorder
○ orthorexia

Explanation:

Bulimia nervosa is defined by recurrent episodes of binge-eating (consuming large amounts of food in a short time) followed by compensatory purging behaviors (such as vomiting, laxative use) to avoid weight gain. Anorexia nervosa primarily involves extreme restriction of food intake and fear of weight gain without binge-purge cycles as the defining trait. Binge-eating disorder involves binge-eating without compensatory purging. Orthorexia is an obsession with "healthy" eating, not bingeing and purging.

Answer:

bulimia nervosa
