**Core Concept**
Anorexia nervosa and bulimia nervosa are two distinct eating disorders characterized by abnormal eating habits and body image concerns. Anorexia nervosa is primarily defined by restrictive eating patterns and a significant weight loss, whereas bulimia nervosa involves recurrent episodes of binge eating followed by compensatory behaviors such as self-induced vomiting or laxative abuse.
**Why the Correct Answer is Right**
The key distinguishing feature between anorexia nervosa and bulimia nervosa lies in the presence of binge eating episodes in bulimia nervosa. Individuals with anorexia nervosa typically restrict their food intake and have a fear of gaining weight, whereas those with bulimia nervosa engage in episodes of excessive food consumption followed by purging behaviors to compensate for the caloric intake. The binge-purge pattern in bulimia nervosa is a critical diagnostic criterion that differentiates it from anorexia nervosa.
