A psychological eating disorder in which one's have episodes of binge eating:

Question

Accepted Answer

The correct option is (2):
Bulimia nervosa is a complex and potentially life-threatening eating disorder that is centrally characterized by a destructive cycle of recurrent episodes of **binge eating** followed by inappropriate compensatory behaviors. Binge eating is defined as consuming an amount of food that is significantly larger than what most people would eat in a similar period, accompanied by a feeling of loss of control over the eating episode. Following a binge, individuals engage in compensatory or 'purging' behaviors, such as self-induced vomiting, misusing laxatives or diuretics, fasting, or excessive exercise, driven by an extreme fear of gaining weight. Therefore, the presence of these distinct and recurrent binge eating episodes makes Bulimia nervosa the correct psychological disorder described in the question.

The incorrect option is (1):
Anorexia nervosa is fundamentally characterized by the persistent **restriction** of energy intake, which leads to a **significantly low body weight**. While there is a 'binge-eating/purging' subtype of Anorexia nervosa, the defining feature that overrides other diagnoses is the presence of a pathologically low body weight. Patients with Bulimia nervosa, in contrast, are typically at a normal weight or overweight, which is the key diagnostic difference. Since the primary criterion for Anorexia nervosa is the low weight resulting from restriction, and not simply the occurrence of binge-eating episodes, it is not the most accurate answer.

The incorrect option is (3):
PICA is a different feeding and eating disorder characterized by the compulsive eating of **non-nutritive, non-food substances** for at least one month. These substances may include things like dirt, clay, ice, or paint chips. This condition does not involve the consumption of abnormally large amounts of *food* (binge eating) with a feeling of loss of control, nor is it necessarily followed by compensatory behaviors aimed at weight loss. Therefore, PICA is unrelated to the binge eating description provided in the question.

The incorrect option is (4):
Purging disorder is an eating disorder that involves recurrent compensatory behaviors, such as self-induced vomiting or the misuse of laxatives and diuretics, but is defined by the **absence of objective binge eating episodes**. Individuals with this disorder engage in purging behaviors after consuming a normal amount of food or a small snack because of an intense preoccupation with body shape and weight. Because the core diagnostic criterion for Purging disorder specifically **excludes** the "episodes of binge eating" mentioned in the question, it cannot be the correct answer.
