Bulimia Nervosa (BN) is an eating disorder characterized by recurrent episodes of binge eating followed by compensatory behaviors—such as self-induced vomiting, fasting, excessive exercise, or misuse of laxatives or diuretics—to prevent weight gain. These behaviors typically occur at least once a week for three months and are accompanied by an intense preoccupation with body shape and weight. Unlike anorexia nervosa, individuals with bulimia usually maintain a body weight within or above the normal range, which can make the disorder less visible but equally dangerous. Treatment emphasizes interrupting the binge–purge cycle, normalizing eating patterns, addressing cognitive distortions about weight and control, and improving emotion regulation and self-worth.
