What characterizes bulimia nervosa?

Bulimia nervosa is primarily characterized by episodes of binge eating followed by compensatory behaviors, such as purging. Individuals with this disorder typically consume large quantities of food in a short period, often feeling a loss of control during these episodes. In an attempt to prevent weight gain from binge eating, they may engage in behaviors like self-induced vomiting, excessive exercise, or the misuse of laxatives.

This cycle of eating and purging is a central feature of bulimia nervosa, distinguishing it from other eating disorders such as anorexia nervosa, which involves a refusal to eat and severe weight loss. The focus on binge eating and the subsequent efforts to counteract the effects of those binges through purging is what defines bulimia nervosa and underscores the psychological aspects involved in the disorder.

Understanding this characteristic helps identify the disorder and differentiate it from other eating-related issues, effectively guiding treatment and support strategies.
