What is a key trait of bulimia nervosa?

A key trait of bulimia nervosa is characterized by episodes of overeating, known as binge eating, followed by compensatory behaviors to prevent weight gain. These behaviors often include self-induced vomiting, the misuse of laxatives, fasting, or excessive exercise. This cycle of bingeing and compensating creates a psychological and physical pattern that is central to the disorder.

The disorder signifies not only a focus on weight control but also an underlying struggle with self-esteem and emotional regulation. It's essential to identify this specific pattern of behavior when considering the diagnosis, as it distinguishes bulimia nervosa from other eating disorders, such as anorexia nervosa, which primarily involves intense dietary restriction. Understanding this key trait aids in recognizing the complexities of the disorder and the impact it has on individuals.
