Which eating disorder is characterized by purging, use of laxatives, and mood swings?

Bulimia nervosa is characterized by a cycle of binge eating followed by purging behaviors, which can include vomiting, the misuse of laxatives, fasting, or excessive exercise. Individuals with bulimia often experience significant mood swings related to their eating patterns, feelings of guilt, and a distorted body image. The act of purging is a key component of bulimia, as it is a method individuals use to try to control their weight after episodes of overeating.

In contrast, anorexia nervosa primarily involves drastic weight loss and self-starvation rather than cycles of bingeing and purging. Binge-eating disorder focuses on episodes of uncontrolled eating without subsequent purging behaviors. Orthorexia refers to an unhealthy obsession with eating healthy or clean foods but does not involve bingeing or purging behaviors. Understanding these distinctions clarifies why bulimia nervosa is the eating disorder associated with purging and mood swings.
