What causes binge eating disorder?

Like other eating disorders, binge eating disorder results from a mix of factors related to your genes, your thoughts and feelings—particularly about your weight and shape—as well as cultural and social issues and your environment. Binge eating disorder also has been linked to depression and anxiety.

For some people, dieting in unhealthy ways—such as skipping meals, not eating enough food, or avoiding certain kinds of food—may contribute to binge eating.
