Bulimia nervosa is a serious eating disorder. It is normally called just bulimia. People with bulimia have cycles of binge eating followed by compensatory behaviors to stop them gaining weight. These behaviors may include self-induced vomiting, the misuse of laxatives or diuretics, fasting, or excessive exercise.[1] Bulimia typically starts during adolescence or early adulthood and can have significant physical, emotional, and social consequences if left untreated.[2]
