Eating disorders are mental health disorders in which concerns about food, eating, and your weight take over your life. There are many types of eating disorders, including these three:
Anorexia nervosa
Anorexia nervosa is a disorder featuring self-starvation and significant weight loss. This usually includes extremely close tracking of food intake, extremely low-calorie diets, excessive exercise, and other ways of losing as much weight as possible.
People who struggle with anorexia nervosa commonly have a body mass index (BMI) of less than 18.5, but it can vary. Untreated, anorexia nervosa can cause severe physical effects and even threaten your life.
Bulimia nervosa
People who struggle with bulimia nervosa usually keep an extremely strict diet but interspersed are binges in which they eat high-calorie foods. Many people with bulimia purge after their binges, which may involve forced vomiting or use of laxatives, enemas, or diuretics.
Not all bulimics purge, however. Some people with bulimia exercise excessively or use other methods of compensation for their overindulgence during binges. People with bulimia can be underweight, normal weight, or overweight.
Binge eating disorder
Binge eating disorder is similar to bulimia in terms of eating binges. A person who struggles with binge eating disorder, however, doesn’t purge or otherwise try to compensate for their excessive food intake. People with binge eating disorder can range from normal weight to significantly overweight.
Eating disorders often cause low self-esteem, frustration, sadness, and agitation. Many people also have other mental health conditions, including depression and anxiety.
