Definition

Anorexia nervosa is an eating disorder that involves limiting the amount of food a person eats. It results in starvation and an inability to stay at the minimum body weight considered healthy for the person's age and height.

Persons with this disorder may have an intense fear of weight gain, even when they are underweight. Not eating enough food or exercising too much results in severe weight loss.
