What is Anorexia nervosa?
A psychological eating disorder in which a person refuses to eat adequately in spite of hunger and loses enough weight to become emaciated. The illness usually begins with a normal weight-loss diet. The person eats very little and refuses to stop dieting after a reasonable weight loss. The person's body perception is distorted; the person continues to feel fat-even when emaciated.
