Anorexia

Eating Disorders: Anorexia Nervosa & Bulimia Nervosa

People with anorexia nervosa obsess about their weight and the food they eat and attempt to maintain their weight far below normal.  They may starve themselves to prevent weight gain or to continue losing weight. People with bulimia nervosa eat large amounts of food all at one time and then try to get rid of the extra calories by vomiting or excessive exercise. The disorders make the person preoccupied with weight and body shape, to judge themselves severely and harshly for  self-perceived flaws. With treatment, people with anorexia and/or  bulimia nervosa return to healthier eating habits and reverse some of the serious complications of the disorder.
