Anorexia (an-o-REK-see-uh) Nervosa — often simply called anorexia — is a disorder characterized by abnormally low weight, an intense fear of gaining weight and a distorted perception of weight. People with anorexia place a high value on controlling their weight and shape, using extreme efforts that tend to significantly interfere with their lives. To prevent weight gain or to continue losing weight, people with anorexia usually severely restrict the quantity of food they eat. They may control calorie intake by vomiting after eating or by misusing laxatives, diet aids, diuretics, or enemas. They may also try to lose weight by exercising excessively. No matter what proportion weight is lost, the person continues to fear weight gain. Anorexia isn't really about food. It's an extremely unhealthy and sometimes life-threatening way to try to cope with emotional problems. When you have anorexia, you regularly equate thinness with self-worth. Anorexia, like other eating disorders, can take over your life and may be very difficult to beat. But with treatment, you'll gain a far better sense of who you're, return to healthier eating habits and reverse a number of anorexia's serious complications.
