Anorexia nervosa is an eating disorder which is characterized by excessive concern about one’s weight. It is also classified as an emotional disorder. A person who has anorexia nervosa will be obssessed about his or her weight and usually has the misconceived perception that he or she is overweight. Anorexia commonly occurs in teenage girls and young women, although males and women in other age groups may also suffer from the disorder.
The most common sign of anorexia nervosa is weight loss for no apparent reason. Of course, if the person has another medical condition, the weight loss may be due to that; but barring any other conditions, drastic weight loss in a person may be a sign that he or she has anorexia nervosa. Eating habits definitely support this weight loss, so they should be examined. If a person has developed the habit of eating very small portions or flat out refusing to eat, then the chances are that he or she has the eating disorder.
More so, due to the lack of nutrition, people with anorexia nervosa will have dull brittle hair, skin, and nails. Hair loss may also be an effect of the eating disorder.
Changes in behavior are often observed in people with anorexia nervosa. If a person suddenly becomes obsessed with food, such that he or she keeps counting calories but never really eats much, then it could be a sign of anorexia nervosa. Being overly critical about one’s physical appearance can also be a sign of the disorder.
