Anorexia Nervosa is an eating disorder which consists of a person severely limiting the amount of food he or she consumes. A person suffering from Anorexia usually sees themselves in a distorted fashion and has an intense fear of gaining weight. Their manipulation of food intake and weight loss is a method for dealing with emotional issues. Anorexia is considered a disease and must be treated professionally. If a person continues without treatment, the long term effects could be fatal.

Anorexia can be caused by a number of different issues. Causes of Anorexia include psychological issues (certain personality traits such as perfectionism) or a career or hobby that requires the person to look a certain way (model, ballet dancer, etc.). Anorexia is commonly found in athletes who are required to maintain a certain appearance or weight (wrestling).
Some conditions that occur due to Anorexia are malnutrition, heart problems, hair loss, osteoporosis, depression, fatigue or anxiety. Of the 1% of the population that suffers from Anorexia, 90% are women. Anorexia usually develops during childhood but there are cases which begin in adulthood.
