Anorexia Nervosa is a potentially life-threatening social and psychological eating disorder characterized by self-starvation and excessive weight loss. The majority of suffers are female, but there are also cases of Anorexia Nervosa in men
Weight loss is achieved by a variety of obsessive behaviors. Most individuals with this disorder strongly deny it. A feeling of control is gained by severely restricting the amount of food eaten. The ability to do without food is viewed as success in attempting to cope with life's stresses. Because early detection is important to successful recovery, it is important to recognize the common warning signs and symptoms of anorexia.

Anorexia nervosa involves self-starvation. The body is denied the essential nutrients it needs to function normally, so it is forced to slow down all of its processes to conserve energy. This "slowing down" can have serious medical consequences.
- An abnormally slow heart rate and low blood pressure, which mean that the heart muscle is changing.
- Reduction of bone density (osteoporosis), which results in dry, brittle bones.
- Muscle loss and weakness.
- Severe dehydration, which can result in kidney failure.
- Fainting, fatigue and overall weakness.
- Dry hair and skin; hair loss.
- Growth of a downy layer of hair called lanugo all over the body, including the face.
- It typically develops in early to mid-adolescence.
- It affects about 1 in 2400 adolescents.
- 90-95 percent of individuals with anorexia nervosa are female.
- It is usually preceded by dieting behavior.
- Psychological problems are displaced onto food.
- A need to enjoy food vicariously by cooking it, serving it or being around it is common.
- Body image disturbance (misperception of body size and shape) is common.
- Between one-third and one-half of anorexics subsequently begin purging.
- Approximately 90-95% of anorexia sufferers are girls and women (Gidwani, 1997).
- Between 1-2% of American women suffer from anorexia (Zerbe, 1995).
- Anorexia is one of the most common psychiatric diagnoses in young women (Hsu, 1996).
- Between 5-20% of individuals struggling with anorexia will die. The probabilities of death increases within that range depending on the length of the condition (Zerbe, 1995).
