Eating disorders: Facts and warning signs

Eating disorders are common. They can lead to serious physical and emotional health risks. They have the highest rates of death of any psychiatric illness. Cardiac arrest and suicide are among the leading causes of mortality among those with such disorders.

Anorexia nervosa affects about eight million people in the United States, seven million of whom are young women. Anorexia affects approximately one percent of adolescents. Bulimia affects two to five percent.

Eating disorders are more common in girls than boys. However, there has been a noted increase in the number of adolescent males being treated for eating disorders. Among adolescent and young adult females, eating disorders are one of the most common chronic illnesses.

While eating disorders may lead to dramatic weight loss, they may also be accompanied by weight gain or no change in weight at all. Eating disorders represent a spectrum of emotional illnesses, characterized by the patient’s struggle with self-acceptance and body dissatisfaction.
