Each year, more than 5 million Americans are affected by serious and often life-threatening eating disorders such as anorexia nervosa, binge-eating, bulimia nervosa, compulsive eating, obesity, and pica. Left untreated, the emotional, psychological and physical consequences can be devastating, even fatal. Eating disorders know no class, cultural, or gender boundaries and can affect men, women, adolescents, and even children, from all walks of life. Eating disorders can be treated and a healthy weight restored. However, the longer abnormal eating behaviors persist, the more difficult it can be to overcome the disorder and its effects on the body. Many treatment plans are comprehensive due to the complex interaction of emotional and psychological problems in eating disorders.
