Important Facts
• Athletes are at risk for eating disorders due to the emphasis on low body weight to enhance performance.
• Extreme weight control measures are unhealthy and may put the athlete at risk for chronic disease.
• There are two main categories for eating disorders: anorexia nervosa and bulimia nervosa.
• Food is not the issue with eating disorders, an underlying emotional disturbance is the root cause.
• Professional help is required for recovery from an eating disorder.

General Information
Eating disorders represent an effort to manage emotional problems with abnormal eating behaviors that can have life-threatening physical consequences. A distorted perception of body shape and weight accompanies both of these disorders. See below for defining characteristics:
