How are eating disorders diagnosed?

Health professionals or mental health professionals can diagnose an eating disorder based on medical history, symptoms, thought patterns, eating behaviors, and a physical examination.

Eating disorders are best treated when managed by a team of professionals, often including a doctor, a dietitian or nutritionist, and a therapist. Treatment includes nutrition counseling, medical care, and psychotherapy (individual, group, and family). Your doctor may prescribe medications to treat binge eating disorder, anxiety, depression, or other mental health problems.
