Eating Disorders Outcomes
Without treatment—and most patients are not being treated– one-fifth of patients will die prematurely.
Even with treatment, after 8 to 25 years, the premature mortality rates are 4% for AN patients, 3.9% for bulimia nervosa (BN) patients and 5.2% for those with eating disorders not otherwise specified, or EDNOS.
Anorexia nervosa has the highest premature fatality rate of any mental illness (Sullivan, 1995).
