Many people have mild forms of anorexia nervosa and are open to treatment. These people will respond well, particularly when a variety of approaches are combined. For people who have lost a great deal of weight and have medical complications, aggressive care can reverse a downward course. There is a significant risk of death for people who have been hospitalized for medical complications of anorexia nervosa, especially when they are very resistant to treatment. However, the majority of people with anorexia nervosa either improve significantly or have a full recovery. People who have recovered from anorexia nervosa may need long-term support and treatment to prevent relapse.
