Treatments vary from patient to patient, and usually depend on the severity of the illness. For example, a person who has had Anorexia for 15 years, and is at a dangerously low weight, may need to be committed to a hospital, and treated with aggressive mental therapy. While treatment for a person with Anorexia for less than a year, who is still eating some food, may involve seeing a therapist and dietician on a weekly basis.
