The Eating Disorders Service provides assessment and treatment for adults afflicted with Anorexia Nervosa and/or Bulimia Nervosa. Anorexia is an eating disorder in which there is a severe and prolonged inability to eat, with marked weight loss. Bulimia is an eating disorder in which a person regularly binge eats, then tries to prevent weight gain by self-induced vomiting, water pills, laxatives, fasting or extreme exercising. Both disorders can be treated using individual, group and/or family psychotherapy, and nutrition counseling. Depending on the degree of weight loss and the state of physical health when the person enters treatment, there will be greater or lesser control of the person's eating and of the total environment.
