A case of comorbid anorexia nervosa, bulimia nervosa, and Munchausen's syndrome.

Reports of comorbid eating disorders and Munchausen's syndrome are rare. As part of a follow-up study of the outcome of anorexia nervosa, medical records and direct structured psychiatric interview data were collected on all women treated for anorexia nervosa in Christchurch, New Zealand between 1981-1984. On interview, one participant received diagnoses of anorexia nervosa, bulimia nervosa, and factitious disorder (Munchausen's syndrome). The subject interwove symptoms of her eating disorders with factitious presentations on several occasions. This diagnosis had not been apparent prior to compilation of all medical records.
