This case study illustrates the process and challenges of multidisciplinary treatment of an adolescent with anorexia nervosa. A biopsychosocial model of anorexia nervosa is presented. This case study demonstrates the need for a multidisciplinary approach in which a physician, psychotherapist, and dietician with training in the treatment of eating disorders collaborated in an outpatient setting. This case was complicated by comorbid obsessive-compulsive personality features and limited adherence with treatment recommendations. A 1-month hospitalization on an inpatient unit is described to illustrate the importance of maintaining communication among all health care providers during the transition into and out of the hospital. This case demonstrates the importance of avoiding the pitfalls of splitting or scapegoating among the treatment team.
