  • Image not available. The identification and acceptance of eating disorders as a psychiatric illness is increasingly common. They remain difficult to treat as effectiveness trials are limited, and patients are inherently resistant to accepting treatment.
  • Image not available. Eating disorder not otherwise specified is currently the most commonly diagnosed form of eating disorder; however, proposed changes to the diagnostic criteria in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders would separate binge eating disorder as a stand-alone diagnosis.
  • Image not available. Despite strong genetic associations for the development of eating disorders as established in monozygotic and dizygotic twin studies, a clear association with a specific genetic link mutation has not been identified.
  • Image not available. Shifting between eating disorder diagnostic categories is possible, especially when symptom remission is not achieved with treatment.
  • Image not available. Psychiatric comorbidities are common with all forms of eating disorders, and the differential diagnosis should generally include evaluation for depression, schizophrenia, generalized anxiety, and obsessive–compulsive and personality disorders.
  • Image not available. During the process of caloric restoration, calories must be gradually introduced to prevent the potentially fatal complication known as refeeding syndrome.
  • Image not available. Mortality resulting from suicide in eating disorders is not uncommon, and clinicians must monitor closely for suicidality and educate appropriately as they would during the treatment of patients with major depressive disorder with antidepressant therapy.
  • Image not available. The current preferred treatment approach for anorexia nervosa includes a minimum of 6 months of psychotherapy, preferably cognitive behavioral therapy.
  • Image not available. Data supporting the use of medication in anorexia nervosa are largely inconclusive. Primary limitations are small sample sizes and a bias in clinical trials because more highly motivated patients participate in studies.
