This Review provides an overview of the symptoms, complications, nutritional deficiencies and medical disorders associated with Roux-en-Y gastric bypass—the most frequently performed bariatric procedure in the USA and Canada. Although some symptoms are expected and predictable, some complications may require active medical or surgical intervention. Physicians should be able to predict and manage most postoperative medical and nutritional disorders and should be prepared to assess patients for potential referral for surgical intervention or revision.
