ABSTRACT
As a field of surgery, bariatric procedures have never been safer or more effective for achieving meaningful and sustainable weight loss. However, all of the currently performed operations result in dramatic changes in gastrointestinal anatomy, physiology, and/or dietary habits. Unfortunately, a good surgical result does not ensure a successful outcome. Even after excellent weight loss, patients must still be carefully followed long term to guard against the development of nutritional or gastrointestinal complications (Table 1).
