Bariatric surgery refers to surgical procedures which alter the functioning of the gastrointestinal tract with the purpose of facilitating weight loss. Obesity is defined as body mass index (BMI) of 30 or greater; a BMI of 40 or greater is considered “severely” or “morbidly” obese. Morbidly obese individuals are potential candidates for surgery to achieve substantial weight loss. Those with BMI between 35 and 40 may also be candidates for surgery if their condition is complicated by severe comorbidities such as obstructive sleep apnea (OSA), obesityhypoventilation, or difficult-to-control diabetes. Bariatric surgery has a low complication rate (operative mortality is less than 1.5%), but patients should demonstrate understanding of lifestyle and dietary changes necessary after surgery. The screening process should be rigorous and include behavioral, psychosocial, and medical evaluations.
