Bariatric surgery, also known as weight loss surgery, refers to the operations designed to reduce weight (bariatric come from the Greek meaning pressure or weight). Operations may restrict the amount you are able to eat (restrictive operations such as the gastric band sleeve gastrectomy) or both restrict the amount you can eat and reduce the amount you can absorb (gastric bypass, mini gastric bypass or duodenal switch). The term does not include procedures for surgical removal of body fat such as liposuction or abdominoplasty (tummy tuck).
