It is a chronic illness identified in children, adolescents, and adults worldwide and in the U.S. alone, 35 percent of adults (roughly 100 million people) and 17 per cent of children are obese.It is therefore not surprising that today bariatric surgery has become an important player in tackling the heat burden of obesity. Bariatric surgeries are one of the most rapidly growing operative procedures performed worldwide, with an estimated >340,000 operations performed in 2011, and in Asia alone the absolute growth rate was 449 per cent between 2005 and 2009.Over the past five years the number of weight-loss operations performed in the U.S. has been relatively stable with an estimated 179,000 bariatric surgeries performed in 2013. Of those, 34 per cent were gastric bypass, 42 per cent were sleeve gastrostomy, 14 per cent were gastric band, and 1 per cent was biliopancreatic diversion with duodenal switch. The remaining six per cent were revisional procedures.Complications following surgical treatment of severe obesity vary based upon the procedure performed and can be as high as 40 per cent. Below the major complications of bariatric surgery are outlined based on the different procedures individually.
