Is Bariatric or weight loss surgery effective in losing weight?

Bariatric surgery for weight loss

Bariatric surgery, often referred to as weight loss surgery, is known to include a number of procedures which are performed on people suffering from obesity. This type of weight loss is achieved by the aid of a gastric band which is tied around the stomach in order to constrict it or reduce its size.  It can also be done by removing a portion of the stomach and this procedure can again be performed in two ways- sleeve gastrectomy or biliopancreatic diversion with duodenal switch. Another way to perform bariatric surgery is by resecting and re-routing the small intestine to a small stomach pouch. This is called gastric bypass surgery. Bariatric surgery is considered as a type of last resort option. Doctors recommend it only if all other methods of losing weight for better health have failed. The right type of surgery to suit you depends on a number of different factors. These factors ought to be discussed with your doctor well in advance and in detail before you opt for the surgery. In open bariatric surgery, a single large cut is made in the abdomen by your surgeon. More often than not, laparoscopic surgery is performed in which several small cuts are made and thin surgical tools are inserted into the body through the cuts. A small scope attached with a camera is also inserted which helps to project internal images on a video monitor. The latter is much less riskier and less painful than the former. Plus, chances of scarring are also quite less in laparoscopic surgery. It also provides for a faster recovery. If you’re someone who has had a stomach surgery before, suffering from a high degree of obesity or are facing some other serious medical risks, your surgeon might suggest you an open surgery. The following is a comparative study of the different types of bariatric surgeries.
