Obesity surgery

OBESITY SURGERY

Obesity surgery, also known as bariatric surgery, are surgical procedures that are performed on people who are obese. This surgery may be considered if you have tried other methods to lose weight, but they failed.

The surgery involves the reduction of the size of the stomach or removal of a portion of the stomach or resecting and re-routing the small intestine to a small stomach pouch. This surgery limits the amount of food you can comfortably eat or decreases the absorption of food and calories or both.

TYPES OF OBESITY SURGERY

  1. Gastric Bypass Surgery: It is also called Roux-en-Y gastric bypass. This type of obesity surgery involves the surgeon creating a small pouch at the top of the stomach. The small intestine is then cut a short distance below the main stomach and connected to the new pouch. With this, the foods and liquids the patient takes flow directly from the pouch into that part of the intestine thereby bypassing most of the parts of the stomach.
  2. Gastric Sleeve: This is also called sleeve gastrectomy. In this surgery, part of the stomach is removed to create a smaller reservoir for food. This is a somewhat less complicated surgery compared to other types of obesity surgeries.
  3. Biliopancreatic Diversion with Duodenal Switch: Here, the surgeon removes a large part of the stomach. He then leaves a valve that releases food to the small intestine and duodenum. After that, he will close off the middle section of the intestine and attaches the last part directly to the duodenum. The separated section is then reattached to allow bile and digestive juices to flow into the intestine.
  4. Laparoscopic Adjustable Gastric Banding: In this method, the surgeon separates the stomach into two pouches with an inflatable band. The surgeon pulls the band tight, like a belt, thereby creating a tiny channel between the two pouches. The band keeps the opening from expanding and is generally designed to stay in place permanently.
