Bariatric surgery is a minimally invasive technique (laparoscopic surgery) that causes weight loss by limiting the amount of food the stomach can hold. Bariatric Surgery in India, the most common bariatric surgery procedures are gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch. Immediately after bariatric surgery, the patient is restricted to a liquid diet, which includes foods such as fruit juices or sugar-free drinks and desserts until the patient recovers from the surgery.
Laparoscopic Adjustable Gastric Band
In this type of surgery, the surgeon places an inner inflatable band at the top of the stomach that creates a small pouch. By this method, eating even a small quantity of food will make the stomach full and reduces hunger by promoting the feeling of fullness, thus inducing weight loss. Reducing the size of the pouch is done gradually over time.
In gastric sleeve surgery, also called vertical sleeve gastrectomy, a surgeon removes a part of stomach such that it looks like a banana-shaped section that is closed with staples. Like gastric band surgery, this surgery reduces the amount of food (and thus calories) that can be consumed, making you feel full sooner. The greater impact also is on the gut hormones and gut bacteria that may affect appetite and metabolism. This type of surgery cannot be reversed because some of the stomach is permanently removed. Recent evidence suggests that the gastric sleeve procedure and the gastric bypass procedure are effective in improving type 2 diabetes and weight loss.
Gastric bypass surgery, also called Roux-en-Y gastric bypass, has two parts. First, the surgeon staples the stomach and creates a small pouch in the upper section. The staples make the stomach very small, so the patient eats less and feels full sooner. Next, the surgeon cuts the small intestine and connects the lower part of the small intestine directly to the small stomach pouch. Once this is done, food bypasses most of the stomach and also the upper part of the small intestine. Since there is less digestion of food by the smaller stomach pouch, and small intestine the body absorbs fewer calories. The surgeon then connects the bypassed portion beyond down to the lower part of the small intestine. The reroute of the food stream produces changes in gut hormones suppresses hunger and reverse obesity induces type 2 diabetes. Gastric bypass is difficult to reverse, although a surgeon may do it if medically necessary.
This surgery, also called biliopancreatic diversion with duodenal switch, is a bit complex than the other surgeries. The duodenal switch involves two separate surgeries. The first is similar to gastric sleeve surgery. In the second surgery, bypassed small intestine is redirects food to bypass most of your small intestine. The surgeon also reattaches the bypassed section to the last part of the small intestine reconnected to the last portion of the small intestine so that digestive juices mix with food. When the patient eats, the food goes through a newly created tubular stomach pouch empties directly into the last part of the small intestine.
