Types of Bariatric Surgery
Roux-en-Y Gastric Bypass
Roux-en-Y Gastric Bypass surgery is one of the common methods of performing gastric bypass. Basically, it reduces your diet by cutting down your capacity to eat much at once and reduces the absorption of nutrients in your body. Your doctor will cut at the top of your stomach and seal it off from the remaining stomach. This ends in a small pouch that cannot hold anything more than an ounce of food. Your doctor will cut off the small intestine and sew it to this pouch. When you eat food, it enters this pouch and then directly the small intestine.
During sleeve gastrectomy, your surgeon will remove more than 75 percent of your stomach to leave a long pouch behind. A small stomach doesn’t have the capacity to hold food. Ultimately, it produces less ghrelin (appetite-regulating hormone) that brings down your desire to eat more food. There is no need for re-routing of intestines and you can see noticeable weight loss.
Biliopancreatic diversion with duodenal switch
Biliopancreatic diversion with duodenal switch is a two-part surgery. First, your surgeon will perform a sleeve gastrectomy like procedure. Next, he or she will connect the end portion of the intestine with the duodenum near to your stomach. This is a duodenal switch and biliopancreatic division. It bypasses a majority of your intestine. It not only limits the amount of food that you can eat but also reduces the absorption of the nutrients.
