Weight Loss Surgery
Roux-en-Y Gastric Bypass
This procedure involves creating a small stomach pouch, so less food can be consumed. The intenstine is connected to the pouch and rerouted. Food bypasses the lower stomach, the first segment of the small intestine (duodenum) and part os the second segment (jejunum). A direct connection is created from the stomach to the lower segment of the small intestine, by passing small and early portion of the digestive tract that absorb calories and nutrients. |

The benefits of gastric bypass surgery
Gastric bypass surgery tends to produce greater weight loss than other surgeries.
Weight loss surgery patients lose about two-thirds of their excess weight within one year.
While some weight rebound may occur, most patiebnts can keep off roughly 50 kgs of the weight they’ve lost over the long term.
Also many of the serious complications of obesity may resolve or improve after weight loss including diabetes, high blood pressure, sleep apnea, joint plain, and incontinence.
Gastric Sleeve
The gastric sleeve is a surgery only on the stomach and does not involve any surgery on intestine. The smaller stomach pouch restricts food intake by allowing only a small amount of food to be eaten at one time. Gastric Sleeve is now an established first procedure (first stage of a two part surgery) to prepare the obese patient for gastric bypass. There is no reroutine of the intestine. There is no new connections made between stomach and small intestine in this procedure. There is no malabsorption. There is no dumping syndrome. Also there is no need for nutritional supplements. The potential complications of the operation on average are typically less than 0.5 %. |

The benefits of gastric sleeve
No changes made in the intestinal anatomy
Less complicated surgery compared to Gastric Bypass surgery
GS does not require the implantation of a foreign body such as a silastic ring used in gastric banding.
The procedures not only mechanically decreases the size of the stomach but also decreases the secretion of the hunger hormone ghrelin which is responsible for the feeling of satiety (fullness).
The procedure offers the benefits of initially decreasing the body weight in the severely obese patient to prepare this patient for a staged procedure or other surgery at a later time.
