Gastric bypass, also referred to as Roux-en-Y, is a surgical procedure to cut across the top of your stomach and sealing it off from the rest of the stomach. The size of this pouch is as much as a walnut, so it can’t hold much food and drink. Therefore, the absorption of nutrients decrease. This surgery is not reversible. This procedure is performed under general anesthesia.

Gastric Bypass Surgery Procedure in Iran


There are two components to the procedure. First, a small stomach pouch, approximately one ounce or 30 milliliters in volume, is created by dividing the top of the stomach from the rest of the stomach. Next, the first portion of the small intestine is divided, and the bottom end of the divided small intestine is brought up and connected to the newly created small stomach pouch. The procedure is completed by connecting the top portion of the divided small intestine to the small intestine further down so that the stomach acids and digestive enzymes from the bypassed stomach and first portion of the small intestine will eventually mix with the food.

Gastric bypass (Roux-en-Y)


The gastric bypass works by several mechanisms. First, similar to most bariatric procedures, the newly created stomach pouch is considerably smaller and facilitates significantly smaller meals, which translates into fewer calories consumed. Additionally, because there is less digestion of food by the smaller stomach pouch, and there is a segment of the small intestine that would normally absorb calories as well as nutrients that no longer has food going through it, there is probably to some degree less absorption of calories and nutrients.

Most importantly, the rerouting of the food stream produces changes in gut hormones that promote satiety, suppress hunger, and reverse one of the primary mechanisms by which obesity induces type 2 diabetes.
