Gastric bypass surgery is a common and successful obesity procedure, in which both the amount of food you can consume is limited, and the amount of calories you absorb is reduced. The main difference between gastric bypass surgery and a sleeve gastrectomy is the shortening of the food pathway. The main difference between the Roux-en-Y bypass and the simplified mini gastric bypass is that in the Roux-en-Y, the intestines are reconnected (anastomosed) in two places and not one.
Some of the advantages of a gastric bypass are that it produces significant long-term weight loss, and leads to favorable changes in gut hormones that reduce appetite and improve satiety (feeling full). Our surgeon will be able to advise you whether you are a good candidate for gastric bypass surgery in Dubai.
There are two main steps in the gastric bypass surgery and these are done through small incisions in your abdomen using special keyhole (laparoscopic) surgical instruments. First, the surgeon will create a small stomach pouch, approximately 30 milliliters in volume, by separating the top of your stomach from the rest of it. Next, he will divide the first portion of your small intestine, and then bring the bottom part of it up to connect it to your newly formed stomach pouch. He will finish by connecting the top portion of the divided small intestine to the small intestine further down so that digestive enzymes and stomach acid from the bypassed stomach and first portion of small intestine can mix with the food.
The effect of this operation is threefold. First, the new smaller stomach pouch requires substantially smaller meals. As a result, you will feel full after eating just a small amount of food, and thus you will consume fewer calories.
Second, you will absorb fewer calories and nutrients because less digestion of food the food takes place due to the smaller stomach pouch and bypassed part of the small bowel.
Third, the fact that the food is rerouted leads to changes in gut hormones that suppress food cravings and promote early satiety.
While complications are rare, they can occur and your doctor will discuss these with you prior to surgery.
