Gastric Sleeve Vs. Gastric Bypass

Gastric sleeve (sleeve gastrectomy) and gastric bypass are the two most common bariatric surgeries performed today. Both are permanent surgeries that help obese persons lose weight if they have been unsuccessful with previous weight loss efforts.

Gastric Sleeve Explained

During gastric sleeve surgery, a portion of the stomach is removed, leaving a sleeve-like section behind connecting the esophagus to the intestine. The sleeve gastrectomy leaves less room for food so you feel full sooner when eating, and removes parts of the stomach that are believed to produce ghrelin, the hormone that makes you feel hungry.

Compared to gastric bypass, gastric sleeve usually results in slower weight loss. This can be beneficial in that slower weight loss may partially alleviate the sagging skin and stretch marks that come with very rapid weight loss.

Gastric Bypass Procedure

With gastric bypass surgery, a significant portion of the stomach is removed, leaving a smaller pouch behind. The small intestine is then rerouted, bypassing most of the stomach and the pylorus, the valve that keeps food from emptying out of your stomach too early. With gastric bypass, there is less room in the stomach so food intake is reduced.   Because of these alterations to the digestive process, fewer calories are absorbed.

Weight loss is typically faster with gastric bypass, allowing the patient reach a healthy weight faster. Some patients who have gastric bypass find that they develop an aversion to some unhealthy foods because their bodies have trouble digesting high carb, greasy, and sugary foods after surgery.

Gastric Surgery Similarities

With both gastric sleeve and gastric bypass, the stomach is altered so that it holds less food, causing the patient to feel full sooner. The procedures differ in technique and each alters the way the body digests food differently.

Neither of these surgeries is a guarantee of weight loss. Both gastric bypass and gastric sleeve can be a catalyst for the lifestyle changes that will help you reach your weight loss goals and live a healthier life.
