Sleeve gastrectomy is a type of bariatric surgery that limits the amount of food you can eat. Clinical studies have shown that sleeve gastrectomy patients lose an average of 55-75% of their excess weight. The procedure has also been shown to resolve high blood pressure and obstructive sleep apnea, and to help improve diabetes and high cholesterol.
During this procedure, your surgeon removes approximately 85% of the stomach, leaving a small pouch shaped like a sleeve. It is larger than the stomach pouch created during gastric bypass and is about the size of a banana. The sleeve typically holds between 50 to 150 mL of food. Because your stomach is smaller, it limits the amount of food you can eat at one meal.
Unlike gastric bypass, sleeve gastrectomy does not involve any intestinal re-routing, which reduces the risk of long-term nutritional deficiencies. Food passes through the digestive tract in the normal order, allowing your body to fully absorb vitamins and nutrients. No post-operative adjustments are required.
