Sleeve gastrectomy is a surgical procedure that induces weight loss by restricting food intake. With this procedure, which is usually performed laparoscopically, the surgeon removes approximately 75 percent of the stomach. This results in the stomach taking on the shape of a tube or “sleeve” which holds much less food. Although originally devised as the first stage of a two stage procedure for super obese or high-risk patients, the sleeve gastrectomy is now commonly and successfully used as a destination procedure for weight loss in persons with BMI greater than 40. Patients can expect to lose 50% or more of their excess weight in three years. 

The procedure does not require implantation of a band, nor does it re-route the digestive process. Hormonal changes after the procedure help patients to feel sated, eat less, as well as improve or resolve diabetes.

 

About Surgery. The surgery is performed under general anaesthesia, and it takes 1—1.5 hours. Mostly are performed laparoscopically, which involves inserting instruments through makes 4 to 6 small incisions in the abdomen. The surgeon views the operation on a video screen.

Your surgeon uses staples to divide your stomach into a small section to form the “sleeve” or tube and a larger section 70-80 percents of it witch are removed.You eat less food and as a result, your body will absorb fewer calories.

​

Post Surgery. In the same way as a gastric bypass, a sleeve gastrectomy produces weight loss as a result of restriction and through an impact on appetite regulating hormones. Unlike a gastric bypass however, a sleeve gastrectomy does not involve bypass of the bowel,

so there is a much lower risk of vitamin and mineral deficiency.On average a sleeve gastrectomy patient will lose 50-70% of their excess weight in the first 2 years with most weight loss in the first year.
