This surgery is another way of reducing the stomach’s sizes and making the patient eat less. Sleeve gastrectomy is not reversible like the gastric band and it’s done laparoscopically. And it’s actually removing a large part of the stomach by creating a small incision. It totally changes the shape of the stomach and also decreases the number of hunger hormone that is called ghrelin. And it is done for a patient with BMI over 40 or someone with BMI in 35-40 range and related complication like high blood pressure, heart disease, fatty liver, sleep apnea or type 2 diabetes. You should take a calcium supplement and multivitamin daily and vitamin B injection monthly otherwise you get nutrient deficiencies. It was the helper for up to 85 percent of the patient and they have lost up to 60 percent of their excess weight in two years. It has less risk than gastric bypass and after the surgery, the stomach has natural normal function but in a smaller size. It can improve lots of related disorder and your life expectancy. About 0.5 percent of patients experience related complications like losing hair, some kind of nervous condition, unexpected pain or infection.
