What is a gastric sleeve?
Gastric sleeve surgery, also known as sleeve gastrectomy, is a permanent weight loss procedure. About 85% of the stomach’s volume is removed and the remaining bit is typically shaped like a ‘tube’ or ‘sleeve’. The aim of this procedure is to reduce the volume of food that the stomach can hold.
Once you have had gastric sleeve surgery, you won’t be able to consume large amounts of food in one sitting. Your ‘new’ stomach only holds 200 ml of volume compared to a ‘normal’ stomach, which can typically hold about 1500ml.
Generally, it is expected that a person could lose about 70% of their excess weight within a year to 18 months after the surgery.
