Gastric sleeve surgery, also known as sleeve gastrectomy, is a type of bariatric surgery that involves the removal of about 80% of the stomach, leaving a tubular 'sleeve' about the size and shape of a banana. This procedure is performed laparoscopically and is irreversible. It works by reducing the size of the stomach and thereby limiting the amount of food that can be eaten at one time, while also reducing the production of the hunger hormone ghrelin.
Success Rate: Around 60% to 70% of excess weight loss can be expected within one to two years following the procedure, with high success rates in maintaining significant weight loss over 5 years.
Recovery: Most patients can expect to stay in the hospital for 2 to 3 days following the surgery. Full recovery, including the resumption of normal activities, can usually be expected within 3 to 5 weeks.
