Metabolic surgery is scientifically proven, very safe method for long term remission from type 2 diabetes. Sleeve gastrectomy and diversion procedures alter several hormones and genes controlling insulin production and sensitivity. These alterations result in sufficient insulin production and reduced insulin resistance leading to long term control of blood sugars without the need for tablets or insulin.
These are performed on stomach and intestine by laparoscopic method (by putting small holes on tummy). Metabolic and bariatric surgeries are essentially same. If the purpose of surgery is remission from diabetes and other co-morbid medical conditions, it is called metabolic surgery. If the purpose of surgery is weight loss, then it is called bariatric surgery.
