In this procedure, Dr. Brakta robotically removes 80 percent of the stomach. The remaining 20 percent is a small pouch about the size and shape of a banana.
The smaller stomach that remains holds less volume of food than a normal stomach, which limits the amount of food and calories you can consume. Hormones associated with the stomach are also affected so you feel less hungry and more satisfied when you eat. Blood sugar levels may be easier to control and research shows this procedure could help improve type 2 diabetes.
