Your surgeon will remove about 80% percent of the stomach (this is the gastrectomy), leaving the remaining portion of the stomach shaped like a tube, or sleeve. Just below the opening of the stomach (this is called the pylorus) is the duodenum. This is the first part of the small intestine. Your surgeon will divide the small intestine and shape it into a loop that is connected to the stomach. This is the only intestinal connection in this procedure.
How Does SADI Surgery Work?
- The smaller, newly created stomach holds less food, which means fewer calories are ingested.
- More of the small intestine is bypassed which results in the digestion of less food.
- The altered food pathway changes the levels of gastrointestinal hormones that decrease hunger, increase fullness, enable the body to lose weight, and allow you to reach and maintain a healthy weight. This often results in the improvement of obesity-related conditions including diabetes.
