Metabolic Surgery for Type 2 Diabetes

Back to the nypdigestive.org Home Page

NewYork-Presbyterian is currently offering metabolic surgery to severely obese patients with Type 2 diabetes. We are also conducting clinical trials to treat Type 2 diabetes in patients with moderate to mild obesity, or no obesity at all.

Our new program is based on work with morbidly obese patients, where we discovered that 90% of morbidly obese patients who underwent gastric bypass surgery experienced a reversal of diabetes – often within days to weeks of the surgery, and apparently independent of weight loss.

Types of Metabolic Surgery

While severely obese patients receive traditional procedures such as the Roux-en-Y gastric bypass or the gastric banding, those who are not as obese or not obese at all may undergo either the standard gastric bypass or a modified gastrointestinal bypass, in which the stomach is completely or partially spared and the duodenum and jejeunum – sections of the upper small intestine – are bypassed. This seems to reverse abnormalities in blood glucose regulation.

Recent research indicates that this bypassed area of the upper small intestine could be the site that helps regulate body weight and appetite control as well as control of blood glucose through hormone action.
