Could radical weight-loss surgery help prevent type 2 diabetes?

Could bariatric surgery — often thought of as a drastic, last-resort measure for weight loss — be one way to reduce the risk of developing type 2 diabetes?

New research published in Monday’s Lancet Diabetes & Endocrinology suggests that such surgery could cut the risk by 80 percent in those who are obese.

Using electronic health records from the United Kingdom, researchers identified 2,167 obese adults who had gastric bypass or other type of weight-loss surgery and compared them against 2,167 obese patients who did not have such treatments. Martin Gulliford, a professor of public health at King’s College in London, and his colleagues reported that the incidence of diabetes among those who had the surgery was 80 percent less, even after controlling for other risk factors such as smoking and high blood pressure. Up to 3 percent of those who are very obese develop diabetes each year.
