Weight-Loss Surgery May Prevent Diabetes

Weight-loss surgery can sharply reduce the risk of diabetes in very obese people, a new study finds. The study included more than 3,400 obese people. Just under half of them had so-called bariatric surgery to help weight loss. These procedures reduce the size of the stomach, bypass part of the colon or both. The other people in the study did not have surgery. They just received usual care and advice on weight loss. Nobody had diabetes when the study began. Within 10 years, 110 people in the surgery group developed diabetes. This compares with 392 people in the other group. The diabetes rate was 78% lower for those who had surgery. Two studies released this year showed that weight-loss surgery could reverse diabetes. This study showed that it also could help prevent the disease. But experts quoted by the Associated Press (AP) disagreed on whether surgery should be widely used for that purpose. AP wrote about the study August 23.
