This reduced risk was independent of other factors such as smoking, high blood pressure and high cholesterol, according to the study, Health Day said.
"Our results suggest that bariatric surgery may be a highly effective method of preventing the onset of new diabetes in men and women with severe obesity," study author Martin Gulliford, a professor of public health at King's College London, said in a journal news release.
"We need to understand how weight-loss surgery can be used, together with interventions to increase physical activity and promote healthy eating, as part of an overall diabetes prevention strategy," he added.
Being overweight or obese is a major risk factor for diabetes, and up to 3 percent of severely obese people develop diabetes each year, the study authors noted in the news release.
This study included more than 2,100 obese adults without diabetes who underwent weight-loss surgery, such as gastric bypass or gastric banding, and the same number of obese adults who did not have weight-loss surgery or other obesity treatments.
