Pennington Biomedical Study Shows Bariatric Surgery More Effective than Lifestyle for Type 2 Diabetes Remission

New research from Pennington Biomedical shows that bariatric surgery is more effective and has longer-lasting results than lifestyle changes and medications in achieving remission of type 2 diabetes. 

More than 34.2 million Americans, or 10.5 percent of the population, have type 2 diabetes, according to the Centers for Disease Control and Prevention. Obesity is a significant contributory factor in the development of diabetes. Approximately 90 percent of people with type 2 diabetes are overweight or have obesity. These intertwined chronic health issues have an enormous health burden on both individual and societal levels.

The study, published in the journal Diabetes Care, assessed 316 patients with type 2 diabetes to determine the effectiveness and long-term results of metabolic surgery.

“Treatment guidelines from the American Medical Association, American Diabetes Association, and many other leading medical organizations, are that metabolic surgery is an effective treatment for type 2 diabetes,” said Pennington Biomedical Executive Director John Kirwan, PhD, who led the study. “Despite growing consensus, many health insurers do not provide coverage for metabolic surgery because we haven’t had a sufficiently large, randomized controlled trial that considered how long the results of surgery last relative to medications and lifestyle changes.”

“Even when patients are provided with education in nutrition, exercise, self-monitoring and the newest diabetes medications on the market, only 2.6 percent of patients were able to achieve diabetes remission during the study,” Kirwan noted. “When we looked at patients who underwent metabolic surgery, even three years later, 37.5 percent had achieved lasting remission of their diabetes,” he added.

The study notes that less than one percent of individuals eligible for bariatric surgery receive the treatment, likely due to both patients’ and their providers’ concerns about long-term safety and lasting results.

The study also found that metabolic surgery was superior to medication and lifestyle changes in lowering HbA1c, fasting glucose, body weight, and other cardiovascular risk factors with substantially less medications.

“It is our hope that physicians will have greater confidence in recommending bariatric surgery to their patients, and that health insurers will see the health benefits and ultimately, cost-savings that can be achieved by covering metabolic surgery,” Kirwan said.
