    Weight Loss Surgery Treats Diabetes

    Study Shows Gastric Banding Surgery More Effective Than Lifestyle-Modification Programs

    Jan. 22, 2008 -- Weight loss surgery proved to be a highly effective treatment for type 2 diabetes in a newly published study, with almost three out of four surgically treated patients showing no evidence of the disease two years later.

    Patients who had gastric banding surgery lost an average of 20% of their body weight within two years. That compares with less than 2% during the same time period in patients who had conventional therapy that focused on intensive lifestyle-modification programs involving diet and physical activity. Many of the patients were on diabetes medications.

    The study included just 60 patients who had recently been diagnosed with type 2 diabetes. But if larger investigations confirm the findings, weight loss surgery may prove to be a cure for many people with diabetes, researcher John B. Dixon, MBBS, PhD, of Melbourne, Australia's Monash University, tells WebMD.

    The findings appear in tomorrow's issue of The Journal of the American Medical Association.

    "I really do think that within a few years surgery will become a common procedure for type 2 diabetes," Dixon says.

    Weight Loss Surgery and Diabetes

    Gastric banding surgery reduces the size of the stomach to help patients eat less.

    Both gastric banding surgery and gastric bypass surgery have been shown to be effective for weight loss, but their impact on obesity-related diseases like diabetes has only recently begun to be studied.

    In the newly reported research, patients were randomly assigned to receive either laparoscopic adjustable gastric banding (also referred to as lap banding) or conventional diabetes treatment with a focus on lifestyle modifications though diet and exercise.

    The patients had been diagnosed with diabetes no more than two years before entering the study.

    Fifty-five patients completed the study, and 26 (43%) achieved diabetes remission at two years.

    At the completion of the study, 22 of 30 (73%) surgically treated patients showed no evidence of type 2 diabetes, compared with four of 30 (13%) patients in the lifestyle-intervention group.

    Surgically treated patients lost an average of 62% of their excess weight, compared with an average loss of 4.3% in patients who did not have the surgery.

    No serious complications occurred in either treatment group. Two of the surgical patients required nonurgent surgical replacement of their bands.
