Gastric bypass bests banding for weight loss, diabetes, high blood pressure, and cholesterol control

Gastric bypass surgery has better outcomes than gastric banding for long-term weight loss, controlling type 2 diabetes and high blood pressure, and lowering cholesterol levels, according to a new review by UT Southwestern Medical Center surgeons of nearly 30 long-term studies comparing the two types of bariatric procedures. The review, appearing in JAMA, found that those undergoing gastric bypass operations lost more weight – an average of 66 percent of their excess weight, compared to 45 percent average excess weight loss for those undergoing gastric banding procedures. “We know gastric bypass brings more weight loss success and relief of commonly associated illness versus gastric band at one year after surgery. We now have the best evidence available telling us this outcome continues to be true even up to five years after surgery. We also know these procedures maintain their safety profile long-term,” said Dr. Nancy Puzziferri, Assistant Professor of Surgery and part of the bariatric surgery team at UT Southwestern. According to a 2011 estimate, some 120,000 bariatric procedures are performed annually in the U.S. Worldwide, gastric bypass accounts for about 47 percent of weight loss procedures, while gastric bands account for about 18 percent.
