The Long-Term Effect of Weight-Loss Surgery on Type 2

By Miriam E. Tucker , , ,


Weight-loss surgery benefits some people with type 2 diabetes who are overweight or obese, but for how long? In a study, 120 such individuals all received lifestyle counseling and necessary medications, while half also underwent gastric bypass surgery. Researchers followed up to see how many reached all of three targets: an A1C (a measure of glucose control over the past two to three months) of less than 7 percent, LDL (“bad”) cholesterol below 100 mg/dl, and systolic (top number) blood pressure below 130 mmHg. After one year, 50 percent of participants who had bariatric surgery had hit all three goals versus just 16 percent of those who didn’t undergo surgery. But after five years, those numbers had dropped to just 23 percent and 4 percent, respectively. The researchers theorize that loss of beta cells may be behind the decline.
