Obese adults who undergo weight-loss surgery are more likely to survive the next decade than those who don’t. A study in the January 6 JAMA finds that, compared with obese people who had no surgery, patients who elected bariatric surgery had mortality rates roughly half as high 5 and 10 years after the operation.
Earlier research had shown the surgery can induce weight loss, reverse type 2 diabetes in many people and protect against heart problems (SN: 9/10/2011, p. 26
). Some studies also showed lower mortality rates, but those data largely came from women and young to middle-aged adults.
Nearly three-fourths of the patients in the new analysis were men who were, on average, in their early 50s when they got the surgery. “This gives us evidence that even for older patients there is a survival benefit,” and that it
