According to a new study, people who undergo weight loss surgery report that they drink more alcohol after the surgery. The study’s 155 participants reported that their alcohol use dropped immediately one month after the surgery, from 61 percent to 20 percent. But by three months, drinking rates had crept up again. Two years after the surgery, people were drinking more than they were before the surgeries.
The drinking increase was primarily the case for people who got gastric bypass surgery, which actually lowers alcohol tolerance so much that one drink can put someone’s blood alcohol content above the legal limit for driving a car. Alexis Conason, a researcher with the New York Obesity Nutrition Research Center at St. Luke’s-Roosevelt Hospital Center, told Reuters Health the alcohol use shouldn’t deter people from having surgery, but doctors should carefully monitor alcohol use afterwards.
