Now that weight loss surgery has been popular for some time, and shows no sign of waning, we’re learning about side effects, both long- and short-term. One common finding has been that patients who fail to address their food addiction before going under the knife often replace it with another form of addiction—drugs, alcohol, shopping—once their eating capacity has been surgically limited. A new study, though, has offered a fascinating scientific insight into weight-loss surgery recipients’ relationship with alcohol: physiologically speaking, the procedure doubles the amount of alcohol entering the bloodstream after a drink. This means booze has twice the instant effect, additionally increasing the patient’s risk for binge drinking, and long-term alcoholism. Experts say that these findings only apply to the Roux-en-Y gastric bypass form of bariatric surgery—not the lap band, a less invasive measure—so if you’re considering weight loss surgery and concerned about addiction issues, you may want to ask your doctor about that route.
