Among adults who have undergone bariatric surgery, the prevalence of alcohol use disorder appears to be greater in the second year after surgery (9.6%) than in the first year after the procedure (7.3%) and the year prior to surgery (7.6%). The following were independently related to increased odds of post-bariatric surgery alcohol use disorders:
Male gender and younger age.
Smoking.
Regular alcohol consumption.
Recreational drug use.
A lower sense of belonging and having undergone a Roux-en-Y gastric bypass procedure also increased the odds of alcohol use disorders after surgery.
