Hazardous Alcohol Use in the Four Years Following Bariatric Surgery.

The purpose of this study was to estimate the prevalence of hazardous drinking in the four years after bariatric surgery and investigate whether there are differences between those undergoing Roux-en-Y gastric bypass and sleeve gastrectomy. Participants (N = 564) who underwent bariatric surgery between 2014 and 2017 completed a survey regarding post-surgical alcohol use. The rate of alcohol use following bariatric surgery was significantly higher among those between 1- and 4-years post-surgery compared to those less than 1-year post-surgery. Of those who were consuming alcohol at the time of participation, 16.1% had scores indicative of hazardous drinking. The rate of hazardous drinking among those 3-4 years post-surgery was greater than those less than 1-year post-surgery with 33.3% of patients engaging in hazardous drinking at 3-4 years post-surgery. Patients undergoing sleeve gastrectomy had similar rates of hazardous drinking as RYGB (16.3% vs. 15.7%). Thus, findings showed that rates of hazardous drinking were higher among those further removed from bariatric surgery and patients undergoing sleeve gastrectomy appeared to have similar rates of hazardous drinking as those who underwent RYGB. Results suggest a need for monitoring of alcohol use for all patients pursuing bariatric surgery, regardless of surgery type.
