Research indicates that patients undergoing bariatric surgery face a six to seven times higher risk of developing alcohol use disorder (AUD) compared with the population of obese individuals not undergoing surgical intervention. Studies suggest that problematic alcohol consumption encompassing depression escalates gradually after surgery.
The purpose of this study was to evaluate the impact of bariatric surgery on the incidence of AUD and depression during the postoperative period.
Prospective study that evaluated 68 patients who underwent either sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). The presence of AUD and depression was assessed both pre- and post-operatively. AUD assessment utilized the AUD identification test-C score, whereas depression assessment employed the Beck Depression Inventory (BDI).
The average age of the sample was 42.81±9.28 years, with 85.3% being female. The mean follow-up was 16.54±7.41 months. In the preoperative assessment, 92.6% of the sample fell into the low-risk category for AUD. No significant difference was observed between the RYGB and SG groups. Postoperatively, 89.7% of the sample was classified as low risk for AUD, with no significant differences compared with the preoperative assessment. Regarding depression, there was no significant difference between pre- and post-operative periods for all patients. However, a notable trend toward a reduction in “severe depression” was observed in the postoperative period for patients undergoing SG (pre: 14.0% vs. post: 7.0%, p=0.013).
There is no significant difference in the presence of AUD and depression between pre- and post-operative assessments in patients who have undergone bariatric surgery.
Bariatric surgery has been an alternative when conservative methods of weight loss fail. Patients undergoing bariatric surgery have an increased risk of up to 6.5% of problems related to alcohol.
To review the literature about the changes on alcohol consumption in this public.
Database was accessed from June of 2015 to January of 2016 by searching “bariatric surgery” AND “alcoholism”, and their Portuguese equivalents. Science Direct, PubMed, Lilacs and Medline, besides manual search, were searched. To be included, the paper should have been published between 2005-2016 and related to bariatric surgery and alcoholism. Theses, dissertations, unpublished papers, case reports and theoretical studies were excluded. In 2005 there was only one review of change in alcohol metabolism in patients undergoing bariatric surgery. There were no publications in 2006. In 2007, only one study was published, and it did not meet the inclusion criteria. In 2010, there was an increase of 13% in publications and of 20% in 2012, reaching 40% in 2013.
The prevalence and incidence of alcohol consumption in relation to the postoperative time was six months to three years with higher incidence in men. Roux-en-Y gastric bypass showed greater association with increased alcohol consumption during the postoperative period. This and other studies showed that the pattern of alcohol consumption is important to be faced as a problem in bariatric surgery follow-up.
