Goal of our study is to determine the effect of laparoscopic sleeve gastrectomy (LSG) on alcohol use after surgery. Material and methods. 90 patients (44 men and 46 women), residents of Romania after LSG. The patients were divided into two groups according to the estimates obtained from the AUDIT test (Alcohol Abuse Disruption Test). These patients were examined prior to surgery and 12 months after LSG. Results. Before surgery: 5 (5.5%) patients reported alcohol abuse (AUDIT score of 8 or higher), and 85 patients did not report alcohol abuse (AUDIT scores below 8). 3 patients reported, 12 months after surgery, for persistent alcohol abuse, which they not reported before surgery. 12 months after surgery, the amount of alcohol abuse has changed. The number of patients reporting alcohol abuse increased from 5 (5.5%) to 18 (20%). Thus, with regard to the effect of bariatric surgery on the level of alcohol use, our results showed that 2/5 (40%) of patients who reported alcohol abuse before the operation reduced its consumption to the level of the group without the risk of alcohol abuse. At the same time, 15 (17.6%) patients from the group where there was no risk, 12 months after surgery, increased their level of alcohol intake. Findings. Bariatric surgery may pose a potential risk of increased alcohol use. In addition, the increase in alcohol consumption after surgery can be explained by the ability to satisfy with alcohol, significantly reduced consumption of previously preferred products with a rich taste.
