Addictive behaviour and bariatric surgery: Case report and literature review

Even though the scientific evidence supports the benefits of bariatric surgery, its indications and contraindications must be continually revised in order to avoid psychiatric complications. Substance use is more common in patients subjected to bariatric surgery than in the general population. There are reports of increased incidence of alcohol abuse in patients after bariatric surgery. Objective To review the available evidence, after treat the case of a 50-year-old man with addiction history whose addictive behaviour worsened after undergoing bariatric surgery, with decreased tolerance to alcohol effect and increase of the intake, as well as changes in the graduation of alcohol used (including antiseptic). As a result, a dangerous revolving door that led him to repeated admissions, including Intensive Care Unit. Results The case is consistent with the literature that suggests that there is an increased risk of later alcohol-related problems after bariatric surgery. This risk is higher several years post surgery, in patients with previous history of problems related to alcohol, young, men, and Roux-en-Y Gastric Bypass procedure. Conclusions The indications for bariatric surgery should thoroughly consider the history of addiction, an adequate assessment of the patient's mental status and psychoeducation about the possible psychiatric side effects, in order to develop preventive strategies.
