Patients were recruited between 1987 and 2001. Data on alcohol abuse diagnoses, self‐reported alcohol consumption, and alcohol problems were obtained from the National Patient Register and questionnaires. Follow‐up time was 8‐22 years.</p> </sec> <sec id="oby20397-sec-0003" sec-type="section"> <title>Results</title> <p>During follow‐up, 93.1% of the surgery patients and 96.0% of the controls reported alcohol consumption classified as low risk by the World Health Organization (WHO). However, compared to controls, the gastric bypass group had increased risk of alcohol abuse diagnoses (adjusted hazard ratio [adjHR] = 4.97), alcohol consumption at least at the WHO medium risk level (adjHR = 2.69), and alcohol problems (adjHR = 5.91). VBG increased the risk of these conditions with adjHRs of 2.23, 1.52, and 2.30, respectively, while banding was not different from controls.</p> </sec> <sec id="oby20397-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Alcohol consumption, alcohol problems, and alcohol abuse are increased after gastric bypass and VBG.</p> </sec> </abstract>
