Studies on the impact of alcohol on IBD development have offered rather contradictory results. A 2016 retrospective study involving over 250,000 participants from Taiwan showed that those who had been hospitalized for alcohol intoxication had an increased risk of an IBD diagnosis over a 10-year period. But in 2017, a cohort study in Europe with 262,451 participants found “no evidence of associations between alcohol use and the odds of developing either UC or CD.” A meta-analysis of 16 epidemiological studies also found no significant association between alcohol consumption and the development of Crohn’s disease.
