3rd DIVA report: IBD and Alcohol: a Review of Current Scientific evidence
We are proud to share the third DIVA report, the complex relationship between alcohol and inflammatory bowel disease (IBD), highlighting that while overall alcohol consumption in IBD patients mirrors the general population, it can worsen symptoms, increase intestinal permeability, alter gut microbiota, and interfere with medications—even during inactive disease.
Effects vary depending on individual sensitivity and drink type, with moderate red wine potentially less harmful, while spirits, beer, and white wine may pose greater risks. Other components, such as sulfites and sugar, can also trigger digestive symptoms. Evidence shows alcohol intoxication may increase the risk of developing IBD, particularly Crohn’s disease, and genetic factors may influence susceptibility.
Practical recommendations include avoiding alcohol during active flares, alternating drinks with water, and discussing alcohol use with healthcare teams to tailor guidance to each patient’s disease profile, promoting safer, personalised management and improved quality of life.
