Researchers presenting at UEG Week 2026 report that antibiotic use from childhood through early adulthood is associated with higher odds of irritable bowel syndrome (IBS) at age 24. The reported likelihood of IBS rises with the number of antibiotic prescriptions, according to the study findings summarized across outlets.
The coverage comes from Medical Xpress and multiple PR Newswire releases in different languages, all pointing to the same UEG Week 2026 presentation and the same age point (24). While the articles differ mainly in wording and translation, they consistently describe a dose-response pattern—greater antibiotic prescribing correlates with greater odds of IBS. The reports do not indicate that the study establishes causation; they describe an association between antibiotic exposure and later IBS outcomes based on the data analyzed by the investigators.
Overall, outlets frame the results as new evidence connecting early-life antibiotic exposure with gastrointestinal health in young adulthood.
