Childhood Antibiotic Use Linked to Higher Risk of IBS in Young Adults

A new study presented at UEG Week 2026 reveals that antibiotic use from childhood through early adulthood is associated with significantly higher odds of developing irritable bowel syndrome (IBS) by age 24. The research shows a dose-dependent relationship, meaning the risk increases with each additional antibiotic prescription. This finding highlights the importance of judicious antibiotic prescribing in children, as these medications can disrupt the gut microbiome—the beneficial bacteria that support digestive health. The study suggests healthcare providers should carefully weigh the benefits against potential long-term consequences when prescribing antibiotics to young patients.
