Childhood Antibiotics Linked to IBS Risk
20 Oct
Summary
- Childhood antibiotic use tied to higher IBS likelihood.
- Odds of IBS increase with more antibiotic prescriptions.
- Study found 10% of 24-year-olds had IBS.
A recent study suggests a potential connection between antibiotic use in childhood and an elevated risk of developing irritable bowel syndrome (IBS). Researchers in Sweden tracked antibiotic prescriptions for over 2,800 individuals from childhood through early adulthood.
By the age of 24, approximately 10% of participants had been diagnosed with IBS. Those who had received antibiotics showed a 1.5 times higher likelihood of having the condition. This risk appeared to grow with the frequency of antibiotic prescriptions, with individuals receiving six or more prescriptions facing nearly double the odds of developing IBS.
While these findings, presented at UEG Week 2026, provide supporting evidence for a link, they do not establish a direct cause-and-effect relationship. Experts stress that antibiotics remain crucial for treating bacterial infections and should not be withheld when necessary. However, the research underscores the importance of judicious antibiotic prescribing practices to avoid unnecessary exposure.
