Massive Genetic Study Finds New IBS Causes

A new genetic study, the largest of its kind with 2.8 million participants, identified 120 gene variations linked to IBS risk. Published in *Nature Genetics* by lead author Daniel F. Andrew, the findings suggest the gut and brain are equally crucial in IBS pathology. This research shifts the understanding of IBS from purely gut or brain-driven to a significant gene-environment interplay.
