IBS that leads to increased diarrhea is often called IBS-D. It is an opposite condition to IBS with constipation (IBS-C).
If you have IBS-D, you have belly pain and other IBS symptoms plus frequent bowel movements. Your stool might be loose, though not always. You also might have sudden urges to use the bathroom.
The exact cause of IBS-D is unknown. But women and adults under 50 are more likely to have it.
