The simple answer is yes, stress makes irritable bowel syndrome (IBS) worse, but stress makes most things worse. The corollary (natural consequence) is that reducing stress may improve IBS, may also be true. Stress is not believed to be the most important factor causing the discomfort of IBS, however, and, therefore, eliminating or reducing stress-though it might improve IBS-will not eliminate it.
