Conditions InDepth: Irritable Bowel Syndrome (IBS)
by Ricker Polsdorfer, MD
Irritable bowel syndrome (IBS) is a chronic disorder of the intestines. It can lead to belly pain, cramping, gas, and bloating. Pain from IBS is often better after a bowel movement.
Causes of IBS
The exact cause of IBS is unknown. Nerves, muscles, air, and movement all help the intestines work smoothly. One or more problems in any of these may lead to IBS. For some, IBS may start after a bacterial infection. It's not known why this happens.
