What Causes Irritable Bowel Syndrome?

No one knows the exact cause of IBS. What is known is that our modern lifestyles have added to the occurrence and multiplied the number of cases. The walls of the intestines are lined with layers of muscles that contract and relax (peristaltic action) that move food from your stomach through your intestinal tract to your rectum. Normally, these muscles contract and relax in a coordinated rhythm, but for those with irritable bowel syndrome, the contractions may be harder and longer lasting. Food is pushed through your intestines more quickly, causing gas, bloating and diarrhea or sometimes the opposite occurs. Food passage slows, and constipation occurs.

Some researchers feel that irritable bowel syndrome is caused by changes in the nerves that control sensation and muscle contraction in the bowel, though why that happens is still unknown. Those with IBS seem to be more sensitive to the stretching of the bowel with gas that leads to pain and/or bloating. Others believe the central nervous system may affect the colon. Since women are two-three times as likely to have IBS, many researchers now believe that hormonal changes play a role.
