Irritable bowel syndrome (IBS) is a very common disorder which affects the colon (large intestine). It causes constipation, diarrhea, gas, bloating, abdominal pain and cramping. Irritable bowel syndrome is usually long term. Unlike other disorders like Crohn’s disease and ulcerative colitis, irritable bowel syndrome doesn’t result to colorectal cancer or changes in bowel tissue disorder. Irritable bowel syndrome can be controlled by administering changes in your diet and lifestyle. Some also require counseling and medication.
The exact cause of irritable bowel syndrome is not yet known but studies suggest that a lot of factors play a major role. The intestinal walls are lined with a layer of muscle which contracts and relaxes in a rhythm when they move to your rectum through your intestinal tract. If you acquire irritable bowel syndrome, the contractions can get stronger and last much longer than usual. This causes diarrhea, bloating and gas. In some cases, the opposite can also occur, this can be characterized by weak intestinal contractions, which slows food passage resulting to dry and hard stools.
