Irritable bowel syndrome: Controlling symptoms with diet

What is irritable bowel syndrome?

Irritable bowel syndrome (IBS) is a disorder of the intestines that causes abdominal pain or discomfort. The pain may occur alone or along with constipation or diarrhea. Other symptoms include bloating, mucus in stools, or a sense that you have not completely emptied your bowels.

In irritable bowel syndrome, the movement of the digestive tract is impaired but doctors can find no change in physical structure, such as inflammation or tumors. The symptoms of IBS are thought to be related to abnormal muscle contractions in any part of the intestines.

IBS is believed to be caused by increased sensitivity of the bowel. It is not known why some people's intestines are more sensitive than those of other people. Psychological stress and eating may bring on the symptoms. Managing stress and changing your diet are the main treatments for the condition. Medications may be used to treat severe symptoms that interrupt daily activities.
