Irritable Bowel Syndrome. Irritable bowel syndrome is a disorder characterized most commonly by cramping, abdominal pain, bloating, constipation, and diarrhea. IBS causes a great deal of discomfort and distress, but it does not permanently harm the intestines and does not lead to a serious disease, such as cancer. Most people can control their symptoms with diet, stress management, and prescribed medications. For some people, however, IBS can be disabling.

Irritable bowel syndrome, also referred to as IBS, causes your intestines to contract slower or faster than normal. Due to the difference in the way your bowels constrict, this can cause your large intestine to create gas, pain, cramping and sudden bouts of diarrhea or constipation. Your symptoms may be more severe at certain times, depending upon diet and other lifestyle factors.
