Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) is a common disorder of the intestines that leads to crampy pain, gassiness, bloating and changes in bowel habits. Some people with IBS have constipation (difficult or infrequent bowel movements), others have diarrhea (frequent loose stools, often with an urgent need to move the bowels) and some people experience both. Sometimes the person with IBS has a crampy urge to move the bowels but cannot do so.

Living with IBS

The cause of IBS is unknown, and unlikely there ar many causes; as a result, there is no one treatment for everyone. Doctors call it a functional disorder disease because they symptoms result from an oversensitivity of the muscles and nerves and intestine affecting the way in which they function. There is no sign of disease when the colon is examined and, much like a headache or muscle strain, IBS can cause a great deal of discomfort and distress, even thought no structural abnormalities are identified.The good news is that IBS does not cause permanent harm to the intestines and does not lead to intestinal bleeding of the bowel or to a life-threatening diseas, such as cancer.Often IBS is just a mild annoyance, but for some people it can be disabling. they may be afraid to go to social events, to go out to a job or to travel even short distances. Most people with IBS, however, are able to control their symptoms through diet, stress management and, sometimes, with medications prescribed by their doctor.

Through the years, IBS has been called by many names colitis, mucous colitis, spastic colon, spastic bowel and functional bowel disease. Most of these terms are inaccurate. Colitis, for instance, means inflammation of the large intestine (colon). IBS. however, does not cause inflammation and should not be confused with ulcerative colitis, which is a more serious disorder.
