The term "spastic colon" came about because of a belief that the motility problems and abdominal pain of the disorder now known as IBS were caused by muscle spasms within the large intestine. It is now known that the problems inherent in the syndrome IBS go beyond mere spasms. The term IBS was thus coined to offer a broader characterization of the full spectrum of IBS symptoms. If you have been told you have, or just think you have, a spastic colon, it may be helpful for you to learn some basic information about IBS. Irritable Bowel Syndrome IBS is a functional gastrointestinal disorder, meaning that there is something wrong with the way that the digestive system is functioning, yet no visible signs of disease can be seen during diagnostic testing. IBS is diagnosed after your doctor has ruled out other disorders. The subtypes of IBS are based on the changes in bowel movements and whether constipation, diarrhea, or mixed bowel habits are predominant. Symptoms of IBS People who have IBS experience a variety of symptoms related to the functioning of the large intestine. This means that they experience chronic constipation or urgent bouts of diarrhea. Many people find themselves alternating between the two bathroom problems. Other symptoms include: Abdominal painGas and bloatingA feeling of incomplete evacuationMucus in the stool If you are experiencing these symptoms and have not yet been to see a doctor, it is imperative that you do so. Many other more serious disorders share some of these same symptoms. It is important that you receive a proper diagnosis so that you can set up the appropriate treatment plan.
