Spastic colon was an early term used to describe the health condition that is now known as irritable bowel syndrome (IBS).

The term "spastic colon" came about because of a belief that the motility problems and abdominal pain of the disorder we now know 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.

What Causes IBS?

Although no one knows for sure why some people end up with IBS, there is now much more information as to what might have gone wrong. Here are some of the areas that have possibly been identified as being problematic:

  • Motility problems: The functioning of the muscles of the large intestine, including speed and strength of gut contractions.
  • Visceral hypersensitivity: A stronger than normal pain response to pressure within the large intestine.
  • The brain-gut connection: the role of the nervous system, including changes in the levels of neurotransmitters and hormones.
  • Inflammation: Although by definition, there is no visible inflammation with IBS, there are indications that there may be inflammation that is not visible to the eye.
  • Gut bacteria: An imbalance between "friendly" and "unfriendly bacteria that make up the gut flora.

    One of the reasons why IBS is so tricky to understand (and treat!) is that there may be an interplay among some or all of the above factors.  You can see that researchers have come a long way from pointing to spasms in the gut as being the problem!

    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:
