What Causes IBS? Irritable Bowl Syndrome Causes
Unfortunately, we have not pinpointed an exact cause of IBS. In fact, we still really don’t know why some people get IBS and others do not, but one day a single cause might be recognized and a sure found. As far as we can tell, there is no simple infection or other cuase that brings about IBS. What we do know is that the “tuning” of the complex nervous system that controls the gut, called the enteric nervous system(ENS), is involved. When the ENS is badly tuned, the result can be an extra sensitive serve response in the gut and/or abnormalities in how the guy moves and deals with its contents. What actually puts the ENS out of tune and what keeps it out puts the ENS out of tune and what keep it out of tune is largely a mystery.
Factors that Contribute to IBS
1.) Genetic Factors. We know from studies of twins that genes plat at least some role in IBS, and it’s not unusual for IBS to occur within a family.
2.) Gut Infections. When large communities have been infected by a waterborne germ that causes severe diarrhea, many people have later developed IBS )with diarrhea as the main symptom). This is called post infectious IBS.
3.) Stress and Other Psychological Factors. These can affect the ENS by altering how the nerve signals from the gut are transmitted to and interpreted by the brain and spinal cord. The links between the brain and the ENS are collectively called the brain-gut axis. Disturbances in this axis can contribute to IBS and cal also affect anyone.
4.) Abnormal Balances of The Gut Bacteria. Disturbances in the balance of the bacteria that live in the large bowel my contribute to IBS. This is called dysbiosis, and there are different theories about how it might affect the bowel or why it occurs:
- Small Intestinal bacterial overgrowth
- Food-related causes
- Early childhood exposure
5.) Joint Hypermobility. About one in five people has joint hypermobility syndrome. This refers to having joints with greater flexibility, such as being double-jointed or able not only to touch your toes but also put the palms of your hands on the ground. It has recently been found that this condition is associated with a higer chance of having IBS. It is assumed to be relaed to the relative laxness of the tissues in the gut-they tend to distend more, (see bloating and distension). IBS Symptoms.
