IBS Causes
At present there are still no known precise IBS causes. IBS can seem to come from nowhere, and sufferers often have trouble figuring out why they are afflicted with the condition.
There are a number of theories though that aims to explain IBS causes in terms of physiological disorder which include possibilities such as smooth muscle abnormalities, altered small intestinal mobility, or a sensory condition causing normal mobility of the gut to feel strange and abnormal to a person. However, there is till no real evidence that has been found to support any of these explanations.
There is a possibility though that an overgrowth of bacteria is what causes irritable bowel syndrome. There was a proposal made that suggested that ordinary bacteria normally found in the large intestine may end up in the small intestine giving rise to the characteristic symptoms of IBS; uncomfortable bloating and gas and a change in bowel movements, together with muscle and joint pain, chronic fatigue and headaches which are sometimes found in sufferers. There are about a trillion bacteria in the gut, but are usually scarce in the small intestine, so an increase in bacteria there may account for the symptoms of IBS.
Another more common theory for IBS cause is that it is a stress-related condition. It is most often suggested that stress, anxiety as well as depression can cause IBS, but studies shows that these psychological maladies may only exacerbate the symptoms rather than bring them on. A research made has found the colon muscle of someone with IBS is more sensitive than that of a non-sufferer, which means that IBS sufferers have strong reactions to stimuli that would not affect others. There are also suggestions that hormones may influence symptoms, as women generally have more symptoms of IBS when menstruating.
A third possibility for IBS cause is food intolerance. It is found that different individuals have "trigger" foods which vary widely and sometimes this can only be found out by trial and error in diet, but it is only possible to confirm food intolerance by blood testing for antibodies. Once the trigger foods have been identified by the test, they can then be cut out of the diet, leading to an improvement in IBS symptoms.
