What are the causes of IBS?
No one really has an idea why IBS is caused. It is speculated that in a person with IBS, their colon muscles are incredibly sensitive to stimuli such as stress, certain foods, or medications. Usually the muscles in the walls of the intestine relax and contract as food moves through the intestinal track. In people with IBS, food either moves too fast or too slow, causing symptoms that range from minor to severe. Researchers are not sure why the muscles are more sensitive in IBS people than other people.
