Why biofeedback would help this problem: The underlying causes of irritable bowel syndrome are unknown for over 2/3 of the people suffering from this disorder. There are two main reasons biofeedback is thought to help IBS. First, stress responses which are expressed as abnormally great gastric reactions (compromised absorption, abnormal muscle contractions related to transport of materials through the gut, etc.) are a key part of the problem for between 1/3 and ½ of the people with IBS. Biofeedback has been shown to be very helpful in teaching people to recognize and control these overreactions. Second, biofeedback recordings can help just about everybody with IBS to recognize when their intestinal tract is about to react abnormally - before they would normally notice symptoms. This knowledge can be used to learn to be aware of when the system is just beginning go get out of wack and to prevent it from doing so.
