I've had to open a new topic, because no-one has replied to some comments I recently made on this board. It seems that my theory for one of the causes of IBS is so absurd and untrue that I am either losing my mind or out to make money.I am appealing to all women who find that their IBS disappears during pregnancy.I no longer suffer with IBS because I stopped using all forms of panty-liners and menstruation pads. I now only use tampons. My theory is that perhaps when these pads are attached to underwear, they cover the back passage and allow little air to circulate in this area, creating ideal conditions for yeast (which live naturally in the bowel) to thrive and get out of control and so cause IBS.I can think of no other explanation, other than that I am allergic to these pads. I am not in association with any tampon manufacturers in any way. I am only hoping to help another lady.Obviously, pregnant women will not have to use any form of underwear protection for nine months and I am wondering whether this is the reason why they get temporary relief from IBS. Can anyone relate to this?
