I am wondering if anyone else has this problem? My heart races "before" I have a bowel movement..... I don't know if this is just my bodies way of telling me that I need to have a bowel movement. Then after I have the bowel movement, my heart rate increases even more to the point of severe anxiety and even sometimes panic. It doesn't happen every time I have a bowel movement, but pretty much almost all the time. I do suffer from IBS as well. It's really upsetting to me. It's just awful and so upsetting. Why can't I just be normal??!!
