Exactly. I have asked and asked this same thing. And also that's why I put off having surgery do so long. I tried everything, researched everything, but I answer. My surgeon said that they still don't know why it happens in cases like mine and that it is rare. It also is seen more in women than men. I am sure though it has something to do with the brain/gut connection. I was born with a sensitive nervous system and looking back over my life, I am 44, I can see how it would definitely be connected. I am however so thankful that I had the surgery and I am ❤️‍🩹 recovering well. I can now have BMs on my own. It was the right answer for me.
