hi angie, I recently got a very quick ibs dx (meaning with very little tests run) I am not sure if I think gastro is right since I have so many other symptoms but that is a whole nother story. you can search my name and read thread from a few days ago on IBS board if curious. I also have exactly what you are talking about. It is not in the bm it looks like white stringy stuff coming off of it, really white and it "cobwebs" through the water. For awhile I thought it was tp but started making sure there was none leftover in toilet before I went and it def is some sort of mucus / tissue. I also have a lot of clear slimy mucus sometimes that is all that passes. Sorry I don't have a real answer for you but I thought I was the only one....I have read peeps with the clear mucus but none like this. I will continue to check and feel free to Pm me.. Maybe if one of us can find and answer than we can steer eachother in the right direction.ps this has been going on with me since march best of luck -Jen
