Are you positive it's not just urine?
I don't want to sound disgusting, but when I do wipe it can sometimes take on a yellowish color depending how much and how smeared it is.....on another note (Thank Goodness!) My mother-in-law was supposedly suffering with IBS...needless to say, all tests were proving negative...turned out to be depression and anxiety and started on Lexapro! (anti-anxiety/depression medication). Her IBS went away! Just a thought since you seem to be overly anxious although all tests prove negative....ONE DEFINITE SIGN OF ANXIETY DISORDER!
I really hope its not urine, I'm a guy! I am sure its not urine, sorry I hate talking about gross topics, I have had around 20 liver function tests, over the last two years, and they have never detected any jaundice. So I assume that it probably isn't related to billirubin despositing in the stool.
I do take lexapro, which has helped a lot with the IBS, but not compeletly cured it. On another note, my mom has IBS and I have heard it can be a hereditary condition.
Did you ask the doctor about the yellow toilet paper? I think it is nothing...but CALL HIM to settle your mind!
That is funny about the urine....LOL I was thinking the same thing not realizing that you are a guy. Sorry for the confusion!!!!!!
LOL! Yeah in my case I think there would be something horribly wrong if it where urine. No offense sparkeler, just having some fun. It gave me a good laugh at work. Thank you for your thoughts all. =)
