I have blood in my stool it's moderate sometimes it is there some time it is not. It is not pile or any thing as such, I do not have any issues during bowel movements, they are painless and smooth. Moreover, I faced the same situation about five years ago but neglected it, later after a colonoscopy, it was found that there was a polyp somewhere in my colon which was taken out after a surgery in max hospital delhi. However last time I consistently passed blood whereas now it is occasional, almost 30% blood and the rest blood. I have been observing this from the last two weeks ir so. I am a 16 year old boy.
