what may cause blood in the stool? . more importantly what may cause a lot of bright red blood in the toilet after bowel movement and a rather large blood clot? i had to remove myself from the toilet to clean myself and found the blood clot. about the size of a small chicken liver and almost the same consistency. no more bleeding since. bleeding i've experienced before and doesn't concern me but the clot was rather scarey.
the source will need to be found so you will need to see a medical provider for an examination. it could be a fissure (a tiny tear in the anal area) a hemorrhoid (internal or external) a polyp or?
