- Bleeding due to hemorrhoids (piles) usually happens at the end of bowel action, is painless and 'Bright Red'.
- Bleeding due to anal fissures may be mixed with stool or may 'streak' the stool.
- Bleeding from higher up in the large bowel may be maroon coloured - what is at times called as 'Hematochezia'.
- bleeding from much higher up in the intestinal tract appears black, tarry, sticky & foul smelling (melena).
I suggest that you see a surgeon, who will perhaps perform a DRE(digital rectal examination) as well as a proctoscopy and sort out your symptom. Best wishes!
