which is a stool with a trace. what could be the reason for this?
i have no blood in the stool.
sometimes i have itch rectum, and maybe i have an internal hemorrhoid.

Hi, it is difficult to tell the exact cause for the bleeding without examining. Haemorrhoids (piles) is the commonest cause for painless bleeding into the stool. Another cause is fissure in ano, where there is pain while passing motion with bleeding. Other causes are inflammatory bowel disorders like ulcerative colitis and crohn’s disease can produce similar symptoms. With a past history of hemorrhoids it could most probably be due to this. If your symptoms persist, would advise you to consult a primary care physician. Regards.
