Thanks for your query.
From the brief details provided, you may be suffering from either of the following conditions :-
* Inflammatory Bowel Disease
* Benign growths- called polyps- in the intestine/colon
* or, a tumour in Colon.
I would recommend that you consult a qualified Gastroenterologist, who will carry out some tests, including, urgent Colonoscopy
to look for the causative lesion inside the colon. He will then reach to a diagnosis and thereafter, brief you what would be best for you.
