I had a small amount of fresh blood in my stool. can it be when one exerts! wht should i do.what are probable causes.help.

Hemorrhoid.: A small amount of fresh blood in the stool, especially when seen on the toilet paper, is likely due to a hemorrhoid. This is just a bulging blood vessel that leaks. However, any time you see blood in your stool you should have it checked out by a doctor to be sure. Blood mixed with stool can be a sign of colon cancer or inflammatory bowel disease. But what you describe sounds like a hemorrhoid!
