Could you pick blood out of stool/would it be little pieces or would you think that's food? i eat tomatoes a lot. what would blood in stool look like

Various colors: Make sure by doing a hemocult test. It depends where the blood originates, what the color is. if you are hemocult positive, you may need a colonoscopy. Hopefully it is just your diet. All the best

Red in stool: Red pieces in stool can be tomato. Blood look like it does when you scarp your self or makes the bowel red. i don't think you could peel it off. But though you are young would still get it checked out w/ doc/urgent care.
