Bloody stool means that there's some sort of injury or disorder located somewhere in your digestive
tract. The closer the source of bleeding is to the anus, the brighter red the blood will be. This is because
the bacteria in your digestive system work to break down the blood as it passes through. So the longer blood
stays in your digestive tract, the darker it will become.
If the bloody stool is bright red, then it could be due to hemorrhoids or anal fissures. The causes of bloody
stool that is more maroon in color is intestinal polyps, inflammatory bowel disease or diverticulosis
