Some colors are more worrisome than others. Knowing which colors of stool are dangerous and when to seek treatment can help prevent more serious conditions. Although taking iron supplements or bismuth (the active ingredient in some stomach medications) can darken stool, black, tarry stools may be a sign of bleeding in the upper digestive tract, such as in the stomach or esophagus. If this color is accompanied by a strong odor and abdominal pain, you should see a doctor right away.
