The color and consistency of your stool can reveal a lot about your digestive health. One of the concerning changes you may notice is black-colored poop.

While it is not always a sign of a severe condition, it is essential to understand what may cause black stool and when to seek medical attention.

Here are some reasons your stool may be a black, tarry color.
