What Does Black Stool Signify?
get a stool occult blood test done
Black stool could be a normal variation. But sometimes it could also be due to internal bleeding.
I would suggest that you get a stool test for occult blood done. In case the test is negative then you shouldn't worry about the black color.
In case, it is positive then you need to visit your doctor to investigate the cause of the bleed.
Hope this helps
