A member asked:

If i had black grainy stool just one day do i need to go to the dr ? how many days can you have that before you need to be seen?

A doctor has provided 1 answer

Black stool: Unless you're taking iron supplements or peptobismol, I would recommend having your stool checked for occult blood which can be done in a physician's office very easily or by bringing a stool sample to a laboratory if your physician prefers not to examine you. Black stool can signify bleeding from the upper gastrointestinal tract.
