A member asked:

Lately i have black stool after running, even if it's just a one mile run. colonoscopy and endoscope are clean. what would cause the black stool?

A doctor has provided 1 answer

Blood-other causes: Black stool ( melena) can be caused from old blood in the stomach/intestines, . Licorice ( black) can also cause this. Call your physician for upper endoscopy results and photos, get routine blood testing.Defintely do not ignore!
