Does Acid Reflux Cause Black Stool

Black stool can be caused by internal bleeding. When digested blood becomes black. You should have this checked ASAP. For my Mom, black stool and vomit that looked like coffee grinds happened just before she had a severe ulcer. Any amount of bleeding into the intestinal track can cause black stool but a small bleed can become a big bleed quickly. Because you have had reflux for so long and because you've changed your medication and because you are having this new symptom you should be seen ASAP.

P.S. There are other possible reasons for black stool such as taking an iron supplement but with your history you don't want to make any bad assumptions.
