Hi there and thank you for the question. I am a Registered Nurse and will be happy to help you today.

Have you eaten anything dark in color such as dark chocolate or a piece of cake or other treat that had dark colored icing?

Have you taken any Pepto Bismol lately?
Customer: replied 3 years ago.

No change in diet, no dark foods. No Pepto.


Okay thank you for the added information.

I need to also mention that blueberries and iron supplements can also cause a black stool. However, in your case, if you have had no dietary changes, along with your other symptoms, you may have Ulcerative Colitis or other bowel disease such as Diverticulitis where you are having some possible bleeding. Black stool is indicative of old it could be occurring in the large intestine but with you being constipated somewhat, it could be having a chance to turn dark before ever exiting. Another thought is the possible bleed could be occurring up a little higher such as with an ulcer in the small intestine or stomach. Either way, with your current symptoms, I would at least let the Dr confirm that it is blood and then find out where it's coming from. Not what you want to hear I'm sure, but better to get things checked out.

OK. It's more like a black diarrhea, so that doesn't sound good. I just need to confirm that it's blood and not something else in it. Isn't there some kind of test stick to do that?

Diarrhea or formed stool...doesn't really matter as long as it's black. The blood does need to be ruled out. There is a test that can be done called a FOBT (fecel occult blood test) where some of the black stool is placed on a card and chemicals are then placed on top of that. Depending on what color changes there are, will depend on whether or not blood is the cause here.
