Black stools: Although this may be the result of something you have eaten it also suggests the probability that you are bleeding somewhere in your GI tract. Please go now and see a gastroenterologist and have this evaluated. Do not wait to see what is happening. This could become severe. Good luck and hope you are better soon.

HMMM: I do not know, but a black stool could mean blood was in the stool. Best to have a black stool evaluated if it persists.
