Possibly.: Green stool can be related to the foods we eat. If green and runny it may be due to transitting the GI tract too quickly. If black and tarry with a foul odor - that would be a cause to worry as that could be related to GI bleeding. Black stools can also be due to certain medications (notably pepto bismal). Regardless, changes to stool habitus warrant assessment.

Possibly melena?: Dark-colored stools may result from iron supplements, foods you eat (like a lot of spinach), substances (like peptobismol), but most significantly suggests bleeding. When blood is denatured by acid in your stomach, as from ulcers, stools will turn tarry ("melena"). Blood may also be ingested from nose bleeds, bleeding gums... Persistent melena (without obvious cause) & symptoms warrants md visit.
