Black stools can be due to food or alcohol (including red wine) if taken in excess, and this is often harmless if temporary. Iron supplements, certain foods, or medicines can also cause dark stools.If black stools persist or any symptoms appear, consult a doctor and consider CBC + stool occult blood test
If it resolves within a day or two and no symptoms develop, it is usually not serious.
