[|AI|]  Welcome to Chat Doctor, I have gone through you query and understood your concerns, most stools changes have a little meaning, its could be due to some medicine (iron supplements, Pepto-Bismol) food coloring or food additives (black Licorice, Oreo cookies, grape juice, iron-rich food such as spinach and beets) bile, dark green stools can be mistaken for black under poor lighting (Smearing a piece of stool on white paper and looking at it under a bright light often confirms that the color is dark green, another cause is a bleeding in the upper intestinal tract (stomach ulcers and gastritis) I kindly suggest to monitoring if one of the mention above apply to your daughter, anyway a doctor should be consulted to running a few tests to discard a Real bleeding and avoid further complications. Please kindly rate if my advice has been helpful Wishing you a good health Chat Doctor.
