Need clinical correlation causes explained

Detailed Answer:
Thank you for asking

I read your question and I understand your concern. Apart from bleeding in upper GI tract other possibilities of dark stools are

- Iron supplements,
- bismuth subsalicylate (Kaopectate, Pepto-Bismol),
-black licorice. Etc.


I would like you to know that Stool comes in a range of colors. All shades of brown and even green are considered normal. Only rarely does stool color indicate a potentially serious intestinal condition.

Stool color is generally influenced by what you eat as well as by the amount of bile — a yellow-green fluid that digests fats — in your stool. As bile pigments travel through your gastrointestinal tract, they are chemically altered by enzymes — changing the pigments from green to brown.

Consult your doctor if you're concerned about your stool color. If your stool is bright red or black — which may indicate the presence of blood — seek prompt medical attention.

I hope it helps. Take good care of yourself and don't forget to close the discussion please.

Regards XXXXXXX
