Brief Answer:
bleeding from stomach

Detailed Answer:
Hello.

Thank you for the query.

If the stool was black like a tar, it is a symptom of bleeding from stomach or duodenum. Diarrhea indicates that the bleeding is intense.
Please do not wait with it. Visit your doctor as soon as possible. Gastroscopy is necessary.

Hope this will help. Feel free to ask further questions.
