Brief Answer:
may indicate bleeding in the upper GI tract in some persons

Detailed Answer:
HI, thanks for using healthcare magic

If stool has a black ground like appearance, then this can sometimes indicate that there may be blood /bleeding in the gastrointestinal tract, in most cases, the upper GI tract.

As blood passes through tract, it mixes and changes and may then have a black appearance. Medications such as iron supplements and pepto bismol may also cause the stool to darken

In some individuals the coffee ground appearance may not be significant but a colonoscopy is a good option to check the colon.
If it is normal, you may need a scope of the upper GI tract

I hope this helps, feel free to ask any other questions
