Hello, Lorraine; thank you for posting.

 

Sometimes, BMs seem to be black, but they are really not; they can be a reflection of a variety of dark products that we recently consumed. Digested cooked spinach, purple grape juice, and beets are good examples.

 

However, truly black stools, also often described as looking like tar, are suspect of upper GI bleeding, as blood, when digested, turns black.

 

If you are concerned that your BMs look black, or tarry, make a "first available" appointment with your doctor. If you are having severe pain as well, you should be seen at an urgent care center, or an E.R.

 

Hope

I have had dark  or black stools for about 4 days.  Now they seem to have a slime on it, also.  They are solid.  I have taken Pyrantel Pamoate for pinworms about 3 days ago.  Should I be concerned?
