Off and on GI problems and now coffee grounds in stool?

I agree with the first person, coffee ground looking stool is a GI bleed, usually a upper. When it looks like that it usually means it has been going on for awhile (8 hours) so you may have had this bleeding for at least 8 hours! This can be dangerous. It is something we pick people up for alot in the ambulance, and I would advise you to go to the ER now!
