What should you know about black coffee ground poop?

Short answer
Black stool resembling coffee grounds can signal digested blood and should receive prompt medical attention, particularly with weakness, pain, or vomiting.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.
At a glance
- Description
- Coffee-ground-like stool is not a precise medical description.
- Possible concern
- Black, sticky, tar-like stool can reflect digested upper digestive bleeding.
- Emergency signs
- Faintness, confusion, severe pain, or blood in vomit need immediate help.
What coffee-ground-like stool may mean
Coffee-ground material is usually discussed in relation to vomit, while stool from digested upper digestive bleeding is more often black, sticky, and tar-like. People may use the phrase to describe dark, grainy stool, but the description cannot determine whether blood is present.
Potential sources of upper digestive bleeding include gastritis, a peptic ulcer, or Helicobacter Pylori infection. These are possible explanations, not conclusions from colour alone. Iron, bismuth-containing medicine, and dark foods can also make bowel movements appear very dark.
What to do now
Arrange prompt medical advice for unexplained black or coffee-ground-like stool, even if it happened once. Record when it appeared, its texture, and whether you have stomach pain, nausea, vomiting, or changes in energy.
Prepare a list of medicines and supplements, including products used for pain or indigestion. A clinician may check your vital signs, blood count, and stool, then decide whether further digestive evaluation is needed.
When this is an emergency
Call emergency services or go to an emergency department for black tar-like stool with faintness, cold or clammy skin, confusion, severe pain, repeated vomiting, blood in vomit, or sudden marked weakness. Do not eat or drink large amounts while waiting for urgent medical instructions.
Questions to ask
Ask whether the appearance could be medicine-related, whether you need blood or stool testing, and whether an ulcer or stomach infection should be assessed. Tell the clinician about previous digestive bleeding and recent pain-medicine use.

Questions people ask
Is coffee-ground stool the same as coffee-ground vomit?
No. Coffee-ground vomit and black tar-like stool are different descriptions, though either can warrant urgent assessment when bleeding is possible.
Can iron make stool look this way?
Iron can darken stool, but it should not be used to explain away tar-like stool or symptoms of illness.
