Black vomit, or "coffee ground vomitus," means there's bleeding in your upper gastrointestinal (GI) tract (esophagus, stomach, small intestine) because the blood has been partially digested by stomach acids, turning it dark brown or black. It's a serious symptom indicating internal bleeding and requires immediate medical attention, often from conditions like ulcers, gastritis, inflammation, or varices, and needs prompt diagnosis and treatment.
Blood in vomit may be bright red, or it may appear black or dark brown like coffee grounds. Swallowed blood, as from a nosebleed or forceful coughing, may cause bloody vomit, but truly vomiting blood usually means something more serious and requires immediate medical attention.
Where black or dark brown vomit indicates partially digested blood, red and pink vomit flags the presence of fresh blood. If you have found yourself vomiting large amounts of red or pink vomit, you must seek medical attention urgently, as this could be a life-threatening emergency.
The color of a person's vomit can vary depending on its cause. While some may be cause for concern, most vomit colors do not indicate a need for medical attention. People may experience nausea and vomiting due to food poisoning, irritation of the gastrointestinal (GI) tract, or as a side effect of certain medications.
Seek medical attention urgently for accurate diagnosis and treatment if your vomit is red, brown, or black colored and accompanied by unsettling symptoms like abdominal pain, chest pain, fever, chills, and signs of dehydration.
The color of bile vomit can provide clues about intestinal obstruction. Greenish bile vomit often indicates a blockage in the intestines.
Possible Causes
Large blood vessels (varices) in the food tube get bigger and bigger over time and can burst open. When this happens, a person may vomit blood or have stool that is black and tarry.
Symptoms
The vomiting may be clear, yellow, or green in mild cases. Blood-streaked or completely bloody vomit may be experienced in acute erosive gastritis cases, usually several days after the onset of the condition.
Nausea and vomiting in palliative care are commonly experienced symptoms, and the aetiology is often multifactorial. The most common causes are impaired gastric emptying, chemical causes (eg medication) and visceral causes (eg constipation).
The color changing to brown or black means the blood has come in contact with stomach acid. “Gastrointestinal bleeding could be the result of a peptic ulcer or a perforation somewhere in your esophagus, stomach or duodenum,” Dr. Capin adds.

Speak to your GP if:
Gastro may cause some or all of the following symptoms:
Six common signs of norovirus include sudden vomiting, watery diarrhea, stomach pain/cramps, nausea, headache, and muscle aches, often appearing 12-48 hours after exposure and lasting 1-3 days, leading to potential dehydration.
Possible causes include gastric ulcers, esophageal varices, gastritis, and more. The amount of time the blood remains in the GI tract before appearing in the vomit will determine its color and shade. A more extended period will result in a darker color, which may be dark red, black, or brown.
Green or yellow colour is caused by bile, which is a fluid made by the liver. Bile in the vomit is usually caused by a blockage or twisting in the intestine or bowel.
As people get closer to dying, they may sleep more, become drowsy or be difficult to wake. They may fall asleep while talking. A person may slowly lose consciousness in the days or hours before death. When visiting someone with advanced cancer, be aware that visiting may be tiring and difficult for the dying person.
This causes a phenomenon called cardiogenic vomiting, where patients experience nausea and vomiting induced by the toxins released as injured cardiomyocytes, the cells that comprise heart tissue, begin to die.
During 1 to 2 weeks before death, the person may feel tired and drained all the time, so much so that they don't leave their bed. They could have: Different sleep-wake patterns. Little appetite and thirst.
Symptoms of a bowel perforation include:
The 3-6-9 rule is a guideline for interpreting abdominal X-rays to detect bowel obstruction, stating normal upper limits are 3 cm for the small bowel, 6 cm for the large bowel (colon), and 9 cm for the cecum; diameters exceeding these suggest dilation, a key sign of obstruction, with larger measurements increasing the risk of rupture (e.g., >6cm small bowel, >9cm cecum).
An obstruction typically feels like severe cramping pain in your abdomen. The pain from a small bowel obstruction is more likely to come in short intermittent waves, occurring every few minutes or so. The pain is more likely to feel concentrated in one place.
