If it is happening now, stop reading and call an ambulance
Vomiting blood, or vomiting something that looks like coffee grounds, in a person with cirrhosis or liver cancer is an emergency. Call an ambulance now and go to the nearest hospital with an emergency department today. Do not wait to see whether it stops. Do not wait for the morning or for a call back from the clinic. Black, sticky, tar-like stools and sudden fainting mean the same thing.
The short answer
Why is vomiting blood so dangerous with liver disease?
In someone with a scarred liver, blood in the vomit very often comes from burst varices. These are swollen veins in the food pipe or stomach that carry blood under high pressure. When one bursts, it can bleed fast and heavily, and the liver cannot make enough clotting proteins to help it stop.
A bleed like this needs medicines, fluids, blood and an urgent camera test that only a hospital can give. Every minute spent at home is blood lost. That is why the advice is the ambulance, not a clinic appointment and not a home remedy. You can read why varices form in varices explained.
It is not always varices
Stomach ulcers, a tear from hard retching, irritation from painkillers and, less often, bleeding from a tumour can also cause blood in the vomit. You cannot tell these apart at home, and nor can anyone on the phone. The first step is the same for all of them: hospital, today.
A small streak of blood after violent retching is still worth an urgent call. A cupful, or clots, or coffee grounds, is an ambulance.Not sure whether this applies to you?
Ask an oncologistThe first minutes
What should the family do while waiting for the ambulance?
Call for help first
Call an ambulance before anything else. If one will take too long and the person is awake and steady, another adult can drive them while someone sits beside them. Never let them drive themselves.
Keep them on their side
Lay the person on their side so that any further vomit drains out of the mouth and is not breathed in. Stay with them. Do not leave them alone in the bathroom.
Nothing by mouth
Give no food, no water, no tea and no herbal liquid. They may need an urgent endoscopy, which needs an empty stomach, and anything swallowed can be vomited back and inhaled.
Grab the papers
Take the latest reports, the endoscopy findings, the list of every medicine, and the cancer treatment card. Put the medicine strips in a bag rather than trying to remember the names.
Know the signs
Which signs mean bleeding inside, even without much blood?
Bleeding from varices does not always come out through the mouth. These signs matter just as much in a person with liver disease.
Coffee-ground vomit
Blood that has sat in the stomach turns dark brown and grainy. Families often think it is food or medicine. In a person with cirrhosis, treat it as blood until a doctor says otherwise.
Black, sticky stools
Blood digested in the gut comes out black, shiny and tar-like, with a strong smell. This can appear before any vomiting. See black tarry stools.
Fainting or a racing heart
Dizziness on standing, cold sweaty skin, pale lips and a fast pulse can mean blood loss even when nothing is visible.
- Collapse in the bathroom
- Sudden breathlessness
- Feeling cold and clammy
New confusion or drowsiness
Blood in the gut can trigger confusion in people with cirrhosis. A person who becomes muddled or very sleepy also needs hospital today. See confusion and drowsiness.
At the hospital
What should we tell the emergency doctor?
- The liver condition
- Say clearly: cirrhosis, liver cancer, or both. This changes the medicines they start straight away.
- Known varices
- If an earlier endoscopy found varices, or banding was done, say when. Show the report if you have it.
- Cancer medicines
- Name any cancer drug, especially bevacizumab, which raises bleeding risk. Say when the last dose was given.
- Blood thinners and painkillers
- Aspirin, clot-preventing tablets and common anti-inflammatory painkillers all matter. So do herbal tonics.
- Alcohol, honestly
- If the person has been drinking, tell the doctor. It is asked to keep them safe, not to judge them, and hiding it can delay the right treatment.

Commonly believed
Why do families wait, and what is actually true?
"It stopped, so we can see the doctor tomorrow."
Variceal bleeding often pauses and then returns, sometimes more heavily. A bleed that has stopped still needs the hospital today, because the vein that burst is still there.
"Cold milk or a home remedy will settle the stomach."
Nothing taken by mouth stops a burst vein. Food and drink can be vomited and breathed in, and they delay the camera test that can actually stop the bleeding.
"We should call the cancer clinic first."
The cancer team will tell you the same thing: go to the nearest emergency department now. You can let the oncology team know once the person is being treated.
"The big hospital in Hyderabad is better, so we will travel."
During a bleed, the nearest hospital with an emergency department comes first. The person can be moved later, once they are stable, if a specialist centre is needed.
Being straight with you
What this page cannot tell you
It cannot tell you where the blood is coming from, how serious the bleed is, or what the outlook is. Only a hospital team that has examined the person, checked their blood and looked down the camera can answer those questions. Treatment in hospital is explained in what happens in hospital during a variceal bleed.
What CION does and does not do here
CION centres are not emergency departments. Emergency endoscopy and banding are done by hepatologists and gastroenterologists in hospitals with emergency care. Once the person is safe, CION's team can review the cancer plan, adjust treatment and coordinate follow-up through accredited partner hospitals.
Who this does not apply to
A nosebleed that drips down the throat, or red food colouring, can look alarming. If you are truly sure that is all it is, call your doctor today. If you are not sure, treat it as a bleed.
Write the nearest emergency department and the ambulance number on a card and keep it on the fridge.Questions we are asked
Common questions about vomiting blood with liver disease
Should we call an ambulance or drive to hospital?
Call an ambulance, especially if there is a lot of blood, clots, fainting or confusion. Ambulance staff can start care on the way. If an ambulance truly cannot reach you quickly and the person is awake, another adult can drive while someone sits beside them on their side.
How much blood counts as an emergency?
In a person with cirrhosis or liver cancer, any amount of fresh blood, clots or coffee-ground vomit counts. Do not try to measure it. Small bleeds can come before a large one, and you cannot judge blood loss by looking at a basin.
What will the hospital do first?
They will check breathing, pulse and blood pressure, put in a drip, send blood tests and often give blood. Medicines to lower pressure in the liver's veins and antibiotics are usually started. A camera test, an endoscopy, is then done to find and treat the bleeding vein.
Can varices be treated so this never happens again?
The risk can be lowered a great deal. After a bleed, repeated banding sessions and tablets called beta-blockers are commonly used together. Read preventing a second bleed and banding. The risk is never zero while the liver pressure stays high.
Does vomiting blood mean the cancer has got worse?
Not necessarily. Varices usually come from cirrhosis, which many people with liver cancer also have. Sometimes the tumour raises the pressure by pressing on the main liver vein. Your oncologist will look at the scans once the bleeding is controlled and explain what it means for you.
Should cancer treatment stop after a bleed?
Usually it pauses while the person recovers, and some medicines that raise bleeding risk may be changed. This is a decision for your oncologist together with the liver team. Do not restart any cancer tablet on your own after leaving hospital.
Can we give anything by mouth on the way?
No. Give no water, food, tea, milk, herbal liquid or tablets. An urgent endoscopy needs an empty stomach, and anything swallowed can be vomited and breathed into the lungs. Bring the medicine strips with you instead.
Who do we call after the person is safe?
Once the bleeding is under control, call the CION helpline. We will help get the hospital reports to your oncologist, review the cancer plan and coordinate liver follow-up. During the bleed itself, the emergency department comes first.
