The short answer
What does decompensation feel like?
Decompensation is when a liver with cirrhosis can no longer keep up, and it usually shows as a swelling belly, yellow eyes, confusion or sleepiness, or bleeding. Vomiting blood, black stools, new confusion, or fever with a swollen belly mean go to hospital today.
It often creeps in, then arrives suddenly
Many people notice small things first. Trousers feel tight, ankles swell by evening, appetite fades, or a parent starts mixing up names and sleeping through the afternoon. Families often put these down to age, tiredness or the heat. Then something tips the balance, such as an infection or a bleed, and the person becomes unwell within a day.
Who this page is for
This page is for people who already know they have cirrhosis, with or without liver cancer, and the family members who look after them. If you are not sure what the two stages mean, start with compensated versus decompensated cirrhosis. If your cancer spread to the liver from somewhere else and the liver itself is not scarred, these signs can still matter, but the causes are often different, so ask your oncologist.
A change you notice at home is worth reporting even if it seems small. Families usually see it before the doctor does.

Go to hospital today
Go to the nearest emergency department today, by ambulance if needed, if someone with cirrhosis vomits blood or material like coffee grounds, passes black tarry stools, becomes newly confused, very drowsy or hard to wake, or has a fever or belly pain with fluid in the abdomen. Sudden jaundice with fever also needs hospital today. Say they have cirrhosis. Do not wait for the morning or a routine appointment, and do not give sleeping tablets or painkillers first.
Not sure whether this applies to you?
Ask an oncologistWhat to watch for
What are the signs that the liver is struggling?
Four signs define decompensation. Two more often travel with them and are easy to overlook.
A swelling belly
Fluid called ascites collects in the abdomen. It feels heavy and tight, can make breathing harder when lying flat, and often comes with swollen feet. Weight goes up even as the face and arms get thinner. Read first signs of fluid building up.
Bleeding
Swollen veins called varices can burst in the food pipe or stomach. This shows as vomiting blood or passing black, sticky, foul-smelling stools. Bleeding gums and easy bruising are slower warnings that the liver is making fewer clotting proteins.
Confusion and sleepiness
Hepatic encephalopathy happens when toxins the liver should clear reach the brain. It starts with forgetfulness, poor handwriting, mood changes and sleeping by day, and can move to drowsiness and coma.
Yellow eyes and skin
Jaundice comes with dark urine, pale stools and itching. In cirrhosis it usually means the liver is under real strain, and with a liver tumour it can also mean a blocked bile duct.
Less obvious signs
- Passing much less urine, a sign the kidneys are affected
- Fever, chills or feeling unwell with no clear cause
- Losing muscle and strength, especially in the thighs
- Much less appetite and early fullness

Getting help
What should the family do, and what will the hospital do?
Keep a list ready
Keep a single sheet with the diagnosis, the medicines and the name of the treating doctor. Take it with you, along with recent reports, so the emergency team does not have to guess. An emergency plan for the fridge helps.
Go to the nearest emergency department
For a bleed or new confusion, the closest hospital with an emergency department is better than a long drive to a familiar one. Say the words cirrhosis and liver cancer at the desk.
What the hospital usually checks
Blood tests for bleeding, kidneys and infection, a check of the fluid with a small needle, and often an endoscopy to find and band a bleeding vein. Treatment depends on what they find.
Tell the cancer team
Once the emergency is settled, let your oncologist know. A decompensation episode often changes which liver cancer treatment is safe next, and the tumour board will want to review it.
Commonly believed
What do families often believe about these signs?
"He is just old and forgetful, it is nothing to do with the liver."
In someone with cirrhosis, new forgetfulness, irritability or a reversed sleep pattern can be the liver affecting the brain. It is often triggered by constipation, infection or a bleed, and it usually improves with treatment. Read early signs families notice first.
"The black stools are from the iron tablets."
Iron can darken stools, but sticky, tar-like, foul-smelling stools in someone with cirrhosis may be blood. Do not wait to find out. Go to hospital and let the doctors decide.
"A herbal liver tonic will settle the swelling."
A cirrhotic liver is especially easily harmed by some herbal and Ayurvedic products. Bring anything you are taking to the doctor and say how long you have used it. Nobody will judge you for telling them.
"We should stop protein so the confusion does not come back."
That was old advice and it has changed. Cutting protein weakens the muscles that people with cirrhosis need. Salt is what is usually reduced when there is fluid. Ask the doctor or dietitian before changing food.
Being straight with you
What this page cannot tell you
It cannot tell you whether a sign you are seeing right now is dangerous. Only a doctor who examines the person and checks the blood can do that. When in doubt, treat it as urgent. Going to hospital for something that turns out mild is far better than waiting at home through a bleed.
It cannot tell you what the episode means for the future
Some people recover well from a first decompensation, especially when the cause is treated. Others find the liver stays fragile. Your hepatologist and oncologist will look at the whole picture before giving a view, and nobody can predict it from one episode.
Who this does not apply to
If you have liver cancer without cirrhosis, or cancer that has spread to the liver from another organ, some of these signs can still appear, but the causes and the urgency may differ. Ask your own team which signs matter most for you. Hepatology care, endoscopy and fluid drainage are arranged through CION's partner hospitals and hepatologists.
If you are unsure whether to go in, call the helpline and describe what you see. If it sounds urgent, you will be told to go straight to hospital.Questions we are asked
Common questions about decompensation
What are the first signs of liver decompensation?
Often a slowly swelling belly, puffy ankles, tiredness and less appetite. Some people first show mild confusion or sleep in the day and lie awake at night. Others go straight to a sudden bleed. Any new change in someone with cirrhosis deserves a call to the doctor.
Is vomiting blood always an emergency?
Yes, in someone with cirrhosis. It may be a burst vein in the food pipe, which can bleed heavily and quickly. Call an ambulance or go to the nearest emergency department now. Read vomiting blood: call an ambulance now.
Why is fever with a swollen belly so serious?
The fluid in the abdomen can become infected, a condition called spontaneous bacterial peritonitis. It can make the person very ill quickly and harm the kidneys. Sometimes the only signs are mild pain, a low fever or new confusion. It needs hospital the same day.
Can confusion from the liver be treated?
Usually, yes. Doctors look for the trigger, such as constipation, infection, bleeding or a medicine, and treat it. Lactulose is commonly used to clear toxins through the bowel. Do not give sleeping tablets to calm the person, because they can make it worse.
Does decompensation mean the cancer has grown?
Not always. It can come from the cirrhosis alone, from an infection or bleed, or from a tumour growing or pressing on the veins. A scan helps tell these apart. Your oncologist will usually want a fresh scan after an episode.
Can liver cancer treatment continue after an episode?
Sometimes, once the liver settles. The team rechecks liver function before deciding. Treatments that strain the liver may be paused or replaced with gentler options or symptom care. The reasons are covered in why Child-Pugh decides what treatment you can have.
How can we lower the chance of another episode?
Take the prescribed medicines regularly, keep the bowels moving, limit salt, avoid alcohol and painkillers like ibuprofen, and weigh yourself regularly if you have fluid. Keep endoscopy and surveillance appointments. Ask before starting any new medicine or herbal product.
Who should we call at night?
For bleeding, new confusion or fever with fluid, do not wait for a call back. Go straight to the nearest emergency department. For slower changes, call the CION helpline or your treating doctor the next day. One helpline serves every CION centre.
