17819 Liver Failure
Informed by recognized medical guidance
Overview
Liver failure is a serious condition in which the liver stops working properly. The liver is a large organ that cleans the blood, helps digest food, stores energy, and makes proteins. When it fails, these vital jobs are no longer done, which can be life-threatening without prompt medical care.
Key facts
- Liver failure can happen suddenly (acute) or slowly over many years (chronic).
- The most common causes are long-term alcohol misuse, viral hepatitis, and fatty liver disease.
- Early treatment can slow or sometimes reverse the damage, depending on the cause.
Liver failure itself is not very common, but chronic liver disease affects a large number of people worldwide. It is more often seen in those who already have long-term liver damage.
Liver failure can affect people of any age, but it is most likely in adults who drink too much alcohol, have hepatitis B or C, or have fatty liver disease. Men and older adults are more frequently affected, but the condition can occur at any stage of life.

Causes
Main causes
- Long-term heavy alcohol intake
- Chronic viral hepatitis (such as hepatitis B or C)
- Fatty liver disease, often linked to obesity and diabetes
- Overuse of certain medications or toxic substances
- Autoimmune hepatitis, where the immune system attacks the liver
- Genetic or metabolic disorders that affect the liver
Risk factors
- Drinking excessive alcohol over many years
- Being overweight or having diabetes
- Sharing needles or having unsafe sex that spreads viral hepatitis
- Taking some medicines without medical supervision
- Being exposed to certain industrial chemicals or toxins
When to see a doctor
See a doctor urgently if:
- Go to the emergency department right away if you have jaundice, confusion, vomiting blood, or severe abdominal swelling.
- Call your local emergency number for any symptom listed in the emergency section.
Book a routine appointment if:
- Make a doctor's appointment if you have ongoing tiredness, poor appetite, unintentional weight loss, or persistent abdominal discomfort.
- Also see your doctor if you have risk factors such as heavy drinking or a history of hepatitis and have not been checked recently.
Diagnosis
Your doctor will ask about your symptoms, medical history, and lifestyle habits, then do a physical exam. To confirm liver failure, they will order blood tests and imaging scans. In some cases, a small sample of liver tissue is taken for testing.
Tests that may be done
- Blood tests to check liver enzymes, bilirubin, and clotting
- Ultrasound, CT, or MRI scans to see the liver's structure
- Liver biopsy, where a tiny piece of liver is removed and examined
What to expect at your appointment
If your doctor suspects liver failure, you may be referred to a liver specialist. The tests are usually done in a hospital or clinic. It is helpful to bring a detailed list of your symptoms, all medicines you take, and any questions you have.
Treatment
Treatment for liver failure depends on the underlying cause, how quickly the condition developed, and how much damage has already occurred. In many cases, the goal is to manage symptoms, prevent further damage, and give the liver time to heal. If the liver is very badly damaged, a liver transplant may be the best option.
Self-care at home
- Stop drinking alcohol completely.
- Take only the medicines and doses your doctor recommends.
- Follow a healthy, balanced diet with limited salt.
- Weigh yourself daily to watch for fluid buildup.
- Get plenty of rest and avoid strenuous activity.
Medical treatments
Doctors may prescribe medicines to reduce inflammation, control fluid retention, clear toxins from the blood, or combat infections. Treatments such as nutritional support, vitamin supplements, and procedures to drain fluid from the belly may also be used. In severe cases, the person may need to be cared for in a hospital intensive care unit.
When is surgery considered?
A liver transplant may be recommended if liver failure is severe and other treatments have not worked. This involves replacing the damaged liver with a healthy one from a donor. After a transplant, most people need lifelong medicines to prevent rejection.
Living with this condition
Living with liver failure means regular check-ups and following your healthcare team's advice closely. You may need to take medicines every day, monitor your weight, and watch for any new or worsening symptoms. Keeping a daily symptom diary can help you and your doctor spot changes early.
Lifestyle tips
- Avoid alcohol completely.
- Maintain a healthy weight and stay physically mobile.
- Get vaccinated against hepatitis A and B, if recommended.
- Avoid street drugs and never share needles.
- Inform your pharmacist about all medicines and supplements you take.
Diet and exercise
A liver-friendly diet is one that is low in salt and processed foods, with plenty of fruits, vegetables, whole grains, and lean protein. Strenuous exercise may be too tiring, but gentle walking or stretching can keep your muscles strong and improve your mood. Ask your healthcare team what level of activity is safe for you.
Mental health and emotional wellbeing
Dealing with liver failure can be stressful, frightening, and isolating. It is normal to feel anxious or depressed after a diagnosis. Talk openly with your doctor about your feelings, and ask for help if you are struggling. Counselling and support groups can make a big difference.
Prevention
Many cases of liver failure can be prevented by making healthy choices. Reducing alcohol intake, keeping to a healthy weight, practising safe sex, and avoiding unnecessary medicines all help protect your liver. If you have hepatitis, getting treated early can prevent progression to liver failure.
Vaccines
Vaccines are available for hepatitis A and B. These can protect you from some of the most common infections that cause serious liver damage. Ask your doctor or local clinic if you are eligible for these vaccines.
Screening programmes
People with a high risk of liver disease, such as those who drink heavily or have a history of hepatitis, should have regular check-ups and blood tests. Screening can find liver problems early, when they are easier to manage.
Complications
If left untreated
- A buildup of toxins in the blood that can cause brain damage (hepatic encephalopathy)
- Severe bleeding from enlarged veins in the food pipe or stomach
- Kidney failure
- Infections, such as spontaneous bacterial peritonitis
- Liver cancer
- Death if the failure becomes complete
Long-term outlook
The outlook depends on the cause and how early treatment starts. Some people recover fully after the underlying cause is treated, such as stopping alcohol or managing hepatitis. For those with severe damage, a liver transplant can offer many more years of good quality life. Even in serious cases, there is always hope with the right medical care.
