Liver failure happens when your liver can no longer function properly. It’s a life-threatening condition and results from cirrhosis — permanent scarring on your liver. But the good news is, many lifestyle changes can reduce your risk of developing several conditions that lead to liver failure.
Liver failure is a life-threatening condition. It’s when your liver can’t function properly and as a result, can no longer support your body.
In most cases, this is something that develops over many years as a complication of advanced liver disease or cirrhosis (extensive scarring of the liver). This is known as chronic liver failure or end-stage liver disease. It can also be sudden, within days or weeks of an incident to your liver — this is acute liver failure, which fortunately is rare.
There’s also an acute-on-chronic liver failure, where a chronic liver disease or cirrhosis takes a sudden, life-threatening turn.
To check your liver health regularly, you can do a liver blood test (formerly known as a liver function blood test or LFT) at home. This test can be useful if you believe you are at risk of fatty liver disease and have persistent symptoms like nausea and fatigue.
But it can’t diagnose or rule out liver disease without further investigation or full medical context.
When doing this liver blood test, your GP will review your:
Often chronic liver failure is the result of cirrhosis. Many different conditions and diseases can lead to cirrhosis and chronic liver failure.
The most common causes of liver failure are:
Acute liver failure is most commonly caused by:

It can take years for chronic liver failure to develop. You’ll typically notice signs of liver dysfunction long before liver failure — like abdominal pain, swelling (ascites), and spider-like blood vessels on your skin.
The most common chronic and acute liver failure symptoms are often the same, including:
A key part of liver failure treatment is to address the underlying cause early to stop your liver function from getting worse and for it to repair itself. This might include:
Liver failure is a severe and life-threatening condition. When your liver fails to function correctly, most treatment options aim to:
Some liver failure treatment options include reducing your salt intake to avoid complications associated with swelling (ascites). And being prescribed beta-blockers to prevent internal bleeding (haemorrhaging) — works by slowing down your heart.
Micronutrient deficiencies are also a big concern in liver failure. The most common deficiencies are vitamin A, vitamin D, vitamin E, vitamin K, and zinc. These can be treated with increased calorie and protein intake. Or you might need to take them in supplement form depending on how ill you are.
If your liver failure is at an advanced stage, or you develop a serious complication, and other treatments don’t appear to work, a specialist might refer you for a liver transplant.
The best way to prevent chronic liver failure is to slow the damage and scarring of your liver or to prevent developing these conditions altogether.
The good news is that lifestyle changes can reduce your risk of developing many conditions that lead to liver failure. This includes the two most common conditions — NAFLD and ARLD.
Manage your weight
The key lifestyle changes that can prevent NAFLD are weight loss if you’re overweight and managing any metabolic conditions you might have, like type 2 diabetes.

Follow a Mediterranean diet
The Mediterranean diet is a great way to reduce your risk of insulin resistance. This involves eating a diet rich in vegetables, whole grains, and unsaturated fats. It’s also linked to reducing fatty deposits in your liver associated with NAFLD.
Reduce your alcohol intake
The key lifestyle change for ARLD is reducing how much alcohol you drink. The damage done to your liver increases the more you drink, which is why the current UK guidelines are to consume less than 14 units a week regularly. This equals 6 pints of beer or 10 small glasses of wine.
Anything that affects the health of your liver has the potential to progress the damage, even if it’s not the root cause of that condition. For example, drinking alcohol and obesity can increase the chance of mortality for all types of liver disease. So managing your weight and reducing your alcohol intake to below-recommended limits can help prevent the development of liver failure from multiple causes.
