Non-alcoholic fatty liver disease (NAFLD) is a long-lasting condition that is caused by a build-up of fat in the liver.
The vital organ is responsible for more than 500 functions, including converting food into energy and removing toxins from the blood. Any problems with the liver, therefore, can be dangerous.
A healthy liver should contain little or no fat, but the British Liver Trust warns that NAFLD affects up to one in five people in the UK.
As the name suggests, NAFLD is not caused by alcohol, it is often linked to obesity and having type 2 diabetes.
In its earliest stages it often doesn’t display symptoms making it hard to catch.

Every year over 4,000 people in the UK die from cirrhosis, which causes the liver to become shrunken, scarred and lumpy.
The NHS says: “This damage is permanent and can lead to liver failure (where your liver stops working properly) and liver cancer.”
If someone has cirrhosis they are more likely to experience symptoms, such as loss of appetite.
