Fatty Liver
Fatty Liver
By Dr. Lee Ser Yee
Fatty liver also known as Non-Alcoholic Fatty Liver Disease (NAFLD) is a condition in which fat builds up in your liver that is not caused by drinking alcohol. This can lead to inflammation and damage to the liver called Non-Alcoholic Steatohepatitis (NASH).

While excessive alcohol can lead to fatty liver (Alcohol-Related Fatty Liver Disease), in many cases it does not play a role.


It is associated with obesity and a lack of exercise. It forms part of a metabolic syndrome that includes diabetes mellitus, obesity, high cholesterol and hypertension – all of which increases the risk of cardiovascular events such as a heart attack or stroke.

How do I know if I have it?

Most people with fatty liver disease do not know they have it. There are usually no symptoms till late. Your doctor can do tests to check your liver’s health.

  • Blood test- e.g. Liver function test, Lipid panel, Hepatitis panel, Diabetes panel
  • Radiology - e.g. US, CT, MRI, Fibroscan, Magnetic resonance elastography
  • Liver biopsy – if indicated

It is treated with a healthy balanced diet, regular exercise, and weight loss. Weight loss surgery may be helpful in more severe cases.


Exercising regularly and keeping a healthy weight are important. Your doctor may recommend screening for hepatitis and vaccination against hepatitis A and B. Limitation of alcohol intake is important as well.

What else should I know?

Most people with fatty liver will not get chronic liver disease (fibrosis or cirrhosis) if the condition is mild or well- controlled. Fatty liver in its early phases can be reversed with simple lifestyle changes such as healthy diet and regular exercise. However, if it progresses or worsens, it can lead to more serious problems such as liver damage and increased risk of liver cancer.

Seek a liver doctor early to learn more.
