What is fatty liver?

Fatty liver refers to a condition in which fat accumulates excessively within liver cells — it is generally diagnosed as fatty liver when fat makes up 5% or more of the liver's weight.

Alcoholic vs. non-alcoholic fatty liver

Alcoholic fatty liver develops from excessive alcohol consumption, while non-alcoholic fatty liver develops from obesity or metabolic abnormalities regardless of alcohol use — and the number of non-alcoholic fatty liver cases is known to be steadily rising.

Usually no symptoms early on

Fatty liver typically causes no noticeable symptoms in its early stages, so it is commonly discovered incidentally through blood tests or an ultrasound during a routine health checkup.

Risk of progressing to hepatitis or cirrhosis

If left unmanaged, fatty liver can in some cases progress to fatty liver-related hepatitis, where the liver becomes inflamed, and if this persists for a long time, it carries a risk of eventually progressing to cirrhosis, where the liver becomes hardened.

The importance of lifestyle changes

Weight loss, regular exercise, quitting or limiting alcohol, and a balanced diet are lifestyle habits generally known to help improve fatty liver. If you have been diagnosed with fatty liver, be sure to consult a doctor to decide on a management plan.

What fatty liver is

Fatty liver is often dismissed as not serious, but if left unaddressed, it can have long-term effects on liver health. This page is provided for general informational purposes — if you have been diagnosed with fatty liver, consult a doctor to decide on a management direction.

Its connection to diabetes

Fatty liver and diabetes are known to influence each other, and improving insulin resistance often helps fatty liver improve as well — so managing blood sugar can also benefit liver health.
