Fatty Liver Disease: Types, Causes and What It Means

What fatty liver is, how the types differ, and why it develops.

Fatty liver disease means fat has built up inside liver cells. It is grouped by cause: the metabolic form — now usually called metabolic dysfunction-associated steatotic liver disease (MASLD), and previously non-alcoholic fatty liver disease (NAFLD) — and the alcohol-related form (ALD, or alcoholic fatty liver disease). The two can overlap.

Early fatty liver often causes no symptoms at all and is picked up incidentally on an ultrasound or a routine blood test. Left unaddressed it can progress through inflammation (steatohepatitis) to scarring (fibrosis) and, in a minority of people, to cirrhosis. The articles below explain the condition itself before getting into what to do about it.
