Nonalcoholic fatty liver disease (NAFLD) is the build up of extra fat in liver cells that is not caused by alcohol.
Note: NAFLD is now called Metabolic Dysfunction Associated Steatotic Liver Disease, (MASLD).
NASH tends to develop in people who are overweight or obese, or have diabetes, high cholesterol or high triglycerides. However, some people have NASH even if they do not have any risk factors.
Note: NASH is now called metabolic dysfunction associated steatohepatitis (MASH).
