Excess alcohol consumption can lead to alcohol-related fatty liver disease (ARLD) because alcohol increases fat levels in your liver. Research suggests that increased fat may be due to the waste products in alcohol that cause the liver to produce more fatty acids.

If you reduce your alcohol intake or stop drinking, your liver can repair itself. However, if you keep drinking excessively, your liver may become inflamed, and over the years, permanent liver scarring (cirrhosis) may occur, leading to liver failure.

Being obese or overweight can cause fatty liver disease (non-alcoholic fatty liver disease, NAFLD). Other risk factors for NAFLD include:

NAFLD can also cause permanent liver damage if left untreated for several years.
