Alcohol-related liver disease (ARLD), also called alcoholic liver disease, develops when years of heavy drinking overwhelm the liver's ability to process alcohol. The liver treats alcohol as a priority toxin to clear, and every time it does, some liver cells die. The liver can normally regenerate itself, but sustained heavy drinking eventually outpaces that ability to repair.
An estimated 68% of Americans drink alcohol regularly, and about 8% drink excessively. Among people who drink heavily over a long period, most will develop some degree of alcoholic fatty liver.
Left untreated, ARLD can progress from fat buildup to inflammation and scarring, eventually reaching an irreversible stage that can be fatal. Because early damage often causes no symptoms, the disease can advance for years before anyone notices.
