Alcoholic liver disease is a spectrum of liver damage caused by chronic alcohol use. It ranges from fatty liver to alcoholic hepatitis and eventually cirrhosis. The liver processes alcohol as a toxin, and repeated exposure leads to inflammation, scarring, and loss of function.
Chronic alcoholism refers to long-term heavy drinking that impacts physical health, mental wellbeing, and daily functioning. Heavy drinking is defined as more than 8 drinks per week for women or more than 15 drinks per week for men. Over time, alcohol affects not just the liver but also the brain, heart, pancreas, and immune system.
The liver has remarkable healing capacity in early stages. Stopping alcohol consumption can reverse fatty liver and prevent progression to more serious disease. However, advanced scarring or cirrhosis causes permanent damage that requires ongoing medical management.
