Definition of Alcoholic liver disease:

Alcoholic liver disease is damage to the liver and its function due to alcohol abuse.

See also: Cirrhosis

Causes, incidence, and risk factors:

Alcoholic liver disease usually occurs after years of excessive drinking. The longer the alcohol use and the more alcohol that was consumed, the greater the likelihood of developing liver disease.

Acute alcoholic hepatitis can result from binge drinking. It may be life-threatening if severe.

People who drink excessively can become malnourished because of the empty calories from alcohol, reduced appetite, and poor absorption (malabsorption) of nutrients in the intestines. Malnutrition contributes to liver disease.

Other factors that contribute to the development of alcoholic liver disease:

• Genetic factors
• Personal susceptibility to alcohol-induced liver disease
• Toxicity of alcohol (ethanol) to the liver

Alcoholic liver disease does not affect all heavy drinkers. Women may be more susceptible than men. It is not necessary to get drunk for the disease to develop.
