Even moderate alcohol intake can produce pain in the upper right quarter of the abdomen--a possible symptom of liver involvement. In many cases, such symptoms may be an indication of fatty liver or alcohol hepatitis, which are reversible liver conditions.

Between 10 - 20% of people who drink heavily (five or more drinks a day) develop cirrhosis, a progressive and irreversible scarring of the liver that can eventually be fatal. Alcoholic cirrhosis (also sometimes referred to as portal, Laennec’s, nutritional, or micronodular cirrhosis) is the primary cause of cirrhosis in the US. It is estimated to be responsible for between 44 - 80% of deaths from cirrhosis in North America. [See In-Depth Report #75: Cirrhosis.]

Not eating when drinking and consuming a variety of alcoholic beverages increase the risk for liver damage. Nevertheless, the amount of alcohol consumed and the patterns of drinking are only weak predictions of risk. Up to 90% of heavy drinkers do not develop advanced irreversible liver disease. Other risk factors have been identified that may increase the danger to the liver in heavy drinkers:

• Obesity is a major factor for all stages of liver disease.
• Women develop liver disease at lower quantities of alcohol intake than men.
• Genetic factors that regulate the immune responses also play role.

Viral Hepatitis B and C. People with alcoholism tend to have lifestyles that put them at higher risk for viral hepatitis B and C, which are caused by viruses. Chronic forms of viral hepatitis pose risks for cirrhosis and liver cancer, and alcoholism significantly increases these risks. People with alcoholism should be immunized against hepatitis B; they may need a higher-than-normal dose of the vaccine for it to be effective. There is no vaccine for hepatitis C.
