Effect on Women. Research suggests that for women, the most serious risk factor for injury from domestic violence may be a history of alcohol abuse in her male partner.

Effect on Children. Alcoholism in parents also increases the risk for violent behavior and abuse toward their children. Children of alcoholics tend to do worse academically than others, have a higher incidence of depression, anxiety, and stress and lower self-esteem than their peers. One study found that children who were diagnosed with major depression between the ages of six and 12 were more likely to have alcoholic parents or relatives than were children who were not depressed. In addition to their own inherited risk for later alcoholism, one study found that 41% of children of alcoholics have serious coping problems that may last their entire life.

Adult children of alcoholic parents are at higher risk for divorce and for psychiatric symptoms. One study concluded that the only events with greater psychological impact on children are sexual and physical abuse.

Researchers are finding common genetic factors in alcohol and nicotine addiction, which may explain, in part, why alcoholics are often smokers. Alcoholics who smoke compound their health problems. More alcoholics die from tobacco-related illnesses, such as heart disease or cancer, than from chronic liver disease, cirrhosis, or other conditions that are more directly tied to excessive drinking.

Liver Disorders

Alcoholic Hepatitis and Cirrhosis. Alcohol is absorbed in the small intestine and passes directly into the liver, where it becomes the preferred energy source. The liver, then, is particularly endangered by alcoholism. In the liver alcohol converts to toxic chemicals, notably acetaldehyde, which trigger the production of immune factors called cytokines. In large amounts, these factors cause inflammation and tissue injury.

Cirrhosis is a chronic liver disease that causes damage to liver tissue, scarring of the liver (fibrosis; nodular regeneration), progressive decrease in liver function, excessive fluid in the abdomen (ascites), bleeding disorders (coagulopathy), increased pressure in the blood vessels (portal hypertension), and brain function disorders (hepatic encephalopathy). Excessive alcohol use is the leading cause of cirrhosis.
