Alcoholism - Complications

(Page 4)

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 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. [See In-Depth Report #59: Hepatitis.]

Gastrointestinal Problems

Alcoholism can cause many problems in the gastrointestinal tract. Violent vomiting can produce tears in the junction between the stomach and esophagus. Alcoholism poses a high risk for diarrhea and hemorrhoids. It increases the risk for ulcers, particularly in people taking the painkillers known as nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen. It can also cause inflammation of the esophagus (esophagitis), which can lead to bleeding in heavy drinkers.

Alcohol can contribute to serious and chronic inflammation of the pancreas (pancreatitis) in people who are susceptible to this condition. There is some evidence of a higher risk for pancreatic cancer in people with alcoholism, although this higher risk may occur only in people who are also smokers.
