Alcoholism - Complications

Complications


Alcoholism reduces life expectancy by about 10 - 12 years. The earlier people begin drinking heavily, the greater their chance of developing serious illnesses later on.

Alcoholism and Early Death

Alcohol can affect the body in so many ways that researchers have a hard time determining exactly what the consequences are from drinking. Heavy drinking is associated with earlier death. However, it is not just from a higher risk of the more common serious health problems, such as heart attack, heart failure, diabetes, lung disease, or stroke. Chronic alcohol consumption leads to many problems that can increase the risk for death:

  • People who drink regularly have a higher rate of death from injury or violence.
  • Alcohol overdose can lead to death. This is a particular danger for adolescents who may want to impress their friends with their ability to drink alcohol but cannot yet gauge its effects. However, alcohol overdose doesn't only occur from any one heavy drinking incident, but may also occur from a constant infusion of alcohol in the bloodstream.
  • Severe withdrawal and delirium tremens. Delirium tremens occurs in about 5% of alcoholics. It includes progressively severe withdrawal symptoms and altered mental states. In some cases, it can be fatal.
  • Frequent, heavy alcohol use directly harms many areas in the body and produce dangerous health conditions (liver damage, pancreatitis, anemia, upper gastrointestinal bleeding, nerve damage, and erectile dysfunction).
  • Alcohol abusers who need surgery have an increased risk of postoperative complications, including infections, bleeding, insufficient heart and lung functions, and problems with wound healing. Alcohol withdrawal symptoms after surgery may impose further stress on the patient and hinder recuperation.

Liver Disorders

Alcohol-Induced Liver Disease. Alcohol-induced liver disease (also called alcoholic liver disease) is a spectrum of liver disorders caused by excessive alcohol consumption. Alcohol-induced liver disease includes:

  • Fatty liver
  • Alcoholic hepatitis
  • Alcoholic cirrhosis

Alcohol is absorbed in the small intestine and passes directly into the liver, where it becomes the preferred energy source. The liver 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 of the liver
Cirrhosis is a chronic liver disease that causes damage to liver tissue, scarring of the liver (fibrosis; nodular regeneration), progressive decrease in liver function. Consequences of a failing liver include excessive fluid in the abdomen (ascites), bleeding disorders (coagulopathy), increased pressure in certain blood vessels (portal hypertension), and brain function disorders (hepatic encephalopathy). Excessive alcohol use is the leading cause of cirrhosis.

Fatty liver is an accumulation of fat inside liver cells. It is the most common type of alcohol-induced liver disease and can occur even with moderate drinking. Symptoms include an enlarged liver with pain in the upper right quarter of the abdomen. Fatty liver can be reversed once the patient stops drinking. Fatty liver can also develop without exposure to alcohol, especially in people who are obese or have type 2 diabetes.
