Cirrhosis

Definition

Cirrhosis is a condition that causes irreversible scarring of the liver. As scar tissue replaces normal tissue, blood flow through your liver is affected. This makes it increasingly difficult for your liver to carry out essential functions, such as detoxifying harmful substances, purifying your blood and manufacturing vital nutrients.

Cirrhosis rarely causes signs and symptoms in its early stages. But as liver function deteriorates, you may experience fatigue, nausea, unintended weight loss, and swelling in your legs and abdomen. In time, jaundice — a yellowing of your skin and the whites of your eyes — and intense itching can develop. You may also experience bleeding from your digestive system that could be severe.

Excessive use of alcohol and chronic infection with the hepatitis C virus are the leading causes of cirrhosis. But other factors — including damaged bile ducts, immune system problems and prolonged exposure to certain environmental toxins — can cause liver scarring, too.

Although liver damage from cirrhosis is irreversible, the disease usually progresses slowly and symptoms are often controllable. Specific treatment for cirrhosis depends on the underlying cause, but anyone with cirrhosis must avoid alcohol and other substances that harm the liver. When damage is so severe that liver function is seriously impaired, a liver transplant may be the only option.
