What is the primary characteristic of cirrhosis?

The primary characteristic of cirrhosis is massive scarring and fibrosis of the liver tissue. This condition results from chronic liver damage, which can be caused by various factors such as chronic alcohol abuse, viral hepatitis, or fatty liver disease. As the liver attempts to heal itself, connective tissue builds up, leading to scarring. Over time, this fibrosis disrupts the liver's normal structure and function, ultimately impairing its ability to perform essential tasks like detoxification, protein synthesis, and bile production. The presence of extensive scar tissue is what distinguishes cirrhosis from other liver conditions, highlighting the severity of the damage and the potential for progression to liver failure if untreated.
