Liver cirrhosis is a chronic condition characterized by the gradual replacement of healthy liver tissue with scar tissue, leading to impaired liver function. This scarring disrupts the normal flow of blood through the liver, impairing its ability to process nutrients, produce proteins, and detoxify harmful substances. Common causes include chronic alcohol abuse, viral hepatitis infections, and fatty liver disease. Symptoms may include fatigue, weakness, jaundice, fluid retention, and confusion. Cirrhosis can progress slowly over years, ultimately leading to liver failure, necessitating liver transplant as the only treatment option in advanced stages. Early diagnosis and management of underlying causes are crucial in preventing further damage and complications.
