Document Summary
Cirrhosis: cirrhosis a chronic, progressive and degenerative disease, characterized by replacement of normal liver tissue with diffuse fibrosis that disrupts the structure and function of the liver, men are more commonly affected than women. It is irreversible: there are 3 types of cirrhosis or scarring of the liver, alcoholic scar tissue characteristically surrounds the portal areas. This is most frequently caused by chronic alcoholism and is the most common type of cirrhosis: postnecrotic cirrhosis in which there are broad bands of scar tissue. This is a late result of a previous bout of acute viral hepatitis: biliary cirrhosis in which scarring occurs in the liver around the bile ducts. This type of cirrhosis usually results from chronic biliary obstruction and infection (cholangitis); least common type. Risk factors: alcohol ingestion, viral or autoimmune hepatitis, fatty liver disease, bile duct obstruction, toxic hepatitis, inherited diseases, hepatic congestion, constrictive pericarditis/ valvular disease. Worsened by poor nutritional status (inadequate protein intake)
