In liver disease, especially cirrhosis, there is a decrease in hepatic synthesis of clotting factors, particularly factor II (prothrombin). Vitamin K deficiency is also common in liver disease, which further contributes to hypoprothrombinemia. The deficiency of fibrinogen (factor I) would also result in a bleeding diathesis but is less common in liver disease. Factors V and VIII are also synthesized in the liver but are less frequently affected than factor II in such cases.
