The medical condition hemophilia is a bleeding disorder where your blood does not clot normally because your blood lacks sufficient blood-clotting proteins called clotting factors. People who have hemophilia contain low levels of clotting factor VIII (8) or factor IX (9) in their blood. This amount of clotting factor varies from patient to patient with hemophilia and determines the severity of the disorder. Hemophilia occurs in mostly men and the two main types of hemophilia are Hemophilia A and Hemophilia B.
