Hemophilia is a bleeding disorder in which there is a deficiency of selected proteins in the body’s blood-clotting system. “Clotting is the process by which your blood changes from a liquid to a solid state in order to stop bleeding”. There are three main types of hemophilia in which a different clotting factor is missing or deficient. In the most common type, Hemophilia A, clotting Factor VIII is missing or deficient. In Hemophilia B, Factor IX is missing or deficient, and in Hemophilia C, Factor XI is missing or deficient. All three types can cause prolonged bleeding.
