Hemophilia is primarily an inherited disease that does not allow blood to clot properly. There is a deficiency in the body of the necessary proteins also called clotting factors needed to stop bleeding. Hemophilia A is the deficiency of clotting factor VIII and affects about 1 in 10,000 males. Hemophilia B is the deficiency of clotting factor IX and affects about 1 in 60,000 males.
Von Willebrands is also an inherited disease that does not allow blood to clot properly. The missing factor with this disorder is von Willebrand factor and affects 1%-2% of the population. It occurs equally in both males and females.
