Types Of Hemophilia

A person has nine clotting factor proteins in the blood to help their body stop bleeding and are numbered using roman numerals. Patients with Hemophilia are missing one of these factors. There are three main types of Hemophilia: A, B, and C. A milder, yet prominent disease similar to Hemophilia is called Von Willebrand disease.

• Hemophilia A: Caused by a deficiency of clotting factor VIII; most common Hemophilia as about 85% of patients have type A.

• Hemophilia B: Caused by a deficiency of clotting factor IX.

• Hemophilia C: Caused by a deficiency of clotting factor XI

• Von Willebrand disease: A Hemophilia-like bleeding disorder where a part of the factor VIII is diminished. Von Willebrand disease is similar to hemophilia, but does not have the same name as it is more common, usually does not cause bleeding in the joints, and is normally milder than hemophilia.
