Hemophilia A

Also known as: classic hemophilia, factor VIII deficiency, FVIII deficiency, clotting factor deficiency.

What is hemophilia A?

Hemophilia is a disease in which the blood is missing a component that makes it clot properly. The result is that the individual with hemophilia can bleed easily, bleed excessively or not stop bleeding once they start. In the case of hemophilia A, or classic hemophilia, the blood is deficient in factor VIII.

What causes hemophilia A?

Most people inherit hemophilia A from their mothers. In some children, though, the disease is not inherited and develops through a genetic mutation.

What are the symptoms of hemophilia A?

The primary symptoms of hemophilia A include easy bruising, excessive bleeding, or the inability to stop bleeding after an injury. Other symptoms include blood in the urine or stools, joint pain and swelling.

What are hemophilia A care options?

Comprehensive care at a Hemophilia treatment center is the standard of care for individuals with Hemophilia A. A hematologist will likely prescribe factor replacement products depending on the individual’s severity. Patients with Hemophilia A can enjoy an active lifestyle with the guidance of a hematologist.
