What it means
Hemophilia is a rare genetic bleeding disorder in which the blood does not clot properly because it is missing or has low levels of certain clotting factors (factor VIII in hemophilia A, factor IX in hemophilia B). It affects mostly males. People with hemophilia can bleed for longer than usual after injury, and may experience spontaneous internal bleeding, especially into joints and muscles. Severity ranges from mild to severe. Treatment involves replacing the missing clotting factor through intravenous infusions, either on a preventive schedule or when bleeding occurs. Newer treatments include extended half-life factor products and non-factor therapies.
