Hemophilia is a genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding. This disorder is caused by the deficiency of specific clotting factors, such as factor VIII (hemophilia A) or factor IX (hemophilia B). People with hemophilia may bleed for a longer time after an injury, and they may experience spontaneous internal bleeding, especially in the joints and muscles. Hemophilia is typically inherited in an X-linked recessive pattern, affecting mostly males.Treatment involves replacing the missing clotting factors.
