Hemophilia (heem-o-FILL-ee-ah) is a rare, inherited bleeding disorder in which your blood doesn't clot normally. If you have hemophilia, you may bleed for a longer time than others after an injury. You also may bleed internally, especially in your knees, ankles, and elbows. This bleeding can damage your organs or tissues and, sometimes, be fatal.
There are two main types of hemophilia. If you have hemophilia A, you have little to no clotting factor VIII (8). About 9 out of 10 people with hemophilia have type A. If you have hemophilia B, you're missing or have low levels of clotting factor IX (9).
