Hemophilia is a disorder of your blood-clotting system. Clotting is the process by which your blood changes from a liquid to a solid state.

There are several types of hemophilia. All types can cause prolonged bleeding. If you have hemophilia and you have a cut, you'll bleed for a longer time than you would if your blood clotted normally. Small cuts usually aren't much of a problem. The greater health concern, particularly with hemophilia A and B, is deep internal bleeding and bleeding into joints.

Hemophilia is a lifelong disease, but with proper treatment and self-care, most people with hemophilia can maintain an active, productive lifestyle.
