Definition
By Mayo Clinic staffHemophilia is a disorder of your blood-clotting system. Clotting is the process by which your blood changes from a liquid to a solid state in order to stop bleeding.
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 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.
