Haemophilia is a rare disorder in which blood doesn’t clot in the typical way because it doesn’t have enough blood-clotting proteins (clotting factors).7
The two most common types of haemophilia are A and B.7
Haemophilia A is the most common type of haemophilia and is caused by a lack of blood clotting factor VIII (FVIII), whereas haemophilia B is caused by a lack of factor IX (FIX).7
The more severe the condition, the less able a person is to form blood clots, making them more vulnerable to bleeding.5
