Haemophilia
Haemophilia is a hereditary bleeding disorder that affects people from birth. The blood of a person with haemophilia does not clot normally because they lack one or more of the plasma proteins needed to form a clot and stop bleeding. There are 13 main clotting factors (identified by roman numerals) that work together to produce a clot. If one factor is missing the chain reaction is broken, clots will not form properly, and bleeding will continue.
