Other Bleeding Disorders

Apart from haemophilia and von Willebrand disease, there are also other rare inherited bleeding disorders.

Rare clotting factor deficiencies are caused when a particular factor or protein in the blood that helps blood to clot is lower than normal, missing or doesn’t work properly.

In inherited platelet function disorders, the platelet plug does not form properly, leading to a tendency to bleed for longer than normal or bruise easily. Since platelets have many roles in blood clotting, platelet function disorders can range from mild to severe. Examples include Glanzmann thrombasthenia and Bernard-Soulier syndrome.
