The differences between haemophilia A and B are in the factor that is missing or at a low level  haemophilia A means low levels of factor VIII (8) and haemophilia B is low levels of factor IX (9). This means that the treatment given to replace the factor is different  haemophilia A needs to be treated with factor VIII and haemophilia B with factor IX replacement. Giving factor VIII to someone with haemophilia B wont help to stop the bleeding.



Haemophilia A and B are both bleeding disorders that are congenital (passed on at birth through the genes), and are caused by a low level or absence in one of the factors normally found in the blood that help make a stable blood clot. A poor blood clot will mean that a person is at risk of bleeding internally, and most often inside the joints or muscles. This can happen when moving normally or exercising or straining, or due to an injury, and a clot will take longer to form and stop the bleeding. The person is also at risk of re-bleeding when the poor blood clot that is formed breaks down too soon.



All the best!

Haemophilia -

Bleeding disease that occurs almost exclusively in males.

It is an X linked recessive disorder.

Haemophilia A -

It is caused due to lack of synthesis of AHG (Anti haemophilic Globulin)/Anti haemophilic Factor A/ Factor VIII.



As AHG is not synthesized, small cuts can lead to continuous bleeding for long time.

Haemophilia B -

It is caused due to lack of synthesis of Christmas Factor/Anti haemophilic Factor B/Factor IX.



Haemophilia B is also called Christmas disease.

There is another type of Haemophilia, called Haemophilia C which is caused due to lack of synthesis of PTA (Plasma Thromboplastin Antecedent)/Anti haemophilic Factor C/Factor XI.

Hi Ram Mohan Nayak !

The differences between haemophilia A and B are in the factor that is missing or at a low level – haemophilia A means low levels of factor VIII (8) and haemophilia B is low levels of factor IX (9). This means that the treatment given to replace the factor is different – haemophilia A needs to be treated with factor VIII and haemophilia B with factor IX replacement. Giving factor VIII to someone with haemophilia B won’t help to stop the bleeding.

Haemophilia A and B are both bleeding disorders that are congenital (passed on at birth through the genes), and are caused by a low level or absence in one of the ‘factors’ normally found in the blood that help make a stable blood clot. A poor blood clot will mean that a person is at risk of bleeding internally, and most often inside the joints or muscles. This can happen when moving normally or exercising or straining, or due to an injury, and a clot will take longer to form and stop the bleeding.  The person is also at risk of re-bleeding when the poor blood clot that is formed breaks down too soon.

People with zero levels of factor are described as having severe haemophilia, and these people are at most risk of bleeding. People with higher levels up to the normal ranges are described as having moderate or mild haemophilia, and the risk of bleeding is less for someone with mild haemophilia.
