Acquired haemophilia

Nearly all people with haemophilia are born with it. This is called a hereditary bleeding disorder. However, a person can develop a different kind of haemophilia throughout life, usually as an adult, although this is very rare. This is known as an acquired bleeding disorder. 

Acquired haemophilia can occur when a person’s immune system produces antibodies that mistakenly target their own factor VIII. It is very rare but can sometimes occur in older people and young women who are in the later stages of pregnancy or have recently given birth. The bleeding pattern is different to inherited haemophilia and it is usually curable with treatment.

Acquired bleeding disorders are not inherited or passed on to children. Men and women are equally likely to be affected by an acquired bleeding disorder.
