In severe cases of haemophilia, continuous bleeding occurs after
minor trauma or even in the absence of injury (known as spontaneous
bleeding). Serious complications can result from bleeding into the
joints, muscles, brain, or other internal organs. This can lead to
chronic pain and limited mobility.
Medication is given as injections, either when a bleed occurs (on
demand therapy), or on a regular basis to prevent bleeds from
occurring in the first place.
Many people with haemophilia are still undiagnosed or inadequately treated.
