Bleeding Episodes

Abstract

The effects of these disorders are very similar and they will be discussed together. They are related to the level of factor VIII in the blood in the case of haemophilia A, and of factor IX in haemophilia B. They are also related to the individual; some haemophiliacs with very low factor levels rarely experience trouble, whilst others with the same level have many bleeds. If there is a family history of the disorder it is usually found that different members of the family are affected to the same extent both in terms of factor level and in terms of frequency of bleeding. Some haemophiliacs recognize phasic or seasonal bleeding, and some seem to bleed more when they are tense and anxious.
