About Hemophilia

About Hemophilia and Bleeding Disorders

Bleeding disorders are a group of inherited disorders. Continued improvement in outcomes depends on the provision of this care by a multidisciplinary team comprised of physicians who:

  • Understand the nature of the underlying condition.
  • Can closely follow patients.
  • Screen and monitor for complications.
  • Prevent complications as far as possible.
  • Address other concerns including transition to adult providers and psychosocial counseling.

In some people, the clotting process does not work properly and it may be difficult or take longer to stop bleeding.


Hemophilia is a bleeding problem. It is usually hereditary and most often occurs in males. With this condition, clotting factors VIII or IX are missing or defective in forming a blood clot. This means that people with hemophilia are at risk for bleeding easier and for a longer period of time than other people. Depending on the level of factor hemophilia can be mild, moderate or severe. 

Von Willebrand Disease 

Von Willebrand Disease ( VWD) is the most common type of inherited bleeding disorder. People with this bleeding problem, both males and females, have less Von Willebrand Factor or it does not work to help form a blood clot in the way it should. 

Rare Coagulation Deficiencies

Rare Coagulation Deficiencies are inherited bleeding disorders that are uncommon. People with rare bleeding disorders are often missing a clotting factor that help to form a blood clot and prevent bleeding symptoms.
