Types of VWD

There are three main types of von Willebrand disorder:

  • Type 1 VWD is the most common.  In type 1 VWD, the von Willebrand Factor (VWF) works normally, but there is not enough of it. Symptoms are usually mild, depending on the level of VWF in the blood
  • In type 2 VWD, the amount of VWF in people’s blood is often normal but the VWF doesn’t work properly. There are many different ways that this can happen. Depending on the type of problem with the VWF it will be called VWD type 2A, 2B, 2M, or 2N. For these subtypes your haematologist will be able to provide you with specific information, as  you may need different treatment
  • Type 3 VWD is very rare. People with type 3 VWD have very little or no VWF in their blood. Symptoms are more severe and can also include joint and muscle bleeding. Bleeding can occur more often.
