Introduction

Von Willebrand disease is the most common inherited bleeding disorder.

People withVon Willebrand disease (VWD) either have a deficiency of a blood protein called Von Willebrand factor, or this protein doesn't work properly.This means that their blood cannot clot properly and they are prone to prolonged or excessive bleeding.

Von Willebrand factor acts like a glue which allows platelets (a type of blood cell) to stick together and to plug up damaged blood vessels. It also carries and protects another clotting factor called FVIII (factor 8).
