Von Willebrand Disease

Von Willebrand Disease (VWD) is the most common hereditary blood clotting disorder that occurs in up to 2% of the population. It affects men and women equally and is considered to generally be a mild condition. Individuals with VWD either do not produce enough of one of the many proteins needed to produce a clot, von Willebrand factor, or the von Willebrand factor does not function properly.
