March 7th Fact: Von Willebrand Disease (vWD) is the most common #bleedingdisorder (1-2% of the world’s population), and affects males and females equally.

Many people with vWD are under or misdiagnosed because of mild symptoms. Those with vWD have lower or malfunctioning von Willebrand Factor activity, and thus cannot form a proper platelet plug.

Depending on the type and severity of the condition, someone with vWD can experience mild, moderate, or severe bleeding episodes. The types of vWD include: Type 1, Type 2a, Type 2b, Type 2m, Type 2n, and Type 3. Symptoms may include: nose bleeds, prolonged bleeding from cuts, heavy menstrual bleeding, blood in the urine/stool, unexplained bruises, bleeding gums. Unlike #hemophilia, vWD can have different inheritance patterns. Most cases of Type 1 and Type 2 are inherited in an autosomal dominant pattern. Type 3 are inherited in an autosomal recessive pattern. Learn more:
