Von Willebrand Disease Directory

Von Willebrand disease is a genetic bleeding disorder that results from lack of a certain protein in the blood. There are three types: type 1, the most common type, where you are missing some of the von Willebrand factor; type 2, in which the factor does not work correctly; and type 3, the most severe deficiency. Symptoms of von Willebrand disease are nosebleeds, gum bleeding, heavy periods, frequent bruising, and taking a long time for blood to clot. Follow the links below to find WebMD's comprehensive coverage about how von Willebrand disease is caused, how to treat it, and much more.
