What is von willebrand's disease ?

VWD is a mild form: Of factor viii function defect which increases bleeding risk. Much less serious than hemophilia.

A bleeding problem: Platelets stop bleeding by patching holes in blood vessels. von Willebrand factor is the glue that sticks platelets to those holes. If von Willebrand factor is low, or if the structure of VWF is abnormal, it doesn't stick platelets to the sites of bleeding. Most people have nosebleeds, gum bleeding, or bleeding after tooth extraction. There are 4 types of VW disease with different symptoms.
