About Von willebrands factor

What is von Willebrand factor?

Von Willebrand factor is a component of blood that helps to form clots during bleeding. Some individuals have a genetic condition which results in low levels of von Willebrand factor in their blood, reducing the speed of clotting in response to damage. This disease is called von Willebrand disease (VWD), there is no cure for the disorder but sufferers can typically live normal lives with medication and lifestyle adjustment. Symptoms of VWD include; bruising easily, frequent nosebleeds, bleeding from gums, excessive bleeding from cuts and generally increased times for bleeding to stop. In women, it can affect periods and bleeding during childbirth.
