von Willebrand disease (vWD) is a common genetic blood disorder that impairs blood clotting leading to excess bleeding. In people with vWD, a protein called von Willebrand factor that is critical to blood clotting either does not function properly or is insufficient. As a result, people with vWD bleed more easily.
Your doctor may ask these questions to check for this disease:
While there is no cure, it can be managed and people can live normal lives. Mild cases of vWD may only have to be treated if injured or before surgical procedures where bleeding might be expected. Medications or injection of clotting factors may be prescribed to help the blood clot in more severe cases.

Q.
Scared of Brilinta? Why Your Blood Is Not Clotting & Medically Approved Next Steps
A.
If you are on Brilinta and notice your blood is not clotting, that is often the medication working as intended to prevent heart attacks and strokes, with mild bruising or longer bleeding being common, but red flag bleeding needs urgent care and you should never stop the drug without your doctor’s guidance. There are several factors to consider, including other medicines like aspirin, possible bleeding disorders such as vWD, and practical, medically approved next steps to reduce risk and decide when to seek help; see the complete answer below.

Q.
Unexplained Bleeding? Von Willebrand Disease: Why Your Blood Won’t Clot & Next Steps
A.
Unexplained bleeding can be caused by von Willebrand disease, the most common inherited bleeding disorder, where a low amount or poor function of von Willebrand factor slows clotting and leads to easy bruising, frequent nosebleeds, and heavy menstrual bleeding. There are several factors to consider, including acquired forms, the need for specialized and sometimes repeat blood tests, and treatments like desmopressin, von Willebrand factor concentrates, antifibrinolytics, and menstrual management, plus when to seek emergency care and how to plan for surgeries and dental work; see below for the complete guidance on next steps to discuss with your doctor.
