What are the symptoms of von Willebrand disease?
Von Willebrand disease can be a mild disorder and often children have very few symptoms. Recurrent nosebleeds are a common complaint in children with vWD. Usually, children with vWD bruise easily, or bleed after tooth extraction, tonsillectomy or other surgery. Females can have increased menstrual bleeding. A person's symptoms may change throughout their life, but the type of vWD does not change.
How is von Willebrand disease diagnosed?
Von Willebrand disease can be difficult to diagnose. This is partly because the results of a person's blood tests can vary day-to-day. For example, the amount of von Willebrand factor can be temporarily increased when a child/teen:
Is under stress.
Has an infection.
Has recently undergone surgery.
Has recently undergone a blood transfusion.
