How common is Von Willebrand's dieaese?

Von Willebrand's disease is the most common hereditary bleeding disorder. It affects both sexes approximately equally. Most cases are mild, and bleeding may occur after a surgical procedure or tooth extraction. The condition is worsened by the use of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs). Bleeding may decrease during pregnancy.

The disease is very common, affecting at least 1% of the population. There are no racial or ethnic associations with this disorder. A family history of a bleeding disorder is the primary risk factor.

Symptoms include nose bleeds, bleeding of the gums, abnormal menstrual bleeding, bruising, and skin rash.
