Overview, Causes, & Risk Factors
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.
