What is (are) Von Willebrand disease ?
Von Willebrand disease is a bleeding disorder that slows the blood clotting process. People with this disease often experience bruising, nosebleeds, and prolonged bleeding or oozing following an injury, surgery, or having a tooth pulled. In severe cases, heavy bleeding occurs after minor injury or even in the absence of injury. Milder forms of Von Willebrand disease do not involve spontaneous bleeding, and the disease may become apparent only when abnormal bleeding occurs following surgery or a serious injury. Symptoms may change over time. Increased age, pregnancy, exercise, and stress may make bleeding symptoms may become less frequent. This disease is caused by mutations in the VWF gene and can have different inheritance patterns.
