Von Willebrand Disease
Moderate
Von Willebrand disease is an inherited bleeding disorder caused by reduced amounts or abnormal function of von Willebrand factor, a protein that helps blood clot properly. People with the condition may bruise easily or experience prolonged nosebleeds, bleeding after injuries, or excessive bleeding after surgery or dental procedures. Menstrual bleeding may also be unusually heavy or prolonged. Severity varies considerably among the different types of the disorder.

When to Seek Medical Attention
Von Willebrand disease should be medically assessed when abnormal or recurrent bleeding occurs. Seek prompt care for prolonged bleeding after injuries or procedures, frequent significant nosebleeds, unusually heavy menstrual bleeding, or unexplained bruising. Emergency assessment is needed for uncontrolled bleeding, signs of significant blood loss, severe weakness or fainting, blood in vomit or stool, or bleeding that cannot be stopped.

Overview
Von Willebrand disease is an inherited bleeding disorder caused by reduced amounts or abnormal function of von Willebrand factor, a protein that helps blood clot properly. People with the condition may bruise easily or experience prolonged nosebleeds, bleeding after injuries, or excessive bleeding after surgery or dental procedures. Menstrual bleeding may also be unusually heavy or prolonged. Severity varies considerably among the different types of the disorder.

Nosebleed
Causes 2
Von Willebrand disease is usually caused by inherited variants affecting the VWF gene, which provides instructions for making von Willebrand factor. This protein helps platelets attach to damaged blood vessels and supports normal clot formation. Type 1 generally involves reduced amounts of the factor, while type 2 involves impaired function. Type 3 causes a severe deficiency. A rare acquired form can develop later in life in association with other disorders.
Autoimmune Disorder
Genetics
Risk Factors
A family history of von Willebrand disease or another inherited bleeding disorder is an important risk factor. The condition can be inherited in different patterns depending on the specific type. People with affected relatives may therefore have an increased likelihood of carrying a disease-causing genetic variant. Symptoms can vary even among family members, so a person with a relatively mild bleeding history may still have the condition.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis can be challenging because von Willebrand factor levels and bleeding symptoms can vary over time. Evaluation usually includes a personal and family bleeding history together with blood tests. Testing may measure von Willebrand factor amount and activity, factor VIII levels, platelet function, and related clotting measures. Repeated or specialized testing may sometimes be necessary to distinguish von Willebrand disease from other causes of abnormal bleeding.
Prevention
Key Prevention Tips
Inherited von Willebrand disease cannot currently be prevented because it results from genetic changes passed through families
People with a family history can discuss genetic counseling and appropriate testing with healthcare professionals
Individuals who have been diagnosed should inform healthcare providers before surgery, dental procedures, or other invasive procedures so bleeding risk can be considered
Recognizing abnormal bleeding early can help reduce complications and improve planning for medical care
Prevention Guidance
Inherited von Willebrand disease cannot currently be prevented because it results from genetic changes passed through families. People with a family history can discuss genetic counseling and appropriate testing with healthcare professionals. Individuals who have been diagnosed should inform healthcare providers before surgery, dental procedures, or other invasive procedures so bleeding risk can be considered. Recognizing abnormal bleeding early can help reduce complications and improve planning for medical care.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
