Introduction
Von Willebrand disease (VWD) is the most common inherited bleeding disorder, caused by deficient or dysfunctional von Willebrand factor (VWF) needed for platelet adhesion and carrying factor VIII.
Symptoms include easy bruising, prolonged nosebleeds, heavy menstrual bleeding, and excessive bleeding after dental work or surgery. Severity varies widely.
Diagnosis uses bleeding history, VWF antigen and activity assays, and factor VIII level. Treatment includes desmopressin, VWF concentrates, and antifibrinolytics.
This page explains common symptoms, how evaluation usually proceeds, treatment options, and when to seek medical care.
Overview
Type 1 is partial quantitative deficiency most common; type 2 qualitative variants; type 3 severe absence with major bleeding.
Acquired VWD can occur with lymphoproliferative or autoimmune disorders.
- Most common inherited bleeding disorder
- Easy bruising and mucosal bleeding typical
- Heavy periods common in women
- VWF and factor VIII testing diagnoses
- Desmopressin helps many type 1 patients
- Plan hemostasis before procedures
What happens in the body
Low or abnormal VWF fails to bind platelets to damaged endothelium and stabilizes factor VIII poorly, shortening its half-life and impairing clot formation at mucosal sites.
Platelet plug formation is delayed causing soft tissue and mucosal bleeding rather than deep joint bleeds typical of hemophilia A.
- Reduced VWF decreases platelet adhesion
- Factor VIII may be low secondarily
- Mucosal capillary bleeding predominates
- Stress and pregnancy can temporarily raise VWF
Signs and symptoms
Common symptoms and warning signs may include:
- Frequent nosebleeds
- Easy bruising with large ecchymoses
- Heavy or prolonged menstrual periods
- Excessive bleeding after tooth extraction
- Prolonged bleeding from cuts
- Postpartum hemorrhage risk
- GI bleeding in severe types
Causes and risk factors
Possible causes and contributing factors include:
- Inherited VWF gene mutations types 1 to 3
- Autosomal pattern usually milder in heterozygotes
- Acquired autoantibodies to VWF in malignancy or autoimmune disease
- Aortic stenosis associated acquired form rare
- Family history of bleeding symptoms
Diagnosis and evaluation
Evaluation may include:
- Bleeding assessment tool score
- VWF antigen, activity (ristocetin cofactor), factor VIII
- Repeat testing because VWF is acute phase reactant
- Platelet function tests and multimer analysis for type 2
- Exclude other coagulopathies
- Genetic testing in complex cases
Treatment and management
Treatment and management may involve:
- Desmopressin trial in responsive type 1 before procedures
- VWF/factor VIII concentrate for surgery or severe bleeding
- Tranexamic acid for mucosal bleeding and menses
- Hormonal contraception reducing menstrual flow
- Topical hemostatic agents in dental care
- Avoid NSAIDs and antiplatelet agents when possible
- Pregnancy monitoring as VWF rises then falls postpartum
- Hematology plan for all surgeries and deliveries
Prevention, self-care, and lifestyle
Not every condition is fully preventable, but the steps below may lower risk or recurrence:
- Preprocedure hemostatic planning once diagnosed
- Genetic counseling for family screening
- Medical alert identification for severe types
Possible complications
Delay, missed care, or unsafe self-medication can raise the chance of complications in some cases:
- Iron deficiency anemia from chronic bleeding
- Life-threatening hemorrhage with surgery if unprepared
- Postpartum hemorrhage
- Joint or soft tissue bleeds in severe type 3
- Delayed diagnosis leading to unnecessary procedures without cover
When to see a doctor or seek emergency care
Seek prompt medical advice or emergency care if any of the following apply—it is safer not to wait and see:
- Heavy menstrual bleeding or frequent nosebleeds
- Family bleeding disorder with your symptoms
- Planned surgery or dental extraction needing hemostasis plan
- Bleeding not responding to usual measures
Living with the condition
Carry a treatment letter from hematology listing diagnosis and effective therapies. Inform dentists and surgeons well before appointments. Track menstrual blood loss and treat iron deficiency if it develops.
Frequently asked questions
Is von Willebrand disease hemophilia?
No. It is a distinct disorder affecting VWF and often platelet function at mucosal sites. Hemophilia A is factor VIII deficiency with deeper joint bleeding tendency.
Can women with VWD have children?
Yes, with hematology and obstetric planning. VWF often rises in pregnancy but drops after delivery when bleeding risk peaks.
