Overview 

Von Willebrand Disease is a common inherited bleeding disorder caused by a deficiency or dysfunction of von Willebrand factor (VWF), a protein essential for blood clotting.

This condition leads to prolonged bleeding after injury, surgery, or dental procedures. It can affect both men and women and may vary from mild to severe. Early diagnosis and proper management help prevent complications.

Types of Von Willebrand Disease

• Type 1: Mild deficiency of VWF (most common)
• Type 2: Abnormal function of VWF
• Type 3: Severe deficiency or absence of VWF

Acquired Von Willebrand Disease - Develops later due to other medical conditions

Symptoms of Von Willebrand Disease

• Frequent nosebleeds
• Easy bruising
• Prolonged bleeding from cuts
• Heavy menstrual bleeding in women
• Bleeding after surgery or dental procedures
• Blood in urine or stool (in severe cases)

Causes of Von Willebrand Disease

• Genetic mutation affecting VWF production
• Inherited from one or both parents
• Associated with other medical conditions (acquired form)
• Exact mechanism varies by type

Complications of Von Willebrand Disease

• Severe bleeding episodes
• Anemia due to blood loss
• Joint or muscle bleeding (in severe cases)
• Complications during surgery or childbirth
• Reduced quality of life

Risk Factors of Von Willebrand Disease

• Family history of bleeding disorders
• Genetic predisposition
• Certain underlying medical conditions (for acquired type)

Prevention of Von Willebrand Disease

• Genetic counseling for families
• Avoiding medications that increase bleeding (e.g., aspirin)
• Preventive care before surgeries
• Regular medical monitoring
