Question 2

What is von Willebrand disease in humans?

Accepted Answer

Von Willebrand disease is a genetic bleeding disorder caused by a deficiency or dysfunction of von Willebrand factor, a protein that helps blood clot. This can lead to easy bruising, frequent nosebleeds, and prolonged bleeding after injuries or surgery.

Question 3

How is von Willebrand disease inherited?

Accepted Answer

VWD is usually inherited in an autosomal dominant pattern, which means a child can inherit the disorder if just one parent carries the gene. Both males and females can be affected.

Question 4

How is von Willebrand disease diagnosed?

Accepted Answer

Diagnosis involves blood tests that measure von Willebrand factor levels and activity, as well as other clotting tests. Diagnosis may require specialized laboratory testing and evaluation by a hematologist.

Question 5

How does von Willebrand disease affect the body?

Accepted Answer

People with VWD may experience frequent nosebleeds, easy bruising, heavy menstrual periods, and prolonged bleeding from cuts or dental work. In severe cases, internal bleeding into joints or muscles can occur.

Question 6

How is von Willebrand disease different from hemophilia?

Accepted Answer

While both are bleeding disorders, von Willebrand disease is caused by problems with von Willebrand factor, while hemophilia is caused by deficiencies in clotting factor VIII or IX. VWD affects both men and women, while classic hemophilia mostly affects males.

Question 7

Can von Willebrand disease get worse?

Accepted Answer

Symptoms can vary over time and may worsen with certain triggers, such as surgery, injury, or hormonal changes. However, many people with mild VWD may have few symptoms most of the time.

Question 8

Can von Willebrand disease be cured?

Accepted Answer

There is no cure for von Willebrand disease, but it can be managed with medication and careful planning around surgeries, dental work, or injuries. Most people with VWD live healthy lives with proper care.

Question 9

Can von Willebrand disease cause anemia or fatigue?

Accepted Answer

Yes, people with VWD who experience frequent or heavy bleeding, especially from the gastrointestinal tract or during menstruation, may develop anemia and symptoms like fatigue.

Question 10

Can von Willebrand disease cause miscarriage?

Accepted Answer

Von Willebrand disease may increase the risk of bleeding complications during pregnancy, labor, and delivery. While most women with VWD can have healthy pregnancies, they should be closely monitored by their healthcare team to reduce risks.
