Understanding Von Willebrand Disease and Bleeding Disorders

A bleeding disorder means the body struggles to stop bleeding after an injury. While some are rare, others, like von Willebrand disease (VWD), are surprisingly common. This condition, also known as angiohemophilia, often begins with mild symptoms that can easily go unnoticed. However, if left undetected for a long time, even mild symptoms can pose a risk. Many people only recognise its seriousness once it progresses and leads to more significant health complications.

Understanding how this condition affects the body is important. Recognising the early signs can help individuals seek timely diagnosis and treatment. This, in turn, allows patients to manage the condition effectively. This blog explains what von Willebrand disease is, its symptoms, causes, and treatment options. 

What is Von Willebrand Disease?

Von Willebrand disease is a bleeding disorder that occurs when the body lacks enough of a protein called von Willebrand factor (VWF) or when this protein does not work properly. VWF plays a key role in helping the blood clot. When a person gets injured, it helps platelets stick to the damaged blood vessels and form a clot to stop the bleeding. However, in individuals with this condition, this process does not work as it should. As a result, even minor cuts or injuries can lead to prolonged or excessive bleeding. 

It is to be noted that this condition is usually inherited and affects both sexes. However, women may experience more severe symptoms due to menstruation and childbirth. This VWD is a lifelong condition, and constant monitoring is recommended to avoid any life-threatening situations.  

Common Symptoms of Von Willebrand Disease

The symptoms of this disease can vary from one person to another. Those trying to understand the disorder should watch for the following common signs and symptoms:

1. Frequent Nosebleeds

Individuals with this condition may experience nosebleeds more often than usual, and these episodes can last longer than expected. The bleeding may occur without a clear trigger, such as injury or dryness, and can sometimes be difficult to stop. In some cases, repeated nosebleeds may interfere with daily activities or cause discomfort. This makes even minor nosebleeding episodes more persistent and noticeable.

2. Easy Bruising

People with this condition may bruise easily, even after minor bumps or slight pressure on the skin. These bruises can appear larger and darker than usual and may take a longer time to heal. This occurs due to impaired blood clotting, which allows blood to leak under the skin more easily, resulting in visible discolouration and tenderness.

3. Prolonged Bleeding from Cuts

Even small cuts or injuries can lead to prolonged bleeding in individuals with this condition. Unlike a normal situation, where bleeding stops within a short time, these individuals may continue to bleed. This can make minor injuries more concerning and may require extra care to manage.

4. Bleeding after Dental Procedures or Surgery

People with von Willebrand disease may experience excessive or prolonged bleeding during and after dental treatments or surgical procedures. Even routine procedures, such as tooth extractions or minor surgeries, can lead to significant blood loss. This can complicate the treatment process and may require special precautions or medications to control bleeding. Healthcare providers often need to plan carefully to minimise risks and ensure the patient’s safety during such procedures.

5. Heavy Menstrual Bleeding

Women with this condition may experience heavy or prolonged menstrual bleeding, which can be one of the most noticeable symptoms. Periods may last longer than usual and involve a higher volume of blood loss. This can lead to fatigue, discomfort, and, in some cases, iron deficiency or anaemia. Managing menstrual health becomes important, as untreated heavy bleeding can affect overall well-being and daily functioning over time.

6. Bleeding from the Gums

Bleeding from the gums is another common symptom, especially during routine activities such as brushing or flossing. Individuals may notice that their gums bleed more easily and for a longer duration than expected. This can occur even without underlying dental issues.

7. Other Symptoms

In more severe cases, individuals may experience bleeding in deeper tissues, such as the joints and muscles, or even internal organs. This type of bleeding may not always be immediately visible but can cause pain, swelling, and restricted movement. Internal bleeding can be serious and may require urgent medical attention. These complications highlight the importance of proper diagnosis and ongoing management of the condition.

Causes of Von Willebrand

This disease is primarily caused by genetic changes that affect blood clotting, although certain factors may increase the likelihood of developing or worsening the condition.

• Genetic Mutation: The condition is mainly caused by a mutation in the gene responsible for producing VWF, a protein essential for blood clotting.
• Inherited Condition: In most cases, it is passed down in an autosomal dominant pattern, meaning a child can develop the condition by inheriting the mutated gene from one parent.
• Severe Inherited Forms: Some severe types follow different inheritance patterns and may require mutations from both parents.
• Family History: Having a close family member with the condition increases the risk of developing it.
• Associated Medical Conditions: In some cases, the disorder may be acquired later in life due to immune disorders or certain heart conditions.
• Blood Type: Individuals with blood type O may naturally have lower levels of VWF, which can be linked to increased bleeding tendencies.

Diagnosis of Von Willebrand Disease

Diagnosing this disease involves evaluating a person’s medical history along with specific tests to assess how well the blood clots.

• Medical and Bleeding History: The doctor reviews past bleeding episodes and checks for signs such as frequent bruising or recent bleeding.
• VWF Antigen Test: This measures the amount of VWF present in the blood.
• VWF Activity Test: This assesses how effectively VWF functions in the clotting process.
• Factor VIII Activity Test: This determines whether the levels and function of factor VIII, another clotting protein, are within a normal range.
• VWF Multimer Analysis: This examines the structure and size of VWF to help identify the specific type of the disorder.
• Repeat Testing: Since test results may vary due to factors like stress, illness, or medications, some tests may need to be repeated for accuracy.
• Specialist Referral: Patients may be referred to a haematologist for further evaluation and confirmation of the diagnosis.
• Family Screening: Close relatives may also be advised to undergo testing to check if the condition is inherited.

Treatment Options for Von Willebrand Disease

While there is no cure for this disease, there are different treatment options available to control it and effectively manage symptoms. They are as follows:

1. Medications

There are multiple types of medication which doctors can prescribe to patients. These can help to stimulate the release of VWF stored in the body. There are also other medicines which can help stabilise blood clots and reduce bleeding during medical procedures.

2. Replacement Therapy

In cases of this disease, replacement therapy is recommended by doctors. This is done by infusing VWF into the blood. Replacement therapy is recommended when a person needs to undergo surgery or dental procedures.

3. Hormonal Treatments

Women who face abnormally heavy periods can feel better by taking hormonal treatments. These could be oral contraceptives or other treatments as suggested by doctors. Such a treatment can help monitor and keep control of menstrual cycles. It also reduces blood loss. 

4. Antifibrinolytic Medications

Such medications are used to help stabilise blood clots after they have formed, preventing them from breaking down too quickly. These medicines work by blocking the natural process that breaks down clots, allowing the body more time to heal. They are commonly prescribed during dental procedures, minor surgeries, or injuries, where there is a higher risk of continued bleeding.

5. Lifestyle Precautions

Those living with this disease may feel better when they make certain lifestyle changes or adjustments. By avoiding medication that can increase bleeding risk, one can prevent other health complications. Another thing one must do is inform their healthcare professionals about this condition before any surgery.

Conclusion

Bleeding disorders often go unnoticed until a serious injury, surgery, or unexpected bleeding episode occurs. Von Willebrand disease, despite being the most common inherited bleeding disorder, is frequently underdiagnosed in its early stages. Without timely attention, it can lead to prolonged bleeding, complications, and a reduced quality of life. Recognising the symptoms and seeking early diagnosis is essential. However, repeated tests, consultations, and ongoing care can become costly, placing a financial strain on families over time.

For Non-Resident Indians (NRIs), ensuring that their loved ones in India receive timely and quality care is critical. Rising healthcare expenses and limited access to immediate funds can delay treatment when it is needed most. Opting for a reliable health insurance plan can help ease this burden. Exploring Niva Bupa’s NRI health insurance plans offers financial protection, access to a wide hospital network, and smoother cashless treatment, ensuring that loved ones receive uninterrupted medical care.

FAQs

1. Is von Willebrand disease a terminal condition?

This condition can vary widely from person to person. Some individuals may experience mild, manageable symptoms, while others may face more severe complications that require ongoing medical care. Because of this variation, the severity and long-term impact of the disease differ for each individual, rather than being uniformly life-threatening. 

2. Can von Willebrand disease be cured?

This medical condition does not have a permanent cure or solution. However, there are treatments available to help manage the symptoms. These treatment options can also prevent one from suffering an increased bleeding tendency in case of injury or medical procedures. 

3. Is von Willebrand disease hereditary?

Yes, the condition is usually inherited from one or both parents due to genetic mutations affecting the clotting protein.

4. Can women experience more symptoms than men?

Yes. Women may experience additional symptoms such as excessive menstrual bleeding due to hormonal and reproductive factors.

5. How is von Willebrand disease diagnosed?

Doctors typically diagnose the condition through specialised blood tests that measure clotting factors and the levels of clotting protein in the blood.

6. Are von Willebrand disease and haemophilia the same?

No. While this disease is related to haemophilia, they are not the same. And while both diseases are genetic bleeding disorders, the way they're inherited is different. Even the genes involved are not exactly the same.
