Von Willebrand Disease Management

Introduction

If you or someone in your family has been told you have von Willebrand disease — often shortened to VWD — you are probably trying to understand what the diagnosis really means day to day. Will you need treatment every day? Is surgery safe? What about pregnancy, periods, sports, or passing it on to children? These are reasonable questions, and most have reassuring answers.

Von Willebrand disease is the most common inherited bleeding disorder in the world. It affects roughly 1 in 100 people when measured by blood tests alone, although only about 1 in 1,000 has bleeding symptoms noticeable enough to need medical care. Most people with VWD have a mild form. With the right plan from a hematologist (a doctor who specialises in blood disorders), the great majority lead full, active lives and need treatment only at certain times — before surgery, during heavy periods, after injuries, or around childbirth.

Von Willebrand disease is a condition in which the blood does not clot as well as it should. The problem lies with a protein in the blood called von Willebrand factor, named after Dr Erik von Willebrand, the Finnish doctor who first described the condition in the 1920s.

Von Willebrand factor (VWF) does two important jobs in the clotting system:

• It helps tiny blood cells called platelets stick to the wall of an injured blood vessel, so they can plug the leak.
• It carries and protects another clotting protein called factor VIII, which is needed for the next step of clot formation. Without enough VWF, factor VIII gets broken down too quickly.

In von Willebrand disease, one of two things has gone wrong: either the body makes too little VWF, or it makes VWF that does not work properly. When that protein is missing or faulty, small leaks in blood vessels take longer to seal. This is why people with VWD tend to bleed longer from cuts, bruise easily, have nosebleeds, or bleed heavily after dental work, surgery, or childbirth.

VWD is almost always inherited — passed down through families in the genes. It is not contagious, not caused by diet or lifestyle, and is not the patient’s or parent’s fault. A very small number of people develop a similar condition later in life called acquired von Willebrand syndrome, which is linked to other health problems rather than genes.

Types of Von Willebrand Disease

VWD is not a single condition. International guidelines from the American Society of Hematology (ASH), the International Society on Thrombosis and Haemostasis (ISTH), the National Hemophilia Foundation (NHF), and the World Federation of Hemophilia (WFH) describe three main types, each managed differently. Knowing the exact type is important because it shapes which treatments work.

Type 1

This is the most common form, affecting about 75% of people with VWD. The body makes von Willebrand factor, but not enough of it. The protein itself works normally. Most people with Type 1 have mild to moderate bleeding symptoms — nosebleeds, easy bruising, heavy periods, longer bleeding after dental work. Many people with Type 1 manage well without any daily treatment.

Type 2

In Type 2, the body makes a normal amount of von Willebrand factor, but the protein does not work properly. Type 2 is further divided into sub-types — called 2A, 2B, 2M, and 2N — based on exactly which part of VWF’s job is affected. The differences matter because some treatments that work well in Type 1 are not suitable for certain Type 2 sub-types. Bleeding symptoms in Type 2 are usually more noticeable than in Type 1.

Type 3

Type 3 is the rarest and most severe form. The body produces almost no von Willebrand factor at all, and factor VIII levels are also very low. People with Type 3 may have frequent, sometimes severe bleeding, including joint and muscle bleeds similar to those seen in haemophilia. Type 3 usually requires more active, planned management throughout life.

Acquired von Willebrand syndrome

This is not inherited. It develops later in life, usually in connection with another condition — certain heart valve problems, some cancers of the blood or lymph system, autoimmune disease, or an underactive thyroid. Treatment focuses on the underlying cause as well as on bleeding control.

Causes and Risk Factors

Inherited VWD is caused by changes (mutations) in the gene that tells the body how to make von Willebrand factor. The gene is found on chromosome 12, and a child can inherit a faulty copy from one or both parents.

• If a child inherits one faulty gene from one parent, the result is usually Type 1 or Type 2 VWD. This pattern is called autosomal dominant inheritance.
• If a child inherits a faulty gene from both parents, the result is usually Type 3, which is more severe. This pattern is called autosomal recessive inheritance.

Because the gene is on a non-sex chromosome, VWD affects men and women in roughly equal numbers. However, women are more likely to notice symptoms because of heavy periods and childbirth.

The main risk factor for VWD is a family history of bleeding problems — relatives with heavy nosebleeds, prolonged bleeding after surgery or dental work, heavy periods, or a previously diagnosed bleeding disorder. Some people, however, are the first in their family to be diagnosed because earlier generations had mild symptoms that were dismissed as “just heavy periods” or “a tendency to bruise.”

Certain factors can temporarily raise VWF levels in the blood — including pregnancy, exercise, stress, and oral contraceptives — which is why levels can vary from one test to another and why diagnosis sometimes needs repeat testing.

Signs and Symptoms

If you are reading this with a diagnosis already in hand, you are likely familiar with at least some of these. This section is included to help you recognise patterns that may signal a need to contact your hematologist — not to teach first-time symptom recognition.

Bleeding symptoms in VWD tend to come from the surfaces of the body — nose, mouth, gums, skin, the lining of the uterus, the digestive tract — rather than deep inside joints (which is more typical of haemophilia, although severe Type 3 VWD can cause joint bleeds too).

Common patterns include:

• Frequent or long-lasting nosebleeds, particularly those lasting more than 10 minutes or needing medical help
• Easy bruising, often with bruises larger than a coin or appearing without clear injury
• Prolonged bleeding from small cuts
• Heavy or prolonged menstrual periods (more than 7 days, soaking through pads or tampons quickly, or passing large clots)
• Bleeding from the gums after brushing or dental work
• Heavier than expected bleeding after surgery or childbirth
• Iron deficiency or anaemia from ongoing blood loss, sometimes felt as tiredness

Less common, usually in more severe forms:

• Blood in stool or urine
• Joint or muscle bleeding
• Bleeding inside the head after a knock (rare but serious)

Patterns can change over time. Periods may become heavier in some life stages and lighter in others. Pregnancy often raises VWF levels temporarily. Older patients with VWD sometimes develop new gastrointestinal bleeding patterns that need investigation. If bleeding episodes become more frequent, last longer, or change in character, this is a reason to contact your hematology team.

How Von Willebrand Disease Is Diagnosed

VWD can be tricky to diagnose for two reasons. First, the symptoms overlap with other conditions and with normal variation — many people have an occasional nosebleed or a heavy period. Second, VWF levels in the blood naturally rise and fall, so a single normal test does not rule out VWD.

The 2021 international guidelines on diagnosis recommend a stepwise approach.

Bleeding history and bleeding score

The doctor usually begins with a careful conversation about your own bleeding pattern, your family history, and any medications you take. Many hematology clinics use a structured questionnaire called a bleeding assessment tool (BAT) that produces a score reflecting how unusual your bleeding pattern is.

Initial blood tests

If VWD seems possible, the next step is a panel of blood tests that usually includes:

• VWF antigen — measures how much VWF protein is in the blood
• VWF activity (often measured by a test called ristocetin cofactor activity, or by newer assays) — measures how well the protein works
• Factor VIII level — because factor VIII rides along with VWF
• A full blood count and platelet count
• Standard clotting tests such as PT and APTT

Sub-type testing

If the initial tests suggest VWD, further specialised tests help identify the exact type and sub-type. These can include VWF multimer analysis, collagen binding, platelet binding tests, and factor VIII binding. In some cases, genetic testing of the VWF gene is used to confirm the diagnosis or guide treatment, particularly when the result will affect family planning or surgical management.

Blood group note

People with blood group O naturally have lower VWF levels than those with groups A, B, or AB. This is normal variation and not a disease, but it means your blood group is sometimes considered when interpreting borderline results.

Treatment and Management

There is no cure for inherited VWD. The goal of treatment is to prevent and control bleeding while letting you live as normally as possible. Most people do not need any daily medication. Instead, treatment is used at specific times — before a planned procedure, during heavy periods, after an injury, or for severe bleeding. People with Type 3 or with frequent bleeds may use regular preventive treatment, called prophylaxis.

Desmopressin (DDAVP)

Desmopressin is a synthetic version of a natural hormone. It works by triggering the body to release its own stored von Willebrand factor and factor VIII into the bloodstream. It can be given as an injection or as a nasal spray.

Desmopressin works best in many people with Type 1 VWD and in some sub-types of Type 2. It usually does not work in Type 3 because there is little stored VWF to release. In Type 2B specifically, desmopressin may worsen platelet counts and is generally avoided. Before relying on desmopressin for a surgery or procedure, hematologists often arrange a trial dose with blood tests afterwards to confirm the patient responds.

Side effects can include facial flushing, headache, low sodium levels with fluid retention, and (rarely) seizures from low sodium — which is why fluid intake is usually restricted around the time of dosing.

Von Willebrand factor concentrates

When desmopressin is not suitable, or when bleeding is more serious, treatment involves giving VWF directly into the bloodstream through a drip or injection. Two main kinds of concentrates are used:

• Plasma-derived VWF/factor VIII concentrates — made from carefully screened and treated donated plasma, containing both VWF and factor VIII
• Recombinant VWF — made in the laboratory without using human plasma, containing pure VWF

These concentrates are used to prevent bleeding around surgery or childbirth, to treat bleeding episodes, and as long-term prophylaxis for people with severe disease or frequent bleeds.

Antifibrinolytic medicines

Drugs such as tranexamic acid and aminocaproic acid help stabilise clots once they form by preventing the body from breaking them down too quickly. They are particularly useful for bleeding from surfaces lined with mucous membrane — nosebleeds, mouth bleeding, dental procedures, and heavy periods. They can be used alone for mild bleeds or alongside desmopressin or VWF concentrates for bigger ones.

Hormonal treatment for heavy periods

Heavy menstrual bleeding is one of the most disruptive symptoms of VWD for many women. Options that hematologists and gynaecologists commonly discuss include the combined oral contraceptive pill, progesterone-only pills, and the levonorgestrel intrauterine system (a hormone-releasing IUD). For some, a combination of hormonal treatment and tranexamic acid taken during periods works well. The right choice depends on age, family-planning wishes, other medical conditions, and personal preference.

Medications and substances to avoid

People with VWD are generally advised to avoid medicines that further interfere with platelet function or clotting, unless a doctor specifically advises otherwise. These include:

• Aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen
• Certain herbal supplements that affect bleeding, such as high-dose fish oil, ginkgo, garlic supplements, and ginseng
• Anticoagulant medicines, unless prescribed for a specific medical reason and carefully balanced against bleeding risk

Paracetamol (acetaminophen) is generally safe for pain relief. Always tell any new healthcare provider — including dentists, pharmacists, and emergency staff — about your VWD before they prescribe or recommend a medication.

Treatment for acquired von Willebrand syndrome

When VWD is acquired rather than inherited, managing the underlying condition (for example, a heart valve problem or a blood disorder) is often the main path to controlling bleeding. Short-term measures with desmopressin, VWF concentrates, tranexamic acid, or specialised treatments such as intravenous immunoglobulin may be used as well.

Planning for Surgery, Dental Work, and Procedures

One of the most important aspects of VWD management is planning ahead for any procedure that could cause bleeding. This includes obvious operations but also smaller events such as tooth extractions, biopsies, endoscopies, and even some injections.

Standard planning usually includes:

• Letting the hematology team know well in advance — ideally weeks before a planned procedure
• Confirming your VWD type and severity, with up-to-date blood tests if needed
• Agreeing a treatment plan: desmopressin, VWF concentrate, tranexamic acid, or a combination, with specific doses and timing
• Arranging the treatment to be available at the hospital or clinic where the procedure will happen
• Planning post-procedure monitoring for delayed bleeding, which can occur several days after surgery
• Carrying a clear written summary of the plan and your diagnosis

For dental work, even routine cleanings sometimes need a short course of tranexamic acid mouthwash or tablets. Extractions and gum surgery usually need a more detailed plan.

Pregnancy and Childbirth

Many women with VWD have safe pregnancies and healthy babies. VWF and factor VIII levels typically rise during pregnancy — sometimes into the normal range — which lowers bleeding risk during delivery itself. However, levels fall quickly after birth, and the risk of heavy bleeding (called postpartum haemorrhage), particularly delayed bleeding in the days and weeks after delivery, is higher than for women without VWD.

Good pregnancy care for VWD usually includes:

• Early discussion with both a hematologist and an obstetrician, ideally before pregnancy
• Blood tests in the third trimester to check VWF and factor VIII levels
• A written delivery plan agreed with the maternity team, covering pain relief options (some forms of spinal/epidural anaesthesia may need specific levels), treatment availability during labour, and management of delivery
• A clear plan for the postpartum period, including extended use of tranexamic acid and, in some cases, VWF concentrate
• Awareness of the baby’s possible diagnosis if VWD is suspected to be passed on, with appropriate testing arrangements

Genetic counselling is available for couples who want to understand the chances of passing VWD on, particularly when both partners may carry the gene or when severe Type 3 VWD is present in the family.

Lifestyle and Self-Management

Living with VWD does not mean avoiding life. Most activities are safe with some sensible adjustments.

Physical activity and sport

Regular exercise is encouraged. Most non-contact sports — walking, swimming, cycling, yoga, dancing, gym training — are generally fine for people with mild and moderate VWD. Doctors typically advise more caution with high-impact contact sports (boxing, rugby, martial arts) for people with moderate to severe disease, because head injury and joint bleeds carry more risk. The right level of activity depends on your type of VWD and a conversation with your hematology team.

Personal preparation

• Carry a medical alert card, bracelet, or note in your phone identifying your VWD type and your treatment centre
• Keep an emergency supply of tranexamic acid or any prescribed medicine if your team has advised this
• Tell new dentists, doctors, and pharmacists about your condition before any procedure or new medicine
• Build a relationship with one main hematology centre if possible, so your records stay together

Diet and iron

There is no special VWD diet, but iron loss from frequent or heavy bleeding can cause iron-deficiency anaemia. A balanced diet that includes iron-rich foods (lean meats, beans, lentils, dark green leafy vegetables, fortified cereals) helps. If anaemia develops, your doctor may prescribe iron supplements or, occasionally, iron infusions. Routine self-prescribing of supplements is not advised because some can affect bleeding.

Travel

Travel is usually fine. Carry a doctor’s letter explaining your diagnosis and listing any medications, particularly if you are crossing borders with injectable treatment. Identify a hematology centre at your destination in advance if possible, especially for long trips or trips to remote areas.

Monitoring and Follow-Up

VWD is a lifelong condition, but for many people the follow-up is not intensive. A typical pattern includes:

• An annual or every-other-year hematology review for stable, mild cases
• More frequent reviews for moderate to severe disease, frequent bleeds, or during pregnancy
• Iron and full blood count monitoring if bleeding is frequent or periods are heavy
• Repeat VWF and factor VIII testing when treatment plans need updating — for example, before surgery, after major life changes, or if symptoms shift
• Family screening conversations if a new diagnosis is made, so close relatives can be assessed if they wish

Some people benefit from being followed at a specialised haemophilia and bleeding disorders treatment centre, which brings together hematology, nursing, physiotherapy, genetics, and dental and obstetric input. For people with Type 3 VWD or recurrent severe bleeding, this team-based care is particularly helpful.

Risks and Complications

When VWD is well managed, most people have few problems. However, possible complications to be aware of include:

• Iron-deficiency anaemia from chronic blood loss, particularly with heavy periods or repeated gastrointestinal bleeding
• Heavy bleeding during or after surgery, childbirth, or dental work, especially if VWD was not known beforehand
• Postpartum haemorrhage, including delayed bleeding days or weeks after delivery
• Joint and muscle damage from repeated bleeds, mainly in severe Type 3 disease
• Allergic reactions or other rare adverse effects from clotting concentrates — modern preparations are highly purified, but reactions still happen occasionally
• Low sodium from desmopressin if fluid intake is not restricted around dosing
• Development of inhibitors — antibodies that block infused VWF — which is rare but more likely in Type 3 disease

Most of these can be prevented or limited with a good treatment plan and early communication with the hematology team when problems arise.

Living with Von Willebrand Disease

Most people with VWD describe daily life as fairly normal once they understand their condition and have a plan. The mental load — remembering to mention VWD to every dentist, planning ahead for events, monitoring periods or bruises — is real, but tends to ease with time and experience.

Common practical themes that people raise include:

• School and work: most schools and workplaces accommodate VWD easily. Sharing the diagnosis with a school nurse or occupational health team helps when adjustments are needed (for example, around contact sports or after a head bump).
• Emotional impact: some people, particularly young women with heavy periods or parents of newly diagnosed children, find the early months stressful. Patient organisations and peer-support groups for bleeding disorders can help.
• Relationships and family: open conversations with partners about treatment, pregnancy planning, and shared decision making are valuable. Genetic counselling is available for couples thinking about children.
• Long-term outlook: with appropriate care, life expectancy in VWD is generally normal, and most people retain a high quality of life.

Von Willebrand Disease in Children

Many people with VWD are diagnosed in childhood, often after a tooth extraction, a tonsillectomy, or repeated nosebleeds bring attention to the problem. Other children are diagnosed because a parent or sibling already has VWD and family screening is offered.

Recognising VWD in children

Suggestive features that may prompt a hematologist to test for VWD include:

• Frequent or hard-to-stop nosebleeds, particularly bilateral nosebleeds lasting more than 10 minutes
• Bruising that seems out of proportion to bumps and falls, often in unusual places
• Prolonged bleeding after small cuts, immunisations, or losing a baby tooth
• Heavy menstrual bleeding from the first or second period in adolescent girls
• A family history of VWD or unexplained bleeding

Diagnosis in children

Testing in children follows the same principles as in adults, but VWF levels in newborns and very young infants can be naturally higher, which can mask mild VWD. Repeat testing later in childhood is sometimes needed. Genetic testing may be offered when the family pattern is known.

Treatment in children

Most children with mild VWD do not need any daily treatment. Tranexamic acid is widely used for mucosal bleeds — nose, mouth, dental. Desmopressin can be used in children, often from around age 2 or 3 upward depending on the centre and the situation, with careful attention to fluid intake. VWF concentrates are used for more severe bleeds, surgery, or Type 3 disease. Adolescent girls with heavy periods may be offered a combination of tranexamic acid and hormonal treatments after a joint hematology and gynaecology discussion.

Daily life for children with VWD

• Most non-contact sports and school activities are safe. Helmets and protective gear are advised for cycling, skating, and similar activities.
• Schools usually appreciate a short written plan from the hematology team describing the diagnosis, what to do for a nosebleed or injury, and emergency contacts.
• Routine immunisations are given as normal. Pressure on the injection site afterwards reduces bruising; intramuscular injections are sometimes given with extra care.
• Dental care is important — good oral hygiene reduces the need for procedures. Dental work, including extractions, is planned with the hematology team.
• Parents are usually advised to seek prompt review for head injuries, persistent vomiting after a bump to the head, large bruises that grow, or any bleeding that does not stop with standard first aid.

With age, many children and teenagers take over more of their own VWD care, learning to recognise when to use tranexamic acid, when to call their team, and how to explain the condition to others.

When to Seek Urgent Care

Most bleeding in VWD can be managed at home or with planned hematology input. However, some situations need urgent medical assessment. Contact your hematology team or go to an emergency department for:

• A head injury with loss of consciousness, persistent vomiting, severe headache, drowsiness, or confusion
• A nosebleed that does not stop after 20 minutes of firm pinching pressure
• Bleeding that is soaking through dressings or sanitary protection rapidly and not responding to usual measures
• Blood in vomit, stool (black or red), or urine
• Sudden severe pain or swelling in a joint or muscle without clear injury
• Heavy postpartum bleeding or bleeding that returns days or weeks after childbirth
• Signs of severe anaemia — chest pain, breathlessness, fainting, or extreme fatigue

Always carry information about your VWD type and any treatments you use, so the team caring for you in an emergency can plan quickly.

Frequently Asked Questions

Is von Willebrand disease the same as haemophilia?

No. Both are inherited bleeding disorders involving the clotting system, but they affect different proteins. Haemophilia involves factor VIII or factor IX directly and tends to cause deep bleeds into joints and muscles. VWD mostly causes bleeding from skin and mucous membranes — nose, mouth, periods. VWD affects men and women roughly equally; classic haemophilia mainly affects men.

Can VWD be cured?

Inherited VWD cannot currently be cured. It can be very effectively managed, and many people need treatment only at specific times. Research into longer-acting therapies and gene therapy for bleeding disorders is ongoing.

Will my child definitely have VWD if I do?

Not necessarily. The chance depends on the type. With Type 1 or most Type 2, each child has roughly a 50% chance of inheriting the faulty gene from an affected parent, though not every child who inherits the gene will have noticeable symptoms. Type 3 usually requires inheriting a faulty gene from both parents. Genetic counselling can give a personalised picture for your family.

Can I take ibuprofen or aspirin?

Aspirin, ibuprofen, and similar NSAIDs are generally avoided in VWD because they further reduce platelet function and raise bleeding risk. Paracetamol (acetaminophen) is usually a safer choice for pain or fever. Always check with your hematology team before starting any new medicine.

Will I always need treatment before dental work?

Not always. A routine cleaning may need no special preparation, particularly in mild disease. Extractions, root canals, and gum surgery usually do need a plan — often tranexamic acid alone, sometimes combined with desmopressin or VWF concentrate. The hematology team can advise based on the type of procedure and your VWD severity.

Is it safe to have an epidural during childbirth?

It can be, but it depends on VWF and factor VIII levels at the time of delivery. Many women with mild VWD whose levels rise into the normal range during pregnancy can safely have an epidural after consultation between the hematology, obstetric, and anaesthetic teams. Planning ahead is essential.

Do I need to take treatment every day?

Most people with VWD do not. Mild and many moderate cases need treatment only around bleeds, periods, or procedures. Regular preventive treatment (prophylaxis) is mainly used for severe Type 3 disease or for people with frequent serious bleeds.

Can I donate blood?

Generally no — people with diagnosed bleeding disorders are usually not eligible to donate blood because of the risks during and after donation. Specific rules vary by blood service.

Conclusion

Von Willebrand disease is a lifelong condition, but it is one of the more manageable inherited bleeding disorders. Most people have mild disease, need treatment only at specific times, and live full lives with minimal day-to-day disruption. Even people with more severe forms can do well with planned, team-based care.

The keys to good outcomes are clear: an accurate diagnosis including the exact type, a written treatment plan that you and your hematology team agree on, planning ahead for procedures and pregnancies, and a healthcare team that can be reached when symptoms or situations change. With these in place, von Willebrand disease becomes a condition you live with rather than one that controls your life.
