Haemophilia

Haemophilia is a rare condition that affects the blood's ability to clot. It's usually inherited, and most people who have it are male. There’s no cure, but with treatment you can live a normal life. See your GP if you or your child have symptoms of haemophilia (see below).

Symptoms of haemophilia

Normally, when you cut yourself, substances in the blood known as clotting factors combine with blood cells called platelets to make the blood sticky. This makes the bleeding stop eventually.

People with haemophilia don't have as many clotting factors in their blood. This means they bleed for longer than usual.

The symptoms of haemophilia can be mild to severe, depending on the level of clotting factors you have.

The main symptom is bleeding that doesn't stop, also called prolonged bleeding.

People with haemophilia may have:

  • nosebleeds that take a long time to stop
  • bleeding from wounds that lasts a long time
  • bleeding gums
  • skin that bruises easily
  • pain and stiffness around joints, such as elbows, because of bleeding inside the body (internal bleeding)

When to get medical advice

See your GP if:

  • you or your child bruises easily and has bleeding that doesn't stop
  • your or your child has symptoms of joint bleeds – for example, tingling, pain, or stiffness in the joint, and the joint becoming hot, swollen, and tender
  • you have a family history of haemophilia and you're pregnant or planning to have a baby

There's a small risk people with haemophilia may have a bleed inside their skull.

Symptoms of this include:

Call 999 for an ambulance if someone has these symptoms.

Tests and diagnosis

Blood tests can diagnose haemophilia and find out how severe it is.  If there's no family history of haemophilia, it's usually diagnosed when a child begins to walk or crawl. 

Mild haemophilia may only be discovered later, usually after an injury or a dental or surgical procedure.

Genetic tests and pregnancy

If you have a family history of haemophilia and you're planning to get pregnant, genetic testing and counselling can help determine the risk of passing the condition on to a child.

This may involve testing a sample of your tissue or blood to look for signs of the genetic mutation that causes haemophilia.

Tests during pregnancy can diagnose haemophilia in the baby. There's a small risk of these procedures causing problems such as miscarriage or premature labour. You may want to discuss this with your doctor.

If haemophilia is suspected after your child's born, a blood test can usually confirm the diagnosis. Blood from the umbilical cord can be tested at birth if there's a family history of haemophilia.

Treatments for haemophilia

There's no cure for haemophilia, but treatment usually allows a person with the condition to have a good quality of life.

Genetically engineered clotting factor medicines are used to prevent and treat prolonged bleeding. These medicines are given as an injection. 

In milder cases, injections are usually only given in response to prolonged bleeding. More severe cases are treated with regular injections to prevent bleeding.

Living with haemophilia

With treatment, most people with haemophilia can live a normal life.

However, you should:

  • avoid contact sports, such as rugby
  • be careful taking other medicines – some can affect your blood's ability to clot, such as aspirin and ibuprofen 
  • maintain good oral hygiene and have regular trips to the dentist

Looking after your teeth and gums helps avoid problems such as gum disease, which can cause bleeding. Most non-surgical dental treatment can be carried out at a general dental practice.

Your care team at the hospital can offer advice about surgical dental procedures, such as having a tooth removed, and further information and advice about living with haemophilia.
