Factor Vii Deficiency

Overview

Factor VII deficiency (say "factor seven") is a rare bleeding disorder. Factor VII is one of the proteins in your blood that works like a repair crew — when a blood vessel is cut or damaged, these proteins team up to form a clot and stop the bleeding. If you don't have enough factor VII, or it doesn't work properly, bleeding can take longer to stop than usual. It can be something you are born with (inherited) or something that develops later in life (acquired). It ranges from so mild you never notice it to a serious condition that needs specialist care.

No. The inherited form is very rare, affecting about 1 in 500,000 people. The acquired form (caused by another health problem) is more common, especially in people with liver disease or people taking blood-thinning medicines.

It can affect anyone — any age, sex or ethnic background. The inherited form is present from birth, though it may not be noticed until a person has surgery, a dental procedure, an injury or, for women, heavy periods. The acquired form is more likely in people with liver disease, poor nutrition, serious illness, or people taking blood-thinning medicines.

Symptoms

Common symptoms

• Nosebleeds that take a long time to stop
• Bleeding gums, especially after brushing your teeth
• Bruising more easily than other people
• Bleeding that keeps oozing after a cut, dental work, or surgery
• Heavy or long-lasting menstrual periods
• Blood in the urine or stool
• Bleeding that starts again a day or two after an injury

Symptoms in children

• Bleeding from the umbilical stump (belly button) in a newborn
• Bleeding after circumcision that takes longer than expected to stop
• Frequent nosebleeds or nosebleeds that are hard to stop
• Easy bruising, especially on the legs and arms
• Bleeding after falling over or after dental treatment

Symptoms in older adults

• Longer bleeding after surgery, biopsies or dental work
• Bleeding problems linked to liver disease
• Bruising or bleeding linked to blood-thinning medicines
• Blood in the stool or urine
• Symptoms that seem to appear later in life because of more medical procedures and medicines

Causes

Main causes

• Inherited (genetic): a change in the gene that tells the body how to make factor VII. A child must inherit a changed copy of the gene from both parents to have the condition — parents are usually 'carriers' with no symptoms.
• Acquired: low factor VII caused by another condition, such as liver disease, vitamin K deficiency, poor nutrition, long-term illness, or certain blood-thinning medicines.
• Newborn vitamin K deficiency: babies are born with low vitamin K, which the body needs to make several clotting factors, including factor VII.
• Very rarely, the body's immune system mistakenly attacks its own factor VII.

Risk factors

• Having a family history of factor VII deficiency or a known gene change
• Parents who are close blood relatives (this makes inheriting two changed gene copies more likely)
• Liver disease
• Poor nutrition or long-term poor absorption of food
• Taking blood-thinning medicines
• Being a newborn, especially if vitamin K supplementation was not given

When to see a doctor

See a doctor urgently if:

• Bleeding that won't stop with firm pressure for 10 to 15 minutes
• Any bleeding after a head injury — even if you feel fine
• Vomiting blood, black tarry stools, or blood in the urine
• Sudden severe headache, confusion, or weakness on one side
• Heavy periods that are soaking through protection every hour

Book a routine appointment if:

• You bruise easily or bleed more than you'd expect after small cuts
• You have frequent or hard-to-stop nosebleeds
• You have a family history of a bleeding disorder and want to know your options
• You are planning surgery, a dental procedure, or pregnancy
• Your periods are heavy or last more than 7 days

Diagnosis

Your doctor will start by asking about your bleeding history — how often you bruise, how long nosebleeds last, what happened after past surgeries, dental work or childbirth, and whether anyone in your family has a bleeding disorder. They will then arrange blood tests. A specialist (often a haematologist — a doctor who specialises in blood) will confirm the diagnosis and work out how severe it is.

Tests that may be done

• A routine clotting test called a prothrombin time (PT) — this measures how long your blood takes to clot and is often the first clue
• A specific factor VII level blood test — this measures how much factor VII activity you have and helps grade it as mild, moderate or severe
• Genetic testing to look for the gene change, which can help family members
• Liver function tests, to check for the acquired form
• Vitamin K level checks in some people, especially newborns
• Screening of close family members if an inherited gene change is found

What to expect at your appointment

Most of the diagnosis comes from a few blood tests, so it is usually quick and straightforward. You may be referred to a specialist centre, sometimes called a haemophilia centre, where a team can explain the results and plan your care. Bring a list of all your medicines, including anything you buy over the counter, and note down any bleeding events you remember — this history is genuinely helpful.

Treatment

There is no cure for the inherited form, but it can be managed very well. Treatment depends on how severe your deficiency is and whether you are bleeding or about to have a procedure. Many people with mild factor VII deficiency need treatment only occasionally — for example before surgery or after an injury. People with more severe forms may need a planned care plan from a specialist centre.

Self-care at home

• For a cut: press firmly on the area with a clean cloth for at least 10 to 15 minutes without peeking
• For a nosebleed: sit up, lean slightly forward, pinch the soft part of your nose and hold for 10 to 15 minutes
• Use a soft toothbrush and ask your dentist about gentle flossing to protect your gums
• Carry a medical ID card or wear a medical alert bracelet that says you have a bleeding disorder
• Tell every doctor, dentist and surgeon about your condition well before any procedure
• Ask your pharmacist before taking any over-the-counter painkiller, as some can increase bleeding
• Keep the contact details of your specialist centre or haematology team somewhere you can find them quickly

Medical treatments

Treatment is planned by a specialist team and is given only when it is needed. Options include replacing the missing clotting factor through a drip into a vein — either at the hospital or, for some people, at home after training — and medicines that help a clot stay in place instead of breaking down too quickly. People whose deficiency is caused by low vitamin K may be given vitamin K supplements. Dental and surgical procedures are planned in advance with the specialist team, and treatment may be given beforehand to reduce bleeding risk. Your care team will tailor everything to your level of deficiency and your own bleeding pattern.

When is surgery considered?

Surgery, dental work and childbirth all need planning ahead. Tell your surgeon or dentist about your diagnosis as early as possible so the team can arrange any clotting factor treatment you need before and after the procedure. With good planning, most procedures can be done safely.

Living with this condition

Most people with factor VII deficiency live full, ordinary lives. The main practical difference is being prepared: knowing how to stop a nosebleed properly, telling healthcare professionals about your condition, and knowing who to call if bleeding doesn't stop. Keep a simple record of any bleeding episodes so your care team can see the pattern.

Lifestyle tips

• Choose physical activities you enjoy. Swimming, walking, cycling and most team sports are usually fine — ask your care team about contact sports if your deficiency is more severe
• Wear a helmet for cycling and take care with activities where falls are likely
• Avoid smoking and limit alcohol, as both can affect your general health and your liver
• Keep your home stocked with plasters, gauze and a cold pack for nosebleeds
• Let workplaces, schools and sports coaches know what to do if you bleed

Diet and exercise

A balanced diet helps your body make and use clotting factors well. Green leafy vegetables contain vitamin K, which your body needs — you do not need to avoid them, and your care team can advise if your vitamin K levels need attention. Regular gentle exercise keeps your joints and muscles strong, and strong muscles help protect joints from injury. If you have liver disease, your doctor may give specific dietary advice.

Mental health and emotional wellbeing

Living with a rare bleeding disorder can feel worrying at times — you may feel anxious before surgery, dental work or childbirth, or feel that you have to be extra careful all the time. That is completely understandable, and support is available. Talking to your specialist team, a counsellor, or other people with bleeding disorders often helps a great deal. If you ever feel overwhelmed, low, or unable to cope, please reach out to your doctor or a local mental health service. If you feel unsafe or in crisis, contact your local crisis support line or your local emergency number straight away.

Prevention

The inherited form cannot be prevented, because it is written into your genes from birth. However, the acquired form is sometimes preventable. Looking after your liver, eating well, and reviewing blood-thinning medicines with your doctor all help. If you are planning a family and have a family history of the condition, genetic counselling can help you understand the chances and your options.

Vaccines

There is no vaccine for factor VII deficiency. Keeping up with routine vaccinations is still important for your general health, but check with your care team first — some vaccines are given into the muscle, which can cause bruising or bleeding in people with bleeding disorders, so they may recommend a different method or extra pressure afterwards.

Screening programmes

If a gene change has been found in your family, relatives can be offered genetic testing and counselling. All newborn babies are offered vitamin K supplementation shortly after birth to prevent a rare but serious bleeding problem called vitamin K deficiency bleeding — this is a simple and well-established safety measure.

Complications

If left untreated

• Bleeding that goes on longer than it should after injury, surgery or childbirth
• Larger, longer-lasting bruises and nosebleeds that are hard to stop
• Anaemia (low iron in the blood) from repeated or heavy blood loss, causing tiredness and breathlessness
• Rarely, serious bleeding inside the head or gut, which needs emergency care
• Joint damage from repeated bleeding into joints, though this is less common in factor VII deficiency than in some other bleeding disorders
• In newborns, bleeding around the belly button or, rarely, inside the brain if vitamin K is not given

Long-term outlook

The outlook is generally good. Many people with mild factor VII deficiency have a normal life expectancy and few restrictions. People with more severe forms do well when their condition is known, planned for, and managed by a specialist team. The key is knowing your diagnosis, telling healthcare professionals about it before procedures, and acting quickly when bleeding doesn't stop.
