You've probably heard, "Oh, that young man suddenly had a blood clot." Or have you ever had your own leg suddenly swell up and hurt? Today we're going to talk about a condition called 'Thrombophilia' that can sometimes cause things like this. Don't be scared when you hear this name, this is a condition that many people can have. That's why it's very important to be aware of it.
Simply put, what is Thrombophilia?
Thrombophilia is a condition in which your blood clots more easily and more quickly than normal blood. Doctors call this a 'hypercoagulable' condition. This means that your blood has an increased ability to clot. This can be genetic or acquired. Now imagine what happens when you cut your hand with a knife? A little blood is lost, and after a while a blood clot forms at that site and the bleeding stops. It is actually a protective process in our body. After the wound heals, the body dissolves the blood clot again and removes it. But something else happens to someone with Thrombophilia. Even when the body doesn't need it, blood clots form in the veins. Or, the blood clots that form are not dissolved and removed properly. The big problem is when these blood clots travel along the veins and block a blood vessel leading to an important organ. Because every cell in our body gets the oxygen it needs from the blood. If an artery becomes blocked, it cannot carry oxygen. This can lead to serious conditions like
heart attack and stroke .
There are two main types of thrombophilia:
As we mentioned earlier, this condition can be divided into two main types based on how it occurs. 1.
Acquired Thrombophilia: This is the most common type. It is not something that is inherited. It can be caused by certain medications we take, our lifestyle, or other diseases. The most common and severe of these types is
Antiphospholipid Syndrome . 2.
Inherited Thrombophilia (Genetic/Inherited Thrombophilia): This is a genetic condition that you get from your mother, father, or both. There are proteins in our body that control blood clotting. Due to these genetic changes, those proteins may not work properly. Or the body may produce less of the proteins that stop blood clotting.
If you have had blood clots before the age of 40, have had several miscarriages , or if someone in your family has a history of blood clots, you may also have this inherited thrombophilia.
What are the subtypes of congenital thrombophilia?
There are different types of this genetic condition. Let's look at some of the main types.
| Genetic Thrombophilia Type | A simple explanation about it |
|---|
| Factor V Leiden Thrombophilia | This is the most common of the genetic variants. It affects 1% to 5% of the population. It increases the risk of developing a blood clot in a deep vein in the leg (Deep Vein Thrombosis - DVT) for the first time. |
| Prothrombin Thrombophilia | This is the second most common type. There is a higher risk of pulmonary embolism, DVT, and miscarriage. |
| Protein C Deficiency | This is a bit rare. There is a high risk of recurrent blood clots. If this condition is inherited from both parents, it can even be life-threatening. |
| Protein S Deficiency | This is also rare. An even rarer form (inherited from both parents) can cause life-threatening blood clotting problems in newborns. |
| Antithrombin Deficiency | This is also rare (occurring in 1 in 500 to 5,000 people). But people with this condition are at a much higher risk of developing blood clots than people with other genetic conditions. More than 80% of people with this condition will develop at least one blood clot by the age of 50. |
What are the symptoms of a blood clot?
Most of the time, you may not even know you have thrombophilia. The problem only arises when a blood clot forms and symptoms appear. These symptoms vary depending on where the clot has formed.
| Body part | Symptoms to expect |
|---|
| Brain | - Seizures
- Sudden, severe headache
- Difficulty speaking and seeing
- Feeling of numbness on one side of the body
|
| Heart | |
| Lungs | |
| Leg or Arm | - Sudden swelling
- Severe pain
- Feeling warm to the touch
|
| Belly | |
What are the causes and risk factors for developing thrombophilia?
In addition to genetic causes, many other causes and risk factors can cause thrombophilia or increase the risk of blood clots.
Main reasons:
- Antiphospholipid Syndrome
- Disseminated Intravascular Coagulation (DIC), a rare blood disorder
- Hepatitis
- HIV infection
- Liver disease
Factors that increase risk:
- Overweight: Obesity is a major risk factor for blood clots.
- Pregnancy: Hormonal changes in the body during pregnancy naturally increase the tendency for blood to clot.
- Use of tobacco products: Smoking damages blood vessels and makes it easier for blood clots to form.
- Other diseases: Conditions such as diabetes, cancer, heart disease, and atherosclerosis.
- Staying in the same position for long periods of time: When staying in the hospital after surgery, on a long flight or bus ride, or when sitting at work, blood circulation in the legs can decrease and blood clots can form.
- Undergoing surgery.
- Taking birth control pills or hormone replacement therapy (HRT) that contain the hormone estrogen.
- Having a family history of blood clots.
- Aging.
- Miscarriages for which no cause can be found.
- Having more than one blood clot before the age of 40.
Remember, just because you have one or more of these risk factors doesn't mean you will develop a blood clot. But it's important to be aware of them and follow your doctor's advice.
How do I find out if I have this condition?
When you have a blood clot and are being treated for it, your doctor may suspect thrombophilia. They will then run several tests to confirm the condition.
- Your medical history: You will be asked about any previous blood clots, whether anyone in your family has had them, or whether you have had any miscarriages.
- Physical Exam: Checks for swelling and pain caused by a blood clot.
- Blood Tests: Special blood tests are done to look for genetic conditions or other protein deficiencies that cause thrombophilia.
- Other tests: Tests such as ultrasound scans, CT scans , or angiograms may be done to find the exact location of the blood clot.
Who should take this test?
These tests are not usually done for everyone. Your doctor may order these tests in the following situations:
- If you had a blood clot before the age of 50.
- If several people in your family have a history of blood clots.
- If a blood clot forms without any obvious risk factors.
- If blood clots form in unusual places (e.g., arms, abdomen).
- If you have frequent miscarriages.
- If you want to know if your family is at risk.
What are the treatments for thrombophilia?
There is no cure for congenital thrombophilia. But it can be
managed well, preventing blood clots and leading a normal life. Treatment options depend on the type of thrombophilia you have, whether a blood clot has formed, and the severity of the condition.
- Anticoagulants: These are the main treatment. These medications work by preventing new blood clots from forming and by slowing down the growth of existing clots. Heparin and Warfarin are older medications. Newer medications are now available that are easier to take. Some people may have to take these medications for the rest of their lives.
- Thrombolytics: These are used only in emergencies and serious cases. For example, if a large blood clot in the lungs is life-threatening, these drugs can be given intravenously to quickly dissolve the clot.
- Compression Stockings: Your doctor may advise you to wear these special types of stockings to reduce swelling and maintain good blood circulation, especially for those who have blood clots in their legs.
- Surgery: Very rarely, if a large blood clot cannot be dissolved with medication, surgery may be needed to remove it.
Things we can do to reduce the risk
If you know you have thrombophilia, or are at risk of developing blood clots, it is very important to change your lifestyle.
- Avoid smoking completely.
- Maintain a healthy body weight.
- Exercise regularly. Even something as simple as walking is good to do every day.
- On long journeys: If you are traveling on a plane or bus for a long time, get up every hour or two and walk around a bit, shaking your legs.
- After surgery: Get out of bed and start walking as soon as your doctor allows you to.
- Medications containing estrogen: If you are taking medications containing estrogen, such as birth control pills, talk to your doctor about this risk. He or she will be able to recommend a suitable alternative for you.
- Doctor's advice: If you are taking blood-thinning medication, take it at the right time and in the right dosage. Never stop taking the medication without consulting your doctor.
When to see the doctor
If you have thrombophilia, it is important to maintain regular contact with your doctor and to act quickly if any symptoms appear.
When to seek medical advice: See your doctor or
go to the hospital's Emergency Treatment Unit (ETU) immediately. - New swelling, pain, or redness in a leg or arm.
- Abnormal bleeding, such as nosebleeds, blood in urine or stool, due to blood-thinning medications.
- If you have any doubts or questions about your situation.
|
- Sudden severe chest pain or difficulty breathing (these may be signs of a heart attack or pulmonary embolism).
- Sudden severe headache, difficulty speaking, or weakness on one side of the body (these may be signs of a stroke).
- Heavy, continuous bleeding caused by a cut.

Take-Home Message
- Thrombophilia is a condition in which the blood clots more easily and quickly than normal. This can be something that is present at birth or something that develops later in life.
- Many people with this condition live without developing any blood clots. Symptoms only occur if a blood clot forms inside a vein and blocks blood flow.
- A blood clot can be serious if it forms in the brain, heart, lungs, or legs, so it's important to be aware of the symptoms.
- Although this condition cannot be completely cured, it can be managed well and the risk reduced by taking medication as prescribed by your doctor and following a healthy lifestyle.
