Blood clots are a serious health concern that can have life-threatening consequences, such as stroke or pulmonary embolism. 

However, there are several preventive measures that individuals can take to reduce their risk of developing blood clots. 

By following these practical tips, you can empower yourself with knowledge and take proactive steps toward safeguarding your well-being from the dangers associated with blood clotting.

What is a Blood Clot?

A clot, also known as a blood clot or thrombus, is a gel-like mass formed by platelets and fibrin in the blood. It is an essential part of the body’s natural defense mechanism to prevent excessive bleeding when an injury occurs.

When a blood vessel gets damaged, whether it’s due to trauma or internal causes such as inflammation or disease, the body initiates a series of events to stop the bleeding. 

Platelets, which are small cell fragments in the blood responsible for clotting, rush to the injury site and start sticking together. They form a temporary plug that helps prevent further blood loss.

However, this initial platelet plug alone may not be sufficient to completely seal off the damaged area. This is where fibrin comes into play. 

Fibrin is a protein that forms long strands around the platelet plug, creating a mesh-like structure called a fibrin network. 

As more and more platelets get trapped within this network, it strengthens and stabilizes the clot.

Risk Factors

According to the American Heart Association, common risk factors include:

1. Sedentary Lifestyle

Leading a predominantly sedentary lifestyle can significantly increase the risk of developing blood clots. 

This is because sitting or lying down for prolonged periods restricts normal

circulation, allowing blood to pool in veins and increasing clotting chances. 

Individuals working desk jobs or spending extended hours sitting during travel should incorporate regular breaks and physical activity into their routines.

2. Obesity

Obesity has been identified as a significant risk factor for various health conditions, including blood clots. 

This is because excess weight puts additional pressure on veins and restricts proper circulation, leading to an increased chance of clot formation.

Research shows that maintaining a healthy weight through regular exercise and balanced nutrition helps reduce this risk factor.

3. Smoking

Cigarette smoking damages blood vessels and increases clotting tendencies by altering platelet function and promoting inflammation within arteries. 

The chemicals present in tobacco also contribute to the thickening of the arterial walls, amplifying the risks further.

4. Age

As individuals age, their risk of developing blood clots increases due to various physiological changes within their bodies. 

Aging causes decreased mobility, weaker vein valves, thicker arterial walls, and slower metabolism, which may lead to obesity, all potentially contributing to clot formation.

5. Hormonal Contraceptives

Certain hormonal contraceptives may slightly elevate the risk of developing blood clots due to their impact on hormone levels within the body. 

For example, birth control pills containing estrogen pose a higher risk than progesterone-only options. This is because estrogen increases the level of clotting factors in the blood.

That being said, research shows that the risk is relatively small, with only one in 3000 women on birth control pills developing blood clots per year.

However, women with a previous history of blood clots or an inherited thrombophilia have a greater risk. This calls for proper consultation when deciding on a birth control method.

6. Cancer Treatment

Patients undergoing cancer treatment may face an increased risk of developing blood clots due to chemotherapy-induced damage to the inner lining of veins (endothelium), tumor-related inflammation promoting hypercoagulability (excessive clotting), or immobilization resulting from debilitation caused by the disease itself. 

In fact, research shows that blood clots are the most common cause of morbidity and mortality in cancer patients.

Close monitoring by healthcare professionals during cancer treatment helps detect and manage potential clotting risks effectively.

7. Pregnancy and Childbirth

During pregnancy, several factors increase the risk of developing blood clots. These include changes in blood composition, reduced blood flow due to pressure on veins by the growing uterus, and increased levels of clotting factors.

After childbirth (particularly after cesarean section), the risk remains elevated due to postpartum immobility or injury during delivery. Knowledge about preventive measures is crucial for expectant mothers.

8. Previous Blood Clot History

Individuals who have previously experienced blood clots are at an increased risk of developing future ones.

Conditions that contribute to recurrent clot formation include deep vein thrombosis (DVT), pulmonary embolism (PE), atrial fibrillation (AFib), or certain genetic disorders that affect blood coagulation.

Research shows that about 30% of those with deep venous thrombosis or pulmonary embolism have a higher risk of another episode.

So, understanding your personal medical history is essential for taking appropriate precautions.

9. Hormonal Replacement Therapies

Hormonal Replacement Therapies (HRT) involve introducing synthetic hormones into the body to compensate for the declining levels of natural hormones. It is a medical treatment that helps restore the balance of hormones in the body.

These therapies are commonly used to alleviate symptoms associated with hormonal imbalances, particularly during menopause and other hormone-related conditions in women.

However, as I mentioned above, estrogen-based HRT may pose a higher risk of developing blood clots due to its effect on increasing clotting factors in the bloodstream. It is important for women considering HRT to discuss potential risks with their healthcare provider.

10. Surgery and Trauma

Undergoing major surgeries or experiencing severe trauma can trigger blood clot formation due to various reasons, such as tissue damage, reduced mobility during recovery, or changes in coagulation factors following surgical procedures. 

Proper post-operative care involving early mobilization, compression stockings, and prescribed anticoagulant medications can help mitigate these risks.

11. Family History

Genetics can also play a role in developing blood clots, with research showing that having a family history of venous thromboembolism (VTE) or other circulatory disorders significantly raises an individual’s susceptibility toward developing blood clots.

12. Prolonged Immobility

Sitting or lying down for extended periods, such as during long-haul flights or bed rest after surgery, can slow down blood circulation, leading to increased clotting risks.

We have discussed different causes of blood clots, now let’s look at ways to prevent blood clots.

How To Prevent Blood Clots

In most cases, blood clots will not show symptoms until a complication occurs, meaning taking active measures to lower your risk is quite essential.

Here are some recommended methods to help lower your risk.

1. Avoid Smoking

As mentioned, smoking not only damages your lungs but also increases the risk of developing blood clots significantly.

While quitting can be an uphill task, here are a few things that can help

  • Choose a specific date within the next two weeks as your official “quit date.” This will give you time to mentally prepare yourself for the change while also creating a sense of commitment.
  • Recognize the situations, emotions, or activities that typically trigger your urge to smoke so you can develop coping mechanisms.
  • Inform your friends and family about your decision to quit smoking and ask for their support throughout this process. Explore Nicotine Replacement Therapy (NRT):
  • Consider using nicotine replacement products such as nicotine gum, patches, inhalers, or lozenges.
  • Engage in regular physical activity since exercise releases endorphins, which can boost mood and reduce cravings for nicotine.

2. Hydrate Adequately

Proper hydration is essential in maintaining optimal blood flow and reducing the likelihood of clot formation.

When you’re dehydrated, your blood becomes thicker and more susceptible to forming clumps or obstructions.

To stay hydrated, here are important tips to consider:

  • Drink plenty of water throughout the day (at least 8 glasses a day).
  • Limit your consumption of diuretic beverages like caffeine or alcohol that can dehydrate you.
  • Stay aware of your body’s hydration needs, especially during hot weather or intense physical activity.

3. Maintain a Healthy Weight

Here are some strategies to help you maintain a healthy weight:

  • Eat a balanced diet rich in fruits, vegetables, whole grains, and healthy fats
  • Be mindful of the portion sizes you consume during each meal. Use smaller plates or bowls to trick your brain into feeling fuller with less food intake.
  • Incorporate regular physical activity into your routine as it plays a significant role in burning calories and increasing metabolism rates. Aim for at least 30 minutes of moderate-intensity exercise five days a week.
  • Limit processed foods and sugary drinks
  • Get Sufficient Sleep: Sleep deprivation can affect hormone regulation, leading to increased food cravings and reduced energy levels. Aim for a consistent sleep routine of 7-8 hours every night to support your weight loss efforts.

4. Take Breaks During Prolonged Sitting

Set reminders on your phone or use apps that remind you to take regular breaks from prolonged sitting. Aim for a break every 30 minutes to one hour.

Take advantage of break time by standing up and walking around whenever possible. Even a short walk around the office or home can improve circulation levels significantly.

If circumstances prevent leaving your desk area during breaks, try incorporating some discreet exercises:

  • Seated Leg Raises: Lift one leg at a time, keeping it straight and parallel to the ground.
  • Seated Marching: Sit tall and march in place, lifting your knees as high as possible, one at a time.
  • Chair Squats: Stand up from your chair without using your arms for support and sit back down slowly.

5. Use compressions

In some cases, wearing compression stockings may be advisable, especially if you have a history of blood clotting disorders or undergo prolonged periods of sitting or standing.

Compression stockings exert pressure on the legs’ veins, assisting blood flow toward the heart while preventing pooling in the lower extremities. 

6. Take Prescribed Medication

If you have been diagnosed with an underlying condition that increases your risk of developing blood clots, your healthcare provider may prescribe anticoagulant medications such as warfarin or heparin. These drugs help prevent existing clots from growing larger and reduce the formation of new ones.

Certain individuals may also require antiplatelet medication like aspirin to inhibit platelets from sticking together and forming dangerous clots.

To determine your risk of blood clots, consult your healthcare provider. They can assess your medical history, conduct necessary tests, and prescribe appropriate preventive measures.

If prescribed anticoagulants or antiplatelet medications, strictly adhere to the dosage and timing advised by your doctor. Do not skip doses, as it may compromise their effectiveness.

Recognizing The Symptoms Of Blood Clots

Here are some common signs and symptoms associated with blood clots.

Deep Vein Thrombosis (DVT)

Deep vein thrombosis occurs when a clot forms in one of the deep veins, usually in the legs or arms. The following symptoms may indicate DVT:

  • Unexplained swelling, particularly in one leg or arm.
  • Persistent pain or tenderness that may worsen when walking or standing.
  • The skin over the affected area might feel warm to the touch and appear red.

Pulmonary Embolism (PE)

A pulmonary embolism happens when a blood clot breaks off from elsewhere in the body, usually the deep vein in your leg, and blocks an artery supplying your lungs. Some common signs include:

  • Sudden shortness of breath out of nowhere, even without exertion.
  • Sharp chest pain that worsens with deep breaths or coughing.
  • An increased pulse rate despite rest or minimal activity. 


A stroke occurs when a blood clot obstructs an artery carrying oxygen-rich blood to the brain. Key indicators include:

  • Uneven smile or droopy features on one side of the face
  • One-sided numbness or weakness in your arm or leg
  • Slurred speech or difficulty expressing words coherently
  • Trouble seeing with one or both eyes
  • Problems walking or staying balanced or coordinated
  • Dizziness
  • Severe headache that comes on for no reason

If you notice any of these symptoms, it’s good to treat it as an emergency and seek medical intervention immediately.
