Blood Clots During Pregnancy: Risk Factors & Treatment

Pregnancy causes significant shifts in your body, such as changes in blood flow and clotting processes, to reduce the risk of excessive bleeding during delivery. But these shifts can also raise the risk for blood clots, a condition that can cause serious complications for mother and baby if left unaddressed. Awareness of the dangers, their signs, and preventive measures is critical to safely managing blood clots during pregnancy.

Why Are Blood Clots a Concern During Pregnancy?

Blood clots occur when blood thickens and clumps together, often as part of the body’s natural healing process. However, during pregnancy, the risk of developing abnormal blood clots, such as deep vein thrombosis (DVT), increases due to:

• Hormonal changes: Higher levels of estrogen make the blood more prone to clotting.
• Reduced blood flow: The growing uterus can compress veins, slowing blood circulation, especially in the legs.
• Clotting mechanism changes: Your body naturally increases clotting factors to reduce bleeding risks during labour.

While blood clots are rare during pregnancy, they can lead to complications if they travel to the lungs, causing a pulmonary embolism (PE), a potentially life-threatening condition.

Signs of Blood Clots in Pregnancy

Recognizing the symptoms of blood clots early can prevent severe complications. Common signs include:

Deep Vein Thrombosis (DVT)

DVT is the most common type of blood clot during pregnancy, typically forming in the legs. Symptoms include:

• Swelling in one leg.
• Pain or tenderness, often in the calf or thigh.
• Warmth or redness in the affected area.
• Leg cramps, especially when standing or walking.

Pulmonary Embolism (PE)

A blood clot that makes its way to the lungs is called a pulmonary embolism. One of the symptoms could be sudden dyspnea.

• chest ache that gets worse when you breathe deeply.
• elevated heart rate.
• fainting or lightheadedness.
• coughing up blood.
• See a doctor right once if you encounter any of these symptoms.

Risk Factors for Blood Clots During Pregnancy

Some women are at higher risk of developing blood clots during pregnancy due to specific conditions or circumstances, including:

• Personal or family history of blood clots.
• Clotting disorders: Conditions like thrombophilia or antiphospholipid syndrome increase clotting risks.
• Obesity: Excess weight places additional pressure on blood vessels.
• Prolonged immobility: Sitting for long periods, such as during travel, can slow blood flow.
• Cesarean delivery: Surgical delivery increases the risk of clots compared to vaginal birth.
• Smoking: Tobacco use damages blood vessels, increasing clot risk.

Blood Clot Prevention During Pregnancy

It's crucial to avoid blood clots, particularly if you have risk factors. The following are some successful preventative techniques:

Remain Active

Healthy blood flow is promoted by regular movement. Prenatal yoga, swimming, and walking are some activities that help lower the chance of clots.

Put on compression stockings.

By enhancing circulation in the legs, compression stockings help keep blood from accumulating and clotting.

Drink plenty of water.

Water consumption lowers the risk of clots by maintaining a healthy blood viscosity.

Steer clear of extended sitting

Every hour, take a little walk to stretch your legs if you're traveling or spending a lot of time sitting down.

Observe Your Physician's Advice

Preventive measures like as low-dose aspirin or anticoagulant drugs (e.g., heparin) may be necessary for high-risk women.

Diagnosing Blood Clots in Pregnancy

If a blood clot is suspected, your doctor may use one or more of the following diagnostic tools:

• Doppler Ultrasound: The most common and non-invasive method to detect DVT in the legs.
• Blood Tests: A D-dimer test is used to assess clotting activity.
• Imaging Tests: In some cases, MRI or CT scans may be used to identify clots in the chest or other areas.

Treatment of Blood Clots During Pregnancy

Treatment focuses on preventing the clot from growing or travelling to the lungs while ensuring safety for both mother and baby. Common treatments include:

Anticoagulant Medications

• Low Molecular Weight Heparin (LMWH): This is the safest and most commonly prescribed blood thinner during pregnancy. It reduces clotting risk without crossing the placenta to the baby.
• Unfractionated Heparin: This may be used in certain situations that are particularly close to delivery.

Lifestyle Adjustments

• Stay active under your doctor’s guidance.
• Avoid sitting or lying down for long periods.

Close Monitoring

• Regular ultrasounds and blood tests help ensure that the clot is resolving and that no new clots are forming.

How to Manage Blood Clot During Delivery?

Managing blood clots continues during labour and delivery. Doctors will:

• Adjust anticoagulant medications as needed before delivery to reduce bleeding risks.
• Monitor for signs of clots post-delivery, as the risk remains high for several weeks after giving birth.

Pregnancy and Clotting Disorders

If you have a clotting disorder, pregnancy requires extra care. Women with conditions like thrombophilia or antiphospholipid syndrome may need:

• Regular checkups with a haematologist or maternal-fetal medicine specialist.
• Preventive anticoagulation therapy throughout pregnancy and postpartum.

Conclusion

Talk to your healthcare practitioner about preventive measures if you have a personal or family history of blood clots and you are pregnant or intend to become pregnant. Even before the baby is born, you can discuss those aspects with them, emphasizing how crucial it is to take proactive measures to ensure a safe and comfortable pregnancy for both of you.
