What You Should Know About Deep Vein Thrombus (DVT) in Pregnancy

DVT treatment

Women face some unique challenges during pregnancy. From morning sickness to backaches, pregnancy comes with its share of discomfort. But did you know there’s another less talked about yet equally important concern?

Deep Vein Thrombosis, or DVT, is a complication pregnant women can encounter. If you’re a current or potential mum-to-be or caring for someone who is, this article is tailored just for you.

In this article, we’ll explore what DVT is, how to recognise its symptoms, understand the risks involved, prevention and most importantly, discover DVT treatment. Let’s explore what you need to know about DVT in pregnancy to keep you and your baby safe.

Symptoms of DVT

DVT, or deep vein thrombosis, often presents a set of common signs. Before we dive into DVT treatment, it’s important to know the common factors. The most conspicuous signs are the swelling and severe leg pain or pronounced tenderness.

But there’s more to be aware of. Other potential symptoms of DVT include:

  • Leg pain that intensifies when standing or moving.
  • An increase in leg pain when bending the foot upwards towards the knee.
  • The skin in the affected area feels warmer than usual.
  • Noticeably enlarged veins.
  • Discoloration or redness appears on the skin behind the knee, usually below it.
  • A bluish tinge in the toes.
  • Swelling, ranging from slight to severe.

Intriguingly, approximately 50% of individuals with acute DVT might not display any symptoms.

This seems more common among postoperative patients, especially those undergoing orthopedic surgery.

The odds seem low regarding the possibility of asymptomatic DVT occurring before or after pregnancy.

However, individuals with multiple risk factors should consider thorough DVT screening with a vascular surgeon to stay safe, particularly after cesarean delivery.

Causes of DVT in Pregnancy

Several factors contribute to an increased risk of Deep Vein Thrombosis (DVT) during pregnancy. These include

  • Physiological Changes: Pregnancy brings about significant physiological changes, including increased pressure on pelvic veins due to the growing baby.
  • Altered Clotting Factors: Changes in blood clotting factors start early in pregnancy and persist for up to six weeks postpartum, raising the risk of DVT.
  • Hormonal Influence: Elevated estrogen levels during pregnancy increase the likelihood of blood clot formation, similar to the risk women face on estrogen-containing birth control pills.
  • Genetic Clotting Disorders: Individuals with genetic clotting disorders, known as thrombophilias, are at an even higher risk of developing DVT during pregnancy.

Understanding these factors is crucial for identifying and receiving DVT treatment in expectant mothers.

Preventing and Treating DVT

Preventing deep vein thrombosis (DVT) during pregnancy is important for both the mother and baby. Here are some strategies to help prevent DVT during pregnancy:

– Consult your healthcare provider

Discuss your risk factors and DVT treatment with your vascular surgeon. They can provide personalised recommendations based on your medical history and risk factors.

– Maintain a healthy lifestyle

Eat a balanced diet, exercise regularly, and maintain a healthy weight. Staying active can improve blood circulation. Drink plenty of water to help prevent blood from thickening.

– Avoid long periods of immobility

If you have to sit or stand for long periods, try to take breaks to move around and stretch your legs. This is particularly important if you have a desk job or travel frequently. Elevating your legs when resting can help improve circulation.

– Compression stockings

Your vascular surgeon may recommend wearing compression stockings, which can help improve leg blood flow.

– Medications

Sometimes, your vascular surgeon may prescribe blood-thinning medications to reduce the risk of clot formation. However, this should only be done under medical supervision.

– Avoid smoking and alcohol

Both smoking and alcohol consumption can increase the risk of DVT and harm your baby, so it’s best to avoid them, especially during pregnancy.

– Know the symptoms

Familiarise yourself with the symptoms of DVT, such as leg pain, swelling, redness, or warmth. If you experience any of these symptoms, contact your vascular surgeon immediately. Follow your doctor’s recommendations closely if you have any underlying medical conditions or risk factors.

Understand that every pregnancy is unique, and your healthcare provider will tailor their advice to your specific situation. It’s crucial to have open communication with your vascular surgeon to ensure DVT treatment for a safe and healthy pregnancy.


Deep Vein Thrombosis (DVT) is a serious concern during pregnancy. Recognising symptoms, understanding risk factors, and preventive measures are crucial. Pregnancy-related factors increase DVT risk. Consult with healthcare providers, maintain a healthy lifestyle, wear compression stockings when necessary, and seek help for DVT treatment promptly. Vascular surgeons play a key role in assessing and treating DVT risk. Personalised care is vital for a safe pregnancy.
