Pregnancy Complications
Blood Clotting Disorders
Conditions that affect blood clotting, increasing the risk of pregnancy complications including blood clots and placental problems.
What is Blood Clotting Disorders?
Blood clotting disorders (thrombophilias) are conditions where the blood has an increased tendency to form clots. They can be inherited (such as Factor V Leiden or antithrombin deficiency) or acquired (such as antiphospholipid syndrome). Pregnancy itself is a pro-thrombotic state, meaning it naturally increases clotting tendency — so women with underlying clotting disorders face compounded risk.
Why is it a Concern?
Clotting disorders in pregnancy increase the risk of deep vein thrombosis (DVT), pulmonary embolism, recurrent miscarriage, pre-eclampsia, placental abruption, fetal growth restriction, and stillbirth. Many of these complications relate to impaired blood flow through the placenta.
Signs & Symptoms
- Swelling, pain, or redness in one leg (possible DVT)
- Shortness of breath or chest pain (possible pulmonary embolism)
- History of unexplained pregnancy losses
- History of early-onset pre-eclampsia or growth restriction
- Family history of blood clots
- Often no symptoms until a complication occurs
How It is Monitored
Management may include blood-thinning medication (such as low-molecular-weight heparin), regular blood tests, and closer fetal monitoring. The specific approach depends on the type of clotting disorder, personal history, and pregnancy history. Delivery timing and postpartum anticoagulation are also carefully planned.
Why See an MFM Specialist?
MFM specialists are trained in the complex interaction between coagulation disorders and pregnancy, including when anticoagulation is warranted, how to monitor its effectiveness, and how to manage delivery safely in anticoagulated patients.

Book ConsultationFrequently Asked Questions
Should I be tested for clotting disorders?
Testing may be recommended if you have a history of unexplained pregnancy loss, early pre-eclampsia, growth restriction, blood clots, or a strong family history of thrombosis.
Will I need blood thinners throughout pregnancy?
This depends on your specific condition and history. Some women require daily injections throughout pregnancy and the postpartum period, while others may need them only during specific periods.
Can I have a normal delivery?
Most women with clotting disorders can deliver vaginally. Your anticoagulation medication will be adjusted around delivery to minimise bleeding risk.
Will I need injections after delivery?
Many women with clotting disorders need anticoagulation for a period after delivery, as the postpartum period carries the highest clot risk. Duration is individualised.
Can I take aspirin with a clotting disorder?
Low-dose aspirin is often recommended from early pregnancy for specific conditions, particularly antiphospholipid syndrome. Dr. Kartik will advise based on your diagnosis.
