If you are pregnant, you are at greater risk of developing a blood clot because blood clots more easily during pregnancy.
Blood clots in pregnant women tend to form in the deep veins of the legs or in the pelvic area. This condition is known as deep-vein thrombosis (DVT). Pulmonary embolism (PE) is a life-threatening event that occurs when a clot from elsewhere in the body breaks off and travels to the lungs.
DVT and PE, collectively known as venous thromboembolism, are highly preventable (see prevention tips below). The U.S. Surgeon General has issued a Call to Action on DVT and PE to raise public awareness of these blood conditions and increase research on the causes, prevention, and treatment.
Blood clots are also potentially dangerous to your baby. Blood clots can form inside the placenta, cutting off blood flow and harming your baby.
Am I at Risk?
Risk of developing a blood clot during pregnancy is increased by the following:
- Prolonged bed rest
- Prolonged inactivity (long trips by plane or car)
- Surgical deliveries
- Genetic predispositions to blood clots
How are Blood Clots in Pregnant Women Treated?
Typically, women who develop blood clots during pregnancy are given an anticoagulant, a medicine that prevents the blood from clotting.
Are Blood Clots Preventable?
There are a few things that you can do to prevent blood clots during pregnancy:
- Be aware of risk factors.
- Know your family history.
- Make sure your doctor knows about any history of blood clots or blood clotting disorders in your family.
- Remain active, with your doctor’s approval.
- Be aware of the signs and symptoms of a blood clot. Visit your doctor immediately if you think you have one.
If you are pregnant and have concerns about blood clots, talk with your doctor about your risks and prevention. Depending on your condition, your OB-GYN may refer you to a hematologist, a doctor who specializes in treating blood conditions.

Where Can I Find More Information?
If you find that you are interested in learning more about blood diseases and disorders, here are a few other resources that may be of some help:
Articles From Hematology, the ASH Education Program
The American Society of Hematology (ASH) Education, updated yearly by experts in the field, is a collection of articles about the current treatment options available to patients. The articles are categorized here by disease type. If you are interested in learning more about a particular blood disease, we encourage you to share and discuss these articles with your doctor.
Results of Clinical Studies Published in Blood
Search Blood, the official journal of ASH, for the results of the latest blood research. While recent articles generally require a subscriber login, patients interested in viewing an access-controlled article in Blood may obtain a copy by e-mailing a request to the Blood Publishing Office.
This section includes a list of Web links to patient groups and other organizations that provide information.
