Pregnancy and the Risk for Blood Clots
Pregnancy and childbirth can increase the risk for blood clots.
A woman is at increased risk up to 3 months after her baby is born.
Risks for blood clots during pregnancy, childbirth, and up to 3 months after the baby is born include:
Prolonged immobility due to bed rest during pregnancy or recovery after delivery
A previous blood clot, a family history of clots, or a genetic blood clotting disorder
Delivery by C-section
Pregnancy at age 35 or older
Overweight or obesity
Certain pregnancy complications, such as pregnancy with multiple babies or the use of fertility treatments involving hormones
