Hypercoagulability
Extracted from the Wikipedia article Thrombophilia.
Acquired
Pregnancy is associated with an increased risk of thrombosis of 2- to 7-fold. This probably results from a physiological hypercoagulability in pregnancy that protects against postpartum hemorrhage. This hypercoagulability in turn is likely related to the high levels of estradiol and progesterone that occur during pregnancy.
