Why does Pregnancy increase the risk of thrombosis?

This is because a woman's body suffers from various changes, including changes in blood composition:

  • Incease in the synthesis of coagulation factors
  • Increased resistance of activated protein C
  • Decrease of natural anticoagulants such as protein S
  • More venous stasis

All these variations lead to the production of thrombin, which can trigger a thrombosis in the vessels of the placenta and halt fetal development.
