Why Does Blood Clotting Increases During Pregnancy?

During pregnancy the blood clotting capacity of the body increases to a certain extent. It generally occurs as a precautionary measure to prevent excessive bleeding during childbirth. The amount of protein that is responsible for clotting of blood increases in comparison to the protein that prevents clotting. There are several other causes that contribute to Deep Vein Thrombosis such as enlargement of the uterus which tends to create more pressure on the veins thus resulting in a blood clot.
