A. thrombophlebitis
B. pregnancy induced hypertension
C. pressure on blood vessels from the enlarging uterus

Pressure of the growing uterus on blood vessels results in an increased risk for venous stasis in the lower
extremities. Subsequently, edema and varicose vein formation may occur. Thrombophlebitis is an
inflammation of the veins due to thrombus formation. Pregnancy-induced hypertension is not associated
with these symptoms. Gravity plays only a minor role with these symptoms.
