Varicose veins that develop during pregnancy often resolve without treatment in the first few months after delivery. Pregnancy increases pressure on veins in the pelvis and legs and also increases the volume of blood in your body, while reducing blood flow from the legs to the pelvis to help support the developing fetus. Changes in hormones during pregnancy can also play a role in the development of varicose veins and make the blood vessel walls more elastic.
