During pregnancy, vulvar varicosities can occur for many reasons. Increased weight of the enlarged uterus sometimes creates pressure on veins in the pelvic area and interferes with the flow of blood returning from the legs. Naturally higher levels of estrogen promote growth, while increased progesterone tends to relax the smooth muscles of the vein walls. The relaxed veins can become distended and "pop out" as vulvar varicosities. Wearing the V2 supporter before rising in the morning, helps prevent excessive swelling of the vulvar veins.
