It’s estimated that 70% to 80% of pregnant women develop varicose veins during the first trimester. Pregnancy causes an increase in blood volume; however, it’s the hormonal changes that cause the veins to enlarge. Elevated levels of progesterone, which the body produces to stabilize the uterus, allow the veins to dilate. Later, the uterus enlarges and causes increased pressure on the veins in the pelvic area. While varicose veins often disappear after delivery, the venous valves are damaged. When varicose veins are still visible after three months, it’s time contact a vein specialist. It’s important you look good, feel good, and remain healthy—particularly after pregnancy.
