Approximately 40% of pregnant women will get varicose veins. These bulging, bluish veins can be unpleasant to look at and may also result in some uncomfortable symptoms such as leg swelling or heaviness. The many pregnancy-related changes in the body places greater burden on veins, which are responsible for draining blood back toward the heart.
According to the American Pregnancy Association, pregnancy is associated with an increase in blood volume, a decrease in the rate at which blood moves from legs up to the pelvis, and surging hormones such as increased levels of progesterone which relaxes blood vessel walls.
Keep in mind that stretch marks are simply thin pink or purple lines on the surface of the skin. These are formed when the skin stretches and are not a sign of damaged veins!
