Pregnancy: Varicose Veins

Topic Overview

Varicose veins are enlarged, swollen veins that are
caused by faulty valves in the veins or weak vein walls. They are common during
pregnancy, particularly in women with a family history of the problem.

Varicose
veins typically develop on the legs but can also affect the
vulva. Though varicose veins are often only a cosmetic
concern, they can become painful. In severe cases, they can bleed.

During pregnancy, the growing uterus puts more pressure on the veins
that return blood from the legs, and it becomes harder for blood to
leave the legs. (The extra weight of multiple fetuses puts an even greater
burden on the deep veins in the legs.) This can lead to pooled blood that
causes one or more veins to swell.

If you or other women in your family have had varicose veins, use
preventive and treatment measures that are safe during pregnancy.

Avoid prolonged standing and
sitting.

Lie on your side as much as possible. This takes the
pressure off your leg veins, allowing normal blood flow.
