Varicose veins are enlarged, swollen veins near the surface of the skin. They're caused by faulty valves in the veins or weak vein walls. Varicose veins usually occur on the legs, but they can also affect the vulva. They are common during pregnancy.
When the growing uterus puts pressure on the veins that return blood from the legs, it becomes harder for blood to leave the legs. This can lead to pooled blood that causes one or more veins to swell. The extra weight of multiple fetuses puts an even greater burden on the deep veins in the legs.
People who have a family history of varicose veins are most likely to get them.
Varicose veins are common during pregnancy. To lower your risk, use measures that are safe during pregnancy.
Prolonged sitting and standing puts added stress on your veins.
This takes the pressure off your leg veins, allowing normal blood flow.
Gravity helps with blood return from your legs to your heart.
Compression stockings are designed to help keep blood from pooling in your legs.
Being active helps improve blood flow in your legs.
