Also known as Vulvar Varicosities these veins usually appear in pregnancy and is estimated that it effects 5-10% of pregnant women. These veins often ease after childbirth but do not ever completely go away and multiple pregnancies worsen the condition.
These veins are caused by damage to the vein values or walls in this area. After the damage occurs the blood is not able to flow back to the heart efficiently and begins to pool. This leads to enlarged veins known as varicose veins. During pregnancy increased blood flow and pressure on the genital region can lead to these vaginal & vulvar varicose veins.
In some woman the varicose veins stay in the vulva region. In many they often lead to varicose veins in the upper thigh and inner part of the leg.
