The reason is that multiple pregnancies is one of the risk factors that contribute to the presence of venous reflux. Other factors that contribute to these include age, gender, family history, heavy lifting, obesity, and prolonged standing. Using ultrasound to scan your legs, the vein specialist will determine if venous reflux is present. Consider a visit to a vein specialist for a full evaluation including the ultrasound scan.

During pregnancy your body goes through may changes, including an increase in blood volume and an increase in weight. Both of those can contribute to the formation of varicose veins. Once the veins become incompetent they stay that way, so as those conditions arise with recurrent pregnancies the veins could bulge more.

These changes are secondary to hormonal changes, and increased blood volume will increase pressure on the veins.

When pregnant, the increase in blood volume expands the size of the veins. Those that are insufficient will hurt more due to the pooling of blood that is caused by the valves not functioning properly and allowing for good circulation.

During pregnancy, there is a large hormonal shift. Also, there is up to a 30% increase in blood volume, and vein dilation is increased. Later in pregnancy, the enlarged uterus can press on the veins in the back of the pelvis when lying on your back causing some obstruction. Additionally, pressure in the leg veins is increased. All of these factors boost a woman's risk for having varicose veins.

Varicose veins following pregnancy are very common because pregnancy stretches the saphenous vein valves, which results in their leaking (refluxing). The hormones, especially progesterone, and fluid retention have the largest role. The increased venous pressure leads to the varicose veins.

Varicose veins and venous disease are hereditary for both men and women. For women, however, the condition can be exacerbated by pregnancy and its accompanying hormonal changes. That is why it is often advisable for female patients to wait until they are finished having children before considering any therapeutic vein work.

Varicose veins get worse with pregnancy because during the pregnant state, there is significant increase in estrogen, progesterone and relaxin. All of these hormones make it possible to carry a baby. Unfortunately, part of carrying a baby is allowing for an increase in blood flow, which is made possible by these hormones. Essentially, these hormones allow the veins/vessels to dilate to allow for increased flow. However, when veins dilate in this manner, even after the hormones decrease after delivery, the veins do not return to baseline. This is why abnormal veins just continue to get bigger and bigger with each subsequent pregnancy.

The hormone balance which supports pregnancy is stressful for veins and can cause damage which is additive with each successive pregnancy. Added to that is the extra pelvic pressure from the baby, which compresses veins and additional blood volume of pregnancy, making a "perfect storm" for people prone to varicose veins.

Varicose veins typically do appear or get worse, especially if you have a family history of them. The hormones of pregnancy dilate the veins to carry extra blood volume for the baby. We advise wearing measured and fitted compression stockings to slow down the development and make your legs more comfortable. No treatments should be done while pregnant or breast feeding. Wait until the hormones settle to normal as some veins may disappear.

Increased venous pressure and blood volume during pregnancy, as well as pregnancy hormones, weaken the connective tissue of the venous valves.

During pregnancy there is more blood in your body and, therefore, more blood refluxing through the dysfunctional veins (down the legs), which fills the varicose veins even more.

Varicose veins are due to malfunctioning (refluxing) of the valves, usually in the saphenous system. During pregnancy (and with each subsequent pregnancy), the valves continue to get stretched and further weaken. This is due to increased venous pressure in the veins, hormonal changes and increased volume changes during pregnancy.
