For a lot of women, varicose veins appear for the first time during their pregnancy. Few of the women might notice that these veins become more prominent if they already had them. Pregnancy doesn’t cause the varicose veins, it just causes the underlying problem to aggravate hence, there is manifestation of the disease. The women who develop varicose veins during their pregnancy have an underlying genetic problem with their valves. The increased abdominal and pelvic pressure due to the growing baby on the valves in the pelvis puts pressure on the veins in the legs which combined with the valve failure brings out the varicose veins. Few women may also find development of varicose veins on the vulva. This is quite a common problem during pregnancy.
