Varicose veins are bumpy blue veins that usually appear on the legs during pregnancy. There are several reasons for this. The amount of blood in the body becomes greater and this must be pumped around the body. Due to the changing hormone level, the vein walls can weaken. Also, a growing uterus can block the flow of blood from the legs to the heart. This results in swollen veins in the legs and anus (hemorrhoids).
Varicose veins are more common in women who have previously had children. The more pregnancies you have, the greater your chances of getting them. They look like swollen veins. They can be dark blue or purple in color.
