Your veins may become more prominent and visible on your skin when you are pregnant.

What is the reason of this?

Even if the excess circulating blood doesn't swell into your weaker leg veins and make them varicose, the increased amount of blood circulating in your body will expose your veins, especially in your breasts, as your body prepares itself to breastfeed. They can show themselves more boldly, especially on the skin.

Tips

These veins will return to their normal visibility after giving birth, sometimes with the exception of those in your breasts. These may not go away until you stop breastfeeding.
