It's an unfortunate fact that spider veins and varicose veins are more likely to develop during pregnancy. We'll explain why and what you can do to treat them.
The bad news about spider veins and varicose veins is that if your mother had them when she had you, you're likely to get them as well. Spider veins are purple, small, and look just like what they sound like. Varicose veins are bluer, larger, and more ropey. Why do they happen? During pregnancy, you have a lot more blood floating around your body than usual, and this puts pressure on your veins. Also the more pregnant you get, the more pressure your uterus is putting on your veins in your pelvis. And what that does is it also puts pressure on the veins on your legs. Eventually the veins just can't keep up with all that blood pumping back to the heart, and so new veins are made and existing veins get bigger. The good news is there are things you can do to prevent that. Try to get off your feet as much as you can especially in the third trimester, even if that means putting your legs up at work or watching TV with your legs elevated on a pillow. If it's not too hot where you live, I recommend using support knee highs or stockings and Sigvaris and Jobst are 2 brands that you can look for. Also know that if you do get these veins, there are a lot of really good treatments now. Sclerotherapy is when a special solution is injected into the veins, which makes them collapse, and several lasers are very good at getting rid of the smaller spider veins. Even better news, many of these veins are gonna go away 3 to 4 months after you deliver and you may not need treatment at all.
