How Often Do Veins Fade After Pregnancy?

It is difficult to know exactly when or if veins will improve after pregnancy.  I would encourage you to wait at least 6 months after pregnancy to try sclerotherapy.

Great questions. Veins do resolve after pregnancy because there is a hormonally-dependent association between spider veins and estrogen/progesterone.  This does not mean that you will not have any veins on the legs postpartum.  You may continue to have some veins that have progressed beyond the ability of the body to resolve them.  I would wait about 6 months after pregnancy to begin sclerotherapy or EVLT. 

Many changes occur during pregnancy including hormonal and increased volume as well as the pressure of the developing fetus on the pelvic veins. This results in stretching of the venous valves leading to increased venous back pressure and resultant stretching (refluxing) of the venous valves leading to spider and possibly varicose veins. It takes anywhere from 3 to 6 months post delivery for these changes to resolve and longer if breastfeeding. In addition, the valves may permanently malfunction. Prior to any treatment for the veins you should have a full venous evaluation with a reflux ultrasound. Your veins may resolve spontaneously but, if not, then see a vein specialist.
