A number of studies have shown that hormonal levels influence the development of varicose veins. Nearly 70% of women develop varicose and spider veins during pregnancy. The appearance of vein disorders are due to changes in hormonal levels, as well as an increase in blood volume that occurs while pregnant. In some cases, varicose veins disappear approximately 5-7 weeks after childbirth. However, it’s highly recommended for women to wear compression stockings during pregnancy to encourage healthy blood flow.
Varicose veins can also develop for those taking birth control and hormone replacement therapy. Research suggests this may be because female hormones tend to relax the walls of veins, making the valves more prone to leaking. Remember to discuss these factors with Dr. Leary if you have a family history of vein disorders.
