Do you have a question?
When the blood in the lower body has trouble returning to regular circulation, varicose veins can develop. These bulging veins have weakened walls and have lost the integrity of the valves that usually keep blood from pooling. Varicose veins may show on the surface or may hide deeper inside. A complete examination will reveal any unseen varicose veins.
What Causes Varicose Veins During Pregnancy?
Throughout pregnancy, a woman’s blood volume increases, putting extra pressure on the veins. Additionally, pregnancy-related hormonal changes and fluctuations can also lead to the development of varicose veins, mostly in the legs, but sometimes, also, in the buttocks or vaginal area. Also, the growing weight of the uterus compresses the pelvic veins and the vena cava (the vein that carries blood from the legs and feet to the heart), further contributing to the development of varicose veins.
