Varicose veins appear in the legs during pregnancy because the enlarged uterus compresses the iliac veins, which leads to an increase in the pressure in the deep veins, and the high pressure in the deep veins is transmitted to the superficial venous system, which causes the varicose veins that can be seen on the surface of the body, which is its root cause. The treatment is mainly conservative, by means of pressure therapy, which allows the blood from the superficial veins to enter the deep veins, increasing the pressure in the deep veins and at the same time promoting the venous reflux, because during pregnancy both the woman and the fetus are very sensitive to the drugs. Drug treatment for varicose veins is not suitable for pregnant women and may lead to fetal malformations. Therefore, conservative treatment by wearing elastic stockings or elastic bandages can effectively restrain the progression of varicose veins and also ensure the safety of the fetus. At the same time, the habits of life should also be changed, not to stand and sit for a long time, because when you stand and sit for a long time there will be an increase in the pressure of the leg veins, so when you sit or remain in a standing position for a long time, you should move properly at intervals to increase blood circulation.
