These compression stockings from Thuasne achieve a noticeable improvement of the blood circulation from the legs to the heart. They prevent major injuries, such as thrombosis or ulcers. This is achieved thanks to the slight pressure that the stockings exert on the legs. This type of stockings are usually used by people who have spider veins or varicose veins, although they are also recommended for use after venous surgery and to reduce leg pain in people who spend a long time standing without moving. If the doctor advises it, given the fluid retention that pregnant women usually have, its use is indicated, but always under medical prescription. However, for people who have disorders that may affect their arterial circulation, its use would not be recommended.
