How does graduated compression therapy help with management of venous problems? As a person walks, the contraction and relaxation of the calf muscles around the veins aid in moving blood toward the heart. The external graduated compression of compression socks and stockings acts as a layer of muscle by gently squeezing the stretched vein walls together, allowing the valves to close. The cavity of the vein is reduced, thereby restoring blood flow to a normal state and aiding overall circulation. To be most effective, the socks or stockings should be put on at the start of your day and removed before you got to bed. Some people have an inherited weakness of the vein walls or valves which creates additional challenges to venous return. Wearing compression stockings is vital for the prevention and treatment of varicose veins and other circulatory problems.
