Varicose veins arise because of peripheral venous stasis in your lower extremities secondary to poor blood return to your heart. In other words, blood pools in your leg veins. The best treatment is often lifestyle changes starting with weight reduction. Secondly, compression stockings can be worn to prevent vein dilation. And finally, frequent leg elevation will prevent the blood from pooling in your leg veins. If these conservative lifestyle changes don’t work, surgery can also be performed.
