Maintaining proper blood flow from the legs to the heart is one of the body's biggest challenges. With the legs below and farthest from the heart, an intricate set of one-way valves within the vein system helps the blood move in "steps" up the legs. After years of use, these valves may eventually malfunction. Injury, disease, weight, age, heredity, extended periods of standing and pregnancy can also contribute to vein insufficiency.
Physicians recommend graduated compression therapy for vein insufficiency. Graduated compression hosiery helps provide this therapy by compressing surface veins and forcing more blood into the deep vein system. This increases blood flow velocity and helps to relieve the symptoms of vein insufficiency.
