Understanding Vein Disease

To better understand vein disease (Venous Insufficiency), you should know the purpose and function of the veins in your body. Healthy veins pump blood back to the heart using one-way valves, which stop blood from moving in the opposite direction. Sometimes these valves weaken, allowing blood to flow backward and pool inside the veins. This backward flow, or reflux, causes a high pressure build-up leading to Venous Insufficiency.
