About Venous Disease
Vein disease affects more than 25 million Americans today. It is caused when the walls of the veins become weak or damaged. In a healthy individual, veins have one-way valves that work within the circulatory system to pump blood back up to the heart.In a normal circulatory system, the blood flows to and from the heart by way of arteries and veins. Arteries take oxygen rich blood away from the heart and veins return blood to the heart.
