Causes of Vein Disease

Veins Causes – A common problem all over the world, vein disease affects over 2.5 million people in the United States alone. Vein disease is largely genetic, passed down from parents to offspring. Healthy veins transport blood efficiently back to the heart after the nutrients that were in the bloodstream have been used up by the body. The blood travels in a one-way stream, in part, by a series of valves that open to let blood in, but close to keep blood from going backwards.

In diseased veins, these valves are damaged and unable to function properly, so the blood that was supposed to go to heart now creates pressure in the veins by trying to flow backwards. This blood pools in the leg veins and leads to varicose veins.

Vein disorders can also arise when there is an obstruction in the vein, as in the instance of clotting or deep vein thrombosis. Additionally, chronic venous injury or compression can narrow the passage for the flow of blood, leading to tension in the veins of the lower leg and ankle.
