Varicose Veins…They’re an Inside Job

October 7, 2012 By Staff

Compared with other veins in the body, leg veins have the toughest job. They have to work against gravity to get blood back up to the heart. If you have weak veins or you don’t move around enough, blood can start pooling in your legs.

Sometimes the pressure from the pooled blood is stronger than the tiny valves can handle. If a valve buckles and gives out, blood starts flowing backward, down towards the ankles. The increased pressure from this extra volume of blood causes more valves to fail and the thin vein walls to stretch. As veins weaken they begin to swell and “pop-out”. And those ugly varicose veins make their debut.
