What causes Venous Disease and Varicose Veins? Normally, veins return the blood to the heart via uphill flow using Normal valves which act like one way double doors. If the veins walls are weak and the vein has weak or Abnormal valves, the vein permanently loose its ability to carry blood against gravity from the legs back up to the heart, and blood flows downhill toward the feet (reflux) instead of uphill towards the heart. With downhill flow (reflux) the blood pools in the legs stretching, dilating, enlarging and twisting the leg veins.

Which veins are unhealthy? In the leg there are two distinct vein systems. One is the superficial vein system which lies just beneath the skin but usually can’t be seen from the surface. Usually, problematic veins begin in the superficial system. The two main veins in the superficial system are the great saphenous vein and the small saphenous vein. Most of the problems from Venous Disease result from reflux in these saphenous veins. The second vein system in the leg is the important deep vein system. The deep vein system is located deep within the muscles. The deep veins carry most of the blood from the leg back to the heart.
