Varicose Veins

Back

Varicose veins are veins that have become enlarged and twisted. The term commonly refers to the veins on the leg, although varicose veins can occur elsewhere. Veins have Pairs of leaflet valves to prevent blood from flowing backwards (retrograde flow or venous reflux).

SYMPTOMS

For many people, there are no symptoms and varicose veins are simply a cosmetic concern. In some cases, they cause aching pain and discomfort or signal an underlying circulatory problem.

CAUSES

Varicose veins are caused by weakened valves and veins in your legs. Normally, one-way valves in your veins keep blood flowing from your legs up toward your heart. When these valves do not work as they should, blood collects in your legs, and pressure builds up. The veins become weak, large, and twisted.
