What Causes Varicose Veins? Symptoms
Varicose veins are widened, bulging, and twisted veins under the skin. There are tiny one-way valves inside the veins open to let the blood through and close to prevent flowing backwards. At times the walls of the veins lose their elasticity, which in turn causes the valves to weaken. This can cause the blood to flow backwards. Thus, blood collects in veins and become swollen and enlarged.
Varicose veins mostly affect the veins in legs. There are two main vein systems in the legs.
- Deep veins – It allows a high volume and pressure of blood to flow through the
Veins. And so, detailed examination of deep veins are done in
Ultrasound scans to investigate varicose veins.
- Superficial Veins – Blood flows from the superficial veins through the perforator veins to
the deep veins.
