The heart pumps blood filled with oxygen and nutrients to the whole body. Arteries carry blood from the heart towards the body parts. Veins carry oxygen-poor blood from the body back to the heart.

The squeezing of leg muscles pumps blood back to the heart from the lower body. Veins have valves that act as one-way flaps. These valves prevent the blood from flowing backwards as it moves up the legs. If the one-way valves become weak, blood can leak back into the vein and collect there. This problem is called venous insufficiency. Pooled blood enlarges the vein and it becomes varicose. Spider veins can also be caused by the backup of blood. Hormone changes, inherited factors, and exposure to the sun can also cause spider veins.

Varicose veins are caused when the small valves in them which prevent gravity from making the blood pool in your legs start to become inefficient. This causes some backflow of the blood causing it to inflate the veins.

Small amounts of varicosity are not serious--just unsightly, but a lot of varicosity can cause health problems.

It can be surgically repaired by stripping the veins out and sometimes by taking veins from elsewhere to replace them...
