Varicose Veins An Overview

In healthy veins, valves allow blood to flow only one way. When these valves fail-allowing blood to back up and pool inside the vein, making it swell-the result is varicose veins.

They can be unsightly and painful, but they’re usually not dangerous.
Varicose veins can appear anywhere, but they show up mostly on the legs, sometimes surrounded by patches of thin, red capillaries or green veins – known as “spiders.”

This condition tends to run in families. Women, especially those of German or Irish descent, are twice as likely as men to develop them. Anything that puts added pressure on the legs, such as standing for long periods, pregnancy, and obesity, can cause varicose veins.

Varicose veins can be removed surgically or treated with medications.
