Vein Disorders (Varicose and Spider Veins)


Varicose veins are enlarged veins that are swollen and raised above the surface of the skin. They can be dark purple or blue, and look twisted and bulging. Varicose veins are commonly found on the backs of the calves or on the inside of the leg. They develop when valves in the veins that allow blood to flow toward the heart stop working properly. As a result, blood pools in the veins and causes them to get larger.

Varicose veins affect 1 out of 2 people over age 50. They are more common in women than men. Hemorrhoids are a type of varicose vein. Spider veins are like varicose veins, but they are smaller.

Exercising, losing weight, elevating your legs when resting and not crossing them when sitting can help keep varicose veins from getting worse. Wearing loose clothing and avoiding long periods of standing can also help. If varicose veins are painful or you don't like the way they look, your doctor may recommend procedures to remove them.
