Varicose Veins - Topic Overview
Varicose veins are
twisted, enlarged veins near the surface of the skin. They are most common in
the legs and ankles. They usually aren't serious, but they can sometimes lead
to other problems.
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.
veins often run in families. Aging also increases your risk.

Varicose veins are common and usually aren't a sign of a
serious problem. But in some cases, varicose veins can be a sign of a blockage

may need treatment for it.
Your doctor will
look at your legs and feet. Varicose veins are easy to see, especially when you
stand up. Your doctor will check your legs for tender areas, swelling, skin
color changes, sores, and other signs of skin breakdown.
You might need further tests if you plan to have treatment or if you
have signs of a deep vein problem.
