What Are Varicose Veins?
Varicose (VAR-i-kos) veins are swollen, twisted
veins that you can see just under the surface of the skin. These veins usually
occur in the legs. However, they also can form in other parts of your body.
Varicose veins are a common condition. They usually
cause few signs or symptoms. In some cases, varicose veins may cause
complications, such as mild to moderate pain, blood clots, or skin ulcers.
Overview
Veins are blood vessels that carry blood from your
body's tissues to your heart. The heart pumps the blood to your lungs to pick
up oxygen. The oxygen-rich blood is then pumped out to your body through your
arteries.
From your arteries, the blood flows through tiny
blood vessels called capillaries, where it gives up its oxygen to the body's
tissues. Your blood then returns to your heart through your veins to pick up
more oxygen.
Veins have one-way valves that help keep blood
flowing toward your heart. If your valves are weak or damaged, blood can back
up and pool in your veins. This causes the veins to swell and can lead to
varicose veins.
A number of factors may increase your risk for
varicose veins. These include family history, age, gender, pregnancy,
overweight
or obesity, and lack of movement.
Varicose veins are treated with lifestyle changes
and medical procedures. The goals of treatment are to relieve symptoms, prevent
complications, and improve appearance.
Outlook
Varicose veins usually don't cause medical problems.
If your varicose veins cause few signs and symptoms, your doctor may suggest
simply making lifestyle changes.
In some cases, varicose veins can cause
complications, such as pain, blood clots, or skin ulcers. If your condition is
more severe, your doctor may recommend one or more medical procedures. Some
people choose to have these procedures to improve the appearance of their
varicose veins or to relieve pain.
A number of treatments are available for varicose
veins that are quick and easy and don't require a long recovery time.
