Causes    TOP

Veins have one way valves to channel blood back to the heart. Damage to the valves causes blood to pool in the veins. This causes them to get bigger. They’re also easier to see under the skin.

Risk Factors    TOP

Varicose veins are more common in women. Your chances are also higher if you:

  • Are older
  • A family history
  • Go through hormonal changes
  • Put pressure on the veins of the pelvis—can happen with pregnancy
  • Are overweight
  • Work in a job that where you sit or stand for long periods of time
  • Smoke

Symptoms    TOP

Common problems include:

  • Enlarged, twisted, and swollen veins that you can see
  • Achy, tired, or a heavy feeling in the legs
  • Leg cramps
  • Burning or throbbing pain in the legs
  • Itching
  • Swollen legs

Skin changes may result in:

  • Rashes
  • Discoloration
  • Sores that are hard to heal

Diagnosis    TOP

The doctor will ask about your symptoms and health history. Your answers and a physical exam may point to varicose veins. In some cases, a Doppler ultrasound may be done.

Treatment    TOP

Care may involve:

Lifestyle Changes

To start out, your doctor may advise:

  • Not standing or sitting for long periods of time.
  • Resting with your legs raised above your heart.
  • Moving your legs around when standing or sitting for long periods of time.
  • Wearing compression stockings. They may help improve blood flow in your legs.

Procedures

Procedures are done if other care methods fail to work:

  • Laser or light source energy to seal, collapse, and dissolve varicose veins
  • Sclerotherapy—a chemical is injected to shrink the veins
  • Radiofrequency ablation—collapses and seals varicose veins
  • Endovenous mechanochemical ablation—closing varicose veins with a rotating wire and chemical agent
  • Adhesive sealing—sealing veins close to the skin using an adhesive agent
  • Surgery—banding and removing affected veins

Prevention    TOP

To lower your chances of varicose veins.

  • Lose excess weight if you need to.
  • Get regular physical activity.
  • Don’t stand or sit for long periods of time. Move around when you can.
