Varicose veins


Varicose veins

Normally, veins return blood from the rest of your body to your heart, so the blood can be recirculated. To return blood to your heart, the veins in your legs must work against gravity. Varicose veins may be caused by weakened valves (incompetent valves) within the veins that allow blood to pool in your veins instead of traveling to your heart.

Spider veins

Spider veins appear as thin, red lines or as weblike networks of blood vessels on the surface of the skin. Spider veins, a mild form of varicose veins, typically appear on the legs and feet.

Varicose veins are twisted, enlarged veins. Any superficial vein may become varicosed, but the veins most commonly affected are those in your legs. That's because standing and walking upright increases the pressure in the veins of your lower body.

For many people, varicose veins and spider veins — a common, mild variation of varicose veins — are simply a cosmetic concern. For other people, varicose veins can cause aching pain and discomfort. Sometimes varicose veins lead to more-serious problems.

Treatment may involve self-care measures or procedures by your doctor to close or remove veins.

Varicose veins may not cause any pain. Signs you may have varicose veins include: Veins that are dark purple or blue in color

When painful signs and symptoms occur, they may include: An achy or heavy feeling in your legs

Worsened pain after sitting or standing for a long time

Itching around one or more of your veins

Spider veins are similar to varicose veins, but they're smaller. Spider veins are found closer to the skin's surface and are often red or blue.

Spider veins occur on the legs, but can also be found on the face. They vary in size and often look like a spider's web.

When to see a doctor

Self-care — such as exercise, elevating your legs or wearing compression stockings — can help you ease the pain of varicose veins and may prevent them from getting worse. But if you're concerned about how your veins look and feel and self-care measures haven't stopped your condition from getting worse, see your doctor.

Weak or damaged valves can lead to varicose veins. Arteries carry blood from your heart to the rest of your tissues, and veins return blood from the rest of your body to your heart, so the blood can be recirculated. To return blood to your heart, the veins in your legs must work against gravity.

Muscle contractions in your lower legs act as pumps, and elastic vein walls help blood return to your heart. Tiny valves in your veins open as blood flows toward your heart then close to stop blood from flowing backward. If these valves are weak or damaged, blood can flow backward and pool in the vein, causing the veins to stretch or twist.

Risk factors

These factors increase your risk of developing varicose veins: Age. The risk of varicose veins increases with age. Aging causes wear and tear on the valves in your veins that help regulate blood flow. Eventually, that wear causes the valves to allow some blood to flow back into your veins where it collects instead of flowing up to your heart.

Sex. Women are more likely to develop the condition. Hormonal changes before your period or during pregnancy or menopause might be a factor because female hormones tend to relax vein walls. Hormone treatments, such as birth control pills, might increase your risk of varicose veins.

Pregnancy. During pregnancy, the volume of blood in your body increases. This change supports the growing fetus, but also can produce an unfortunate side effect — enlarged veins in your legs. Hormonal changes during pregnancy may also play a role.

Family history. If other family members had varicose veins, there's a greater chance you will too.

Obesity. Being overweight puts added pressure on your veins.

Standing or sitting for long periods of time. Your blood doesn't flow as well if you're in the same position for long periods.

Complications of varicose veins, although rare, can include: Ulcers. Painful ulcers may form on the skin near varicose veins, particularly near the ankles. A discolored spot on the skin usually begins before an ulcer forms. See your doctor immediately if you suspect you've developed an ulcer.

Blood clots. Occasionally, veins deep within the legs become enlarged. In such cases, the affected leg may become painful and swell. Any persistent leg pain or swelling warrants medical attention because it may indicate a blood clot — a condition known medically as thrombophlebitis.

Bleeding. Occasionally, veins very close to the skin may burst. This usually causes only minor bleeding. But any bleeding requires medical attention.

There's no way to completely prevent varicose veins. But improving your circulation and muscle tone may reduce your risk of developing varicose veins or getting additional ones.
