Varicose veins

Definition:
Varicose veins are gnarled, enlarged veins. Any vein may become varicose, but the veins most commonly affected are those in your legs and feet. That’s because standing and walking upright increases the pressure in the veins of your lower body.

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.

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. Varicose veins may also signal a higher risk of other circulatory problems. Treatment may involve self-care measures or procedures by your doctor to close or remove veins.

Symptoms:
Varicose veins usually don’t cause any pain. Signs you may have varicose veins include:

*Veins that are dark purple or blue in color
*Veins that appear twisted and bulging; often like cords on your legs
*Varicose veins may also form in other places on your legs, from your groin to your ankle.

When painful signs and symptoms occur, they may include:

*An achy or heavy feeling in your legs
*Burning, throbbing, muscle cramping and swelling in your lower legs
*Worsened pain after sitting or standing for a long time
*Itching around one or more of your veins
Skin ulcers near your ankle, which can mean you have a severe form of vascular disease that requires medical attention . 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. They occur on the legs, but can also be found on the face. Spider veins vary in size and often look like a spider’s web.

When to call health care provider
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.


Causes:

Arteries carry blood from your heart to the rest of your tissues. 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.

Causes of varicose veins can include:

*Age. As you get older, your veins can lose elasticity causing them to stretch. The valves in your veins may become weak, allowing blood that should be moving toward your heart to flow backward. Blood pools in your veins, and your veins enlarge and become varicose. The veins appear blue because they contain deoxygenated blood, which is in the process of being recirculated through the lungs.

*Pregnancy. Some pregnant women develop varicose veins. Pregnancy increases the volume of blood in your body, but decreases the flow of blood from your legs to your pelvis. This circulatory change is designed to support the growing fetus, but it can produce an unfortunate side effect — enlarged veins in your legs. Varicose veins may surface for the first time or may worsen during late pregnancy, when your uterus exerts greater pressure on the veins in your legs. Changes in your hormones during pregnancy also may play a role. Varicose veins that develop during pregnancy generally improve without medical treatment within three months after delivery.

Risk factors:
These factors increase your risk of developing varicose veins:

*Your age. Varicose veins occur most often in people ages 30 to 70, with your risk increasing as you 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 blood to flow back into your veins where it collects instead of flowing up to your heart.

*Your sex. Women are more likely to develop the condition. Hormonal changes during pregnancy, premenstruation or menopause may be a factor. Female hormones tend to relax vein walls. Taking hormone replacement therapy or birth control pills may increase your risk of varicose veins.

*Genetics. 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 for long periods of time. Your blood doesn’t flow as well if you’re in the same
position for long periods.

Complications:-
Complications of varicose veins, although rare, can include:
Ulcers. Extremely painful ulcers may form on the skin near varicose veins, particularly near the ankles. Ulcers are caused by long-term fluid buildup in these tissues, caused by increased pressure of blood within affected veins. A brown colored 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 swell considerably. Any sudden leg swelling warrants urgent medical attention because it may indicate a blood clot — a condition known medically as
thrombophlebitis.
