Understanding varicose veins and venous insufficiency

Varicose veins, those large, serpentine capillaries just under the skin on the calves and thighs, are the most common circulatory problem of the lower extremities. It is estimated that 40 percent of women in the United States have them. More than 20 million men and women are significantly affected by this condition. In most cases, those with varicose veins also have another circulatory condition known as chronic venous insufficiency. Caused by inadequate blood flow through the blood vessels inside the legs, chronic venous insufficiency is most often a complication of a thrombus formation (blood clot) in the deep veins. Fortunately, a lot can be done to relieve the symptoms of these disorders and prevent them from occurring in the first place.

What are the causes of vein problems?

​

If your veins have trouble carrying blood from your feet back to your heart you have a vein problem. The effect of your venous condition will usually be felt in your legs. Vein problems may be cosmetic (bulging or varicose), or they may cause your legs to ache , burn, or swell. Some vein problems can cause blood clots or damage skin tissue (ulcers). But be reassured that no matter how serious your vein problem is, treatment can help control your symptoms.

What are your risk factors?​
 

Both men and women can be affected by vein problems. Your general health condition and life style habits may increase your chances of developing a problem. Heredity, surgery, injury and pregnancy are also risk factors you can't necessarily control. But you can control other risks, such as being overweight, not exercising, and standing for long periods of time.
  • Heredity may cause weak veins and is the top risk factor for vein problems.
  • Surgery, especially near the hips and pelvis may make some vein problems more likely.
  • Standing for long periods makes your veins work against gravity raising your risk of vein problems.
