What Causes Spider Veins?

What Causes Spider Veins?

Spider veins are extremely common, but that doesn’t make them any less unappealing. Good leg circulation will help prevent them, and there are treatments that will erase them.

Spider veins get their name from the web of red or blue veins that often start to spread across your legs as you age. They’re dilated superficial blood vessels like varicose veins, but smaller and closer to the skin. Spider veins are often in areas behind the knee, says Douglas Joseph, DO, a vascular medicine specialist at the Cleveland Clinic in Ohio, but they can appear anywhere on the body.

To show just how common spider veins are, a group of researchers looked at 1,566 people and found that 84 percent had spider veins — called telangiectasia in medical jargon — on their right legs alone. While they don’t usually cause medical problems, they can be eliminated for medical or cosmetic reasons with procedures such as laser treatment and sclerotherapy.

Who Gets Spider Veins?

Spider veins are caused by increased pressure in the veins, Dr. Joseph says. Doctors don’t know exactly why some people develop spider veins and others don’t, but they do know that the tendency to get them is hereditary, and that they’re more common as you get older. It’s also known that people who stand for a long time, such as nurses and teachers, tend to increase the amount of pressure in the veins of the legs and are more likely to develop spider veins, Joseph says.
