Spider veins, medically known as telangiectasias, are small, thin, visible blood vessels that appear close to the surface of the skin. They often look like red, blue, or purple lines, webs, or branches, resembling a spider’s web, hence the name.
Spider veins derive their name from the clusters they form, which resemble spider webs. They’re most commonly found on your face, legs or abdomen. Although related to varicose veins, spider veins rarely become painful and don’t get as large as their twisted, bulging counterpart. Your doctor diagnoses whether you have surface spider veins or deeper varicose veins.
While varicose and spider veins differ from each other, they can both be prevented with similar means. Whether you’re just beginning to notice the first faint signs of spider veins, or weak blood vessels are common in your family, talk to your vein doctor about prevention, either before they become a problem or after you’ve them once. Steps to reduce spider veins include:
Spider veins result from weakened valves in your veins that don’t adequately shut after blood flows through them. Faulty valves cause the blood to pool or even flow backward. Where this happens, your blood vessels weaken and thin. They can rupture, bulge or darken, causing varicose veins and spider veins.
Spider veins are a relatively common condition, occurring in about 40 percent of women, and close to 30 percent of men. Genetics also play a role in the development of spider veins, while standing for extended periods puts you at a higher risk. Other causes include:
Unlike the pain and throbbing associated with varicose veins, you usually don’t feel painful symptoms with spider veins. Spider veins can be uncomfortable, but rarely painful. Some of the mild symptoms include:
One of the most safe, successful and effective treatments is sclerotherapy. Your specialist injects the spider veins with a solution that causes them to collapse. After the veins are reabsorbed into your body and the blood flow is cut off, the red or blue web-like lines fade within a few weeks. Sclerotherapy is nearly 90 percent effective when performed by a trained physician.
Another popular spider vein treatment relies on lasers. This treatment works particularly well on thinner spider veins that are difficult to treat by injection. Laser heat pulses under your skin, where the spider veins appear. The result is the same as sclerotherapy.
While spider veins are usually harmless, some people choose to treat them for cosmetic reasons or if they cause discomfort.
