Spider Vein Basics

If you are scared of household spiders, then you might be equally as scared of spider veins. Spider veins or telangiectasias are small thin blood vessels underneath the skin that typically look like a series of thin branches or a spider web. Although spider veins typically aren’t as painful or noticeable as varicose veins, they can cause symptoms such as aching, swelling, leg-cramping, and burn. To help you understand a little bit more about spider veins, let’s take a closer look at some of the basics.

Spider Veins Are Common

Spider veins aren’t necessarily something you talk to strangers about or even friends about at the dinner table. So, you might know more people who have spider veins than you may be aware of. Spider veins are extremely common and affect nearly half of the population of adults in the United States.

What Causes Spider Veins?

Spider veins are caused when there is a backflow of blood in the veins. This condition is called “venous reflux.” As the blood collects in the veins, their walls distend and lead to spider veins.

What Risk Factors Increase Your Chances of Developing Spider Veins?

Genetics play a huge role. If you have a family history of spider veins, you are likely to have them yourself. Women who are pregnant may notice spider veins as the extra weight and pressure on their leg veins during pregnancy can cause them. Women in general tend to get spider veins more often than men. 

As vein valves get weaker over time, it’s no wonder that aging is a factor. Being overweight can contribute to the development of spider veins. Hormones also play a role because estrogen is known to weaken vein valves. 

If you sit or stand for long periods of time, the veins in your legs have to work harder to pump blood toward the heart. If you have previous vein damage or a blood clot, you are more at risk.

Spider Veins Can Appear All Over The Body

Unlike varicose veins that are primarily on the feet, calves and feet, spider veins can be on the legs, face, genitals, and abdomen.

Spider Vein Treatments

Here at Texas Vein & Wellness Institute, we offer patients a variety of spider vein treatments. Depending on the severity of your spider veins, we may recommend that you make simple lifestyle changes like weight loss and regular exercise. If these changes don’t work, we may also recommend either compression stockings or a treatment called sclerotherapy. Sclerotherapy is a treatment that involves injecting the affected veins with a solution like saline. Once they are injected, it causes them to collapse and ultimately dissolve.
