5 Causes of Spider Veins and Treatment Options

Do you have spider veins? Are you wondering what could be causing them and what to do about them? If so, then we can help here at Advanced Vascular Associates. Here are the common causes of spider veins and treatment options.

Many people have spider veins, and many of us don’t appreciate them at all. They can be unsightly, which can make us uncomfortable in our own skin. They usually aren’t much more of a problem than that, but that’s still a significant problem! So what are the causes of spider veins and treatment options? Here are some of the most common causes along with the treatments we recommend.

Damaged or weakened veins in the legs

In our legs, spider veins can occur when valves inside our veins aren’t working well anymore. If these valves are weakened or damaged, blood won’t easily flow through them and might start to pool inside. This is what usually causes spider veins in the legs. Typically, weak or damaged veins are a result of aging.

The best treatment for spider veins in the legs is usually sclerotherapy. This procedure is relatively simple and only minimally invasive. The veins are injected with a solution that causes them to collapse, and then the body gets rid of them naturally! Right away after, the body finds healthier veins to route blood through.

Damaged blood vessels in the face

Some people get spider veins around their face, and these particular spider veins are caused by tiny blood vessels in the face that have burst. This can happen as a result of too much pressure in the area, or overexposure to the sun.

Facial spider veins are easily treated with laser vein treatment. This kind of treatment is entirely noninvasive. A harmless laser is used to heat the spider veins, which destroys them. Then the body eliminates the veins naturally, and finds healthy veins to route blood through.


This is one of the most common spider veins causes. Most people who have spider veins also have a family member with them. In fact, around 90% of people with spider veins have a family history of them. Spider veins caused by genetics can occur in many different places of the body. Depending on the location and the size of the veins, either laser treatment or sclerotherapy can treat them.

Pregnancy or being overweight

Women are at greater risk for spider veins. Pregnant women are at an even greater risk. This is because during pregnancy, there is increased blood flow in the body, and the extra weight during pregnancy puts more pressure on leg veins. For people who are overweight or obese, the extra weight has a similar effect on the veins.

Often, spider veins resulting from pregnancy go away after pregnancy. However, sometimes they do not, and a woman might want to have them treated. Sclerotherapy is the best treatment in most of these cases, and it’s the best treatment for veins caused by excess weight, in general.

Sitting or standing for extended periods

If you work a job that requires that you sit or stand for a long time, then you might develop spider veins. Or maybe you spend too much time on the couch? When you spend too much time in a stationary position, your veins have to work harder to pump blood. This can cause spider veins in the legs, which can be treated with sclerotherapy. Sclerotherapy is one of the most effective (and cost-effective) spider vein treatment options.
