Large. Raised. Swollen. Twisted. These are three words commonly used to describe varicose veins.

Smaller. Red. Purple. Blue. Twisted. These describe spider veins, which are a similar skin condition to varicose veins.

The cause of spider veins cannot be narrowed down to one piece of evidence. Someone may get spider veins because of their genetics, their occupation, their lifestyle, or other bodily conditions.

Essentially, spider veins are caused when there is more blood flowing through the vein than it can typically handle. But, what causes the body to form spider veins depends on the person.

Today, our team takes a look at the different causes of spider veins.

Spider Veins May Be Caused By…


Spider veins are suspected to be hereditary. It is not clear which piece of the genetic profile leads to spider veins. However, if your elder relatives have spider veins, you most likely will too.

It is important to start prevention practices as soon as possible, so if your family has spider veins, you should see an expert soon to help reduce your own risk. Knowledge is power, especially when it comes to your physical health.

Folks who have a physically demanding job are at a higher risk for developing spider veins. Since spider veins typically form first in the legs, the excessive time spent on foot confuses the circulatory system. The lower part of the body demands more, which causes the body to send more blood. Unfortunately, this can be dangerous. Nurses, teachers, factory workers, hair stylists, and others in similar positions are more susceptible to developing spider veins than those in other positions.

Lifestyle Choices

Obesity is a cause for spider veins. While obesity is sometimes out of our control, the excess weight one carries around can cause additional stress on the body. This physical stress can cause the veins to enlarge and appear through the skin.

Another lifestyle choice that can lead to spider veins is the use of birth control. Some forms of birth control cause vein walls to weaken because of an increase of estrogen and progesterone. Similarly, a woman may experience spider veins if she elects a postmenopausal hormonal replacement.

Other Bodily Conditions

Along the same lines as birth control causing spider veins, natural hormonal changes can also cause spider veins. Most people experience a spike in estrogen and progesterone during puberty, pregnancy, and menopause.

Medical history can play a lot into whether you develop spider veins. Regular blood clots, weakened vein valves, and skin damage can weaken veins.

Spider Vein Treatment

You can treat spider veins with lifestyle changes and medical treatments, depending on the cause. A lifestyle change will likely be the first treatment recommendation if your spider veins do not cause any serious symptoms. Otherwise, medical treatment may be the ideal next step. Treatments like sclerotherapy, surface laser treatments, endovenous techniques, and surgery are common to alleviate the stress on the body, which heal the spider veins.
