Wondering what causes spider veins? Learn about the factors that trigger this condition, including weight, excess time spent standing or sitting, and more.
Even if you have spider veins, you may not know what causes this condition. All sorts of things can contribute to spider vein formation, including several factors you may not have expected.
Here, you’ll find a full explanation of spider veins and what can cause them. Along with that, you’ll get valuable tips on how to prevent and treat spider veins.
Spider Veins: Understanding the Basics
Spider veins (or “thread veins”) get their name from their appearance, which can resemble a “web” of thin lines. Though they can be unsightly and uncomfortable, spider veins are not actively harmful in most situations.
For the most part, spider veins occur because of damage to or weakness in a person’s veins. While they are commonly found in the legs, they can also show up in places like your chest, back, abdomen, or face (especially near your nose, chin, cheeks, or under your eyes).
Spider Veins vs. Varicose Veins
In many ways, spider veins and varicose veins are similar. These are both types of “venous insufficiency,” a condition resulting from damaged or weakened valves in leg veins.
However, there are also some crucial differences between these issues. Generally speaking, spider veins are thin, small lines that are flat (or slightly raised) and colored blue, purple, or red. In contrast, varicose veins are usually deeper and larger than spider veins and can look “twisted” or “lumpy.”
The symptoms associated with these veins can also vary considerably. For the most part, spider veins do not create problems beyond occasional discomfort. That isn’t the case for varicose veins, which can cause symptoms such as:
- Pain
- Bleeding
- A “heavy” or “achy” feeling in the legs
- Itching
- Swollen legs and ankles
- An increased risk of circulation problems/blood clots
What Factors Can Increase Your Risk of Spider Veins?
Spider veins do not have a single underlying cause; instead, a number of factors can contribute to their development. Some things that can make a person more likely to develop spider veins include:
1. Genetics
The vast majority of people who develop spider veins aren’t the first people in their families to deal with them. Instead, 90% of all people with spider veins have a family history of this issue.
2. Sex
Spider veins are considerably more common in women than in men. This condition affects nearly twice as many females as males, to the point where 41% of women aged 50 and older develop spider veins.
3. Pregnancy
Being pregnant can also contribute to the formation of spider veins. This is due to extra blood flow during pregnancy, as well as the extra weight fetuses place on leg veins.
4. Standing (Or Sitting) for Extended Periods
Staying in the same position for a long time can make you more likely to develop spider veins (regardless of what position you’re in). If you stand up or sit down for more than four hours, your veins will have to work harder to keep blood traveling to your heart.
5. Excess Weight
The more body weight you have, the more pressure your leg veins have to deal with. As a result, people who are overweight or obese have a heightened risk of spider vein development.
While these factors are certainly worth paying attention to, there are other contributors to spider veins you should know about. Other things that can increase your spider vein risk include a history of blood clots, UV damage from the sun, age, and excess pressure in the face from coughing, sneezing, or vomiting.
How to Prevent and Treat Spider Veins
While spider veins are normally harmless, you’ll still want to know how to avoid them. With that in mind, here’s what you should understand about spider vein:
Prevention
Though some spider vein-related factors are out of your control, there are ways to reduce your risk of developing this issue. If you want to stop spider veins in their tracks, take steps such as:
- Using sunscreen. Daily sunscreen applications can prevent spider veins (especially on your face).
- Wearing compression stockings. Compression stockings and socks place gentle pressure on the veins in your lower legs. That pressure can improve blood flow in these extremities and lower your risk of spider veins.
- Elevating your legs. Raising your legs while lying down or sitting can stop blood from pooling there.
- Maintaining or reaching a moderate weight. Being overweight can put added pressure on your leg veins, and losing weight is an excellent way to avoid this.
- Keeping active. If you want to avoid spider veins, you should try not to sit or stand for too long. Meanwhile, regular physical activity can help you lose weight and improve your circulation.
- Not spending too much time in hot tubs/saunas. Veins can swell in response to excess heat, which could result in bulging and dilated veins in your legs.
- Avoiding excess alcohol consumption. In some people, alcohol can lead to flushing in the face and broken blood vessels.
Treatment
Meanwhile, some common types of spider vein treatment include:
- Laser treatment. For small spider veins, healthcare professionals can use laser treatments. Exposure to this beam will cause the spider vein to clot, resulting in it drying up.
- Sclerotherapy. This is the most effective spider vein treatment available today. If you visit a clinic for sclerotherapy, a healthcare professional will inject an irritant into a spider vein. In response to this substance, the vein will stick together, ultimately causing it to shrink and fade.
