Spider veins, those small, web-like clusters of red, blue, or purple lines, often appear on the legs and can leave many people wondering why they develop in the first place. While they’re typically harmless, spider veins can be a cosmetic concern and sometimes signal underlying circulation issues. Understanding what causes them is the first step toward finding relief.

As the Pacific Northwest’s largest vein-focused practice, Inovia makes high-quality vein care accessible and affordable without costly hospital visits.
What Causes Spider Veins?
Spider veins occur when tiny blood vessels near the skin’s surface dilate. This happens due to increased pressure in the veins, often from weakened or damaged valves that allow blood to pool instead of flowing efficiently back to the heart. Over time, this pressure buildup causes the veins to stretch and become visible.
Common Risk Factors
Several factors can increase your chances of getting spider veins, especially on your legs:
- Genetics: If your parents had spider veins, you’re more likely to develop them too.
- Age: As you age, vein valves may weaken.
- Prolonged Standing or Sitting: Jobs that involve long hours on your feet or in a chair can lead to poor leg circulation.
- Hormonal Changes: Pregnancy, menopause, or hormonal therapies can trigger vein changes, especially in women.
- Obesity: Excess weight adds more pressure on your leg veins.
- Sun Exposure: While this mostly affects facial veins, prolonged sun exposure can also contribute to spider veins on the legs.
Should You Be Concerned?
In most cases, spider veins are not a health threat, but they can be a sign of chronic venous insufficiency, a more serious circulation problem. If you experience leg pain, heaviness, swelling, restless legs, and visible veins, it’s a good idea to consult a vein specialist.
