Spider veins are small, damaged blood vessels that appear on the skin’s surface of the legs or face. They typically present as thin, branching lines that form a web-like pattern, appearing in shades of red, blue, or purple. Spider veins may be noticeable, but they’re generally harmless and often don’t cause symptoms. Here’s more information on these veins and how common they are:
What Causes Spider Veins?
Spider veins develop when the tiny one-way valves inside surface blood vessels weaken or stop functioning correctly. When these valves fail to push blood forward efficiently, the blood backs up and pools inside the vessel. This causes the veins to swell, making them visible under the skin. Genetics plays a significant role in their development, and hormonal changes often contribute to their appearance. Other contributing factors include prolonged periods of standing or sitting, aging, and carrying excess body weight.
These noticeable veins are common in adults, and by age 80, most individuals have them. Spider veins tend to occur more frequently in women than in men, largely due to hormonal fluctuations during pregnancy, menstruation, and menopause. The likelihood of developing them also increases with age, as the valves in the veins naturally lose elasticity and strength over time. For most individuals, spider veins are purely visual, but some people may experience leg symptoms like:
- A Mild or Dull Ache
- Heaviness
- Swelling After Prolonged Sitting
How Are They Diagnosed?
To diagnose spider veins or other venous health conditions, you must visit a vascular specialist for an evaluation. A healthcare professional can diagnose spider veins through a visual examination of the affected area. During a consultation, the provider will review your medical history, ask about any discomfort, and examine your veins. Your specialist may utilize an ultrasound to evaluate blood flow and check for underlying vascular conditions, such as venous insufficiency.
Venous insufficiency occurs when the veins in your legs have trouble sending blood back to the heart. The one-way vein valves are damaged, so they fail to function properly. This condition causes blood to pool in the lower extremities, increasing venous pressure and contributing to the formation of spider and varicose veins. Varicose veins are enlarged, twisted veins that are more severe and often cause discomfort.
What Can Treat Them?
Providers recommend wearing compression stockings, which apply gentle pressure to the lower legs to help blood flow toward the heart. Conservative management methods often begin with lifestyle adjustments to improve circulation. Some other at-home methods to improve circulation include:
- Elevating the Legs While Resting
- Engaging in Regular Physical Activity
- Avoiding Prolonged Periods of Uninterrupted Sitting or Standing
Endovenous Laser Ablation Treatment
Endovenous Laser Ablation Treatment is a minimally invasive procedure used to address problematic veins. During this procedure, a specialist uses focused laser energy to heat the targeted blood vessel. The heat causes the walls of the vein to close and seal off. Once the vein is closed, the body naturally reroutes blood flow to nearby, healthier veins, causing the treated vessel to fade from view over time.
Sclerotherapy
Sclerotherapy is the standard procedure for treating spider and varicose veins, as it is highly effective at reducing them. A specialist injects a chemical solution directly into the affected vein, and the vessel gradually collapses over the following weeks. The solution irritates the blood vessel lining, causing it to scar and forcing blood to reroute through healthier veins. The collapsed vein is eventually reabsorbed into the body and fades away.

Maintaining a healthy weight reduces pressure on the veins in the lower body, which can help prevent new spider veins from forming. To learn more about your vein health, schedule a consultation with a vein clinic. Don’t wait for new veins to develop before establishing a provider; contact a specialist today.
