Spider Veins: Causes, Symptoms and Modern Treatments

Discover what causes spider veins and the best treatment options including sclerotherapy and laser therapy.

Spider veins are a common vascular condition that affects both men and women, often appearing as small red, blue, or purple veins near the surface of the skin. Although they are usually harmless, many patients seek treatment because of their cosmetic appearance or mild discomfort.

Understanding what causes spider veins and how they can be treated helps patients make informed decisions about their vascular health.

What Are Spider Veins?
Spider veins, medically known as telangiectasias, are small dilated blood vessels visible through the skin.

They commonly appear:

• On the legs
• Around the ankles
• On the face

Their web-like pattern resembles a spider’s legs, which is how they get their name.

Causes and Risk Factors
Spider veins often develop due to increased pressure in the veins.

Common causes include:

• Genetic predisposition
• Hormonal changes
• Pregnancy
• Prolonged standing
• Sun exposure (for facial spider veins)
• Aging

Symptoms and Warning Signs
Spider veins are usually painless but may sometimes cause:

• Mild itching
• Burning sensation
• Leg fatigue

Diagnosis and Medical Evaluation
A vein specialist evaluates the veins visually and may perform a duplex ultrasound to rule out underlying venous insufficiency.

The most effective treatments include:

Sclerotherapy
