Varicose veins are enlarged, bulging veins that most commonly appear on the legs. Some patients notice them because of appearance alone, while others seek care because of aching, heaviness, swelling, or leg fatigue.
Although varicose veins are common, they are often misunderstood. Some people assume they are only cosmetic, while others worry they may indicate a more serious circulation issue.
This page provides a comprehensive overview of varicose veins, answers the most common patient questions, and explains when evaluation and treatment may be helpful.
If you’re unsure whether your varicose veins are cosmetic or a sign of vein disease, a vein evaluation can help clarify what’s happening.
What are varicose veins?
Varicose veins are enlarged veins that develop when blood does not flow efficiently back toward the heart, causing veins to stretch and become visible.
They most often affect the legs, where veins work against gravity, and can range from mildly enlarged veins to prominent bulging veins.
What causes varicose veins?
Varicose veins develop when the valves inside the veins weaken or fail, allowing blood to flow backward and pool in the vein.
Common contributing factors include genetics, aging, pregnancy, prolonged standing or sitting, and increased pressure in the leg veins.
What symptoms are associated with varicose veins?
In addition to visible veins, many patients experience aching, heaviness, swelling, throbbing, itching, or leg fatigue.
Symptoms often worsen throughout the day or after long periods of standing.

Are varicose veins dangerous or just cosmetic?
Some varicose veins are primarily cosmetic, while others may signal underlying venous insufficiency.
Knowing when varicose veins are harmless and when they require medical attention helps guide appropriate care.
Can varicose veins go away on their own?
True varicose veins usually do not disappear without treatment because valve dysfunction does not reverse on its own.
Symptoms may fluctuate, but the underlying vein issue often remains.
How are varicose veins diagnosed?
Diagnosis usually includes a physical exam and a non-invasive ultrasound to evaluate blood flow and valve function.
Ultrasound helps determine whether deeper vein reflux is contributing to visible veins and symptoms.
What are the treatment options for varicose veins?
Modern treatment focuses on improving circulation using minimally invasive, non-surgical procedures.
Treatment selection depends on vein anatomy, symptoms, and ultrasound findings.
