What best describes varicose veins?

• A. Where blood pools in veins
• B. A narrowing of arteries due to plaque
• C. An infection of the vein
• D. A healthy vein with normal valves

Answer: (A)

Varicose veins occur when the valves inside leg veins don’t close properly, allowing blood to flow backward and pool in the veins. This venous pooling increases pressure, causing the veins to stretch, twist, and bulge under the skin. That pooling is the hallmark feature, which is why this option best describes varicose veins.

It’s not about arteries narrowing from plaque, which is an arterial issue (not veins). It’s not an infection of the vein, and it’s not a healthy vein with normal valves—varicose veins are an abnormal dilation due to venous valve incompetence and blood pooling.
