Varicose Veins

Varicose veins are enlarged, twisted veins that typically appear on the legs and feet. They occur when veins do not function properly, leading to blood pooling. While they are mostly a cosmetic concern, they can sometimes lead to discomfort or other issues.

    Varicose veins form when the one-way valves in your veins become weak or damaged, allowing blood to back up and pool in the veins. This causes the veins to swell and become twisted.

    Legs are the most common place for varicose veins because they have to work hardest against gravity to push blood back up to your heart. When the valves in leg veins weaken, blood pools there and causes swelling.
