What are Spider Veins and Varicose Veins?

Spider veins, or telangiectasia, are small veins in the skin that appear web-like and red, blue or purple in color. They occur when one-way valves in the blood vessels no longer work properly, causing blood to clot instead of flowing back to the heart. 

Varicose veins are enlarged, bulging, twisted, and often darker in color than spider veins. They are near the skin surface and are caused by leaky valves in veins deeper in the leg. This makes the veins widen, often becoming unsightly and uncomfortable.

Untreated, varicose veins typically worsen over time. 

Spider veins and varicose veins can affect women and men of any age, but they are most common in women of childbearing age or older.
