Varicose Veins Cause

Wondering why varicose veins form on your legs? Varicose veins are caused by vein valves and walls that have become weak or damaged. This damage doesn’t happen overnight. It occurs over time when the blood pressure in your veins increases for various reasons. Other factors that can increase blood pressure, such as being overweight, pregnancy, or smoking can also weaken vein walls and valves.
