The reason for varicose veins in legs often comes down to weakened or damaged veins that struggle to carry blood back to the heart. Veins have one-way valves that keep blood flowing upward, but when these valves fail, blood can pool in the legs, causing veins to bulge and become twisted. This leads to the discomfort and visible changes many people notice.
