How do healthy veins work?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Veins return oxygen-depleted blood from the body back to the heart. Because blood in the legs must travel against gravity, veins rely on one-way valves and the calf muscles to maintain forward blood flow.<\/p>

Every time you walk, your calf muscles act as a \u201csecond heart\u201d, squeezing the veins and pushing blood upwards. Healthy vein valves prevent blood from flowing backwards.<\/p>

When these valves weaken or become damaged, blood leaks backwards (venous reflux), causing increased pressure within the veins. Over time, this may lead to varicose veins, chronic venous insufficiency, leg swelling and skin changes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
