As you age, tiny valves inside the veins in your legs can begin to wear out or get damaged, from either standing too long at a time, too much uninterrupted sitting over the years or other risk factors. These damaged valves result in what's called venous insufficiency – not enough blood flow. When there's not enough blood flowing in the legs, the blood that is there can build up inside the veins. This can lead to vein swelling and what becomes a varicose vein.
