Varicose veins often affect the legs, since they are the farthest from the heart and gravity makes it harder for the blood to flow upward.
According to The Franklin Institute’s human heart data, if every capillary, artery and vein were laid out in a straight line, the average adult has 100,000 miles worth of blood vessels.
Although the vessels in all areas of the body work hard, those in the legs and feet are susceptible to a lot of pressure, as walking increases the stress put on these vessels.
In turn, varicose veins are common in the lower limbs.
Veins can become varicose when one-way valves in the veins do not function properly.
Varicose veins often cause numbness, pain and fatigue in the legs.
