The blood vessels on the feet are particularly obvious in two cases: the first case is physiological and does not require special treatment, while the other case is varicose veins and requires attention to changes in the condition. For the first case, it is mainly because the dorsal foot veins are relatively superficial and the subcutaneous tissue is relatively small, so the blood vessels on the feet will look more obvious, as long as they are not accompanied by varicose blood vessels in the feet, they are normal. The second condition is brought about by varicose veins, due to the weakened elasticity of the blood vessel wall and incompetent valves after prolonged standing or heavy physical labor, which cause blood to reflux and accumulate in the calf causing tortuous and dilated veins in the foot. This condition is a pathological change that requires avoiding long periods of standing and sitting, elevating the affected limb at rest to promote venous reflux, and improving the venous pressure in the lower limbs by wearing varicose veins stockings to reduce swelling.
