The veins that can be seen on the surface of the body are all reflux veins, and many women have obvious veins on their hands, mainly because some women have thinner skin and lighter skin color, which makes it easier to expose the veins, so they are obvious, but most of them are physiological changes and do not need special treatment. Because the hand is located closer to the heart, it is not prone to excessive pressure in the blood vessels, which can lead to varicose veins as in the lower extremities, so this condition also does not require treatment. If it occurs after a blood clot or is often accompanied by edema in the hand, this condition should be examined with ultrasound to exclude blood return disorders.
