Varicose veins are twisted, swollen veins that often appear on the legs, but can appear anywhere else on the body. Usually, our veins carry blood against gravity. Hence, they have special valves which close at specific intervals to prevent the backflow of blood. However, sometimes when the valves don’t close properly, the blood begins to pool around the valves, thus leading to varicose veins.
Let us see some causes of varicose veins. Firstly, during pregnancy, the increasing volume of blood and uterus put pressure on the veins, eventually leading to varicose veins. Secondly, being overweight leads to increase in pressure on the veins, thus causing varicose veins. Lastly, due to prolonged periods of standing or with age, our valves can get weaker, thus increasing the risk of varicose veins. Note that varicose veins can be painful, and they can lead to blood clots, ulcers and bleeding.
