What causes varicose veins?
Varicose veins result from improper venous function, leading to blood pooling in the veins. In general, varicose veins can be caused by valve malformations, pregnancy, and thrombophlebitis, which is vein swelling due to a blood clot. Extended periods of time standing on your feet without motion can also lead to varicose veins. Varicose veins that are due to valve defects which are present from birth or have no known cause are called primary varicose veins, while those that develop because of another condition are considered secondary varicose veins.
