Varicose veins can be treated with oral aspirin, but if varicose veins are operated, it is recommended to stop aspirin and switch to low molecular heparin, which can reduce bleeding during and after varicose vein surgery. The cause of varicose veins will not be changed by taking aspirin, but oral aspirin can prevent the formation of blood clots in varicose veins to some extent and can keep the varicose veins blood flowing smoothly. The main causes of varicose veins are venous hypertension, venous stasis and venous reflux disorders, but aspirin is an anti-platelet aggregation drug that does not play any role in causing these causes of varicose veins. So varicose veins can be taken orally with aspirin and the patient will not have any effect on varicose veins while taking oral aspirin.
