Varicose veins of the lower extremities are common in people who work in a standing position for a long period of time, who have high intensity of physical activity, and who are sedentary. Therefore, patients with varicose veins of the lower extremities should not engage in heavy physical activities such as weight lifting, soccer, basketball and squatting. Standing work, high intensity of physical activity or sedentary behavior makes the vein valves of the lower limbs under excessive pressure, gradually become loose and finally fail to close tightly. The normal flow of blood from the veins back to the heart (i.e., the bottom-to-top process) is mainly due to the action of the venous valves. Once the valves do not close tightly, blood accumulates in the veins of the lower extremities and varicose veins develop. Varicose veins can be treated by wearing medical compression stockings or elastic bandages, or at a later stage by sclerotherapy injections or surgery. This operation should be done under the guidance of a specialized doctor. If you have any of the above conditions, please consult a doctor in time for a reasonable and standardized treatment. Daily exercise should choose swimming, yoga, walking and other sports.
