The main danger of standing at work for a long time is that it will lead to venous insufficiency of the lower limbs and induce varicose veins. Patients who stand for a long time at work will cause the venous pressure in the lower limbs to increase, which, together with their venous insufficiency, impaired venous valve function, and weak congenital venous walls, will over time lead to more pronounced and even tortuous expansion of the blood vessels in the lower limbs and the formation of varicose veins. Therefore, standing for a long time is the most common clinical risk factor that triggers varicose veins. For such patients, it is recommended that they avoid sitting or standing for a long time and put their legs up when resting to be able to delay the chance of varicose veins. In addition, if you stand for a long time at work, you can wear medical compression stockings to prevent the occurrence of varicose veins. If the varicose veins are not clearly visible, it is recommended to wear compression stockings of the first level of compression prevention; if the veins are clearly visible or even tortuous and dilated, compression stockings of the second level of compression treatment should be worn. In case of more serious varicose veins, it is necessary to go to a specialized vascular surgery department for systematic consultation and treatment.
