Severe varicose veins are usually recommended for surgical treatment, while milder varicose veins can be controlled by effective preventive methods. Avoid prolonged standing and standing because varicose veins are mainly caused by venous reflux and prolonged standing can increase the venous pressure and aggravate the symptoms of varicose veins. Also people who are engaged in standing for a long time can wear medical elastic stockings, which are an effective way to prevent varicose veins. You can also do some sports with little exercise, such as swimming, walking, yoga, etc. can make the veins reflux through muscle contraction, slowing down the development of varicose veins, in addition to exercise can increase the elasticity of the tissue, playing a role in the symptoms of varicose veins.
