Stretch pants are very significant in the treatment of varicose veins, whether it is conservative treatment of varicose veins or surgical treatment, compression therapy is very significant in the recovery of varicose veins throughout the treatment process. Part of compression therapy is the wearing of elastic stockings, elastic bandages or elastic pants to treat varicose veins. The principle of compression is to reduce the venous pressure within the varicose veins by reducing the varicose veins and blood stagnation, which can effectively improve the circulation. The principle of elastic pants is to use graded gradients of pressure, which means that the pressure is not the same. The pressure is higher in the lower part of the body and lower in the upper part of the body, which can produce a pressure difference, which can promote the return of blood to the veins and can reduce the progression of varicose veins, as well as reduce the symptoms caused by varicose veins.
