Swelling of the feet is a common phenomenon in nephrotic syndrome. Once swelling occurs, patients feel uncomfortable symptoms and a sensation of heaviness in their feet, so corresponding de-swelling treatment is necessary. How to reduce swelling? Firstly, a low-salt diet is essential to control salt intake, with daily salt consumption around 2 to 3 grams. In addition to this, small doses of diuretics such as hydrochlorothiazide and spironolactone can be used. If the diuretic effect is not satisfactory, other more potent diuretics like furosemide may be added. Of course, the fundamental treatment for foot swelling in nephrotic syndrome involves the use of steroids and immunosuppressants. This treatment works by suppressing the permeability of the glomerular basement membrane and reducing protein leakage, thereby ultimately eliminating the foot swelling.
