Normal renal function in nephrotic syndrome indicates that the disease has not progressed to the stage of renal failure. Nephrotic syndrome is a combination of glomerular injury and increased permeability caused by a variety of reasons, resulting in massive proteinuria with edema, hyperlipidemia and hypoproteinemia. 1.Complications of nephrotic syndrome include: (1) thrombus: excessive water and protein loss, blood concentration prone to thrombus formation. (2) Infection: Nutritional loss of resistance to infection. (3) renal failure: various factors easily lead to acute attacks, need to actively treat the primary disease and the correct symptomatic supportive treatment. 2. Treatment: bed rest, low-salt, low-fat, high-quality protein diet, symptomatic treatment, such as diuretics, diuretic swelling, lipid-lowering, etc., and suppression of immune and inflammatory response, such as glucocorticoids (methylprednisolone, prednisone acetate, etc.) and immunosuppressants (cyclophosphamide, cyclosporine, etc.) of the reasonable application. It is recommended that patients go to the hospital in a timely manner, under the guidance of the doctor to carry out the relevant diagnosis and treatment.
