Nephrotic syndrome is a group of symptoms caused by chronic nephritis, characterized by symptoms such as large amounts of proteinuria, severe edema, hypoalbuminemia, and hyperlipidemia. For patients with normal renal function or mild damage with little proteinuria loss and normal serum protein levels, a general diet can be adopted, but salt intake should be restricted. For patients with greater proteinuria loss or low serum protein levels but normal renal function indicators, appropriate protein intake can be increased. However, a long-term high-protein diet may be detrimental to chronic nephritis patients. Current treatment methods include the use of hormones, immunosuppressants, anticoagulants, lipid-lowering drugs, and traditional Chinese medicine.
