First, control protein's intake and diet. Proteinuria is one of the common phenomena of nephrotic syndrome. Many patients are accompanied by proteinuria, resulting in the loss of protein in the body, which brings serious harm to patients, so it is necessary to supplement them from the diet. The diet of sick children should contain enough protein, such as fish, lean meat, poultry and bean products.

Second, control the daily diet and beware of hyperlipidemia.
