After kidney transplantation, if in the condition of normal renal function, protein intake should be controlled at 1.4g/kg/d in the first 3 months. after 3 months, protein intake should be controlled at 0.6~0.8g/kg/d. Kidney transplantation is a common treatment for end-stage renal disease. After kidney transplantation, in addition to the use of medication, there should also be some control of diet every day to maintain the stability of the body’s internal environment. Regarding the protein intake after kidney transplantation, because of some of the medications used, such as immunosuppressants, which will inhibit protein synthesis and accelerate the decomposition of protein, it will make the protein in the patient’s body consume too fast, so the diet needs to be appropriately more high-quality proteins. High protein diet with protein intake of 1.4g/kg/d is recommended within 3 months after transplantation, and restricted/restricted protein diet with protein intake of 0.6~0.8g/kg/d is recommended for >3 months after transplantation, and supplementation of compound α-keto acid preparation of 0.12g/kg/d is also recommended. Postoperative dietary matters for kidney transplant patients need to visit regular hospitals and consult doctors for guidance.
