Patients with diabetic nephropathy who exhibit anemia are often in a state of chronic renal failure. This anemia caused by chronic kidney disease is mainly due to the decreased secretion of erythropoietin by the kidneys. Therefore, treatment involves the use of erythropoietin to stimulate bone marrow hematopoiesis. In addition to this medication, patients generally also need to supplement with iron preparations, such as ferrous succinate, sucrose iron, etc., and take oral folic acid, all of which are raw materials for blood formation. Furthermore, if patients have severe malnutrition, they should also supplement with foods rich in protein, such as eggs, milk, chicken, duck, fish, etc. (Please use medications under the guidance of a doctor.)
