Question
The patient is a 60-year-old female with renal insufficiency and anemia, currently undergoing erythropoietin injection treatment, and inquiring about the suitable iron supplement.
Answer
For patients with anemia caused by chronic renal insufficiency, the cause of anemia is related to kidney disease. Therefore, correcting anemia can be done by injecting erythropoietin or taking oral blood-building medications. However, if the hemoglobin level is 81, which is considered moderate anemia, oral iron supplements may not be effective in correcting the anemia, and erythropoietin injection is usually required. It is recommended to further check the glomerular filtration rate. If it reaches the criteria for renal replacement therapy, consider undergoing replacement therapy, as the root cause of the anemia is still the kidney disease.
