Anemia is a common disease, but it is also closely related to the kidney. We often see in the hospital for some pale, loss of appetite patients come to the Department of hematology. After renal function examination, it was found that the patient not only had severe anemia but also in the late stage of nephropathy.

Knowledge of renal failure: chronic renal failure and multiple systems

In general, anemia can occur at various stages of chronic renal failure. Because some patients without a clear history of the kidney, and never had a urine test, once found his face is often mistaken for iron deficiency anemia. In fact, this is a renal anemia, it is a common complication of chronic renal failure. The main cause of renal anemia is the deficiency of erythropoietin in the kidney of chronic renal failure. About 90% of erythropoietin in the human body is produced by the kidney, which plays a key role in regulating the normal division, development and maturation of red blood cells. In the case of chronic renal failure, with the destruction of renal units, the production and secretion of erythropoietin in the kidney will be reduced, leading to renal anemia.

But lacking of erythropoietin is not the only reason for renal anemia, many other factors are also involved in the formation or cause of renal anemia, such as shortening the life of red blood cells, iron deficiency, folic acid deficiency, malnutrition, chronic inflammation, chronic blood loss (via gastrointestinal loss), severe hyperparathyroidism, aluminum poisoning and hypothyroidism. Renal anemia can cause a series of adverse consequences, affecting almost every organ system in the body. In the field of cardiovascular disease, cardiac enlargement, cardiac hypertrophy caused by increased incidence of cardiovascular events (such as coronary events, heart failure and cerebral infarction), congestive heart failure and death is an independent predictor of progression of nephropathy; acceleration and renal function; cause cognitive dysfunction; menstrual disorders, sexual dysfunction; immune function decline; influence of the quality of life, death and increased hospitalization time etc..

Therefore, it is necessary to remind patients, once found to have their own symptoms of severe anemia, do not forget to carefully check your kidneys, diagnosed with renal anemia should be actively cooperate with the correct attitude.
