Why anemia due to renal insufficiency

summary

Grandfather was diagnosed with renal insufficiency a few years ago. He thought that he would be better if he had been taking good care of himself. However, he suddenly fainted some time ago. After going to the hospital for examination, he knew that it was due to anemia. Today, let me talk about why renal insufficiency is anemia.

Why anemia due to renal insufficiency

First: anemia caused by chronic renal insufficiency belongs to renal anemia, which is related to the deficiency of erythropoietin produced by the kidney. It is suggested that erythropoietin injections be given regularly. In addition, we should check the whole set of anemia to see if there is a lack of iron, folic acid and other substances. These substances are also raw materials for erythropoiesis. If there is a lack, we need to supplement them. Injection of erythropoietin and oral administration of hematopoietic raw materials are the main methods to correct renal anemia.

Second: erythropoietin is mainly produced by glomerular cells and medullary stromal cells. Increased destruction of red blood cells: in uremia, hyperpolyaminemia leads to shortened life span of red blood cells and autolysis. In uremia, red blood cell metabolism disorder and increased fragility lead to autolysis of red blood cells. Microvascular disease leads to destruction of red blood cells due to mechanical damage and hypersplenism. Red blood cell loss increased.

Third * the life span of red blood cells is shortened by the influence of the metabolites of retention. Anemia is the most common complication of chronic renal failure, because long-term malnutrition is also an important cause of anemia. Because patients need to control their diet for a long time, they should strictly limit the intake of fat and protein, which are essential raw materials for erythropoiesis. The lack of these two raw materials will inevitably reduce the number of erythropoiesis and eventually lead to anemia.

matters needing attention
