Renal anemia is a kind of disease which is caused by low count of red blood cells in blood. This type of anemia is caused by a lack of erythropoietin, a hormone produced in the kidneys that helps to create red blood cells. For CKD patients, the worse the kidney is, the severer the anemia will be.

How does CKD cause renal anemia?

1 Insufficiency of EPO (Erythropoietin):

EPO is essential in the formation of red blood cells, and the shortage of EPO is the main cause of renal anemia. It is generated by our kidney, so when kidneys are damaged, the production of EPO will decrease. When this happens, the patients run a high risk for renal anemia.

2 Short life span of red blood cells

The main function of kidney is to filter wastes in our body, when in renal failure stage, a large amount of toxin accumulates in the body, hence interfere the creation and metabolism of red blood cells. This may shorten the life of red blood cells and then cause renal anemia.

3 The decreases of red blood cells

CKD patients in stage 3 or 4 have blood urine which is diagnosed when large amounts of red blood cells leak into urine. Without timely and effective treatment, more and more red blood cells leak into urine, leading to the decrease of red blood cell in blood. Another reason is bleeding. Bleeding conditions like gums bleeding and epistaxis occur when illness condition runs to a certain stage. This also contributes to the occurrence of anemia.

4 Malnutrition

We all know that CKD patients have special diets because they must be alert about the elements in foods, so as to avoid aggravating the disease. And many patients have to limit the intake of protein. Protein is the main raw material for blood and when protein in blood is decreased greatly, anemia occurs.
