Anemia and Renal Failure

Patients with kidney disease often appear anemia in the early stage of the illness, but almost all of Renal Failure patients suffer from Anemia. Then what causes anemia in Renal Failure? The following gives detailed explanation.

Firstly, let's have a general knowledge of what anemia is.

Anemia means that there is decreased number of red blood cells circulating in the bloodstream, which is usually detected by low blood hemoglobin concentration.
Hemoglobin refers to a kind of iron-rich protein which can carry oxygen from the lungs to all over the human body. Therefore, a consistent shortage of oxygen of the bloodstream will lead to damages in organs like heart, brain, etc.

Secondly, we need to make the causes of anemia in Renal Failure clear.


● Iron deficiency

Besides short supply of EPO, another most common cause of anemia in patients with Renal Failure is iron deficiency. Low iron levels may cause anemia in Renal Failure, because without enough iron, the body is unable to produce enough hemoglobin for red blood cells, so the oxygen supply is not enough, causing anemic

● Lack of erythropoietin (EPO)

Healthy kidneys can produce a hormone, called EPO, which can stimulate the bone marrow to produce enough amount of red blood cells. In Renal Failure, the secretion of EPO is not enough, so severe reduction of red blood cells will occur, causing anemia in patients.

● Other causes

Anemia in patients with Renal Failure can also be caused due to low levels of vitamin B12, low levels of folate, etc.


Currently, dialysis and kidney transplantation are the only two available treatment options for renal failure in western countries. However, the most advanced immunotherapy in Shijiazhuang Kidney Disease Hospital can help patient treat Renal Failure effectively. Some patients with urine output can even get rid of dialysis.
