The symptom of renal anemia is so mild that patients may not feel it. Many patients think that having a good rest is enough when they have the symptoms of fatigue, dizziness, palpitation and shortness of breaths after activities because they do not have much knowledge of renal anemia. What they haven’t realized is that the severe kidney disease is happening to them.
Then what are the reasons for renal anemia? There are mainly three reasons of
Firstly, because of the damage of parenchyma, kidney can not excrete
erythrogenin normally, which greatly influences the hematopoietic function of
Secondly, when the renal function is damaged, the metabolic wastes can not be
discharged out of our body normally so they just stay in the blood. These wastes
can damage red blood cells directly and shorten the life of red blood cells.
Living in such an environment, the red blood cells can not live for a long time.
If one gets transfusion, the undamaged renal parenchyma’s function of
hematopoiesis can also be greatly affected.
Thirdly, the metabolic wastes which stay in the blood circulation can affect
the function of platelet and clotting factors, making patients to bleed more
easily including bleeding of epistaxis, gingivae, stomach and intestine, which
greatly aggravates the anemia.
Besides the above, renal anemia also has relation with the early symptom of
gastrointestinal tract of renal insufficiency because nausea, vomiting and
diarrhoea can make patients malnourished and in turn lead to persistent
