The causes of high red blood cell count include blood concentration, physiological elevation, and true erythrocytosis.
When severe nausea and vomiting, diarrhea, burns, scalds and other diseases occur in the human body, which can lead to a large amount of water loss in the body, it will cause blood concentration, then check the blood routine may appear high red blood cell count, to be actively rehydration treatment can be restored to normal.
When people live in a low oxygen environment for a long time (for example, in the plateau area), in order to ensure that the body’s tissues and organs are supplied with sufficient oxygen, the red blood cell count in the blood will physiologically rise, so that the hemoglobin in the red blood cells can be combined with sufficient oxygen for the tissues and organs to use. In this group of people, routine blood tests show high red blood cells and high hemoglobin.
When human beings develop myeloproliferative tumors such as true erythrocytosis and essential thrombocythemia, the bone marrow produces abnormally increased red blood cells, and routine blood tests show that the red blood cell counts and hemoglobin are obviously elevated, and the elevation is progressive.
It is recommended that patients with high red blood cell counts should consult the hematology department in time to complete the relevant examinations to identify the specific cause of the disease and then treat the cause.
