High total hemoglobin mainly includes physiological factors and pathological factors.
1. Physiological factors: after strenuous exercise, the body’s oxygen demand increases, at this time the body needs to compensate for the increase in hemoglobin concentration in order to maintain the body’s need for oxygen, hemoglobin may appear to be mildly elevated.
Part of the population living in the plateau area, due to the high altitude, long-term hypoxia, the body in order to maintain the body’s normal oxygen supply, will be compensatory to promote the proliferation of red blood cells, increase hemoglobin, improve the oxygen-carrying capacity.
2. Pathological factors: some patients suffering from erythrocytosis, diarrhea and other diseases will have elevated hemoglobin, such as erythrocytosis patients due to the abnormal proliferation of bone marrow, there will be elevated hemoglobin phenomenon. In patients with severe diarrhea, a large amount of their own body fluids are lost with the diarrhea, which leads to the concentration of the body’s blood and elevated hemoglobin.
High total hemoglobin requires prompt medical attention and a clear diagnosis under the guidance of a physician to avoid delays.
