Generally , adult male hemoglobin concentration is 120-160g/L, adult female is 110-150g/L, higher than the normal range is high hemoglobin.

There are two mian reasons would cause high hemoglobin concentration:
First, the hemoglobin concentration is high due to hemoconcentration, the most common is due to a lot of dehydration, such as severe diarrhea, vomiting, or a lot of sweating after the blood volume decreases, blood concentration, red blood cells The density increases and the hemoglobin concentration is higher.
Second, it is caused by an absolute increase in the number of red blood cells. Common chronic hypoxic diseases, such as chronic obstructive pulmonary disease, congenital cyanotic heart disease, etc., will increase the number of red blood cells due to hypoxia, and eventually cause hemoglobin concentration deviation high. In myeloproliferative diseases such as essential thrombocythemia and polycythemia vera, the hemoglobin concentration will also be significantly higher due to the abnormal increase in the number of red blood cell.
