what makes hemoglobin elevated
A high hemoglobin level for a man would be above 18 g/dl and a woman 15 g/dl. If your hemoglobin is below those levels and above the average, then there is likely no problem. High hemoglobin levels can occur naturally if you live or have traveled recently to high altitudes where oxygen levels are low. The low oxygen stimulates your body to produce more red blood cells which have the hemoglobin.
