Hemoglobin 175g/L is usually not serious, but if the index continues to rise, it is more serious. 1. Hemoglobin 175g/L is not within the normal range. The hemoglobin of male population is usually between 120~160g/L, and the hemoglobin of female population is usually between 110~150g/L. Hemoglobin 175g/L is not serious for the time being and can be followed up for observation. 2. However, if the index continues to rise, it is more serious, which can be seen in true erythrocytosis, secondary erythrocytosis, etc. For example, patients with chronic obstructive pulmonary disease are in a state of hypoxia for a long time, and the bone marrow hematopoiesis will be reactive stimulation, resulting in secondary erythrocytosis. You should consult a regular hospital in time to find out the cause and standardize the treatment in order to avoid adverse consequences.
