High hemoglobin concentration needs to be identified and treated for the cause. If it is caused by true erythrocytosis, you can take hydroxyurea, aspirin and other treatments. If it is caused by poor cardiopulmonary function, you can use doxophylline to dilate the bronchial tubes, diuretics to improve the symptoms of heart failure, if there is a history of hypertension, use antihypertensive drugs to treat the symptoms. 1. True erythrocytosis: true erythrocytosis is a kind of myeloproliferative tumor with abnormal proliferation of red blood cells. Clinical manifestations are absolute increase of red blood cells and hemoglobin, and increase of blood viscosity. Treatment can be oral aspirin to prevent thrombosis, hydroxyurea to inhibit cellular DNA synthesis, interfere with cell production and so on. 2. Poor cardiopulmonary function leads to: chronic obstructive pulmonary disease, chronic pulmonary heart disease, etc. will make the patient’s gas exchange is reduced, the body compensates for the relative increase in erythrocytes and hemoglobin, at this time, you can use doxophylline to dilate the bronchial tubes, diuretics to improve the symptoms of heart failure, if there is a history of hypertension use of enalapril, nifedipine, valsartan, and other antihypertensive drugs for symptomatic treatment. Found that the hemoglobin concentration is high, may also be to the plateau area people, generally do not need treatment. Therefore, it is recommended to go to the regular hospital for systematic examination, comprehensive evaluation and then take medication according to the doctor’s recommendations. Do not take drugs on your own, so as not to cause irreversible damage to the organism.
