High hemoglobin needs to be treated with rehydration, electrolyte supplementation, and treatment of the original disease according to the cause of the disease. The normal values of hemoglobin are 120-160g/L for men, 110-150g/L for women, and 180-190g/L for newborns.There are relative and absolute elevations of high hemoglobin. The details are as follows: 1. Relative elevation is seen in profuse sweating, repeated diarrhea, continuous vomiting, extensive burns, and uremia. This type of elevation is caused by a decrease in blood volume, and treatment requires correction of the cause of the disease, which can include rehydration and electrolyte replacement. 2. Absolute elevation can be physiologic or pathologic. Physiologic elevation is seen in some special groups, such as newborns, mountain climbers, residents of high mountain areas, etc., and generally does not require treatment. Pathological see obstructive emphysema, pulmonary heart disease, congenital heart disease and other cardiopulmonary diseases, and some tumor diseases, true erythrocytosis, need to actively treat the primary disease to correct. Cardiopulmonary diseases can be treated with bronchodilators (beta agonists, glucocorticoids, etc.), vasodilators (phentolamine, theophylline, etc.) and oxygen therapy. True erythrocytosis can be treated with cytostatic therapy (hydroxyurea, interferon, etc.) and anticoagulant drugs (aspirin, etc.). Oncologic diseases are selected with approaches such as surgery, radiotherapy, and chemotherapy. When there is a high hemoglobin, you need to go to the hematology department of the hospital to do a systematic examination, early diagnosis and early treatment, the choice of drugs and the method of taking them should be under the guidance of professional doctors.
