Is the high average hemoglobin concentration serious

Whether the high average hemoglobin concentration is severe or not needs to be judged based on specific values and causes. In most cases, a slight increase does not require excessive concern, but persistent abnormalities may indicate blood concentration or myeloproliferative disorders.

Blood concentration is a common cause of elevated levels of this indicator, commonly found in people who are dehydrated, after intense exercise, or living at high altitudes. In this case, hemoglobin concentration will gradually return to normal with fluid supplementation or environmental adaptation, and usually will not be accompanied by other abnormal symptoms. Long term smokers may also experience a false increase in test values due to the binding of carbon monoxide to hemoglobin, which can decrease after improving their lifestyle habits. The use of certain drugs such as erythropoietin may interfere with the test results, but after discontinuation, the indicators often recover on their own. When the hemoglobin concentration continues to exceed 185g/L, it is necessary to be alert to pathological factors. Polycythemia vera can lead to abnormal proliferation of bone marrow, and patients may experience symptoms such as dizziness and skin itching, which need to be diagnosed through bone marrow puncture. Chronic obstructive pulmonary disease is often accompanied by coughing, difficulty breathing, and other symptoms due to long-term hypoxia that stimulates red blood cell production. Some kidney tumors secrete erythropoietin, which can also cause secondary elevation and need to be differentiated by imaging examination. Patients with congenital heart disease may experience compensatory elevation due to insufficient blood oxygen saturation.

If abnormal indicators are found, it is recommended to recheck the blood routine and complete tests for iron metabolism, vitamin B12, etc. In daily life, it is recommended to maintain a daily water intake of 1500-2000 milliliters and avoid prolonged high-temperature work. Residents in high-altitude areas can regularly monitor their blood oxygen saturation, and smokers should gradually reduce their smoking volume. If accompanied by symptoms such as headache, blurred vision, or continuous increase in numerical values, it is necessary to promptly go to the hematology department for bone marrow examination. When pregnant women have abnormal indicators, the influence of gestational hypertension should be ruled out, and children should pay attention to the possibility of hereditary hemoglobinopathy.
