What are the reasons for high hemoglobin

Hemoglobin is the main component of red blood cells. The normal value of hemoglobin is also related to people's physical condition. There are many reasons for high hemoglobin. In addition to physiological increase, pathological increase may also occur, and these may be related to disease.

1. Relative increase:

Due to some reasons, water is lost in plasma, the blood is concentrated, and the content of red blood cells and hemoglobin increases relatively. Such as drinking less water, sweating a lot, etc. Due to some reasons, water is lost in plasma, the blood is concentrated, and the content of red blood cells and hemoglobin increases relatively. Such as continuous severe vomiting, large-area burns, severe diarrhea, heavy sweating, etc.; also seen in chronic adrenal insufficiency, diabetes insipidus, hyperthyroidism, etc.

2. Physiological increase:

Such as strenuous labor, fear, cold water showers, plateau residents, etc.

3. Pathological increase:

Congenital heart disease, obstructive pulmonary emphysema, cor pulmonale, pulmonary arteriovenous fistula, and abnormal hemoglobin disease with low oxygen-carrying capacity, etc. Don't worry too much, you can check your blood routine again when your physical condition is relatively normal (no obvious dehydration, avoid sweating, etc.) to verify the test results.

4. Disease

Chronic heart disease, cor pulmonale, cyanotic congenital heart disease, etc., due to tissue hypoxia, increase of erythropoietin in the blood leads to compensatory increase of red blood cells and hemoglobin in the blood.

5. Tips:

If the hemoglobin level is found to be high during the examination without any discomfort symptoms, the patient only needs to pay attention to diet and exercise properly in daily life. The patient should drink more water and eat more fresh vegetables and fruits, and the symptoms will gradually ease.
