Causes of high hemoglobin in children

If a child has high hemoglobin, it is particularly easy to cause high altitude hypoxia. Moreover, for newborn babies, they need to adapt to the external environment. If they are not adapted to the environment, they are particularly prone to diarrhea and sweating. Especially for children in plateau areas, they must pay attention to the hemoglobin value. A high hemoglobin value is life-threatening. So what is the reason for the high hemoglobin level in children?

1. Causes of high hemoglobin

1. If you live in plateau areas, your hemoglobin level will be high. Because of the lack of oxygen in the plateau, tissue hypoxia and hematopoiesis occur, resulting in high hemoglobin levels.

2. Newborn babies generally have high hemoglobin levels (newborns need to adapt to the new external environment and need 2 to 3 weeks of physiological adjustments, during which special physiological conditions appear, such as jaundice).

3. When you are emotionally excited, it is easy to cause a temporary increase in hemoglobin.

4. If the patient's blood is concentrated, the hemoglobin level will be high and the red blood cells will increase, such as strenuous exercise, severe diarrhea, and heavy sweating.

5. Pathological causes of high hemoglobin

1) Some patients with congenital heart and lung diseases will have high hemoglobin (such as tetralogy of Fallot, cyanotic congenital heart disease, obstructive pulmonary emphysema, cor pulmonale) because the compensatory increase of erythropoietin in the body causes high hemoglobin.

2) Certain tumor diseases can cause high hemoglobin (such as renal cancer, hepatocellular carcinoma, uterine fibroids, ovarian cancer, renal embryonal carcinoma, etc.), and erythropoietin increases non-compensatoryly, leading to the above results.

3) Polycythemia vera causes high hemoglobin. It is a blood disease of unknown cause characterized by an increase in red blood cells.

4) If you suffer from diabetes insipidus, hyperthyroidism, or diabetic acidosis, your hemoglobin level will be high.

2. Dangers of high hemoglobin

(1) Severe vomiting, diarrhea, heavy sweating, patients with extensive burns, diabetes insipidus, hyperthyroidism crisis, diabetic acidosis, etc., due to excessive loss of water in the plasma, the blood is concentrated, and there will be a significant increase in the amount of red blood cells and hemoglobin.

Severe vomiting, diarrhea

(2) 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.

(3) Certain tumors, such as renal cancer, hepatocellular carcinoma, uterine fibroids, ovarian cancer, and renal embryonal carcinoma, can also cause a non-compensatory increase in erythropoietin, leading to the above results.

(4) Polycythemia vera is a blood disease of unknown cause characterized by an increase in red blood cells.

No matter what the cause of high hemoglobin, it is harmful to the body. If high hemoglobin is found in liver function tests, you should go to a regular liver disease hospital for a more detailed examination, find the cause, and receive symptomatic treatment.
