What is the reason for high red blood cells and hemoglobin

The relationship between red blood cells and hemoglobin is mutual. Hemoglobin is an important component of red blood cells. Many people want to know the reason why red blood cells and hemoglobin are high. It may be a relative increase in red blood cells, or it may be related to physiological increase.

1. Relative increase in red blood cells

One is a relative increase, caused by a decrease in blood volume, which is seen in large-area burns, severe dehydration, and chronic adrenocortical insufficiency. Another is secondary polycythemia, which is seen in chronic hypoxia, lung disease, cyanotic congenital heart disease, chronic rheumatic valvular heart disease, etc. It can also be seen in kidney diseases such as renal cysts, renal artery stenosis, various tumors such as liver cancer, lung cancer, and uterine leiomyoma. There is also true polycythemia, which is a myeloproliferative disease. The blood viscosity of this disease is very high, 5-8 times that of normal people, the red blood cell count can reach (6-10)*1 (0 to the 12th power), and the hemoglobin can be as high as 170-240 grams/liter.

2. Physiological increase of hemoglobin

Plateau residents, fetuses and newborns, strenuous labor, fear, cold water baths, etc.; pathological increase is seen in severe congenital and acquired cardiopulmonary diseases and vascular malformations such as tetralogy of Fallot, cyanotic congenital heart disease, obstructive pulmonary emphysema, cor pulmonale, pulmonary arteriovenous fistula, and abnormal hemoglobin disease with low oxygen-carrying capacity. In order to improve and prevent the increase of hemoglobin, you should develop good habits, such as drinking soup before meals to promote digestion, eating more cold food, swimming more, can maintain the balance of body heat, eating more bitter food, can relieve the feeling of fatigue, eating some lettuce in winter can promote the operation of metabolism, and drinking a glass of water every morning when you get up.

3. Others

Under normal circumstances, the production and destruction of red blood cells are in a dynamic balance, so the quantity and quality of red blood cells in the blood remain relatively stable. Regardless of the cause, the abnormal production and destruction of red blood cells will cause changes in the quantity or quality of red blood cells, leading to the occurrence of diseases.
