What reason is hemoglobin concentration on the high side

summary

Why is the average hemoglobin concentration on the high side? When some people have a physical examination, the doctor tells them that the average hemoglobin concentration is on the high side. Generally, they don't know why. Now I'll talk about the high average hemoglobin concentration. I'll tell you the reasons for this situation. I hope it can help you.

What reason is hemoglobin concentration on the high side

Reason 1: first of all, if the hemoglobin is slightly increased, the increase range is less than 10g / L, it is generally considered insignificant. If there are no obvious symptoms, there is no need for special treatment.

Second, the normal value of MCH is 27-31pg. The reasons for high average hemoglobin are as follows: physiological increase: the red blood cells and hemoglobin of residents living in plateau areas are often higher than those living in plain areas. Drinking too little water or sweating too much, removing too much water can lead to temporary blood concentration, resulting in a slight increase in red blood cells and hemoglobin. The newborn is increased physiologically.

The third reason: the last is pathological elevation: severe vomiting, diarrhea, sweating, large area burn patients, diabetes insipidus, hyperthyroidism crisis, diabetes acidosis, etc. due to excessive water loss in the plasma, resulting in blood concentration, there will be a significant increase in the amount of red blood cells and red blood protein. Chronic heart disease, pulmonary heart disease, cyanotic congenital heart disease and so on, because of tissue hypoxia, the amount of erythropoietin in the blood increases, which makes the amount of red blood cells and hemoglobin in the blood compensatory increase.

matters needing attention

High average hemoglobin concentration may be caused by hypoxia in high altitude areas. In addition, smoking, chronic bronchitis and heart diseases may all lead to high average hemoglobin concentration. The average hemoglobin concentration is normal or high, indicating that the body is rich in iron, and no need to supplement iron. The average hemoglobin content is high, generally not much clinical significance, but if the iron content is high, it may also cause coronary atherosclerosis and other cardiovascular diseases. At this time, we should pay more attention to diet, and try to reduce the intake of high calorie and high iron food.
