What should be hemoglobin?
The concept of "hemoglobin level in the blood" is familiar to every adult. But for all this level is different, because it all depends on age, gender and disease available. Consider in this article what should be hemoglobin in adult men and women, as well as in newborn children and older children.
The main function of hemoglobin is to supply oxygen to all organs and tissues of the body, since without it is impossible to carry out all the vital processes. Therefore, it is desirable that the hemoglobin level is always normal. This can be determined with the help of a simple blood test, “from the finger,” using Sali’s hemometer, the measure of measurement is the number of grams per liter of blood. Accurate diagnosis after this analysis is not set, but it is quite possible to determine the potential shift in the body’s work. Results are compared with the standard, the excess of which is rare, mainly recorded cases of reduction.
Deviations from the norm
An increase in hemoglobin can be an indicator of such diseases:
- Congenital heart defect
- Intestinal obstruction
- Pulmonary fibrosis
- Increased blood density
It also indicates the presence of diabetes and iron deficiency in the blood. In addition, the level may increase due to the large physical load of the person or the flight that he had suffered, and even simply after a long walk in the fresh air. But there are people with constantly elevated levels of hemoglobin - these are residents of highland areas and those who are engaged in mountaineering.
Reduced hemoglobin, or anemia, occurs when hemoglobin is lost during bleeding, blood transfusions and hematological diseases, as well as food deficiency, chemotherapy, and kidney failure.
Hemoglobin in children
For children, the determining factor will be age. The highest level is in newborns, up to 220 g / l., Which is associated with a high oxygen demand of the fetus. Then the level gradually falls, and by the first month hemoglobin should be established in the range of 100-180 g / l. But from the second month hemoglobin fluctuates, the norm in children will vary from 90 to 110 g / l.
- Up to 6 months - 95-135
- Up to 1 year - 100-140
- Up to 2 years - 105-145
- Up to 6 years - 110-150
- Till 12 years - 115-150
- Up to 15 years - 115-155
- Up to 18 years old - 120-160
Prevention of anemia for children is a rich diet, necessarily including meat products and fruits, becauseiron is better absorbed if its use is combined with products rich in vitamin C.
If diagnosed, then only iron supplements prescribed by a doctor can help cure anemia.
Hemoglobin in women
The hemoglobin rate in women is 120-160 g / l. But it is necessary to take into account the menstrual cycle, as well as hormonal changes, especially noticeable in pregnant women. For them, this rate is lower - 110-130 g / l., Because during this period blood circulates faster, and hemoglobin is produced in the same way as before. But iron deficiency can lead to fetal growth or premature birth, therefore, consumption of meat, eggs, fish, pomegranate juice, black bread, nuts should be mandatory for a pregnant woman, and the time for sleeping and staying in fresh air should be increased.
Hemoglobin in men
For men, the level of hemoglobin should be higher than that of women: 130-170 g / l .. This is due to the fact that the rate of hemoglobin in men depends on the presence of testosterone, the male hormone. In addition, the male body is experiencing more physical exertion, which means that its tissues require more oxygen.
