The norm of hemoglobin in the blood: what you need to know about it
On the role of hemoglobin in human bloodsaid a lot. But the main thing is that, in its essence, it provides transportation of oxygen to all organs of the body, thereby providing the necessary level of metabolism.
The norm of hemoglobin in the blood is ambiguousan indicator that depends not only on the person's sex, but also on his age, and also on the environmental conditions. In medicine, there is a certain degree of hemoglobin: hemoglobin in men, in women, in children. For men, the highest range is established, ranging from 130 g / l to 170 g / l. For the female body, this level can be at least 120 g / l and a maximum of 160 g / l. These are general indicators. But when interpreting the result, it is not enough for the doctor to know only the sex of the patient.
Special position
Interpretation of the result of the analysis depends not only on the sex of the patient. The norm of hemoglobin in the blood in certain groups of patients varies depending on the physiological characteristics and age.
The norm of hemoglobin during the bearing of the child. Throughout all three trimesters of pregnancy, doctors track this indicator in the blood of a pregnant woman. In this case, it decreases by 10 units, ranging from 110 g / l to 150 g / l.
The norm of hemoglobin in the blood of people living inhigh mountains, subject to high physical stress and pressure changes, is also subject to change and is from 150 to 170 g / l. Such a significant reduction in the range is an indicator of potential diseases and should be monitored by the attending physician.
On special control of doctors is hemoglobinchildren. The norm varies depending on the age of the child, and a deviation from it can indicate a violation of physical or mental development. The most approximate to the standard "adult" norms is the level of this indicator in the blood of adolescents from sixteen to eighteen years of age. But hemoglobin in newborns differs significantly, ranging from 145 g / l to 225 g / l. The first week of a child's life is characterized by a decrease in its level by 10 units, and by the end of the second week it fits into the framework of 125 g / l-205 g / l.
During the year the parents and the doctor are obligedmonitor the dynamics of hemoglobin in children. The rate for this period varies as follows: the first month - 100 g / l / -180 g / l, the second month - from 90 g / l to 140 g / l, from three to six months - from 95 g / l to 135 g / l, and the second half of the first year of life is characterized by indicators from 100 g / l to 140 g / l. In subsequent periods, the hemoglobin values gradually equalize in accordance with the "adults" characteristic of the given place of residence.
Deviation from the norm.
The norm of hemoglobin in the blood is an indicator of the patient's physical health, so a deviation from it towards a decrease or increase indicates a serious illness.
Lowering the hemoglobin level characterizespresence of anemia and severe blood loss. Both cases require medical intervention with examination of the body. It should be remembered that a decrease in the hemoglobin level in women can be observed with profuse menstruation, which means that the result of the analysis carried out during this period is not very informative. In addition, special attention should be paid to lowered hemoglobin in newborns. As a rule, it indicates the problems of intrauterine development and requires a complete examination of the newborn and subsequent follow-up.
But even higher hemoglobinis a positive factor in the functioning of the body. Typically, this indicates that the patient is exposed to excessive physical exertion, receives an excessive amount of iron, or there is a lesion of an important organ (eg, heart disease or intestinal insufficiency). Therefore, in case of an increase in the hemoglobin index, a fuller examination of the organism is also required.
