What is the norm of hemoglobin in the blood of men and women?

Hemoglobin is a complex protein that contains tetravalent iron. It is the atoms of iron that give the blood a red color. It is known that hemoglobin performs a special function - it transfers oxygen molecules to all cells of our body. Therefore, it is very important to monitor how much of this important protein is contained in the blood, as the lack of oxygen carries serious disruptions in the functioning of the human body. With low hemoglobin , anemia can develop. Dizziness, shortness of breath, malfunctioning of the intestine, a sense of fatigue - this is a small list of those disorders that can lie in wait for a person. What is the norm of hemoglobin in the blood of men, and not only? The norm of hemoglobin in the blood is a certain range of the number of this protein, in which the human body functions normally. This indicator depends directly on age and sex.

Norms of blood indices in children

Normal indicators of hemoglobin in the blood of children at each stage of their growth, are different figures. The highest level of hemoglobin is observed in newborns - 145-225 g / l. By the year of life, this indicator significantly changes, and as the child grows, the number of red blood cells approaches the norms of an adult. Lack of hemoglobin in children entails serious consequences, up to the delay of the child's mental development.

The norm of hemoglobin in the blood of women

A sufficient indicator of the content of red blood cells in women is the figure 110-150 g / l. Often the amount of hemoglobin is affected by the menstrual cycle, this is due to the loss of a certain amount of blood. Also, the age of a woman plays here. In pregnancy, the amount of hemoglobin decreases, and this is considered normal. This fact is directly related to the physiological changes in the female body. When pregnancy increases the amount of circulating blood, it prevents the production of hemoglobin. In addition, the child consumes part of the iron, which is necessary for the formation of protein.

The norm of hemoglobin in the blood of men

The amount of hemoglobin in men is considered normal, if this figure is in the range of 130-170 g / l. Since throughout life in the male body no significant changes occur, this indicator does not fluctuate as much as in children and in the beautiful half of mankind. The norm of hemoglobin in the blood of a man depends on what lifestyle he leads. So, a man who sports, this level is higher than that of a person who avoids physical exertion. It is known that residents of high mountain regions also have increased indices of this protein. This is explained by the lack of oxygen in the air. As can be seen, the norm of hemoglobin in the blood of men is slightly different than in women's blood. But these factors are affected by many factors. Not always a lowered level of hemoglobin indicates the presence of anemia. Perhaps a person moves a little, then the oxygen consumption decreases, which means that the number of red bodies decreases. It is also worth remembering that a high content of hemoglobin indicates the presence of some serious diseases.
