How does a few months darling anaemia return a responsibility?

summary

Baby anemia refers to a kind of anemia caused by the destruction of red blood cells and the decrease of hemoglobin in the baby after birth, which is a normal physiological phenomenon in the process of growth and development of each baby, so it is called Baby physiological anemia. How does a few months darling anaemia return a responsibility? Let's talk about it.

How does a few months darling anaemia return a responsibility?

First of all, the mother inhales oxygen through the lung breathing movement, and the hemoglobin of the mother's red blood cells carries oxygen to the placenta and transmits it to the fetal red blood cells. However, the oxygen transport capacity of the fetal red blood cell hemoglobin is only half of that of the mother's red blood cell hemoglobin, so the fetal hematopoietic organ must produce more cells and hemoglobin to carry oxygen, To meet the needs of fetal growth and development, so the hemoglobin of the fetus at birth can be as high as 190g / L or more.

After birth, the baby's lung respiratory movement begins, and the oxygen carrying capacity of red blood cells is significantly enhanced. There is no need for so many red blood cells in the fetal period, and the body will "indicate" the bone marrow to reduce the production of red blood cells; At this time, the red blood cells produced in the fetal period also began to destroy; In addition, three months after birth is the fastest growing period of infants, the increase of blood fluid volume is greater than the increase of erythropoiesis, and the original red blood cell concentration is diluted.

The comprehensive result of the above factors is: hemoglobin gradually decreases within 1 week after birth, and generally stops after 8 weeks. Hemoglobin can drop to 90-110g / L from 2 to 3 months after birth. This normal physiological changes caused by the transient state of anemia known as physiological anemia. In the process of hemoglobin decline, the body "indicates" that the bone marrow gradually enhances the ability of hematopoiesis, and the hemoglobin generally returns to the normal level around half year old, reaching 120-160g / L.

matters needing attention

Physiological anemia is a normal phenomenon in the process of infant growth and development, so there is no need to prevent it. Physiological anemia is a normal phenomenon in the process of infant growth and development, so there is no need for treatment. However, it should be noted that the food should be rich in substances needed for hematopoiesis, such as breast-feeding as far as possible, giving formula milk of a certain age, and timely adding foods containing vitamin E, folic acid and iron to premature infants, so as to be beneficial to the recovery of hematopoiesis.
