Do not worry for their babies physiological anemia

Anemia in a wide range of
Many diseases can be manifested as symptoms of anemia, such as bleeding ulcer disease, leukemia and other serious hookworm disease, which are pathological anemia. There is a physiological anemia, that is to say that the growth and development of mankind anemia appeared in the process of a biological phenomenon. The main performance of the baby after 1-8 weeks within, also known as “baby physiological anemia.”

Newborn babies hemoglobin can be as high as 150-230 grams / liter, erythrocyte count up to 5-7 × 1012 / +11. After birth 1-8 weeks with hemoglobin can be gradually decreased to below normal until eight weeks after the end, the general said such anemia living rational anemia. Full-term infants decreased hemoglobin physiological little lower than 100 g / liter; premature infants because of the lower respiratory function and metabolism, weight fast growth, physical appearance as early as anemia, anemia performance was even more serious after birth 3-6 weeks can be reduced to 70-90 grams / liter. Why should there be baby physiological anemia? The main reasons were:

(1) Children born after the establishment of a pulmonary respiration, arterial oxygen saturation from 45% to 95%, the function of bone marrow-made red blood cells decreased erythropoietin by the high level of fetal reduced to very low levels, erythrocyte hyperplasia obvious reduce.

(2) of the red blood cells of fetal hemoglobin short life, children born after the massive destruction.

(3) after birth three months weight in children is the fastest-growing stage, the rapid expansion of blood volume, red blood cell diluted. Physiological anemia in infants, generally without treatment, parents also need not be too tight, normal baby eight weeks after the hemoglobin dropped to 100-110 grams / liter, serum erythropoietin concentration increased once again stimulate bone marrow, bone marrow blood began to restore its normal function, because of anemia and physical decline in hemoglobin can be back to normal. Iron deficiency anemia in children from the common cause of iron deficiency anemia is a common disease in children, due to lack of necessary hematopoietic iron resulting in anemia, and more in six months-3-year-old infants, the incidence rate was 20% -40 %. Why infants will iron deficiency anemia?

1, inadequate intake of maternal fetal obtained from the last three months of iron up. In normal neonatal iron content per kg body weight 70 mg for Health after four months of use. Once the iron storage exhausted, it must be from the diet, children still eat at this time or breast milk, which is low in iron, 100 grams of breast milk or iron in the rate of only 10 percent and could not meet the needs of growth, So from four months beginning with supplementary food, especially those high iron content Fresh such as egg yolks, liver, such as mud.

2, excessively rapid growth in infants germinal dedicating ourselves quickly, the physiological requirements of iron also increased, full-term infants long to Zhou Gang, newborn weight has increased to the three times, circulating bad suction portability of the hemoglobin increased by 2 times . Because of the growth of literacy and fast, and deep blood volume increased iron requirement has also increased.

3, iron loss of chronic excessive blood loss, such as hook disease, intestinal polyps, anal fissure bleeding, although these diseases daily blood loss of water, but all year long, the loss of the iron on when impressive.

4, for other reasons, if the long-term infants, such as diarrhea, chronic diseases can also cause adverse iron absorption; recurrent chronic infection, caused loss of appetite, and the inadequate supply of iron absorption barriers, but also in favor of iron deficiency anemia.
