fixation of iron by macrophages in certain pathological processes.increased costs of iron can be in a newborn with chronic diseases or congenital heart disease.violation of iron absorption in a newborn with ulcerative colitis or other pathologies.
The main causes of low hemoglobin development in newborns are as follows: Reduces the absorption of iron when eating milk food and strong tea - with iron, iron forms insoluble albumins, with tannin also forms insoluble complexes. Improves absorption of iron at a sufficient content in the diet of mother protein, ascorbic acid. The absorption of iron affects the composition of the food of the pregnant woman and in the future of the nursing mother. So, the absorption of iron increases after blood loss due to operations in newborns. Absorption increases when there is even a latent, latent iron deficiency and decreases when iron stores reach the norm. There is a specific mechanism for regulating iron absorption. In cells of the intestinal mucosa, iron forms a complex with the protein - apoferritin, and then passes into ferritin, from which iron is separated in the form of a divalent, enters the blood, binds to transferrin, which carries iron to places of use or deposition. This process is carried out in the stomach in the presence of hydrochloric acid. The condition for its assimilation is the transition of trivalent iron into a bivalent one, that is, into a soluble reduced form. In foods, iron is predominantly in the trivalent form. Assimilation is provided by enzymes and biologically active substances that are in the duodenum and in the initial section of the small intestine. To maintain iron stores at the physiological level, it is necessary to ensure the intake of at least 1-2 mg of iron every day.
What causes low hematocrit and hemoglobin skin#
Iron from the child's body is constantly excreted with sweat, urine, depleted cells of integumentary tissues - skin and mucous membrane of the digestive tract. The exchange of iron is closely related to the processes of its intake and excretion from the body. Stocks of iron are created during fetal development of the fetus mainly at the expense of the maternal fund, and later accumulate by absorption of iron from food. The main mass - about 2/3 of its total amount - is part of hemoglobin, 200-300 mg - in the composition of cytochromes and cytochrome oxidase, myoglobin from 100 to 1000 mg of iron is deposited in the liver, bone marrow, spleen in the form of ferritin and hemosiderin.
From this, the main causes of the development of low hemoglobin come out. There are different types of deficient conditions, which include iron deficiency, deficiency of folic acid and B12 acid, as well as hemolytic conditions. The level of hemoglobin can decrease during the so-called deficient states, when the formation of hemoglobin is violated or there is its excessive destruction. Therefore, a hemoglobin level of less than 180 is considered to be low. These are the normative values for the child during the first month of life. Therefore, the content of hemoglobin in the body of a newborn child is 180-220 grams per liter. It is able to attach more oxygen than regular hemoglobin, which allows the entire body of the baby to provide enough oxygen. Hemoglobin is called "fetal", and its functionality is slightly higher. Therefore, hemoglobin in a child who is in utero is not the same as in adults. This necessitates that the blood cells work more efficiently. Features of the circulatory system of the child at a time when it develops in the mother in the abdomen is that only a large circle of blood circulation works. To understand what indicators for a newborn are considered to be lower, one should know about the norms of hemoglobin in a newborn.
