The causes of iron deficiency anemia in children are related to the insufficient iron reserves in the body. The baby in the fetal period, mainly from the mother’s iron, especially in the last three months of pregnancy get the most iron.
these iron reserves can meet the baby’s growth and development needs in 4-6 months after birth. However, if the pregnant mother has severe iron deficiency anemia during pregnancy, the “iron reserve” that she can provide for the baby is very limited. In addition, some premature babies who miss the peak of iron reserves in the last three months of pregnancy are more likely to develop anemia after birth than other full-term newborns.
second, the baby’s growth and development speed is too fast, which is also a reason for the baby’s anemia. The first six months after birth is the first peak stage of growth and development. Generally, the body weight of a baby in three months after birth is twice of its birth weight, and its weight at one year old is three times of its birth weight. At this stage, if the nutrition can’t keep up, and iron rich food is not added in time, then iron deficiency anemia will occur easily.
third, iron deficiency anemia occurs in childhood and adolescence, which is common in children who are partial and picky. In addition, some long-term chronic bleeding diseases, such as hookworm disease, intestinal polyps, chronic diarrhea, repeated infection, can also be caused by excessive iron loss or consumption and anemia.
generally speaking, iron deficiency anemia can receive better effect after iron treatment. But in addition to iron deficiency anemia, anemia in children may also be caused by other reasons.
folic acid, namely vitamin B9, has the effect of preventing fetal neural tube malformation and is commonly used in pregnant women and pregnant women. In fact, everyone needs this kind of vitamin. The equivalent amount of folic acid we need to eat every day is 400ug. When folic acid is insufficient in the body, it can hinder the synthesis of hemoglobin and make the red blood cells abnormal. It is megaloblastic anemia. Clinically, it is characterized by pale complexion, decreased appetite, listlessness, fatigue, gastrointestinal dysfunction and other symptoms.
when vitamin B12 is deficient in the body, our body will be anemic because it cannot produce enough healthy red blood cells. This is a large cell anemia, with folic acid deficiency caused by anemia, belong to nutritional megaloblastic anemia. When there are not enough red blood cells in the body, the body will not be able to get the oxygen it needs. This time, it often shows fatigue, weakness and shortness of breath.
thalassemia is an autosomal recessive blood disease with a family history. It is due to the deficiency of globin gene that one or more of the globin peptide chains in hemoglobin are reduced or can not be synthesized, resulting in changes in the composition of hemoglobin, thus causing chronic hemolytic anemia. The common types are α – thalassemia and β – thalassemia Type.
if mild thalassemia does not have obvious anemia symptoms, it generally does not need special blood therapy. However, if it is mild thalassemia combined with iron deficiency anemia, in order to prevent the aggravation of anemia, it is necessary to pay attention to the intake of various meat foods in daily life, and eat iron rich foods such as pig liver, pig blood, duck blood once or twice a week.
moderate to severe thalassemia, due to chronic hemolysis has caused excessive iron load in the main organs of the body, so it is not suitable for such patients to supplement iron, but iron supplement will aggravate, which is counterproductive.
in some patients, due to the lack of various enzymes and coenzymes related to heme synthesis, their activities are reduced and their activities are blocked, resulting in poor utilization of iron and disorder of heme synthesis. As a result, excessive iron reserves in tissues and small cell hypochromic anemia in peripheral blood are formed. Most of these anemia children have splenomegaly, and iron treatment is ineffective. Some patients are effective in vitamin treatment and can be taken orally Vitamin B6, effective need long-term treatment.
anemia caused by infectious diseases is caused by many pathogenic microorganisms invading the human body, which can reduce the production of red blood cells, increase damage or blood loss in the process of inflammation or infection. Mainly divided into two categories, one is the rapid occurrence of infection, often with acute hemolytic anemia performance, can cause the sclera, skin color yellow and other jaundice performance.
the other type is chronic disease anemia, which occurs gradually during chronic infection or inflammation. It is often manifested as mild skin and mucous membrane pale, palpitation, chest tightness, shortness of breath and loss of appetite. For the anemia caused by infectious diseases, after active anti infection treatment, the primary disease is under control, and the patient’s blood picture can quickly return to normal.
when the fetus is in utero, the blood oxygen saturation is low, and the content of serum erythropoietin and erythropoietin are increased. After birth, with the establishment of baby’s spontaneous breathing, the blood oxygen content increases, the erythropoietin decreases, and the number of red blood cells and hemoglobin gradually decreases. Therefore, the hemoglobin of full-term infants usually drops to 95-110g / L at 6-12 weeks after birth, and premature infants 4- It decreased to 65-90 g / L at 8 weeks.
However, when the hemoglobin concentration drops to a certain amount, it can stimulate the production of erythropoietin, restore the hematopoietic activity of bone marrow, and slowly increase the number of red blood cells and hemoglobin, and then correct the anemia. Therefore, for this stage of physiological anemia, there is no need for special treatment, which is a phenomenon of adjustment of the baby to environmental changes It’s not real anemia.
in a word, when the baby has anemia, it is better to cooperate with the doctor to find out the causes and basic diseases of anemia, and take corresponding measures to remove the causes, so as to better correct the baby’s anemia. #Media super group of Medical Federation#
