Due to physiological changes, the metabolism of pregnant women is faster than non -pregnant women, and the need for oxygen needs to increase accordingly.Therefore, the number of red blood cells and hemoglobin in pregnant women is lower than that of pregnant women.In addition, due to the growth of fetal and placenta, the most blood capacity increases with the increase in physiological needs, but more plasma increases in the increased blood than red blood cells, which forms a phenomenon of blood dilution.In fact, the total amount of red blood cells and hematopoietic egg TL in pregnant women will not decrease during pregnancy. This is just a relatively anemia. When hemoglobin is less than 100 grams/liter and higher than 80 grams/liter, it is called physiological anemia.If it is less than 80 grams/liter, it is called pathological anemia.Physiological anemia will increase with the progress of pregnancy. It is significantly significant in the 8-9 months of pregnant women, generally not serious, and return to normal 4 weeks after giving birth.
There are two common anemia for pregnant women, one is iron deficiency anemia, and the other is giant red blood cell anemia.About 25%of pregnant women will suffer from iron deficiency anemia. This is because during pregnancy, the development of fetal and placenta and the increase in uterus have greatly increased, and the demand for iron is 4 times higher than before pregnancy.In addition to physiological factors, if gastric acid secretion of pregnant women decreases or has partial eclipse, insufficient intake of iron -containing foods cannot meet physiological needs, and it can also lead to anemia.The reduction of iron pots is also an important reason for insufficient iron intake. Cooking with iron pots can increase the iron in the food by 10 times, and it is better to be absorbed by the human body.If pregnant women have the most blood loss, or suffer from hemorrhoids, hookworm disease, duodenal ulcer, etc., they will develop into severe anemia.In addition, if pregnant women suffer from anemia before pregnancy, they are likely to increase after pregnancy.
There is a sticky protein called internal factor in the gastric juice of healthy people. It can absorb vitamin B12 in food. Vitamin 2 is an indispensable raw material for red blood cells.If pregnant women have long -term malnutrition and insufficient gastric secretion, adhesive protein will lack, causing vitamin B12 deficiency and affecting the maturity of red blood cells.A decrease, this symptom is called giant red blood cell anemia.
If pregnant women with anemia cannot be treated well before childbirth, they will still be anemia after delivery, which will affect the formation of milk, resulting in a small amount of milk and poor nutrition.
Anemia can also affect the fetus, cause hypoxia in the fetus, and severely causes the weight of the fetus, premature birth, and baby after birth, affecting the development of the fetal brain cells, or because the fetal congenital iron reserves are insufficient and nutritional.anemia.
It can be seen that the anemia is very harmful to pregnant women and fetuses. It should attract the attention of pregnant mothers. During pregnancy, it is necessary to check it regularly.Eat more iron -rich foods.Of course, protein, vitamin B12 and folic acid are also indispensable. Pregnant women should also pay attention to eating in diet, and they can eat more fresh vegetables, fruits and animal proteins.You can consult a doctor and use iron drugs for treatment, such as the cheap and cheap sulfate.
Pregnant women take 5 mg of folic acid every day to prevent giant red blood cell anemia. If there is a disease, it can increase the amount of folic acid, 3 times a day, 5-10 mg once a day.If it is caused by the lack of vitamin B2, 100 mg of vitamin can be injected once a day.If anemia is severe and the due date has been reached, blood transfusion treatment can be performed.
