Many pregnant mothers have been diagnosed with iron deficiency anemia during pregnancy, which is a common condition during pregnancy.

An article was published in the "Chinese Journal of Epidemiology", which was a relatively large sample study in Jiangsu Province in 2018. Research results have found that the probability of anemia in our country is about 25%, and the incidence of iron deficiency anemia is also different at different gestational ages. From this result, iron deficiency anemia occurring in the third trimester of pregnancy is about 25%-30%. %, which is considered a relatively high probability. How to replenish blood for anemia during pregnancy? What happens if the fetus is prone to hypoxia?

1. Why are pregnant women prone to iron deficiency anemia after pregnancy?

After pregnancy, a pregnant mother must eat a portion of food to provide nutrition for herself and her fetus at the same time. Especially starting from the second trimester, the intake requirements of many nutrients increase.

According to the "Dietary Reference Intakes of Chinese Residents (DRIs 2013)", the recommended iron intake for pregnant women in early, middle and late pregnancy are 20mg/d, 24mg/d, and 29mg/d respectively. For women preparing for pregnancy before pregnancy, the dosage is 20mg/d per day.

From this recommended data, it can be seen that pregnant women do not need extra iron supplements in the early stages of pregnancy, but after entering the second trimester, they will need 4mg more per day than before, and in the third trimester, they will need 9mg more per day than before. .

Therefore, it is necessary to pay attention to "iron supplementation" from the second trimester of pregnancy and eat more iron-rich foods to prevent iron deficiency anemia.

2. Does anemia in pregnant women affect the fetus? What will happen to the fetus due to hypoxia?

Anemia in pregnant women can also be divided into mild, moderate and moderate. Different anemia conditions of pregnant mothers have different effects on the fetus.

Generally speaking, pregnant women with mild anemia have little impact on the fetus and will not cause fetal anemia, because the fetus will obtain enough iron from the blood of the pregnant mother to synthesize its own hemoglobin.

But if you are a pregnant woman with severe anemia, the blood supply and oxygen supply to the placenta will decrease due to the decrease in the oxygen-carrying capacity of the blood cells in the pregnant woman's blood. Then the fetus will suffer from ischemia and hypoxia. ?Situation of fetal distress.

The book "Dietary Guidelines for Pregnant Women and Wet Nurses" points out that if iron deficiency during pregnancy is not corrected in time, the incidence of mature fetuses and premature infants will increase significantly, and even stillbirth.

There is a more important point: if the iron deficiency in the fetus or infant period is not intervened and caused damage, it may lead to the baby's: reduced IQ, impaired memory, impaired emotional intelligence, and affected physical development. .

3. If anemia is detected during pregnancy, how can pregnant women replenish blood effectively?

If a pregnant mother is found to have iron deficiency anemia during her prenatal check-up, she should correct the "anemic state" as soon as possible.

1. If it is mild anemia, it can be corrected by eating more iron-containing foods.

① First, eat more iron-rich foods.

Such as animal liver (such as pig liver, chicken liver, etc.). In addition, you can also eat animal kidneys, lean meat, beans, kelp, shrimp, jellyfish, seaweed, mushrooms, amaranth, nostoc, and tomatoes. , red dates, cherries, carrots, etc. Animal blood is also rich in iron, but considering the source and hygiene issues, it is best for pregnant mothers to eat selectively.

② Secondly, eat more foods that promote iron absorption and less foods that affect iron absorption. Vitamins help promote iron absorption, especially vitamin C, so you can eat more fruits and vegetables rich in vitamin C, such as fresh dates, oranges, kiwis, etc. Tannic acid, oxalic acid, phosphate and other ingredients in vegetables will affect iron absorption. For example, it is best to blanch spinach and rapeseed before eating to destroy the oxalic acid in them in advance, so as not to affect iron absorption. ③ Eating more high-protein foods also has a good effect on relieving anemia.

In fact, not only during the second trimester, but also during the entire pregnancy, you should eat more protein foods, such as milk, meat, eggs, fish and shrimp, etc., which are rich in animal protein, while beans, sesame, Nuts and other foods are rich in plant protein and can be eaten in moderation.

2. If you have moderate to severe anemia or dietary supplements are not effective, you should take iron supplements.

Generally during pregnancy, if the pregnant mother experiences it on time, severe anemia will not occur. If dietary supplements are not effective for the pregnant mother, or her anemia worsens, the doctor will recommend taking iron supplements.

When taking iron supplements, it should be taken under the guidance of a prenatal doctor. It is not recommended that pregnant mothers buy some iron supplements by themselves. During the period of taking iron supplements, it is necessary to review the hemoglobin once a week to monitor the hemoglobin to see if there is a gradual increase or Back to normal. Iron supplements generally need to be supplemented for 2-3 months. Even if the hemoglobin is normal, iron supplements must be continued to correct the lack of "iron storage in the body" (iron pool). That is, in addition to normalizing the iron in hemoglobin, it is also necessary to Complete the iron in the "Iron Storehouse".
