During pregnancy, why can’t I always eat a lot?

A few days ago, a pregnant mother asked me in the background: I was a little scarn during pregnancy, but I worked hard to eat blood supplement food. I still couldn’t make up. What should I do?

In order to carefully talk about this problem, I also pulled up the attending physician of the clinical nutrition department of Beijing Union Hospital, Dr. He Shuli, to explain the problem of anemia during pregnancy.

Many pregnant mothers definitely want to eat after learning that they have.After all, if you do n’t eat it yourself, your baby should eat it too!

However, because nausea and vomiting can’t be eaten when they are pregnant, they will soon be anemia. When the early pregnancy is reacted early, even if I eat more than usual, the hemoglobin still falls, and the anemia cannot be replenished.

I believe that pregnant mothers with such experience are very distressed!In fact, anemia is a very common phenomenon during pregnancy. Don’t worry too much, there are always solutions!Let’s first understand the anemia during pregnancy!

The most common anemia of pregnant mothers

There are many situations that cause anemia during pregnancy, mainly in the following:

The peak, an average increase of about 1500ml, and maintained this level to childbirth.However, the production of red blood cells in the blood often cannot keep up with the increase in blood capacity, so the blood of pregnant mothers will be diluted and "physiological anemia" will occur.

Iron deficiency anemia: baby baby also needs to make hematopoietic in your body, especially at 20-24 weeks of pregnancy, the demand for iron starts to increase significantly. Once the pregnant mother is insufficient, it will lead to "iron deficiency anemia".Essence

Folic acid deficiency anemia: After pregnancy, the demand for folic acid in the body of the pregnant mother increases from 400 micrograms before pregnancy to 600 micrograms. However, due to the increase in hormones such as progesterone in the body, gastric acid secretion will decrease, gastrointestinal peristalsis will be weakened, and it will not affect things and affects things.The intake and absorption of folic acid will easily occur "folic acid deficiency anemia."

In addition, there are different types of vitamin B12 deficiency anemia, thalassemia, and regenerative disorders, but are relatively rare.

Pregnant mothers are the most common is physiological anemia and iron deficiency anemia. Because sufficient iron is the prerequisite for hemoglobin production, they are almost the same disease to a certain extent.

Prevent iron deficiency before anemia

Although anemia is common, it is small or small for pregnancy.Severe anemia during pregnancy mainly depends on the degree of anemia, and can be diagnosed at a glance at the blood routine.

According to hemoglobin (HB) levels, it is divided into mild anemia (100 ~ 109g/L), moderate anemia (70 ~ 99g/L), severe anemia (40 ~ 69g/L), and extremely severe anemia (<40g/L).

Severe anemia can cause hypoxia in the fetus, causing delays and premature birth in the fetus.At the same time, when anemia is severe, it will also threaten the health of the pregnant mother, causing edema and even heart failure.Therefore, all pregnant mothers must pay attention to anemia. During the first prenatal examination (preferably within 12 weeks of pregnancy), the outer peripheral blood and blood routine must be checked, and the blood routine is repeated every 8 to 12 weeks.

However, before the occurrence of anemia, the pregnant mother has begun to consume the iron stored by itself, and there are different degrees of iron deficiency. It is not until the supply is not in short supply.

However, mild iron deficiency may not have any symptoms and discomfort, and there is no abnormality in regular hemoglobin in blood. Therefore, if you find iron deficiency in the early stage, you need to detect the serum iron protein: when the serum iron protein concentration is <20 μg/L, diagnosed as a pregnancy ironlack.

Based on the level of storage iron, it is divided into 3 periods:

Iron reduction period: iron in the body decreases, serum iron protein <20 μg/L, rotor saturation and normal HB;

Iron deficiency red blood cell generation period: Red blood cell intake decrease, serum iron protein <20 μg/L, rotor saturation <15%, HB level is normal;

Iron deficiency anemia period: The degree of iron deficiency has affected the production of red blood cells. The serum iron protein is <20 μg/L, the saturation of rotor protein is <15%, and HB <110g/L.

How to eat anemia

During pregnancy is anemia, especially the high incidence of iron deficiency anemia. When the pregnant mother has not been deficient in iron, it should be prevented and improved through food in advance.

First of all, in addition to three meals a day, the most important thing is to eat meat.Don’t think that black fungus, red dates, and sesame are good iron supplements. Although they contain more iron, they are actually non -heme iron. The human body’s absorption rate is very low, less than 5%.What can really replenish iron is heminin iron, which refers to the iron contained in red meat, with high absorption rate, generally up to 20%to 30%.The protein rich in meat is also an important raw material for hemoglobin, and the vitamin B6 in the meat also plays a catalytic role during the generation of hemoglobin.

Secondly, intake of vitamin C.Vitamin C has the function of promoting iron absorption and utilization.Vegetables contain more vitamin C: kale, sweet peppers, pea seedlings, cauliflower.Fruit contains more vitamin C: fresh dates, kiwi, strawberries.

At the same time, vitamin A, vitamin E, and vitamin B2 are also beneficial to absorb and maintain the normal life of red blood cells.

Third, grain bran, nuts, tea, coffee, cocoa, and calcium will inhibit the absorption of iron. Pay attention to the amount of restrictions or iron -rich foods or iron intervals for more than 1 hour.

Fourth, serum iron protein is <30 μg/L.If the pregnant mother does not have the conditions to detect serum iron protein and the possibility of iron deficiency anemia, you can use the early pregnancy to produce under the guidance of a doctor, and the daily dose of small doses of element iron 30 ~ 40mg can effectively prevent the anemia during pregnancy.occur.

However, it should be noted that some pregnant mothers with anemia need to be transfused and "remove the iron" treatment, so before you figure out the cause, you must not supplement the iron by yourself.

Fifth, add small dose folic acid before pregnancy.Although folic acid is not the main force of hematopoietic as the same as iron, it also participates in the generation of red blood cells, which is considered to be auxiliary hematopoietic. Therefore, pregnant mothers should take 0.4-0.8mg folic acid daily from 3 months before pregnancy, at least until 3 pregnancy.moon.If you are diagnosed with giant cellular anemia, you should follow the doctor’s advice until the symptoms disappear and the anemia is corrected.

Sixth, if iron deficiency anemia has occurred, you can use oral iron or food supplementation to supplement iron. If the effect is poor or moderate, the iron must be used to strengthen the iron to strengthen the absorption.Severe blood transfusion.

Therefore, pregnant mothers should be treated as soon as possible. Do not drag to severe blood transfusion. It not only affects the growth and development of the baby, but also may be infected with various infectious diseases due to blood transfusion.

Well, this is here today. I hope that after reading the article, you can overcome the small difficulty of anemia as soon as possible!
