Iron during pregnancy ensures normal functioning of the body of the mother and baby. It contributes to the production of blood, which provides a link between a woman and her child. Let's consider the most topical questions regarding the norm, level, deficiency and excess iron in the body of a pregnant woman.

During pregnancy, the female body works with a double load. That's why the main task of a woman is to help the body cope with it. Iron (Fe) - this is the element that is required by pregnant women in large volumes. It is responsible for the production of blood and the formation of erythrocytes, which are responsible for supplying the body with oxygen.

Iron in pregnancy

The lack of Fe in the body of a pregnant woman is a shortage of red blood cells. In this case, the woman develops anemia, which is accompanied by a very unpleasant symptomatology. Excess iron causes problems in the body. Therefore, it is very important to maintain its level in the norm and take care of the state of the body that works for two.

How to take iron during pregnancy?

How to take iron during pregnancy - this question can be answered by a gynecologist and a doctor who controls the condition of the woman's body. Most often, Fe is prescribed in syrup, tablets or drops. Much less often resort to the use of iron-containing injections. Since injections contribute to the appearance of abscesses and can worsen the process of blood clotting. Iron in tablets is the most convenient form for taking. Let's consider how to take iron during pregnancy.

  • Iron-containing drugs can not be taken with other tablets and medications.
  • Iron must be washed down with water (tea, juice, milk and so on - do not fit).
  • After taking Fe, it is not recommended for two hours to eat foods that contain calcium, that is, antacids. Since they worsen the work of the intestines.
  • If you forget to take the drug at the appointed time, then the next dose should go on schedule, you can not change the dosage of the drug yourself. The excess of Fe in the body is much worse than the defect.

Prick of iron during pregnancy

Iron pricks are prescribed in pregnancy if the woman has impairment of absorption of Fe, digestive and gastrointestinal tract diseases, duodenal ulcer, intolerance to iron preparations and side reactions (dizziness, vomiting, nausea). The only side effect after injections during pregnancy is a feeling of overflow of the stomach. Most often, injections of Fe with preparations "Ferlatum", "Ferrum Lek" and "Maltofer" are used. The peculiarity of these injections is that they do not cause side effects and do not have a negative impact on the mother and child.

Iron during pregnancy is one of the most important microelements. Fe is responsible for the normal course of pregnancy. Lack of iron is the cause of serious illnesses, both in the mother and in the baby. Excess iron in the body of a pregnant woman causes pathologies and can cause a miscarriage. That is why every pregnant woman should regularly take a blood test to determine the level of Fe in the body and, if necessary, adjust the results. Since the normal level of iron during pregnancy is the pledge of the birth of a healthy baby.


An overdose of iron during pregnancy adversely affects the female body and the development of the child, just like the deficiency of this microelement. Excess Fe can cause gestational diabetes, lead to the termination of pregnancy and the development of infertility. That's why taking any iron-containing drugs is necessary under the supervision of a doctor.

The main symptoms of iron overdose during pregnancy are diarrhea, vomiting, headaches, abdominal pain. The daily dose of Fe for pregnant women should be at the level of 27-30 mg per day, but this figure varies depending on the individual characteristics of the female body. Any iron-containing drugs can not be taken for a long time, as this can lead to excess iron in the body and will lead to serious consequences that are a risk for the normal course of pregnancy and child development.

The level of iron during pregnancy

The level of iron during pregnancy is about 30 mg of substance per day. The bulk of it comes with food. It does not matter if one day the body receives 10 mg of Fe and the next 40 mg. On average, in two days you will get the body's required norm and do not feel the symptoms of deficiency.

Significant costs of iron during pregnancy require constant replenishment of stocks. So, for example, a child during pregnancy needs at least 400 mg of Fe. Increasing size of the uterus takes about 50 mg of the substance, the construction of the placenta and its normal functioning - 100 mg and so on. In addition, the process of metabolism is accelerating in the female body, which requires an additional 500 mg of the microelement. During childbirth, a woman loses about 200 mg of iron. Many women during pregnancy are additionally prescribed drugs that make up for the lack of this macronutrient: injections (the drug "Ferrum Lek"), tablets "Sorbifer" and vitamin complexes.

Serum iron in pregnancy

Serum iron during pregnancy is an analysis that allows you to determine its concentration in a woman's blood. The concentration of this macroelement depends on resorption and accumulation in the intestine, spleen, stomach and bone marrow. The level of serum iron varies throughout the day, the highest levels are observed in the morning. During pregnancy, serum iron levels decrease, especially in the second trimester. This is due to the formation of the internal organs and glands in the child.

Analysis of serum iron in pregnancy can determine the deficiency or excess of this trace element in the blood. When Fe is deficient, anemia begins, which is accompanied by very unpleasant symptoms. Excess serum iron also causes diseases that adversely affect both the health of the mother and the development of the child. Detailed diagnosis of the level of iron can be done with the help of complex laboratory diagnostics, which will allow to determine the process of metabolism of this macroelement in the body and the level of distribution.

The norm of iron during pregnancy

The norm of iron during pregnancy is at least 30 mg of substance per day. If the body lacks Fe, then anemia begins. In order to determine its amount in the blood, it is recommended to pass a blood test to determine the level of serum iron. In a normal state, that is, in a healthy body, this figure is from 13-30 μmol per liter of blood. If the results of the analysis show a value below 13, then it is a deficit of Fe.

The need for this macronutrient in pregnant women is twice as high as in men and not in pregnant women. That is why in the diet of a pregnant woman should be foods rich in Fe. This will maintain its level in the norm, ensure the normal course of pregnancy and the birth of a healthy baby.

Iron deficiency in pregnancy

Deficiency of iron during pregnancy arises from the lack of this trace element in the body of the future mother. If a pregnant woman loses Fe, then this lowers the level of hemoglobin and causes anemia. There are certain factors that increase the risk of developing deficiency of Fe during pregnancy. First of all, these are problems with iron deficiency before pregnancy and chronic diseases. Multiple fetuses and early toxicosis also cause deficiency of Fe. If a woman before pregnancy had long and profuse menstruation, then this is another factor in the development of iron deficiency in pregnancy.

At many pregnant women shortage of iron starts to be shown in the second trimester of pregnancy. The shortage is exacerbated in the winter and spring periods, when food is not enriched with iron-containing substances. Diagnose the lack of Fe using a blood test and the hemoglobin content in it. The lack of iron during pregnancy adversely affects the health of the child. Babies who felt a deficiency of Fe in the womb are susceptible to infectious diseases and allergies.
