The rate of glycated hemoglobin during pregnancy and the determination of its level


The period of planning the child and his expectations require attention to the state of health of women. One of the important indicators on which doctors pay special attention is glycated hemoglobin during pregnancy. Its indicator determines the percentage of the special protein in the blood - hemoglobin, which is connected with glucose. Often in pregnant women, the indicator fluctuates, which raises many questions. What should be glycated hemoglobin in pregnant women? Why do the analysis? What does the result show? Many future mothers are waiting for answers.


  • When is the analysis assigned?
  • Norm of indicators for pregnant women
  • What to do to bring the indicators back to normal?

When is the analysis assigned?

In some cases it is difficult to determine the presence of diabetes in a patient - a blood test for sugar can show different results for a number of reasons. Such fluctuations in pregnant women - an occasion for additional diagnostic studies, the doctor assigns an analysis to determine the level of glycated hemoglobin.


If there are diseases accompanied by abnormalities and metabolic disorders, it is required to follow the changes in glycated hemoglobin unconditionally.


The doctor will write a direction for analysis if the patient has such illnesses or pathological changes:

  • the presence of diabetes diagnosed before the onset of pregnancy;
  • primary identification of gestational diabetes in the period of expectation of the child;
  • disorders of kidney function caused by diabetes mellitus;
  • hyperlipidemia;
  • persistent high blood pressure.

The analysis will be prescribed to women whose older children have metabolic problems, they have a metabolic disorder. Fear of doctors cause pregnant, close relatives of whom are ill with diabetes - additional diagnosis in such cases is shown.

For the analysis, blood from the finger or vein is used. For reliability of indicators it is required to take into account the rules:

  • the study is conducted in the morning, before it not to eat food (at least 5 hours before the procedure), fizzy drinks and tea;
  • Do not perform a diagnostic procedure after significant blood loss caused by surgery or blood transfusion.
Blood sampling for analysis

Norm of indicators for pregnant women

In a healthy woman who registered in a women's consultation, the rate of glycated hemoglobin does not exceed,%. The percentage result is calculated from the ratio of the mass of glycated hemoglobin to the total mass of hemoglobin. The indicator above indicated is a dangerous signal, which indicates the failure of metabolic processes, dangerous for the pregnant and for the future baby. It is recommended to undergo regular analysis once a month and a half. The dynamics of the results will allow us to notice dangerous changes in the body of the woman in time, to carry out corrective treatment.

If the future mother has an identified diabetes, doctors will pay particular attention to the glycated hemoglobin index, the pregnancy rate of which in such cases differs from the usual one. The rate in pregnant women with such a disease is exceeded to two times.

The level of glycated hemoglobin in the body of a woman expecting a baby can be lowered, the indicator is lower,%. Often the decrease occurs for reasons:

  • increase in the daily requirement for iron during pregnancy;
  • presence of blood pathology - hemolytic anemia, in which the destruction of red blood cells;
  • with low blood sugar or hypoglycemia;
  • insufficient elasticity of blood vessels, their fragility, leading to frequent bleeding.
Products that are indicated for use during pregnancy, which can normalize the level of glycated hemoglobin

What to do to bring the indicators back to normal?

It is important to adjust the increased or decreased glycated hemoglobin, the rate of which for pregnant women, depending on the term and the impact of certain factors, may vary. Table, in which the doctor enters the results of the analysis of a woman, allows you to track the dynamics of changes in indicators, assign corrective treatment or other measures.


Low level of glycated hemoglobin in pregnant women is corrected by drug treatment, the doctor prescribes the reception of vitamin-mineral complexes with iron. The patient is recommended a diet that includes foods with a high content of this element.


The results of the analysis with indicators from, to,% should be alerted. With such indicators, the doctor, who leads the pregnancy, prescribes a preventive low-carbohydrate diet, which helps to correct the metabolic processes.

Interest rates ranging from, to,% borderline for the development of diabetes, require strict adherence to diet, healthy lifestyle. If the analysis showed a result more than% of glycated hemoglobin, an additional diagnosis of diabetes should be urgently carried out and, if necessary, treatment should be started.
