The norm of hemoglobin in pregnancy (3 trimester), high and low hemoglobin

And during the planning of pregnancy, and during the period of direct bearing of the child, the health of the woman should be the main priority of herself, as well as her family. The problems that can arise at this time and harm both the mother and the fetus are many. Some of them are associated with a lack of certain substances in the body or, on the contrary, with their excess. So, for example, an increase or decrease in the level of hemoglobin in the blood can adversely affect the health status and lead to the development of more serious diseases. What is dangerous change in its content in the blood? What is the norm of hemoglobin during pregnancy (3rd trimester)? This will be the topic of this article.

Why it is important to monitor the level of hemoglobin

The hemoglobin molecule has a protein and a certain iron compound in its composition . Its role is to transport oxygen through the bloodstream to each of the cells in the human body. And also hemoglobin provides the release of cells from the product of their life - carbon dioxide. Any violations entail significant metabolic disorders, and consequently, the work of internal organs and whole body systems.

The consequences of a sharp decline in hemoglobin for a pregnant woman's body may come as follows: weakness and metabolic disorders, pathology of the nervous system or fetal hypoxia, and even delayed child development.

Why hemoglobin decreases

There are a number of reasons that affect the reduction of hemoglobin in the blood. The most common of these is the lack of iron in the body. This condition can be effectively corrected with the help of medications (this issue will be discussed in more detail later in this article). Also effective is the introduction of a constant diet of foods such as meat in large quantities, cranberries, pomegranates, buckwheat, sour apples, as well as buckwheat honey.

Another reason for the decrease in hemoglobin is the lack of vitamin B12. This is due to the fact that it is cobalamin involved in the synthesis of hemoglobin in the human body. You can replenish the amount by consuming a large amount of greenery in your food.

Another logical reason for lowering hemoglobin is the lack of protein, because it is the protein that is an important part of the hemoglobin molecule. It is important that the daily diet of a pregnant woman includes a large number of quality proteins, otherwise, even if there is an abundance of iron in the body, the hemoglobin molecule will not be synthesized. The protein norm, which must be consumed daily, can be calculated using a simple formula: for every kilogram of a woman's mass, 2-3 g of protein should be present.

Methods for increasing hemoglobin

Of course, in order to reflect the norm of hemoglobin in pregnancy in the results of the general blood test (the trimester is the period when it is very important to know such an indicator), it is necessary to carry out the treatment that corresponds directly to the individual cause of hemoglobin decrease. However, there are general preventive measures that can be used to improve the current situation. For example, it's important to walk out on the street, especially before going to bed. If the general condition and recommendations of physicians do not prohibit physical activity, it would be prudent to perform exercise packages for pregnant women, which promotes active transportation of oxygen.


Medicines that include iron in their composition should be taken for a sufficiently long time. In the case of taking such drugs, the normalization of all parameters in the results of blood tests of the pregnant woman occurs only six to eight weeks after the start of medication.

As a rule, drugs that contain iron should be taken orally. The introduction of such drugs as a solution for injection is possible only in some cases, such as ulcer, severe anemia, individual intolerance of such drugs in the form of tablets or the inability of the body to metabolize iron when taking tablets.

The most effective use of drugs that contain iron, along with those components that contribute to better digestibility of the substance in the body, such as folic acid or ascorbic acid. For the convenience of patients, many medicines have been created that contain all the necessary substances in the complex.

Any initiative in this matter is pernicious. The administration of drugs and dosages should be performed exclusively by a specialist who regularly monitors the results of a general blood test.

The norm of hemoglobin during pregnancy in the third trimester

The third trimester of pregnancy is the period from the twenty-ninth to the fortieth week of pregnancy. This time is significantly different from the two previous trimesters. Now the body of a pregnant woman is fully adapted to the development of the fetus and the needs of the child, which is actively growing and developing.

The norm of hemoglobin during pregnancy (3 trimester) is from one hundred and ten to 140 grams per liter. This period is extremely important, because right now the main set of mass is carried out by the baby. It is critically important that hemoglobin at this time fluctuate only within the established norm.

The level of hemoglobin can be effectively controlled by proper nutrition. Other methods of preventing anemia will be discussed later in this article.

Anemia in pregnant women

In no case should you ignore the blood tests set by your doctor (including the analysis for glycated hemoglobin, the pregnancy rate of which should not be exceeded), because it is this type of research that can identify the problem on time. For example, this is the only way to accurately establish the diagnosis of "Anemia", but this disease has a detrimental effect on the course of pregnancy and fetal development.

Symptoms of anemia

In order to avoid unpleasant consequences, it is important to notice the symptoms in time and react to them correctly. So, if hemoglobin, when the pregnancy rate of the 3 trimester of which is clearly marked in medicine, is greatly reduced, the following symptoms may occur: persistent weakness, uncommon fatigue, pale skin, as well as noticeable dryness, obtrusive dizziness, sleep disturbance, poor hair condition and Nails, pain in the head, irregular stools, tinnitus and loss of consciousness, shortness of breath with minor loads, improper taste perception, blue lip color.

Prevention of anemia

However, there is always the possibility to regulate hemoglobin to some extent, the norm in women during pregnancy varies depending on the period. So, the main measures for the prevention of anemia are: constant monitoring of the current indicators by conducting a general blood test, which should be carried out both at the time of registration and at the dates of eighteen, twenty-eight and thirty-five weeks; The right diet, which excludes vegetarianism. It is also important to treat all emerging infectious diseases on time and in quality, even at the stage of pregnancy planning, so that there are no additional problems during the bearing of the child, while the treatment of any chronic diseases should be carried out by competent narrow specialists. It will also be useful to take high-quality iron preparations in preventive doses.

Increased hemoglobin

Usually when it comes to problems with hemoglobin, keep in mind that the hemoglobin in the blood is lowered. When pregnancy, however, the opposite happens. Elevated levels of hemoglobin also do not bode well for a woman in the position. Despite the fact that adverse reactions and various complications associated with an increase in hemoglobin occur much less frequently, nevertheless, one should not ignore this question in any case.

Who is at risk? First of all, residents of high-mountainous areas or areas with low-density air. Also, those women who are professional athletes, whose body is adapted to regular, great physical exertion, are at risk. Some diseases, such as various tumors, heart disease, thickening of the blood and various cardiopulmonary pathologies, can also cause the norm of hemoglobin during pregnancy (3 trimester) to be significantly exceeded.

The first two of the described types of elevated hemoglobin do not pose a threat to either the future mother or the fetus. However, women who have the problems described in the third paragraph should pay the attention of their attending physician to this and be under his constant supervision.


It is critically important to monitor such an indicator of a general blood test, like hemoglobin in pregnancy. Norm 3 trimester (the table of normative parameters of hemoglobin is presented above) - 110-140 g / l. Any deviation from these indicators can harm the mother's body and affect the growth and development of her child. Both increased and decreased hemoglobin is corrected with the help of special medicines and proper nutrition. Moreover, the condition for which low hemoglobin is characteristic is more dangerous and threatens with serious consequences. Therefore, you can not ignore the symptoms described in this article. Be attentive to your health, because the health of the unborn child depends on him in full measure.
