Each organ of a girl during pregnancy directs her activity to bear a child. This also applies to the endocrine system.
While waiting for the child, it's hard to watch the hormonal background undergoing changes. The definition of the hormone TSH is mandatory. A thyroid-stimulating hormone gives more information about the state of the female body during pregnancy.
TTG is a hormone that is produced by the pituitary gland. The main work of TTG is to regulate the working process of the thyroid gland. Endocrinologists and gynecologists know that this hormone plays an important role in the process of pregnancy. It produces triiodothyronine and thyroxine, which are hormones of growth and are responsible for the metabolism.
It also affects the working process of such systems as sexual, digestive and cardiovascular. This hormone makes it possible to understand how correctly the child development is carried out.
The production of the hormone
TTG affects the production process of other hormones that affect the main body systems of women.
Also it acts on the general psychological state and mood. As soon as conception has occurred, the embryo begins to secrete the hormone hCG, thereby affecting the thyroid gland of the expectant mother. As a result, activation of TSH occurs.
The fetus does not have the ability to create the gland hormones, so it takes them from the maternal blood. In the female body, during pregnancy, a huge volume of thyroxine is released and the level of thyroid-stimulating hormone is reduced. In the process of development, when the embryo becomes a fruit, he has a personal thyroid gland, the mother begins to increase TSH to a standard level. Because of what his level is not constant during the entire pregnancy.
But there are certain limitations in the norms and, if there are deviations from the border, this indicates a malfunction in the body of the pregnant woman and that there is a risk of a normal development of the child.
The role of TSH in the body
Hormones of the thyroid gland strongly affect the entire body, since they are the metabolic regulator.
- If there is an overabundance of TSH in the body, thyrotoxicosis develops, which affects sleep disturbance, leads to nervous excitement, weight loss, increased body temperature and appetite.
- If there is a deficiency of TSH, there is a decrease in metabolism, there is an excess fluid in the body, apathy, drowsiness and reduced immunity. Sometimes the girls because of this, there may be a problem associated with the conception of the child.
- Hypothyroidism is a great danger, that is, the lack of a given hormone, which can be, both in the mother and in the child. If the mother has such a diagnosis, then later her child will have congenital thyroid disease.
- Infants with a diagnosis such as hypothyroidism may subsequently have a severe lag of absolutely all types of development. To correct it it is possible only, if in time to make replaceable therapy L-thyroxine. If you do not, then a child of five years of age will look like a one-year-old child.
Effect on pregnancy
TTG strongly affects the body during pregnancy, as it carries a risk to the fetus. His level shows the state of the thyroid in the mother.
During the planning of pregnancy with the usual delivery of the hormone, you can see only a certain deviation from the norm. If you take such an analysis during pregnancy, you will receive information about whether there is a tight work process of the gland or its invisible deficit.
A high level of TSH may appear if the pregnant woman has an appropriate level of thyroxine, but this will still have a negative impact on the fetus due to the influence on the development of the endocrine system, and on the initial weeks and on the formation.
A woman should think about the state of her own endocrine system also during birth planning. But it is worth considering that TSH does not affect the onset of pregnancy, but it is taken into account in conjunction with other analyzes. It is special for preventing the development of a child.
TTG decreases during the first trimester, and then increases. The level of the hormone is necessary when:
- the girl has a certain violation of the hormonal background
- in the girl the pathology of the thyroid
- during the general examination due to infertility.
No analysis is performed for healthy women.
Normal level
Sufficient production of thyroxine and triiodothyronine has an overwhelming effect on TSH, which leads to the fact that the level of this hormone decreases in the blood of a girl during pregnancy.
The standard level of the hormone is within its concentration of from 0.4 to 4.0 mU / l , but during pregnancy the hormone rate is observed according to a special table.
There is also an average hormone in the range from 0.2 to 3.5 mU / l .
It is worth noting that the trimesters have the following limits:
- 1 trimester - 0,1-0,4;
- 2 trimester - 0,3-2,8;
- 3 trimester - 0,4-3,5.
In some pregnant women, the level of the hormone remains unchanged.
Causes of oscillation
A child has a thyroid gland only by week 10, but completely begins to function only by week 15.After this week the body of the child will be able to independently produce TTG.
Until 10 weeks the child does not need this hormone, and he only gets T4 from his mother. As a result, the level of TSH in the body of a pregnant girl rises, there is a violation of its concentration. As a result, at the beginning of pregnancy, the mother begins to decline.
After 10 weeks, the work of the children's endocrine system is being adjusted. In the second trimester the functionality of the system of the female organism is fully established, the child begins to provide himself with the necessary hormone, the mother's TTG is normalized.
Elevated level of
The increased level of TSH in the first trimester is especially dangerous. That says that the thyroid gland is broken. In this case, the doctor appoints a synthetic hormone of thyroxine.
A high level of TSH may indicate:
- on adrenal gland failure;
- on gestosis;
- tumors of the pituitary gland.
It is necessary to understand that you need to adjust this level. Otherwise, and because the fruit does not receive the necessary hormones and there can be a miscarriage at an early age, or after birth, the child may have pathologies of the brain.
Understand that the level of TSH is elevated, you can for some moments:
- sleep disturbance;
- thickening or swelling of the neck;
- unhealthy paleness;
- fast fatigue;
- inattention;
- temperature reduction;
- greatly increased weight or decreased appetite.
If there are such symptoms, then it is necessary to pass the tests.
Treatment with elevated TSH
If the TSH rate during pregnancy is increased, this can lead to danger, and not to pathology. It should be understood that there is a threat and with a slight increase in the norm.
Intervention is not necessary if the hormone does not exceed 4 mU / L, but the free T4 has a normal value.
Correction should be made in the following cases:
- if T4 is produced in insufficient quantities;
- if the amount of titer of antibodies to TPO is increased.
To regulate the hormonal background of a pregnant woman, a hormone of synthetic origin is prescribed, iodine preparations. Synthetic hormone will need to be consumed during all trimesters of pregnancy, but the dosage is selected by the doctor. Also the doctor can and cancel earlier a preparation, but level TTG will be checked on each term.
Low TTG
An important threat is TSH, the index of which is close to zero.
- a low rate can be during a multiple pregnancy;
- , the zero indicator reports that it is possible for nervous overstrain, hyperthyroidism, pituitary dysfunction and benign tumor on the gland.
In addition, that a low score can worsen the condition during pregnancy, it can have a negative effect on the baby's nervous system. The pregnant doctor prescribes the mandatory intake of drugs that are responsible for suppressing the thyroid hormones T3 and T4.
There are signs that also can be understood that TTG is below the level:
- permanent headaches;
- high blood pressure;
- hand tremor;
- heartbeat will be more rapid;
- body temperature will constantly be at the level of 37 and above;
- weight loss, lack of appropriate weight gain;
- imbalance and nervousness.
Do not engage in self-treatment. Also, every girl should know that when planning pregnancy, you should check for hormones and follow all the doctor's recommendations.
