An important role in the successful work of the endocrine system during pregnancy is the so-called thyrotropic hormone (TSH). It is produced by the pituitary gland and is responsible for the normal functioning of the thyroid gland of the future mother and her baby. TTG stimulates the formation of important hormones of triiodothyronine (T3) and thyroxine (T4). They are responsible for the exchange of fats, proteins and carbohydrates in the body, work sexual, cardiovascular system, gastrointestinal tract, as well as for mental functions.
During pregnancy, the TSH score may increase. In most cases, elevated TSH levels are the norm, but only a professional endocrinologist can provide a reliable assessment of your condition.
Causes of increasing TSH in pregnancy
In the body of a future mother, the level of thyroid-stimulating hormone is controlled by the hypothalamus. It forms the so-called thyrotropin-releasing hormone (TRH), which enters the pituitary gland and stimulates the secretion of TSH. The number of "thyrotropic" during pregnancy constantly fluctuates: it increases, then decreases. Everything depends on the health of the mother and her baby.
The statistics show, that in 20% of women in the first half of pregnancy the norm of TSH is reduced to 0, 1-0, 4 mU / l and can even be completely suppressed. A low level of "teretropes" is observed at the end of the first trimester. If pregnancy passes without pathologies, then TSH gradually begins to increase. In some cases, TTG may remain somewhat reduced almost before delivery.
In others, 80% of TTG sometimes even "off scale". Doctors advise not to panic: TGH actively enhances the formation of thyroid-stimulating hormone - and it is quite acceptable for a pregnant woman. But at too strong deviation or rejection TTG from norm or rate there is a risk for the kid. The course of pregnancy in this case is complicated, but this is not at all an indication for its interruption. The level of TTG can and will continue to change over the course of all nine months.
Symptoms of increased TSH in pregnant
The daily norm of TTG in a healthy person is 0, 4-4, 0 mU / L. In future mothers, these rates can be slightly increased or underestimated. By the way, a very low level of TTG may indicate that you will have twins or even triplets. To accurately determine the level of TSH in pregnancy, a survey is conducted with the introduction of a high-sensitivity test system.
If the TSH rate during pregnancy has increased, you will notice the following symptoms:
- a slight thickening of the neck;
- general weakness, decreased activity, fast fatigue;
- sleep disturbance;
- pallor of the skin, puffiness;
- nausea, poor appetite, constipation;
- lowering of body temperature;
- a solid "increase" in weight;
- mental retardation, inattention, apathy, slow thinking;
- possible irritability.
If the thyroid-stimulating hormone is high and ranges from 7, 1 to 75 mU / L, this indicates hyperthyroidism - a condition caused by a persistent increase in the level of thyroid hormones.
Increased TSH. What to do?
If you notice the above symptoms, then do not self-medicate. Do not prescribe hormones for yourself or on the advice of your friends and do not practice "folk medicine".
The norm of the TSH level in pregnancy is determined only by doctors. If necessary, additional tests and examinations are prescribed, for example, fine needle aspiration biopsy of the thyroid gland or echographic examination.
If TSH is elevated in pregnancy, especially in the early stages, then in many cases, therapy with synthetic L-thyroxine (L-T4) is prescribed. Treatment begins with small doses of the hormone. Gradually, portions of L-T4 are increased until the TSH and T4 norm is established in the blood.
If before in the treatment of hyperthyroidism a natural dried and milled thyroid gland of animals was used, but now this technique has lost its relevance. Today it is rarely used, because patients are transferred to a synthetic drug. It is cleaner and has a stable level of activity.
A future mother needs to monitor her hormonal background and the state of the endocrine system throughout her pregnancy. Remember: for pregnancy to flow easily, and the fetus to develop correctly, it is necessary to lead a healthy lifestyle and eat fully. Forget that you can gain extra pounds! The health of your baby is much more important than weight, which, after giving birth, you can reset. Do not smoke cigarettes and do not drink alcohol. These harmful habits are forbidden, otherwise your crumb expects a delay in development and all sorts of pathologies, especially the thyroid gland.
Watch your health, do additional tests of TTG during pregnancy. Do not worry or get nervous: surveys are needed in order to exclude anxiety. And if in time to reveal deviations or rejections TTG from norm or rate, The negative impact on the health of the future mother and baby can be minimized or completely eliminated. Do not be ill and good to you TTG!
