Correctness of this process in the fetus is provided by increasing the concentration of thyroid hormones in the pregnant woman. Normally, an increase in the synthesis of thyroid hormones during pregnancy reaches 50%. Thus, the thyroid gland has a positive effect on pregnancy.
What changes can be observed in the thyroid gland when carrying a child?
The thyroid gland itself during pregnancy also undergoes changes. So her work is stimulated not only by the thyroid-stimulating hormone of the pituitary gland, but also by the chorionic gonadotropin, which produces the placenta. With an increase in its content in the blood, the synthesis of the thyroid-stimulating hormone decreases. That is why, in some women, there is a so-called transient hyperthyroidism, which refers to thyroid diseases and is not uncommon in pregnancy.
Influence of the thyroid gland on the course of pregnancy
It must be said that the thyroid gland has an effect, both on the pregnancy itself and on the postpartum period. So, with pathological processes in it, a woman can observe:
- arterial hypertension;
- detachment of a child's place;
- spontaneous miscarriage;
- postpartum uterine bleeding.
Also, quite often in violation of the functioning of the thyroid gland, babies with malformations, small weight, deaf-mute, dwarfism and even mental retardation are born.
With a disease like Graves' disease, the only effective method of treatment is to remove the thyroid gland , after which the onset of pregnancy is difficult. In such cases, a woman planning pregnancy, a course of replacement therapy with L-thyroxine is prescribed.
