The thyroid gland secretes important for the body's hormones - thyroxin and triiodothyronine, which are necessary for proper development of the fetus of all organs and systems. Thyroid hormones and later, after the birth will support all the organs and systems baby's growing body. The lack of thyroid function causes various complications of pregnancy.
How does the thyroid gland during pregnancy
Normally during pregnancy increases the function of the thyroid gland, which helps it to some widening. This peculiarity was known to the ancient, as a sign of pregnancy, women in ancient Egypt was considered a gap thin silk thread on the neck, which is supposed to wear a married woman.
In fetal thyroid gland begins to develop at the end of the first month of pregnancy, and by the end of the third month, she can already accumulate iodine itself synthesize hormones. By the end of the fourth month of pregnancy, the thyroid gland of the fetus is fully operational.
In this regard, it is clear that while its thyroid gland in the fetus are not formed, all the organs and systems developed under the influence of hormones of a pregnant woman. And then you start running your own child's thyroid gland, it will need iodine (from it synthesized thyroid hormones), which enters the body of the child from the mother. From the mother's body needs increased amounts of iodine. If iodine comes not enough, it is very dangerous for a child - he may form congenital hypothyroidism

Which will lead to a violation of the physical and mental development.
Influence of hypothyroidism on the condition of a pregnant woman and the fetus
If in the area, where a pregnant woman, there is a deficiency of iodine, the hypothyroidism she can form before pregnancy and proceed hidden. Therefore, in the planning period of pregnancy is desirable to examine the blood for thyroid hormones. If it showed a reduction in thyroid function that is prescribed hormone replacement therapy - drugs have to take during pregnancy.
This should be done necessarily, because hypothyroidism is often threatened miscarriage, fetal death or birth of a child with a variety of developmental abnormalities. Often in such cases developed deaf-mutism, impairment, brain damage to the further development of cretinism. Negatively affected by the lack of thyroid hormones

and the mother's body.
Causes of hypothyroidism in pregnant women can be very different, but most often it occurs against the backdrop of thyroiditis - inflammation of the thyroid gland. Furthermore, hypothyroidism can begin after resection of the thyroid gland, with a deficiency of iodine. Secondary hypothyroidism occurs due to various diseases of the pituitary gland and the hypothalamus.
Symptoms of hypothyroidism in pregnant women
If a pregnant woman is reduced thyroid function, then doubled her complaints of fatigue, lethargy, typical of pregnancy. In addition, the woman has symptoms such as sensitivity to cold (it is constantly freezing), dry and flaky skin, brittle nails and hair, hair loss.

Often there is nasal congestion, the tongue swells and does not fit in the oral cavity, on each side there are imprints on the side of the teeth.
Many of the signs of hypothyroidism referred to signs of pregnancy, but if you look closely, they can always be distinguished.
