The thyroid gland began to work long before you were born. It is laid at 4-5 weeks of intrauterine development, and at 6-8 weeks, the normal development of the fetus already depends on the hormonal activity of the thyroid gland. The hormones it produces both before and after the birth of a child affect its growth and the development of the central nervous system. And for the production of all these hormones, the gland needs iodine, which it “strains” from the bloodstream.
Today, almost all of our compatriots experience iodine deficiency., since our natural Central Russian soil and water are traditionally poor in this element, and not everyone is concerned about daily provision of iodine-containing seafood. Therefore, iodine deficiency to a greater or lesser extent is a reality for any of us. And along with it – a good dozen of all kinds of diseases that affect the thyroid gland and the whole body as a whole.
Once in conditions of iodine deficiency, the thyroid gland begins to fight. To capture more iodine from the bloodstream, it increases. The so-called endemic goiter appears, thanks to which the lack of natural iodine is successfully compensated and the normal secretion of hormones is maintained.
There is a special disease – congenital hypothyroidism. This is when the thyroid gland in a newborn is completely absent or underdeveloped (just the reason for this, as a rule, is the insufficient intake of the necessary drug by the future mother).
Iodine is a vital trace element. It is essential for the synthesis of thyroid hormones: T3 (triiodothyronine) and T4 (thyroxine). For the normal synthesis of these hormones, a daily intake of 200-300 micrograms of iodine with food is necessary.
With iodine deficiency in the human body, the thyroid gland cannot synthesize hormones in sufficient quantities, all metabolic processes are disrupted. Especially dangerous is the lack of iodine for children, adolescents, pregnant and lactating women.
However, it should be borne in mind that iodine in large doses suppresses thyroid function and causes temporary hypothyroidism. Therefore, the “golden” mean is important.
Prevention measures are simple and accessible to many – the use of iodized salt in cooking, the consumption of special iodized bread, the introduction of seafood into your diet (at least the same seaweed, which today is affordable for most residents of our country).
