Kapitel
Jod, ein für die Schilddrüsenhormonsynthese essentielles Spurenelement, kommt natürlicherweise in Meeresfrüchten, Kreuzblütlergemüse sowie in maritimem Aerosol vor, von wo aus es über die Atemwege und die Haut aufgenommen wird. Aufgrund der weit verbreiteten Mangelerscheinungen wird es zudem routinemäßig dem Speisesalz zugesetzt. Welche klinischen und metabolischen Folgen sind mit einem chronischen Defizit oder einer Überdosierung verbunden? Auf welche Weise beeinflussen diese Störungen den Schwangerschaftsverlauf, die fetale Entwicklung sowie die Gesundheit von Kindern verschiedener Altersgruppen unter Berücksichtigung ihres physiologischen Bedarfs?
Iodine deficiency
Iodine deficiency causes disorders, which can vary in severity depending on the severity of the disorder. It is associated with the occurrence of thyroid disorder in adults, as well as the presence of simple willpower. This condition causes impairment affecting metabolic and reproductive functions. In children there is creatinism, so the disease of children whose mothers, especially in the first weeks of pregnancy, suffer from thyroid insufficiency and at the same time a deficiency of this element.
Excess iodine
This is a very rare situation, in fact uncommon. Usually there is only inhibition of the synthesis of thyroid hormones or allergic reactions, but they are usually associated with diseases or the use of medicines. Excess iodine in the body causes hyperactivity of the thyroid and the appearance of will. Unfortunately, due to the increased activity of the mucous glands, nausea can be felt. Sometimes there are vomiting, diarrhea, and also cataract symptoms in the nose and bronchi.
Iodine is pregnant
An adequate concentration of iodine in pregnancy is extremely important, especially in the first weeks of pregnancy. Deficiency of this element and associated thyroid failure leads to reduced production of hormones by this gland. As a result, a fetus that has not yet developed a thyroid suffers from a lack of the hormones T3 and T4 from the mother, necessary for the formation of the central nervous system. Therefore, the child is at risk of developing irreversible mental defects.
Iodine for children
Iodine is an extremely necessary element for the proper development of children. This element is responsible, among other things, for regulating energy changes. It is also essential for proper growth and sexual maturity. It has been noted that a deficiency of this microelement can cause mental and physical damage.
