Proper functioning of the body requires constant production of thyroid hormones – thyroxine and triiodothyronine.They control the oxygen consumption and energy processes of the body, regulate the body temperature, are needed for proper maturation and differentiation of cells, have an effect on the transformation of proteins, carbohydrates, fats, nucleic acids and vitamins.The element necessary for the production of hormones in the thyroid gland is iodine, delivered to the body with food and air.Iodine compounds present in the air are absorbed by the lungs and skin.About 800 million people, or 1/7 of the entire human population, are affected by the effects of iodine deficiency.
The need for iodine increases during puberty and menopause and during pregnancy and feeding.
Iodine deficiency in the body causes thyroid enlargement.
Sizes of the so-calledthe will of indifferent is different.Sometimes thyroid hyperplasia is difficult to see, in other cases it is so large that by compressing the larynx and trachea it causes coughing and shortness of breath.Enlarged thyroid initially does not cause health complications but after some time, there are necrosis, cysts, calcifications, nodules.The gland activity may be increased or impaired.About 2.5-6% of people over the age of 40 suffer from oligosymptomatic hypothyroidism difficult to detect without assessing the concentration of thyroid hormones in the blood.Sometimes thyroid cancer develops in the seemingly inert will.Goals occur sporadically or endemically.We speak of the endemic occurrence of will when, within a defined geographical area, over 10% of adults or over 20% of children have a go.
The lack of iodine is particularly dangerous in the fetal, neonatal and infant periods because it disturbs the maturation of the brain, which in turn leads to mental retardation and other neurological complications.
Fetal disorders due to iodine deficiency
The decrease in iodine stocks has a negative impact on the psyche of an adult person and can also be the cause of a number of emotional disorders.In the endemic areas, the will of the intelligence of the living population there is lower compared to the inhabitants of areas not threatened with deficiency of this microelement.
Prophylaxis of the inert goose present endemic consists in increasing the amount of iodine in food products.The best method is iodization of table salt.According to doctors, the amount of iodine in a kilogram of salt is insufficient (it is 4-8 mg and should be 25-30 mg KJ).Sufficient amount of iodine has table salt with microelements with an additional iodine sign.
