When there is not enough iodine in an organism of

Iodine is necessary for synthesis of hormones of a thyroid gland. Business this responsible as the thyroid gland regulates work of all organism.

Hormones which it develops (tireoidny) influence reproduction, growth, a differentiation of fabrics and a metabolism. In other words, the thyroid gland defines with what frequency heart how many the eaten food will be postponed in the form of a glycogen (a power stock) and how many - in the form of fat whether the person will freeze in cold weather will fight or not.

of

Is normal in a blood-groove there have to be about 600 mkg of iodine from which a thyroid gland 75 mkg get daily. But deficiency of iodine can easily arise, and work of a thyroid gland should not be interrupted therefore in it there is always an iodine reserve (8000 mkg) which is spent only at very expressed deficiency.

in One more way “spread straws“ on a case of deficiency of iodine is development by a thyroid gland of two hormones: a tetrayodtironina (it tiroksin, it is T4; contains 4 atoms of iodine) and a triyodtironina (it T3, it contains 3 atoms of iodine). They are very similar on action, but T4 possesses long action, T3 - shorter and strong. A ratio of T3 and T4 in an organism without deficiency of iodine - about 1:4.

knew to
Of iodscarce diseases in ancient India and China. Treatises in which it was recommended to add the crushed and dried up seaweed to food remained.
the ratio of T4 and T3 is broken by

At insufficient intake of iodine in an organism. It occurs because iodine for synthesis of T3 it is required less therefore it is more actively synthesized. The problem is that the brain needs T4, it at which lack of iodine will arrive less.

does not have

the sea - whether there is no iodine

Can distinguish a lack of iodine? In an organism of separately taken person - alas, no. The matter is that in blood the level of iodine is not defined, and in urine indicators often change. Therefore measurements on the content of iodine in urine are made in large quantities - the group has not less than 30 people, 2 times a day are desirable. Average value is called a yoduriya median. It is possible to judge by it whether the concrete area is iodscarce or not. If the median of a yoduriya is lower than 100 mkg/l, then ioddeficiency is available.

According to WHO data, the picture of planetary shortage of iodine looks impressive: 1570 million people have risk of development of iodine deficiency diseases (and it slightly less, than 30% of the population of Earth). From which more than it is already available at 500 million people symptoms of iodscarce diseases.

A where the place of Russia in this statistics? To please there is nothing: the majority of regions of Russia are iodscarce. The most reliable guarantee of the fact that people receive enough iodine - only proximity to the sea.

craw Sizes (WHO, 2001):
  • Degree 0: there is no craw, the thyroid gland at a palpation corresponds to length of a phalanx of the thumb surveyed.
  • Degree 1: at a palpation it is increased, there can be knots.
  • Degree 2: increase in a thyroid gland is noticeable at usual position of a neck.

Feature of the iodscarce area that from the products received in it it is almost impossible to extract iodine. It contains there, in - the first, in very small amounts, and in - the second, quickly collapses. What is the lack of iodine fraught with?

the Master without iodine

According to mass representations, leads deficiency of iodine to emergence of a so-called craw. The problem is that between shortage of iodine and emergence of a craw there is a certain temporary distance.

Not really expressed ioddeficiency is expressed to

in decrease in intelligence, memory violation (especially at children) and increase in a thyroid gland.

by

In regions with the expressed ioddeficiency at women breaks reproductive function, the quantity of abortions and still births increases, perinatal and child mortality increases. The most adverse effect of shortage of iodine occurs on children, beginning from the pre-natal period and finishing with the puberty period.

And that craw?

the Craw doctors call

increase in a thyroid gland without violation of its function. Definition of “endemicheskiya“ is added if in this region at children of younger and middle school age increase in a thyroid gland more often than in 5% of cases is noted. In Russia it occurs practically in all regions (for example, according to the measurements which are annually made by doctors - tiroidologa, in Moscow and St. Petersburg - about 10%, in Nizhny Novgorod - more than 15%).

in half of cases the craw develops till twenty years, the remained half is generally made by women after pregnancy, childbirth and feeding by a breast. At men the endemichesky craw develops much less often, and it depends on degree of expressiveness of ioddeficiency. In areas where ioddeficiency is insignificant, 7 - 10 women are the share of one sick man.

At first increase in a thyroid gland happens due to increase in the size of its cages. Iodscarce colloidal craws are not oncology, and attempt of separate cages to pick up more iodine. The quantity of cages begins to increase in the started cases. If not to treat a thyroid gland, then annually it will increase approximately by 5%.

by

function of a thyroid gland At some point begins to be broken: it can lead to emergence of knots in it. At further progressing of a disease can develop functional knot autonomies - that is, it will cease to submit to regulation and will begin to emit hormones in the rhythm. In this case surgical treatment is most often appointed. But generally change of a thyroid gland proceeds asymptomatically, and only at the expressed increase patients see a doctor.

of Norm of consumption of iodine (under the WHO recommendation):
Children of chest age - 50 mkg
Children from 2 to 6 years - 90 mkg
Children from 7 to 12 years - 120 mkg
Teenagers are more senior than 12 years - 150 mkg
Pregnant women and the feeding women - 200 mkg

How to fill a lack of iodine

we Will make a reservation at once: it is about prevention, but not about treatment.

Iodinated salt - an ideal product. There are 2 compounds of iodine in salt: iodide and iodate. The last is considered more resistant: such salt can be stored 2 years, salt with iodide - only 6 months. But it is necessary to remember that when heating connection collapses and iodine evaporates therefore it is the best of all to salt food it is recommended at the very end of preparation.

Iodine in seafood . Here the approximate content of iodine in seafood: 5 - 400 mkg on 100 g and in sea cabbage: 5 - 300 mkg / 100 g. It is visible how the content of iodine therefore it is hardly possible to trace it in house conditions varies. Products with the stablest content of iodine: river fish (70 mkg / 100 g) and oysters (60 mkg / 100 g). In other products its quantity in general is scanty - about 10 mkg / 100 g

As it is impossible to compensate for the iodine deficiency. There is widespread council for completion of deficiency of iodine: to daily drink milk to which several drops of the iodine intended for disinfection are added. It cannot be done: each drop contains 6000 mkg of iodine, that is, in 30 times more of daily requirement, such dose completely will block a thyroid gland.
