T3( triiodothyronine) - one of the leading hormones, produced by the thyroid gland in both female and male organisms. There are two forms. The first form is a free hormone, and the second is a bound form that has a blood plasma association. The sum of these forms is a common T3.The share of free T3 in it is only a fraction of a percent, but it provides all the physiological properties inherent in the thyroid gland.

to contents ^Norm
In modern laboratories use a variety of equipment and, accordingly, different sets of reagents. Therefore, there are no single norms of hormones today, in fact, there are only indicative figures.
For men
In general, the norms are universal for women and for men. As a rule, they range from 2.6 to 5.7 pentamol / liter, depending on the reagent.
to table of contents ^In women
The norms of free T3 in women may differ not only according to the type of laboratory equipment or seasonality, but also for other reasons related to the features of the functioning of the female reproductive system. Gynecologists are often called free T3 "female" hormones, as it is responsible for the woman's ability to produce a healthy baby.
to the table of contents ^Child
The norm in children varies depending on their age. So, for children under the age of 3 days the rate is from 3 to 12.1 petalol / liter, for children aged 2 to 30 days - from 3 to 8 petalol / liter. In a child from 1 to 12 months of age, the norm ranges from 2.3 to 9.8 petalol / liter, from 1 to 17 years, from 3 to 6 petalol / liter.
Than the deviation from the norm is dangerous
With a rise in the personcan be subjected to frequent and severe headaches, there is a prolonged increase in body temperature, increased heart rate, "interruptions" in the work of the heart, weight loss. There may be trembling of hands, psychological imbalance.
The lowered level leads to quick fatigue, muscle weakness, causeless cramps, sleep disorders, slow thinking.
to the table of contents ^Possible reasons for the rise and fall of
The rise often happens in the fall and winter, and its minimum level usually reaches in summer. The increase is also due to varieties of thyrotoxicosis.
The decline occurs with different deviations in the production of hormones by the thyroid gland. It can be caused by the following factors:
- autoimmune thyroiditis( Hashimoto's thyroiditis): the cells of the gland cease to produce completely or produce hormones with high deficiency, since immunity destroys some of them;
- treatment of diffuse( or nodular) toxic goiter with thyreostatics( mercazolil, tyrosol, propitsil) in excess doses;
- removal of the thyroid gland or part of it;
- therapy for diffuse toxic goiter with radioactive iodine;
- use of Cordarone, Amiodarone and other preparations with a significant iodine content.
What to do
To maintain health, the hormone should be within normal limits.
to contents ^With increased
With an elevated free T3 content in the body, an additional examination should be performed. Sometimes it may turn out that initially it was just a mistake - inaccuracies in the analysis of hormones are not so rare. If the deviation from the norm is confirmed, it is necessary to consult a doctor-endocrinologist. He will explain what causes the deviations, select an individual treatment regimen for restoring the hormonal balance, send it to additional tests.
to table of contents ^With reduced
With a lowered T3 content, it is also necessary to undergo an additional examination, and when confirming the results of the tests, make an appointment for a consultation with an endocrinologist and follow all the prescriptions of the specialist.
Prevention measures
In order to maintain the normative content of the free hormone T3 in the body, it is recommended to exercise regularly, especially swimming and yoga are very useful in this sense. It is desirable to engage in interesting and unbearable work in a pleasant team. It is desirable to add iodized salt to food, especially in areas where groundwater contains little iodine. It is necessary to use more often dairy products, sea kale, any nuts( besides peanuts), sunflower seeds, dried fruits. Also useful are citrus fruits, vegetables, green leaf tea, honey, coarse bread. It is recommended to reduce the consumption of sugar, margarine, fast food, alcohol, canned food, light carbohydrates, smoked products.
