TSH (thyroid stimulating hormone) plays an extremely important role in the functioning of all systems and organs of the body, it is responsible for the normal functioning of the thyroid gland. And what is the norm of the TSH hormone and under what conditions can deviations be observed?
What is the TSH hormone?
Before talking about specific norms and deviations, it is worth understanding what the TSH hormone is. So, TSH is a special hormone that is produced in the anterior lobes of a certain part of the brain, namely the pituitary gland. He is responsible for how the thyroid gland, which is important for a person, will function. This hormone stimulates the production of two others - T3 and T4, which are responsible for many metabolic processes, as well as for the work of the digestive, reproductive and cardiovascular systems. So it's hard to overestimate the role of TSH in the human body.
TSH hormone: norms
What is the norm of the hormone TSH? It differs by age group. So, for newborns, the value is from 1 to 17 mU / l. In babies not older than 2-3 months, the content of this hormone ranges from 0.6 to about 10, in children older than 2-3 months, the indicator decreases and should be equal toapproximately 0.5-7.1 mU/l. From one and a half to 5 years, the normal value should be about 0.4-6.1 mU / l. In children from the age group up to 14 years, the content of TSH is 0.5-5.1 mU, and in adolescents over 14 years of age (as in adults) it contains 0.5-4.1 mU. During pregnancy, the norm for women decreases and ranges from 0.2-0.4 to 3.4 mU / l.
Deviations from the norm: causes and symptoms
In what cases should I donate blood for TSH, what symptoms should alert me?
1. Hormonal disorders, such as increased prolactin levels.
2. Sudden and spasmodic changes in body temperature.
3. Lack of menstruation in women.
4. Infertility or difficulty conceiving.
5. Goiter.
6. Problems in the functioning of the muscular system.
Now it is worth listing the cases in which the norm of the TSH hormone can be exceeded:
- Postoperative period (for surgical interventions that directly affected the thyroid gland).
- Cancer or tumors of the thyroid gland.
- Tumours of the pituitary gland, in some cases of the lungs, mammary glands.
- Overdose of antithyroid drugs.
- Thyroiditis.
- Intense physical activity.
- Toxin poisoning.
And in what cases will the level of the hormone TSH be reduced?
- If there is a problem with the pituitary gland (cell death or decreased function).
- For Plummer's disease.
- In the presence of benign formations inthyroid area.
- When taking hormonal drugs (especially uncontrolled).
- With stress, depression.
- For toxic poisoning.
Tests
Now you know what the norm of the TSH hormone should be. If you find any alarming symptoms in yourself, you need to take an analysis. This requires special preparation. For example, a week or two before the procedure, you should stop smoking and physical activity, as well as taking hormonal drugs and drugs that affect the direct functions of the thyroid gland. The analysis is given in the morning, on an empty stomach. In conclusion, we can add that if left untreated, serious problems with the thyroid gland threaten, which will significantly undermine all he alth in general.
