The table of TSH norms by age in women will help determine the possible deviation of the hormone level from the norm, which is important for understanding the processes occurring in the body with various pathologies.
Hormonal background is the most important component of human health. Hormones control the functioning of all organs and systems, metabolism. A special regulator is responsible for the production and concentration of various hormones - thyroid stimulating hormone (TSH, thyrotropin, according to the international classification - TSH, thyroid stimulating hormone), produced by the anterior pituitary gland.
The norm of TSH in women fluctuates with age; In men, its blood content changes with age, but during the mature period of life it is generally stable, in women it changes depending on age and condition (for example, during pregnancy). In both sexes, hormone production undergoes daily fluctuations..
To control the hormonal background, it is recommended to regularly take tests, especially in the case when there is reason to suspect an imbalance.
The norm of the hormone TSH in women Reference values \u200b\u200bhave been developed (t. those according to which the data obtained are assessed) the content of thyrotropin in the blood for each age group of women.
Age category.
Normal TSH readings (unit of measurement - ?IU / ml).
0 to 3 months.
1.1-16.8.
From 3 months to 5 years.
0.4-6.5.
From 5 to 14 years old.
0.4-0.5.
Up to 25 years old.
0.6-4.5.
26-50 years old.
0.4-4.0.
After 50 years.
0.4-4.5.
In different medical laboratories, indicators may differ.
According to the above data, the highest level of thyroid-stimulating hormone is observed in newborn children.. Then it gradually decreases, but until 5 years old it remains high compared to adult indicators - this is a normal condition and does not cause concern among doctors. After 5 years, the production of thyrotropin decreases, from the moment of puberty of the girl, the concentration of TSH in the blood corresponds to normal adult values. Outside of pregnancy, strong fluctuations are not observed until the beginning of the preparation of the body for menopause, after which the TSH content in the blood increases slightly.
A significant increase or decrease in the level of thyrotropin in the blood (above or below the reference values) indicates a pathology and requires an examination of the woman by an endocrinologist.
TSH levels during pregnancy Pregnant women undergo significant hormonal changes in the body.. The endocrine system begins to work harmoniously on a single task - to preserve the fetus and ensure its normal development.. At each stage of pregnancy, the body creates special conditions for this, as a result, TSH fluctuations in different trimesters are noted:.
Term.
Normal thyroid-stimulating hormone level (unit ?IU / ml).
Up to 12 weeks (I trimester).
0.1-0.4.
12-24 weeks (II trimester).
0.3-2.8.
24-40 weeks (III trimester).
0.4-3.5.
The pregnancy hormone hCG (human chorionic gonadotropin) increases the production of T3 and T4, which, thanks to the feedback system, causes a decrease in TSH values. While maintaining high rates in the first trimester, it is necessary to undergo an examination by an endocrinologist, since in this case the fetus may be in danger.
In some women, the level of TSH during pregnancy decreases to a minimum value, when measured, the indicator may be zero.. This indicates a multiple pregnancy..
When carrying one child in the third trimester, the hormone may slightly exceed the pre-pregnancy rate, since the baby has already formed its own thyroid gland and has begun to produce hormones necessary for its growth and development.
Significant hormonal fluctuations raise concerns among doctors. It is important to schedule additional studies on time to establish the causes of violations and carry out correction..
Elevated thyrotropin in pregnant women High TSH levels in the first weeks of fetal formation are most dangerous, since at this time the fetus is very vulnerable.
An increase in thyrotropin in pregnant women can be manifested by the following symptoms:.
poor appetite;
increased irritability;
fatigue, lethargy;
nocturnal insomnia combined with daytime sleepiness;
intense weight gain.
However, this condition is typical for many pregnant women and does not always speak of pathology, so one should not rush to conclusions.. If you suspect hormonal disorders, you must contact a specialist and donate blood for analysis.
Decreased thyrotropin in pregnant women A critically low value of thyroid-stimulating hormone also has a negative effect on the child in singleton pregnancy.
This can lead to delayed child development and other pathologies..
Symptoms of low TSH in pregnant women:.
headaches;
high blood pressure;
bulging eyes;
elevated temperature;
sudden weight loss;
swelling of the lower extremities.
To restore hormonal balance in pregnant women, the help of an endocrinologist and obstetrician-gynecologist who leads the pregnancy is required. Self-medication is unacceptable.
