TSH - what is it: the norm in women by age: table. TSH and T4 are normal: indicators of the thyroid gland during pregnancy. Thyroid-stimulating hormone increased or decreased: what does it mean?

This article lucidly explains what TSH is, what tests can be taken to determine the indicators of this secretory substance, and because of which there may be deviations from normal indicators.

The emotional mood of a woman is often associated with fluctuations in hormone levels. And this is true if the norm of the pituitary gland is increased or, conversely, lowered.

  • But it should be remembered that such deviations are not always associated with severe emotionality and other intense mood disorders.
  • A woman may feel tired during the day, although before that she had a good night's sleep.
  • You can also for a long time unsuccessfully struggle with excess weight, and torment yourself, why can’t lose weight.
  • It is drowsiness, fatigue and excess weight that are often signs of the development of serious abnormalities in the thyroid gland.
  • Therefore, it is important to timely test for the pituitary gland to stop the progression of the disease of an important body system. Read more below.

TTG - what is it?

TSH - secretory substance of the thyroid gland

TTG is an abbreviation of a medical term "thyroid-stimulating hormone". This secretory substance is produced by the pituitary gland, stimulates the synthesis and secretion of thyroid hormones. It is a biologically active substance, the production of which is performed by groups of brain neurons.

TSH and T4: functional features, indicators of the thyroid gland

This secretory substance is very important for the normal functioning of the whole body as a whole.Pituitary hormone responsible for such functional processes of a person:

Human functional processes for which thyrotropic secretory substance is responsible

It is worth noting that T4 in 90% it is responsible for the synthesis of the thyroid gland, ensuring normal metabolism and the full functioning of all organs and systems. The content of the pituitary substance and the subsequent fabrication of thyroxine can be affected by time of day, medication, pregnancy, and so on.

As you can see, many important processes in our body depend on the parameters of the pituitary substance. Therefore, it is important to know its regulatory indicators and take care of yourself. In case of unpleasant symptoms, you should immediately consult a specialist.

TSH analysis: when prescribed, preparation

Delivery of biomaterial at TTG

The process of thyrotropin production is closely associated with the functionality of the thyroid gland and the work of other organs. If there are deviations from the norm, this means that pathological processes develop in the body.

To establish the indicators of the pituitary gland, venous blood is taken from any hand. It is important to prepare for the study, otherwise the parameters of the secretory substance may turn out to be distorted and the picture of the presence of pathologies will be unreliable.

When is a TSH test prescribed?

The document directing for research should be written out by the doctor. Indications for blood donation to the pituitary substance can be as follows:

  • Mental disorders, neurotic conditions, prolonged depression, apathy, causeless irritation, aggressiveness.
  • Pathological hair loss.
  • Infertility, menstrual irregularities.
  • The presence of seals in the thyroid gland - obvious and painful.
  • In children - a developmental delay.
  • Constantly low body temperature.
  • Atrophy of muscle mass and any muscle damage.

Worth knowing: The doctor should prescribe an analysis for the pituitary substance when taking any hormones. Also, if a woman is diagnosed with some kind of autoimmune disease, she should monitor the levels of thyroid-stimulating secretory substance.

Research on antibodies to thyrotropin receptors: why is this needed?

Often, doctors, together with the analysis of the pituitary gland, prescribe a study on antibodies to thyrotropin receptors. What is it for?

The fact is that such antibodies can be a marker of many other serious pathologies. Pituitary hormone receptors perform such a basic task - interaction when creating the coordinated work of all human systems. If one of the organs does not work well, secretory substances in the blood, called antibodies, begin to be produced. They block the secretion of thyrotropin.

Remember: If the level of the pituitary substance decreases, then this entails an increase in the production of other secretory substances. As a result, the pancreas atrophies and other systems begin to function poorly.

Preparation for the study on TSH

Light food before TSH testing

3 days before going to the laboratory in the direction of a doctor, you should do the following:

  • Do not eat heavy foods with a high fat content and do not drink alcohol-containing drinks.
  • Do not engage in a fitness room, on simulators, exclude any other physical activity.
  • The psycho-emotional state should be calm.
  • Do not smoke, do not take any pills, especially hormones, as this may incorrectly show the effectiveness of the study.
  • Do not eat for 12 hours before going to the laboratory.

Biomaterial is taken in the morning on an empty stomach. For 12 hours before this process, you can drink only clean water.

Important: Women should come to the study for thyroid stimulating hormone on the 5th, 6th and 7th day of the menstrual cycle.

If diseases associated with deviation indicators pituitary substances were identified earlier, then the analysis should be taken every 6 months.

Interesting to know: The level of the pituitary substance depends on the time of day. The highest rate will be at night, but on condition that the person is sleeping. If you stay awake at night, then the synthesis of the substance slows down sharply. The lowest hormone levels can be observed in the evening - from 17-00 to 19-00 hours.

Norm TSH in women by age: table

When studying the results of the study, the doctor compares them with the norm. It depends on the age and condition of the woman's body. The measurement of this hormone is carried out in units per volume - honey / l.

Table with TSH norms

Also, the doctor must take into account factors that can affect the health of a woman: existing diseases, the condition of internal organs and the general hormonal background. With age, the indicators of the pituitary substance should decrease. An exception may be the period of pregnancy, lactation. At this time, the background of secretory substances changes naturally.

TSH during pregnancy: normal

As mentioned above, during pregnancy, thyroid-stimulating hormone can be increased in comparison with the usual condition of a woman. Its indicators depend on the trimester:

Each trimester of pregnancy has its own thyrotropic substances

Important: Only the doctor should evaluate the results of the study!

Increase pituitary substance in pregnant women is dangerous especially in the 1st trimester of fetal development, since it is at this time that important baby systems begin to emerge. The most dangerous consequence of such a deviation in the expectant mother is a brain dysfunction in the baby.

It is important to know: Low rates can also lead to the development of various diseases. Therefore, if you are concerned about some unpleasant state of the body, be sure to tell your doctor about it.

You should not make a diagnosis and worry on your own if you think that the indicators are different from the norm, since the general condition of the woman and her body should be assessed, and only an experienced doctor can do this.

Thyroid-stimulating hormone increased or decreased: what does it mean?

Any deviations in the indicators of thyroid-stimulating secretory substances indicate the presence of pathological conditions in the body. It should be understood that if TTG increased, then the thyroid function is reduced, and vice versa - if the level of the pituitary substance is less than normal, then the thyroid function is increased. With what it can be connected, read below.

TTG reduction

If you donate biomaterial to the pituitary gland and it turned out that his indicators are less than normal, then this indicates the presence of one of these diseases:

Diseases that may be associated with a decrease in TSH

A decrease in this secretory substance can be with stress, sudden starvation, or uncontrolled intake of hormone pills.

Remember: Female body systems respond immediately to decline TTG: there are malfunctions in the menstrual cycle, palpitations in the arms and legs, insomnia, the gastrointestinal tract does not work well and speech may even slow down. Therefore, at the first ailments, immediately contact an endocrinologist or gynecologist.

TSH increase

If after the delivery of biomaterial, as a result, you see excess of standard indicators TTG, then you may have one of these pathologies:

Pathology with an increase in TSH

Level TTG may increase also with the following factors:

Factors in which the level of thyroid-stimulating substance may increase

In addition, it is not necessary to exclude genetics to increase TTG. It is worth noting that often the doctor sees such a deviation in the female body and without analysis. The increased thyrotropin indices are indicated by such “signals” of a woman’s body:

  • Thick neck
  • Obvious Obesity
  • Increased sweating

Also, a woman may complain of poor sleep, fatigue and low body temperature.

Tip: If you have any symptoms that indicate problems with hormones, it is important to find a good doctor.

The doctor should correctly diagnose, given that there is a syndrome of euthyroid pathology:

  • With this disease, indicators TTG can both rise and fall.
  • This makes diagnosis difficult, but the doctor can give the correct clinical evaluation only if there are no signs of hypothyroidism.
  • In addition, with such a pathology TTG blood count is significantly elevated.

Lead indicators TTG normal is possible if the main cause is eliminated - the disease that led to this pathology. Self-medication is dangerous to health. Only an experienced doctor should diagnose and treat the disease. Be healthy!
