The normal TSH levels in women by age: table

TSH what is it? The real causes of ill health can determine the results of laboratory tests for hormones, which can clarify a lot a qualified physician, including the increased thyrotropic hormone — TSH. Especially important normal TSH in women.

Medical statistics indicate that the female is much more common pathology of the thyroid gland and elevated TSH than in the male.

The norm are the following indicators:

  • TSH norm in women is 0.4–4.2 mu/l;
  • the males – 0,4–4,0 mu-l.

Thyroid-stimulating hormone


The necessary material for the normal functioning of the thyroid gland is iodine, which comes from food or by intake of certain medications. From it synthesized the hormones T3 and T4. These hormones are important for the body because they affect the following processes:

  • stimulating the thought process and psychological state;
  • the motor function of a person;
  • blood pressure;
  • the work of the heart;
  • saturation of cells with oxygen and protein.

What is TSH? This thyroid hormone which is responsible for the heart, circulatory system, vascular system and skin. Provides a complete reproductive system, reproductive organs, gastro-intestinal tract. Rate the content of hormone in the body ensures healthy development and functioning of the whole organism, coordination of work of all the bodies absorption of vitamins and minerals. Accordingly, the hormone deficiency leads to disturbances in the nervous system and mental state of the person, and also indicates the presence of the disease.

Note that the hormones TSH and T4 and T3 are interconnected and during the laboratory tests, it is necessary to consider the level of all three hormones.

If you suspect endocrinologist or treating physician for diseases of the endocrine system, is assigned to the analysis of TSH. In addition, the study on the level of TSH in the body can be appointed in the following diseases:

  • cardiac arrhythmia;
  • depression;
  • infertility;
  • decreased libido.

Note that for accurate results, and determining the level of TSH in the body should be tested several times. This is due to the fact that the rate changes during the day, that is depends on what time of day was produced blood sampling. In addition, indicators of thyroid-stimulating hormone depend on factors such as age, biological sex, presence of chronic diseases and other.

How to pass a blood test for TSH?

It is recommended to hand over the analysis on TTG in the morning on an empty stomach. At this time, the concentration of thyroid stimulating hormone is at its highest. The result can be influenced by food, therefore it is recommended to take a blood test TSH fasting. In the evening you should also pay attention to the diet and used products. It is advisable to avoid heavy and spicy foods.

From the consumption of alcoholic beverages should be discontinued one day prior to analysis. It is also preferable not to take drugs, with the exception of vital medicines. And should avoid emotional stress and heavy exercise.

The high rate of TSH

If the result of the TSH is elevated, what does that mean? This shows the failure in the endocrine system, namely about the problems in the thyroid gland and reduce its function.

Symptoms when the hormone TSH is elevated, the first time, as a rule, is not observed. No ailment is not observed, and indicators of other hormones T3 and T4 can be normal.

The absence of treatment, the body lets you know that something is wrong. Suggest the following characteristics of high level of TSH:

  • the addition of extra pounds (a set of excess weight);
  • the dramatic reduction in weight;
  • when metabolic disorders a person feels constantly cold and chilliness;
  • the observed yellowing of the skin;
  • dry and brittle hair and nails;
  • the puffiness that can occur around the eyes;
  • quick General fatigue;
  • sleep disturbance;
  • drowsiness;
  • lowering the memory;
  • speech disorders;
  • heart failure;
  • anemia;
  • the manifestation of nausea and lack of appetite;
  • the tendency to constipation, bloating;
  • disorders of the menstrual cycle.

Thus, to suspect changes in the thyroid gland and can in appearance, mental-emotional indicators, cardiovascular manifestations and the digestive system.

The appearance of any symptom of the disease, should be screened and begin treatment. When late begun treatment can develop following serious symptoms pointing to thyroid disease:

  • serious difficulties with pronunciation;
  • the thyroid gland increases in volume;
  • the neck has a reddish or bluish hue;
  • there is a feeling of discomfort in the neck and sometimes its deformation.

The reasons for the increase in TSH

Among the reasons affecting the increase in the level of thyroid-stimulating hormone, there are primary caused by the thyroid disease; and secondary – associated with dysfunction of the pituitary and hypothalamus:

  • the higher the level of TSH is primarily a dysfunction of the thyroid gland. Mainly caused by lack of iodine in the body;
  • severe mental character;
  • malfunction of the adrenal glands;
  • excessive physical activity. For this reason, an increased level of TSH is frequently observed in athletes;
  • prolonged and uncontrolled hormonotherapy drugs.

First of all, on increase of level of TSH influences the thyroid gland. The improper functioning and development of thyroid cancer depend on the following factors:

  • surgical intervention and removal of the thyroid gland;
  • pregnancy and childbirth;
  • taking certain types of medication;
  • treatment with iodine (radioterapia);
  • insufficient and improper working of the adrenal glands;
  • increased levels of prolactin.

Increase in TSH levels in women

The female is very important to control the level of this hormone in the body. Is it hormonal changes body during pregnancy, birth and subsequent lactation, and during menopause. During these periods, the rate of thyrotropin changes.


The proper functioning of the endocrine system affect the normal pregnancy and child development. For this reason, expectant mothers are often assigned a diagnostic study on hormones.

When planning pregnancy, women should monitor the hormone levels of TSH, as its allowable deviation from the norm in either direction can lead to deviations in the development of the fetus and complications of pregnancy. The normal thyroid-stimulating hormone in women will be the key for proper formation of the fetus and birth of a healthy child.

To adjust the TSH level in a pregnant women need constant medical supervision, commissioning tests and medication therapy.

However, do not immediately panic when you change the level of the hormone TSH. Note that during this period a slight increase in TSH above normal is considered a physiological feature of an organism of the expectant mother and trimester of pregnancy, and not a deviation from the norm. In addition, the normal content in the body, TSH levels are distributed across trimitra as follows:

  • 1 period is 0.3 to 4.5 mu/l;
  • 2 period of 0.5–4.6 mu/l;
  • 3 period of 0.8–5.2 mu/L.

Low levels of the hormone

If the hormone TSH lowered that this could mean? In the case of low thyroid-stimulating hormone, there is a disruption in the thyroid. In addition, the low TSH could be a sign of the presence of benign thyroid tumors, meningitis, encephalitis and other diseases. The lack of substance in women causes constant headaches, chronic fatigue, ucashenie pulse, the appearance of the swelling on the face, disruptions of the menstrual cycle.


Treatment appointed strictly physician, no self-treatment is not allowed. It is necessary to accurately establish the diagnosis and identify the causes that affect the deviation of the level of the hormone from the norm. The course of treatment is chosen individually, taking into account the degree of development of the disease, concomitant diseases, presence of contraindications and the patient’s condition.

Thus, the course of treatment the doctor prescribes on the basis of:

  • the results of blood tests (low TSH);
  • inspection and palpation of the thyroid gland;
  • the medical history of the patient.

The doctor will prescribe medication depending on the degree of dysfunction of the thyroid gland.

To compensate for the shortage of thyroid hormones in the body to help preparations of thyroxine. When the concentration of thyroid hormones level normal, the substance itself will begin to decline to the desired level. If there will be a surplus of the drug, it is necessary to decrease the dosage. In order to prevent the overabundance of synthetic drugs, it is necessary to periodically monitor the level, handing over laboratory tests.

It is important to strictly follow your doctor. The course of treatment needs to be properly drafted because the wrong treatment of elevated levels of thyroid-stimulating hormone can lead to a decrease in the rate, reaching even zero. As high level and low undesirable substances the results of the analysis.


Be aware that if the late diagnosis of disease or refusal of treatment may have serious consequences, up to Oncology. In the case of early diagnostic tests and timely treatment can lead a normal life.

After the taken the right course of treatment the patient can lead a normal life. However, note that in some cases will require a permanent taking of drugs, so as not to cause complications or occurrence of relapse. However, the disabled person is not affected.

The most serious consequences are observed during pregnancy:

  • pathology in fetal development;
  • the likelihood of miscarriage;
  • preeclampsia second half of pregnancy;
  • detachment of the placenta.

In addition, the high level at least will impact on the overall health and mood. One of the more serious consequences may be disturbed metabolism, developing hypertension and diabetes. The most serious complication is the development of cancer of the thyroid gland.

Controlling and maintaining normal hormone levels, you guarantee the well-being and overall health.
