Thyroid stimulating hormone (TSH) is a substance (hormone) with an important role in regulating thyroid function. Its blood levels can provide relevant information about the health of the thyroid gland and its function in the body. Checking the level of TSH in the blood is, moreover, a medical investigation often recommended and used in the diagnosis and monitoring of disorders related to the thyroid gland, such as hypothyroidism or hyperthyroidism.

Here is what is useful to know about TSH values ​​so that you can schedule a specialist medical consultation when you think you might have health problems.

The thyroid gland and its role in the body

The thyroid gland is responsible for the production of thyroid hormones, such as T3 (triiodothyronine) and T4 (thyroxine), which are involved in regulating metabolism, growth, development of the body, as well as ensuring other body functions.

The level of TSH in the blood is often used as an indicator of proper thyroid function. For example, when the level of thyroid hormones (T3 and T4) in the blood decreases, the pituitary gland reacts by producing more TSH to stimulate the thyroid to produce more thyroid hormones. On the other hand, when the level of thyroid hormones increases, the pituitary gland reduces the secretion of TSH.

As we learn more here, checking the level of TSH in the blood is recommended in several situations, the most common referring to:

  • routine evaluation of thyroid function: checking your TSH level can provide important information about thyroid function. Abnormal TSH values ​​may indicate hypo- or hyperthyroidism, which requires further investigation and treatment.
  • detection of thyroid disorders: thyroid disorders, such as hypothyroidism (low levels of thyroid hormones) or hyperthyroidism (high levels of thyroid hormones), can affect a person’s health and well-being. Periodically checking the TSH level can help detect these disorders and establish a proper diagnosis.
  • treatment monitoring: people who are diagnosed with thyroid disorders and are receiving treatment, such as taking synthetic thyroid hormones or other therapies, may need regular monitoring of their blood TSH levels to ensure the effectiveness of the treatment and to adjust the dose as needed.

In general, checking the TSH blood level is part of the general health assessment and may be recommended as part of a routine medical examination or when problems with thyroid function are suspected. It is important to see a doctor to interpret the results and to manage any thyroid health problems or other symptoms you may be experiencing at any given time.
