What is measured in the thyroid TSH test?
Thyroid TSH test
The thyroid plays a crucial role in the body's metabolism and influences various bodily functions. The pituitary gland produces thyroid-stimulating hormone (TSH), which stimulates the thyroid to secrete thyroxine (T4), a precursor to triiodothyronine (T3). It's important to know that tyrosine and iodine are essential for thyroxine production.
Detecting an imbalance in thyroid function
Hypothyroidism is characterized by insufficient production of T3 and T4, leading to symptoms such as fatigue, cognitive impairment, and weight gain. In contrast, hyperthyroidism is caused by an overproduction of these hormones. Hypothyroidism is the most common form and significantly impacts physical and mental health.
Key symptoms of hypothyroidism:
- Constant fatigue and lack of motivation
- Unusual sensation of cold
- Depression
- Unexplained weight gain
- Slow pulse
- Dry skin and brittle fingernails
- Hair loss
- Memory problems
The crucial role of TSH determination
Our TSH test for the thyroid was developed to detect elevated TSH levels, which could indicate a possible thyroid disorder. A TSH level above 5 IU/ml indicates an underactive thyroid and warrants further medical examination.
Thyroid function explained
TSH also regulates the thyroid hormones T4 and T3. These, in turn, control TSH production via a feedback mechanism. This balance is important for maintaining an efficient metabolism and determines how the body burns calories and metabolizes fat. Hypothyroidism therefore leads to a slower metabolism.
Further effects of thyroid health
In addition, an underactive thyroid can also affect other endocrine systems, such as the ovaries and adrenal glands. Often, hypothyroidism is accompanied by intestinal inflammation. This can impede the body's detoxification and make it difficult to eliminate toxins.
Possible causes of hypothyroidism
There are many factors that can lead to hypothyroidism, including insufficient production of thyroid hormones, iodine deficiency, genetic predisposition, chronic inflammation, and hormonal changes during pregnancy and menopause.
Understanding thyroid health is important, and our Thyroid TSH test provides a convenient and reliable starting point for this exploration.
