What are the causes of high thyroid hormone

If the thyroid hormone is too high, it will often induce hyperthyroidism in patients, which is quite harmful to patients and often leads to bad mood, psychological problems, eating a lot but being thin. There are many reasons for high thyroid hormone levels, which are mainly related to problems with the secretion of thyroid-stimulating hormone, such as pituitary tumors, hypopituitarism, etc.

1. Primary hypothyroidism

The main causes of high thyroid-stimulating hormone are common in primary hypothyroidism, thyroid-stimulating hormone-secreting pituitary tumors, hypopituitarism, and the recovery period of subacute thyroiditis.

2. Thyroid stimulating hormone (TSH):

Its main function is to control the thyroid gland. It can promote the production of thyroid hormones and the release of produced thyroid hormones into the blood. It also plays an important role in the growth and metabolism of the thyroid gland itself. Changes in serum TSH concentration are the most sensitive indicator of thyroid function.

3. Thyroid hormones stimulate adrenal cortex function

It can cause adrenal hypertrophy, and thyroid removal can cause adrenal atrophy. When thyroid-stimulating hormone is too high, systemic metabolism is hyperactive, cortisol degradation is accelerated, and urinary 17-hydroxycortisol excretion increases, causing hyperthyroidism. When thyroid hormone is too low, synthesis is reduced.

4. Secretion of the pituitary gland

Thyroid-stimulating hormone is a glycoprotein that is secreted and released by the pituitary gland in the brain. Its main functions are: promoting the growth and development of the thyroid gland and regulating the synthesis and secretion of thyroid hormone. It can stimulate the thyroid gland to synthesize and secrete thyroid hormones, but if the thyroid gland has been damaged, it will not have this effect.

What happens if the thyroid stimulating hormone is too high? The above is an introduction to the relevant content about high thyroid stimulating hormone. After understanding what this disease is, you can better prevent thyroid disease and help maintain your physical condition. In fact, thyroid hormone is a very important hormone in our human body, which is used to help the human body grow, develop and metabolize better. Once the secretion of thyroid hormone in the human body is too high or too low, it can easily lead to some serious thyroid diseases in patients.
