Is low thyroid hormone serious?

If you find that your thyroid hormone is low during the examination, you should pay attention to it. At this time, you may have serious hypothyroidism. If this continues for a long time, it will definitely affect people's health. Therefore, you need to do appropriate treatment when it is discovered in the early stage. You can take some drugs to promote the development of thyroid hormone to avoid this situation.

For hypothyroidism: Initially, take no more than 15-30 mg per day orally, then gradually increase to 90-180 mg per day. After the condition stabilizes, switch to a maintenance dose of 60 to 120 mg per day, and select a dose suitable for long-term use.

For cretinism: The dosage varies with age: 8 to 15 mg per day for children under 1 year old, 20 to 45 mg per day for children 1 to 2 years old, and 30 to 120 mg per day for children over 2 years old, divided into 3 doses.

Simple goiter: Initially, intramuscular injections are given to relieve symptoms. After relief, switch to oral administration. The course of treatment is generally 3 to 6 months. : It has the effect of promoting general tissue metabolism, improving nerve excitability and physical development. Used to treat hypothyroidism, myxedema and cretinism, etc.

It is an amino acid derivative that promotes metabolism and development, increases the excitability of the nervous system, accelerates breathing and heart rate, and increases heat production.

Secreted when cold or stressed.

When people encounter danger and are emotionally nervous, the hypothalamus will be stimulated to release thyrotropin-releasing hormone. The increased concentration of this hormone in the blood will act on the pituitary gland to promote the release of thyrotropin, that is, increase the content of thyrotropin in the blood. Thyrotropin further acts on the thyroid gland, increasing the secretion of its glandular cells, that is, secreting a large amount of thyroid hormone.

(It generally does not directly increase blood sugar.)

It works synergistically with growth hormone in terms of growth and with adrenaline in terms of temperature regulation.

The growth-promoting effects of thyroid hormones are most evident during infancy, with the greatest impact within the first five months after birth. It mainly promotes the growth and development of bones, brain and reproductive organs. Without thyroid hormone, the pituitary GH cannot function. Moreover, when thyroid hormone is deficient, the pituitary gland's production and secretion of GH also decreases.
