What are thyroid hormones? What hormones does the thyroid gland secrete?

Thyroid hormones.

It is a hormone that is secreted by the thyroid gland and has a regulatory function for the body. In hyperthyroidism.

At that time, the patient will show symptoms such as nervous excitement, temper irritation, palpitation, and hand tremors; But hypothyroidism.

When the patient has symptoms such as cold intolerance, poor appetite, weight gain, and apathy, thyroid hormone is very important to the body, and if the examination finds any abnormalities, it must be supplemented in time under the guidance of a doctor.

Thyroid hormone (thyroxine) is also known as 3,5,3'，5'- Thyroxine (3, 5, 3'，5'-Tet-raiodothyronine (T4) includes total triiodothyronine (TT3), total thyroxine (TT4), free triiodothyronine (FT3), and free thyroxine (FT4). Physiologically, T4 binds to serum thyroxine-binding globulin (TBG). Conjugated T4 cannot enter peripheral histiocytes and can only enter histiocytes to play its physiological role after being transformed into FT4.

Thyroid hormones include total T3, total T4, free T3, and free T4. Total T3 and total T4 are formed after the combination of thyroid hormones and proteins, while free T3 and free T4 really play a role in the blood. When free T3 and free T4 are exhausted, the total T3 and total T4 proteins become free again, which ensures that the free thyroid hormone level of the body is within a relatively constant value.

Elevated thyroid hormone levels, especially free T3 and free T4, can occur in patients with diffuse goiter with hyperthyroidism, as well as in the transient hyperthyroidism of acute thyroiditis and subacute thyroiditis. It can also be seen in hyperthyroidism due to a central disorder, which is called pituitary hyperthyroidism, which is very rare and generally unimportant.

Elevated thyroid hormone levels are usually due to diffuse goiter with hyperthyroidism, which is caused by the body's autoimmune disease, which uses the thyroid gland as an antigen to produce autoantibodies. In addition to elevated thyroid hormone levels, there may be elevated antibodies, including globulin antibodies, microsomal antibodies, and thyroid-stimulating hormone receptor antibodies, which should be given the correct ** in the presence of hyperthyroidism.

The main function of the thyroid gland is to synthesize and secrete thyroid hormones. The thyroid gland is located in the front of the neck, like a butterfly or shield, the size of a thumb, and the texture of the lips to the touch, and its main function is to synthesize and secrete thyroid hormones. Thyroid hormones help use and store energy.

If thyroid hormone is deficient, it will cause low metabolism of the body, such as sensitivity to cold, edema, and even slow heartbeat, sluggishness, memory impairment, slowing down heartbeat and gastrointestinal peristalsis slowing down, not wanting to eat, defecating and even constipation.

The thyroid gland is innervated by the pituitary gland, and if the thyroid gland is not functioning properly, the pituitary gland secretes thyroid-stimulating hormone, which enlarges or produces more thyroid hormones. By measuring the size of the thyroid ultrasound and knowing the level of thyroid hormones, it helps to know if the thyroid gland is working properly. If the thyroid is understated, levothyroxine sodium replacement** can maintain normality for a long time, which is safe and effective.

If the thyroid gland is synthesized and secreted a large amount of thyroid hormone due to various reasons, the body will have symptoms of hypermetabolism, such as heat intolerance, excessive sweating, hand tremors, and palpitation, which is completely opposite to hypothyroidism.

The thyroid gland secretes thyroid hormones, and the thyroid gland uses iodine as a raw material to synthesize and secrete thyroid hormones, which are innervated by the hypothalamus and pituitary gland, and the synthesized thyroid hormones first enter the bloodstream and are transported to various organs of the body, such as the heart, lungs, digestive system and brain, and thyroid hormones help to utilize and store energy.

The most important role of thyroid hormone is that before birth, the formation and development of the fetal brain are inseparable from thyroid hormones, and the maturation of bones also needs thyroid hormones. Thyroid hormones and thyroid-stimulating hormone secreted by the pituitary gland are measured to help determine whether the thyroid gland is working properly.

The thyroid gland mainly secretes thyroxine. The thyroid gland has the function of synthesizing, storing and secreting thyroxine, which is a class of iodine-containing iodotyrosine-containing organically bound iodine, including tetraiodotyrosine (T4) and triiodotyrosine (T3), which is synthesized and combined with thyroglobulin and stored in thyroid follicles.

1.Thyroxine accelerates the utilization of oxygen by cells throughout the body, accelerates the decomposition of proteins, sugar water compounds and fats, comprehensively improves the body's metabolism and increases calorie production.

2.Thyroxine promotes the growth and development of the human body, mainly affecting the brain and long bones after birth.

3.Thyroxine can also affect the metabolism of water in the body, such as hypothyroidism, which can cause myxedema.

What you want to ask is what hormones the thyroid gland can secrete?

The thyroid gland mainly secretes thyroid hormones, and its main role is to regulate the body's metabolism; The thyroid gland also produces calcitonin, which regulates the balance of calcium in the body; It can also regulate the rate of using the heat and energy produced by the body, make proteins, regulate the body's sensitivity to other hormones, and affect growth and development. If the thyroid secretion is abnormal, the physical and mental health will be seriously affected. If the thyroid gland secretes a little more, it will feel nervous, irritable, etc.; If you secrete too much, you will be very nervous, sweating, trembling, indigestion, insomnia, and lose weight rapidly, which is called hyperthyroidism.

On the contrary, if the thyroid secretion is slightly less, it will be easily tired, drowsy, cold hands and feet, etc., which is called hypothyroidism; If the secretion is too low, the movement is slow, the pulse and heart beat are slow, the body temperature drops, the cold is afraid of cold, the speech is slurred, the feeling is sluggish, and the body is fat.
