T3 hyperthyroidism is suspected, pending confirmation and treatment

If the examination is confirmed by hyperthyroidism, the main thing is to look at the TSH value in the thyroid function, if it is lower than the normal value, it is likely to be hyperthyroidism. In addition, it is necessary to do a color ultrasound examination. If you only do a test to confirm the diagnosis, as long as it is a public hospital, it is okay.

The so-called T3 hyperthyroidism refers to the clinical manifestations of hyperthyroidism, and the experimental examination only increases the serum T3, while the serum T4 is normal. It is more common in women and young adults. The clinical presentation is the same as that of common hyperthyroidism, but the disease is milder and can be seen in the early stages of diffuse, nodular or mixed goiter, so that T3 hyperthyroidism is not strictly a stand-alone condition but only a stage in the course of hyperthyroidism.

Diagnosis of this type is based on: clinical symptoms and signs of hyperthyroidism; T3 is elevated, T4 and free T4 are normal; The thyroid uptake rate of 131i is normal or elevated, but cannot be suppressed by T3; The thyrotropin-releasing hormone test is normal, and serum thyroid-stimulating immunoglobulin is persistently elevated. Wang Xue, the consultation experts of Nanjing Jiakang Hospital, are good at ** hyperthyroidism, T3 hyperthyroidism, Hashimoto's hyperthyroidism, hyperthyroidism during pregnancy, hyperthyroid heart disease, primary hypothyroidism, subclinical hypothyroidism, post-iodine hypothyroidism, drug-induced hypothyroidism, subacute thyroiditis and other thyroid endocrine problems.

The vast majority of patients with hyperthyroidism have elevated serum free T3 and free apostle T4 levels, and only a few patients with hyperthyroidism have only elevated serum FT3 levels and blood FT4 levels within the normal range, which is called T3 hyperthyroidism. It is more common in patients with iodine-deficient goiter, toxic thyroid adenoma, and toxic nodular goiter. The clinical manifestations of T3 hyperthyroidism are mild, and the time required for the FT3 level to fall to normal after blood stockings with antithyroid drugs** is relatively short.

Some people think that T3 hyperthyroidism is a relatively mild form of hyperthyroidism, but if T3 hyperthyroidism is caused by toxic thyroid adenoma or toxic nodular goiter, antithyroid drugs alone cannot be used, but surgery or isotopes are required.

Hello, in general, the symptoms of hyperthyroidism are mainly caused by an increase in the secretion of thyroid hormones, thyroid hormones, including T3 and T4. Usually we see an increase in T4, if it is only an increase in T3, it is considered to be T3 hyperthyroidism. The general symptoms are the same, mainly hypermetabolism.

After you have hyperthyroidism**, T3T4 is normal, and TSH is still low, which is a manifestation of subclinical hyperthyroidism, that is, hyperthyroidism is not completely controlled, and you still need to continue to take medication, and you should not stop the drug prematurely.

In the process of hyperthyroidism**, because the thyroid hormone of the pituitary gland responds late, TSH returns to normal late, therefore, if the TSH measurement value is still low, regardless of whether T3, T4, FT3, and FT4 are normal, it should be judged that hyperthyroidism has not been controlled, and it is recommended to continue taking medication under the guidance of a doctor, reduce or maintain**.

The so-called T3 hyperthyroidism refers to the clinical manifestations of hyperthyroidism, and the experimental examination only increases the serum T3, while the serum T4 is normal. The disease was first discovered in 1957, and in 1968, Hollander proposed the official name of T3 hyperthyroidism, and its incidence was reported abroad to account for 4%, domestic reports accounted for about 7%, and the incidence of T3 hyperthyroidism in iodine-deficient areas was relatively high, and some people reported to account for 30% of the total number of hyperthyroidism. It is more common in women and young adults.

Signs and symptoms of hyperthyroidism.

T4 and FT4 are normal or low, while T3 and FT3 are elevated.

Hypersensitivity TSH drop or TRH stimulation test shows a low-flat curve.

4)**: Same as common hyperthyroidism, generally with drugs**; ** is less likely than in common hyperthyroidism. Hyperthyroidism is the opposite of T3 hyperthyroidism, in which some patients have only T4 elevation but T3 is normal, called T4 hyperthyroidism.

It is more common in older people or patients with chronic medical conditions, and was first proposed in 1978. T4 hyperthyroidism is more common in two conditions: Iodine hyperthyroidism.

About 30% of patients with iodine hyperthyroidism have normal T3 but elevated T4, which may be due to the high dose of iodine load causing the thyroid gland to synthesize T3 and T4 in large quantities, but in fact T4 synthesis and release more than T3, resulting in hyperT4emia. Hyperthyroidism with chronic complications.

The ability to convert T4 to T3 in the peripheral blood of such hyperthyroid patients is weakened or lost, and the T3 in the body can only be directly synthesized by the thyroid gland, so although T4 is elevated, T3 is normal or even decreased. In addition, due to the inhibition of 5' monoiodeiodinase, the RT3 in the blood of such patients is abnormally elevated, and when the chronic disease recovers, the RT3 decreases and the T3 rises. It should be noted that although some long-term chronic patients do not have hyperthyroidism, they may occasionally have an increase in T4 during the course of the disease, which needs to be distinguished from T4 hyperthyroidism, which can be judged according to the level of TSH.

Most patients with hyperthyroidism have elevated T3 and T4 in their blood, but a small number of patients have only T3 elevated and T4 is normal, which is called T3 hyperthyroidism. The disease was first reported by Maclagan in 1957. Reported incidence is mixed, accounting for 3% to 20% of hyperthyroidism; It has been suggested that older patients are more likely to occur.

It is recommended that patients go to the hospital in time to find out the situation, and the hospital will give a corresponding plan according to the different conditions of each patient.
