What causes hypothyroidism?

An underactive thyroid does not cause tachycardia! Your symptoms also rarely happen! Asthma can't be sure! Low thyroidism is autoimmune and impairing. It can also be that the thyroid gland is destroyed! Iodine overdose! I've taken antithyroid medicine! FYI!

Upstairs, hello, I would like to add, that's what the doctor said, and prescribed a box of sodium left thyroid tablets. Say that a small dose of oral half a tablet every 2 days, do I need any other tests?

You are obviously mild hyperthyroidism, low thyroidism will not have the symptoms of tachycardia and high TSH, are you sure it is hypothyroidism?

1.Congenital hypothyroidism: a hereditary disorder, but its genetic characteristics are not well understood, often familial, and siblings may develop the disease at the same time.

In most cases, partial thyroid hypoplasia is present, and radioisotope scans may reveal residual thyroid tissue in the neck, sometimes ectopic thyroid gland. Occasionally, the mother's autoimmune disease, 131 i** or other harmful substances can cause the fetus to develop a thyroid gland that is impaired.

2.Goiter enlargement: It is mostly hereditary and is called familial goiter large cretinism. Caused by abnormalities in the synthesis or metabolism of thyroxine. Anomalies can occur in 8 different links, but some defects are only one. Two families have reported on it.

1) Disorder of iodine uptake or transport by the thyroid gland: It may be a defect in the enzyme that allows iodide to enter the cell"Iodine pumps"Abnormal function, decreased iodine uptake and salivary iodine plasma iodine ratio.

2) Iodine organic defect: peroxidase deficiency makes the thyroid gland unable to convert inorganic iodide into organic iodine, and the perchlorate excretion test is abnormal. There are many types of it, among which those who cause complete iodine organic dysplasia can produce cretinism, but do not cause deafness; In the absence of incomplete organic defects of iodine, goiter and deafness appear, but there is no intellectual disability (pendred syndrome).

3) Iodide tyrosine coupling defect: due to the defect of complexase, thyroxine synthesis disorder is caused, and urinary excretion is increased at 131 i, 4) Deiodine disorder: the reuse of iodine is hindered by the defect of deiodarinase, and the urinary excretion of iodid tyrosine marked by 131 i can be seen.

5) Abnormal thyroglobulin metabolism: thyroglobulin synthesis disorder and abnormal production of iodide protein. They are not able to be deiodized and are excreted in large quantities in the urine, resulting in increased iodidine in the urine and abnormal proteins in plasma chromatography.

6) Difficulty in thyroxine secretion: the proteolytic enzyme of macrophage cytoplasmic granules is defective, resulting in the decomposition of thyroglobulin and the release of T3 and T4 disorders.

7) The thyroid gland does not respond to thyroid-stimulating hormone (TSH): very rare, the thyroid gland is not enlarged, the aspiration 131i test is normal, the TSH is increased but the biological activity is normal, and the in vitro thyroid tissue metabolism test also does not respond to TSH.

8) The surrounding tissues do not respond to thyroxine: the nuclear receptor of the cell is abnormal, so that the thyroxine cannot play its physiological role.

It's your thyroid function, which isn't as active right now. It should have directly affected your digestive system. In other words, this may be the way your indicators should be on a slippery slope. This should be okay.

There are many reasons for hypothyroidism, including the following. 1. It may be caused by autoimmune diseases, such as Hashimoto's thyroiditis. 2. It may be caused by certain drugs.

Third, it may be caused by insufficient iodine intake. Fourth, it may be caused by thyroid enlargement and thyroid tumor. 5. It may be caused by thyroid surgery.

Patients with hypothyroidism may experience symptoms such as paleness, dryness, memory loss, unresponsiveness, abdominal distention, constipation, etc., and patients can use thyroid tablets or levothyroxine sodium tablets.

There may be less sweating.

There is also a fear of cold.

And a lot of people usually experience myasthenia gravis, all due to their own underactive thyroid. Moreover, some of these situations will affect their own daily life, and once we have such problems, it will expose us to a lot of dangers. At this time, we must pay special attention, and if such symptoms occur, we must go to the hospital for timely treatment.

The symptoms are relatively few, but the patient is very easy to get tired, and can not be interested in doing anything, the body is particularly prone to fatigue, lack of concentration, and sleep will be particularly poor, but very drowsy, weight will increase, and there will be edema, if it is a woman, the menstrual flow will be particularly less, the menstrual cycle will become longer, and the heart rate will also slow down, which are all manifestations of hypothyroidism.

First of all, these people will have visual fatigue, and they will also be very afraid of cold, and then they will also have constipation, and at the same time, they will be more fragile, ** and relatively dry, and they are also very slow when they move, and their menstruation is also very irregular.

First of all, it will show some symptoms such as chills and fatigue, and there will also be some conditions such as sluggish expression and hoarseness, and there will also be rough phenomena, which will also lead to endocrine disorders or menstrual disorders, and severe patients are likely to coma.

Fatigue and a great fear of cold may lead to heart failure, myxedema, and coma.

It is often very weak, and has no energy, is often afraid of the cold, and always has no extra strength, which will also affect the intelligence.

Common causes are: after a large thyroidectomy, thyroiditis, pituitary gland disease, etc.

Hello, the causes of hypothyroidism are related to autoimmune damage, thyroid destruction, iodine overdose, and antithyroid drugs.

Hypothyroidism is an endocrine disease that can damage all systems of the body, and hypofunction can cause decreased gastric acid secretion in the digestive system, reproductive system, and irregular menstruation and even infertility in women.

1) Hypothyroidism can easily lead to various serious complications, such as premature ovarian failure, heart disease, hyperlipidemia, hypertension, diabetes, etc.

2) Special features: pale and sallow, puffy face, dull eyes, swollen eyelids, indifferent expression, few words, hoarseness, and slurred speech.

3) Reproductive system: hypothyroidism can lead to habitual miscarriage, infertility, menstrual disorders, edema, and in severe cases, it can also lead to coma in women.
