What exactly causes hypothyroidism?

Hypothyroidism refers to a disease caused by insufficient thyroid synthesis or secretion function due to various reasons, and is clinically characterized by low metabolic function and myxedema, which belongs to the category of deficiency in traditional Chinese medicine. The prevalence is about 1%, and it is more common in women. Hypothyroidism can be caused by dysfunction of the thyroid gland, pituitary gland, and hypothalamus.

Endemic goiter is hypothyroidism caused by insufficient iodine in the diet.

Hypothyroidism affects many aspects of the patient, especially the memory of the patient. Patients may have sluggish thinking, difficulty concentrating, and memory loss because they have the disease; Different types of symptoms such as weight gain.

Causes of hypothyroidism include drug-induced hypothyroidism, post-surgical hypothyroidism, post-iodine-131** hypothyroidism, idiopathic hypothyroidism (unexplained hypothyroidism), and hypothyroidism after pituitary or hypothalamic surgery.

The clinical symptoms of the thyroid gland are varied, such as: fatigue, cold intolerance, weight gain, memory loss, unresponsiveness, drowsiness, constipation, thinning hair, bradycardia, anemia, dyslipidemia, anorexia, bloating, constipation, etc.

It is recommended that you go to a local hospital to take blood to check the three indicators of FT3, FT4, and TSH, if the first two items are decreased and the third one is elevated, hypothyroidism is more likely. In addition, the blood routine can be improved to determine whether there is anemia, blood biochemistry to determine whether there is abnormal blood lipids, thyroid B ultrasound excretion, and thyroid organic lesions. Obtaining conclusive examination data can then confirm the diagnosis, the disease can be **, and ** the method is mainly oral medication to supplement thyroxine, do not worry and cranky.

Hello, hypothyroidism may be caused by congenital thyroid hormone deficiency, or it may be caused by surgery or long-term dietary iodine deficiency. It is recommended to go to the hospital in time for ** is the best.

Hypothyroidism, or hypothyroidism for short, is a systemic hypometabolic syndrome caused by insufficient production of thyroid hormones or weakened action of thyroid hormones due to various reasons. Hypothyroidism is due to an autoimmune disease.

Hypobolic diseases caused by low production of hormones by the thyroid gland due to various reasons such as drugs and surgery, or due to impaired thyroid hormone utilization.

Hypothyroidism is often insidious and has a long course of disease, and many patients lack specific symptoms for a long time. As the disease progresses, it may progressively worsen, and systemic symptoms such as chills and fatigue may appear. Pericardial effusion can occur when the heart is involved.

and heart failure.

Myxedema coma may occur in severe cases.

Hypothyroidism progresses slowly, and in the early stages, there may be only laboratory tests for thyroid dysfunction without symptoms, or symptoms such as chills, fatigue, slowed heart rate, and loss of appetite.

The main symptoms are decreased metabolic rate and sympathetic excitability, and most patients with mild symptoms have no specific symptoms.

Depending on the severity of the condition, symptoms can vary in severity:

chills, fatigue;

sluggish expression, unresponsiveness, depressed mood, memory loss;

hoarseness, hearing impairment, thick lips and large tongue;

Less sweating, dryness, roughness, peeling, yellowing of the soles of the hands and feet, low temperature, thinning hair;

joint pain, swelling of the hands and feet, facial and/or eyelid edema;

Slow heartbeat, constipation.

Female menstrual disorders or heavy menstrual bleeding, infertility, weight gain, etc.;

Pericardial effusion and heart failure may occur if the heart is involved.

Hello, the onset of hypothyroidism is due to certain congenital factors, mainly the patient's thyroid congenital dysplasia, the synthesis of the thyroid gland is impaired, and the patient's thyroid hormone receptor, when the hormone is reduced, hypothyroidism will occur. There are also certain factors in the day after tomorrow, mainly the patient's long-term iodine deficiency, which makes the patient's thyroid hormone synthesis raw material insufficient. Patients with overwork and kidney damage are prone to hypothyroidism.

Hypothyroidism is more afraid of cold, it is very important for our patients to take care of their body at ordinary times, we should not eat too cold food in our diet, we must not eat spicy and cold food, we must pay attention to the intake of sufficient high-calorie and high-protein and vitamin foods in our daily diet, which is also helpful to our patients' bodies. We also need to be careful not to overeat.

Dr. Ma from the Thyroid Diagnosis and Treatment Center of Chongqing National Defense Hospital introduced suggestions:

Hypothyroidism**:

1) Thyroid dysplasia:

It is common in thyroid deficiency or hypoplasia of the thyroid gland, ectopic thyroid, etc. There are many family tendencies.

2) Thyroid lesions:

Due to thyroid lesions, the secretion of thyroid hormones is insufficient, mainly including:

Thyroiditis. With chronic lymphocytic thyroiditis as the main cause, the production of thyroid antibodies, causing the destruction of thyroid follicles, and finally the atrophy of the organization, is called idiopathic hypothyroidism.

Endemic goiter. Thyroid hormone synthesis disorder due to iodine deficiency can eventually lead to hypothyroidism.

Sarcoidosis. About 10% of the thyroid gland is involved, and it can also cause insufficient synthesis and secretion of thyroid hormones, resulting in hypothyroidism.

Spontaneous hypothyroidism in hyperthyroidism. May be due to concomitant autoimmune thyroiditis.

3) Hypothalamic lesions.

Hypothalamic dysfunction is caused by some cause, which leads to a decrease in thyroid-releasing hormone, and finally a decrease in thyroid-stimulating hormone and thyroid hormone.

4) Anterior pituitary hypofunction.

Due to some reasons such as postpartum pituitary necrosis and atrophy, tumor compression, surgical or radiation injury, various infections and intracranial vascular lesions, etc., the anterior pituitary hypofunction is caused, resulting in a decrease in thyroid-stimulating hormone and thyroid hormone secretion. It is clinically common in Sheehan's disease and Simon's disease.

5) Others:

If the thyroid gland is removed too much, the thyroid gland shrinks after radioactive iodine**, and the excessive amount of antithyroid drugs such as thiourea** inhibits peroxidase, hindering thyroid hormone synthesis.

Appropriate foods for hypothyroidism:

Because the repair of the body of hypothyroidists requires the participation and action of proteins. Therefore, patients with hypothyroidism should pay attention to the use of high-protein foods.

Because the amount of iodine in the body is insufficient, it will make it difficult to synthesize thyroid-stimulating hormone, so it will lead to its deficiency, so it will cause disease. People with hypothyroidism may be able to consume some seafood, such as kelp, which is rich in iodine. Especially for hypothyroidism caused by iodine deficiency, it is necessary to choose an appropriate amount of kelp, seaweed, iodized salt, and iodine soy sauce.

Because the plasma circulation in the patient's body is not smooth, cholesterol increases, which is extremely harmful to the body's recovery. Therefore, patients with hypothyroidism should pay attention to controlling fat intake and reducing fat intake to reduce plasma cholesterol concentration.

Patients with hypothyroidism can eat some fresh fruits and vegetables to achieve the purpose of fat reduction, such as grapes, apples, etc.

Hypothyroidism**.

1. Primary hypothyroidism.

Caused by thyroid disease itself, serum TSH is elevated in patients. Mainly seen in:

congenital thyroid absence;

thyroid atrophy;

diffuse lymphocytic thyroiditis;

subacute thyroiditis;

After thyroid destruction** (radioactive iodine, surgery), radioactive iodine-131 nuclide** hyperthyroidism is the only *** is hypothyroidism and hypothyroidism (mainly referring to permanent hypothyroidism and hypothyroidism).

disorders of thyroid hormone synthesis (congenital enzyme defects, iodine deficiency or iodine excess);

drug suppression; Invasive lesions (lymphoid carcinoma, amyloidosis, etc.).

2. Secondary hypothyroidism Patients with low serum TSH. Mainly seen in pituitary disease, pituitary tumor, isolated TSH deficiency; Causes such as hypothalamic syndrome, hypothalamic tumor, isolated TRH deficiency, inflammation, or postpartum pituitary avascular necrosis.

3. Peripheral hypothyroidism.

Rare, it is a family hereditary disease, and the function of peripheral target tissues to take up hormones is good, but the receptors in the nucleus are dysfunctional or lacking, so the physiological effect on thyroid hormones is weakened.

4. Thyroid-stimulating hormone or thyroid hormone insensitivity syndrome.

It is a type of hypothyroidism caused by the thyroid gland being resistant to TSH.

First, the factor that directly leads to the disease of hypothyroidism is iodine deficiency, which is the result of changes in body functions, we can take some drugs and iodized foods or seasonings to change the body structure.

In fact, there are many foods in our lives, such as iodized salt, which can well supplement the iodine in our body, which is why iodized salt will continue to rise. Of course, this is also related to our living conditions, some families in remote areas lack sufficient nutrition, can not achieve nutritional balance, it is easy to cause symptoms of thyroid dysfunction, in fact, it is the imbalance of our body functions, which in turn leads to the occurrence of diseases.

2. The factor that indirectly causes the disease of hypothyroidism is the lifestyle of many people nowadays, such as staying up late for a long time, overwork, emotional ups and downs, etc., resulting in physical imbalance, which in turn leads to thyroid dysfunction.

Nowadays, many young people have begun to suffer from hypothyroidism, in fact, it is related to the life and rest of our young people, many people like to stay up late for a long time, and some people will continue to work overtime and work for many years, which will actually cause the body to continue to deteriorate. This condition will lead to the blockage of the liver and qi and blood in the body, and then thyroid dysfunction, many people will ignore this problem when they are young, but as they consume their body over the years, eventually the disease will continue to appear.

3. Taking too much medication can also easily lead to hypothyroidism, which is also related to one's own immunity, of course, including some hereditary conditions, and there are many reasons for complications, which should be decided according to each person's **.

Everyone's physical factors and growth environment are different, so the ** will be strange, some may be caused by one factor, and some may be caused by a variety of factors. When we use too much hyperthyroid medication in our daily lives, it can also damage the body's immune system and cause thyroid damage. Of course, heredity is also a factor that cannot be ignored, and some people are born with this disease, but it is gradually manifested in the acquired living environment.

First, thyroiditis. Second, endemic goiter. Third, sarcoidosis. Fourth, spontaneous hypothyroidism in hyperthyroidism. Fifth, hypothalamic lesions, sixth, anterior pituitary hypofunction.

There are many causes of hypothyroidism, but the most common clinical hypothyroidism, more than 99% of hypothyroidism, is caused by Hashimoto's thyroiditis. Hashimoto's thyroiditis is an autoimmune disease caused by a disorder of the autoimmune system that mistakenly attacks one's thyroid gland. Under long-term attack, thyroid cells are destroyed in large quantities, and before they have time to repair, there will be a decrease in production capacity, resulting in hypothyroidism.

The main factors that induce hypothyroidism are as follows. Congenital factors. If the patient is born with problems such as hypoplasia or dysplasia of the thyroid gland, it can also induce hypothyroidism.

Or congenital defects caused by the deficiency of some enzymes in the synthesis of thyroid hormones, which will lead to the obstruction of thyroid hormone synthesis, resulting in the production of hypothyroidism. Secondly, the defect of the thyroid hormone receptor in the tissue caused by congenital causes will also make the thyroid hormone unable to function normally, resulting in this phenomenon.

The main ** of hypothyroidism are: (1).thyroid destruction; (2).

Iodine overload; (3).antithyroid drugs; (4).Autoimmune damage, etc.

If you have hypothyroidism, you should strengthen your nutrition, eat vegetables and fruits to supplement vitamins, and ensure adequate sleep.

All factors that can cause a decrease in the synthesis or secretion of thyroid hormones; or factors that inhibit the conversion of thyroid hormones to biologically active thyroid hormones; or thyroid or nonthyroid factors that cause thyroid hormone resistance, can cause hypothyroidism.

It is recommended that patients go to the hospital in time to find out the situation, and if the problem is found, it will be carried out in time**.
