Excessive iodine can also harm human health and can cause diseases, but it is often ignored by people. High iodine goiter, or iodine-induced goiter, is caused by the body's intake of far more than physiological requirements. Goiter caused by iodine. A series of hypermetabolic syndromes and hypermetabolic syndromes in the body's nervous system, circulatory system, digestive system, cardiovascular system and other multiple systems caused by excessive consumption of iodine or excessive secretion of thyroid hormones or increased levels of thyroid hormones (T3, T4) in the blood. Excitement symptoms and ocular symptoms. Clinically, the main symptoms of hyperthyroidism patients are: palpitation, tachycardia, heat intolerance, excessive sweating, hyperappetite, weight loss, weight loss, fatigue and irritability, irritable temper, insomnia, inability to concentrate, exophthalmos, and trembling hands and tongue. , goiter or enlargement, women may have menstrual irregularities or even amenorrhea, and men may have impotence or breast development. Goiter is symmetrical, and some patients have asymmetric enlargement. The goiter or enlargement will move up and down with swallowing, and some patients with hyperthyroidism have thyroid nodules. One type of eye changes caused by hyperthyroidism is benign exophthalmos, in which the patient's eyes protrude, stare or show fear; the other is malignant exophthalmos, which can be transformed from benign exophthalmos. Patients with malignant exophthalmos often have fear. Light, tearing, diplopia, vision loss, eye swelling and pain, stinging, foreign body sensation, etc. Due to the highly protruding eyeball, the eyes cannot be closed, and the conjunctiva and cornea are exposed, causing congestion, edema, corneal ulceration, etc., and even blindness. Some patients with hyperthyroidism have no eye symptoms or symptoms are not obvious. The above are all typical clinical manifestations of hyperthyroidism, but not every patient with hyperthyroidism has all clinical symptoms. Different types of hyperthyroidism have different clinical manifestations.

2. Among daily foods, kelp, seaweed, sea cabbage, marine fish, shrimp, crab, and shellfish are rich in iodine. Excessive iodine is detrimental to the condition and manifests as:

(1) Aggravation of hyperthyroidism: Since iodine is the main raw material for manufacturing thyroid hormone, long-term use of iodine can aggravate hyperthyroidism and even cause iodine-derived hyperthyroidism.

(2) Unfavorable to treatment: Eating too much iodine may also harden the thyroid tissue, causing the condition to linger and affecting antithyroid drug treatment. Excessive iodine will prolong the time for thyroid drug treatment of hyperthyroidism. The cure rate has dropped, and the cure rate for hyperthyroidism with antithyroid drugs has dropped to 20% to 35% after excessive iodine supplementation.

Therefore, patients with hyperthyroidism should avoid eating iodine-containing foods such as kelp, seaweed, and marine fish, and iodine-containing traditional Chinese medicines such as seaweed and kelp are prohibited. Patients should use non-iodized salt. If it is iodized salt, stir-fry the iodized salt at high temperature for a period of time before eating it to allow the iodine to evaporate.

3. Patients with hyperthyroidism should pay attention to the following during medication and diet:

(1) Spicy foods are taboo: chili peppers, raw onions, and raw garlic;

( 2) Taboo seafood: kelp, shrimp, hairtail;

(3) Taboo strong tea, coffee, tobacco and alcohol;

(4) Keep your mood calm and prevent fatigue.

Hyperthyroidism is a disease caused by the thyroid gland secreting too much thyroid hormone. This disease is more common in women. Excessive thyroid hormone can cause a series of clinical manifestations, such as heat intolerance, excessive sweating, hyperappetite, weight loss, palpitation, emotional stress, and irritable temper. Most patients with hyperthyroidism have thyroid enlargement, and the degree of enlargement ranges from mild to severe. A very small number of patients with hyperthyroidism do not have thyroid enlargement. Many patients with hyperthyroidism also have exophthalmos, which can range from mild to severe. Thyroid function tests can reveal that the 131 iodine absorption rate of the thyroid gland increases, and the levels of thyroid hormones (T3, T4) in the blood increase significantly. The most common type of hyperthyroidism is toxic diffuse goiter, accounting for about 80% of all hyperthyroidism patients. The cause is mainly related to immune dysfunction and congenital inheritance.

Where is the thyroid located in the body?

In daily conversations, many people do not know where the thyroid is located in the body. The thyroid gland is located at the front and bottom of the neck, behind the sixth tracheal cricoid cartilage, and in front of the anterior cervical muscles. The human thyroid gland begins to appear during the fetal period. After the fetus is born, the thyroid gland develops into two left and right gland lobes. The middle part connecting the two lobes is the isthmus. When the thyroid gland matures during adolescence, the weight of the thyroid gland is 15 to 30 grams, the width of the two lobes is 2 to 2.5 cm, and the height is 4 to 5 cm. The width of the isthmus is 2 cm and the height is 2 cm. Women's thyroid glands are slightly larger than men's.

Normally, because the thyroid gland is so small and thin, it cannot be seen or touched in the neck. If the thyroid gland can be felt in the neck, even if it cannot be seen, it is considered to be enlarged. Swelling of this degree is often physiological, especially during female puberty, and is generally not the result of disease, but sometimes it can be pathological.

What is hyperthyroidism crisis

If hyperthyroidism is not cured for a long time, a series of complications may occur, such as hyperthyroid heart disease, hyperthyroidism limb paralysis, hyperthyroidism hypertension, hyperthyroidism Diabetes, hyperthyroidism, mental illness, etc., can lead to hyperthyroidism crisis in severe cases, which can often be life-threatening if rescue is not urgent.

Hyperthyroid crisis is a rapid deterioration of hyperthyroidism, leading to severe systemic metabolic disorders and serious dysfunction of the cardiovascular system, digestive system, nervous system and other functions. It is often life-threatening. If diagnosis and rescue measures are not timely, the mortality rate will increase. Extremely high. Even if diagnosis and treatment are timely, about 5 to 15% of patients will not survive.

The cause of this disease is still not completely clear. Hyperthyroidism crisis often occurs when certain stress factors are encountered when hyperthyroidism has not been treated or has not been controlled through treatment. Under stress, the thyroid gland synthesizes a large amount of thyroid hormone and releases it into the blood, which sharply aggravates the original condition of hyperthyroidism. Moreover, stress can significantly increase the activity of catecholamines, further aggravating the condition.
