Hypothyroidism definition and danger? A The full name of hypothyroidism is hypothyroidism, which refers to the inability of the thyroid gland to produce enough thyroid hormones to meet the normal needs of the body for various reasons. In children, hypothyroidism can significantly hinder the growth and development of infants and children, especially the skeletal system and the nervous system; in early childhood, hypothyroidism is characterized by delayed growth and mental retardation; in those who develop hypothyroidism after the age of 2, the impact on IQ is smaller; children with hypothyroidism are less active and start to teethe, walk and talk later than children of the same age; those who develop hypothyroidism in adulthood are called adult hypothyroidism, and the most serious ones can affect the respiratory center and cause sleep apnea. The most severe cases can affect the respiratory center, causing sleep apnea, even respiratory failure, and even death. In our country, hypothyroidism is a screening disease for newborns, and pregnant women should go to a larger hospital to have their babies screened for hypothyroidism. What are the causes of hypothyroidism? Hypothyroidism is caused by a lack of thyroid stimulating hormone due to brain lesions, such as pituitary tumor surgery, which destroys the pituitary gland’s center of thyroid control (command); 2. hypoplasia or underdevelopment of the thyroid gland; 3. thyroid hormone synthesis disorder, which is autosomal recessive; 4. other maternal factors; 5. hypothyroidism due to surgical removal of part of the thyroid gland; 6. 7. subacute thyroiditis, due to viral invasion, which directly destroys part of the thyroid tissue; 8. increased thyroid antibodies in patients with Hashimoto’s thyroiditis, which damages part of the thyroid tissue and causes hypothyroidism; 9. other causes, such as thyroid hormone resistance, etc. What are the symptoms of hypothyroidism? The early appearance of hypothyroidism symptoms and their severity are related to the residual thyroid secretion function of the affected child. Symptoms appear early in those with congenital thyroid deficiency or enzyme defects. The main features are growth retardation, mental retardation and low basal metabolic rate. In the neonatal period: 1, often overdue birth; 2, birth weight more than normal newborns; 3, delayed physiological jaundice >2W,; 4, abdominal distention, constipation, excessive sleepiness; 5, low voice; 6, feeding difficulties; 7, body temperature does not rise or even hard swelling. Children often present with typical symptoms six months after birth and seek medical attention. Low physiological function Low heart sounds, slow pulse, low voltage EKG, prolonged T-wave with prolonged P-R interval; slow breathing; abdominal distension, constipation, etc.; poorer mental, appetite, activity, responsiveness to surrounding things than children of the same age; low body temperature and fear of cold; low muscle tone. Special facial and physical appearance 1, short stature, long trunk and short limbs, upper volume > lower volume > 1.5, 2, pale yellow skin, rough, thickened, showing the whole body bloated; 3, large head, sparse hair, dry; 4, wide eye distance, small eye fissure; 5, wide and flat nasal bridge; 6, thick lips, large and wide tongue often sticks out of the mouth, a typical bloated face; 7, short neck; 8, abdominal bulge, often umbilical hernia, waist spine Anterior convexity. Older children with the following symptoms, if they contain 5 or more, it is recommended to go to the hospital and check the nail function easily sleepy, physical strength and energy are very low; slow thinking, concentration is difficult, memory loss; weight gain; dry skin, nails become brittle, gray, easy to break; often feel cold; easily depressed depression; easy to stool; feel muscle and bone stiffness pain, hands feel numb, numb, numb. Increased blood pressure or slowed heartbeat; increased cholesterol levels; hypothyroidism diagnosis? The diagnosis of disease requires a combination of clinical symptoms, signs and laboratory tests, and hypothyroidism is no exception. When patients experience weakness, drowsiness, memory loss, coldness, swelling and other discomforts, they need to seek medical attention and undergo laboratory tests to diagnose whether they have hypothyroidism. The indicators that need to be tested include thyroid function, thyroid autoantibodies and other specific indicators. How is hypothyroidism treated? As a general rule, hypothyroidism is treated with replacement therapy. The amount of replacement needs to be individualized according to the degree of hypothyroidism and the patient’s own condition. In mild hypothyroidism, no special treatment is usually needed, and treatment can be achieved by using dietary therapy and eating appropriate seafood to supplement iodine, the raw material for thyroid hormone production, while in moderate and severe hypothyroidism, thyroid hormone replacement therapy must be used. The specific dosage needs to vary from person to person hypothyroidism is generally irreversible and requires lifelong replacement therapy. Does hypothyroidism require lifelong medication? What are the side effects of the medication? What should I be aware of when taking the medication? A. Hypothyroidism is generally irreversible and requires lifelong replacement therapy. However, the dosage varies from person to person, and the best dosage should be given according to the patient’s needs. The most important medication is levothyroxine tablets (Eugenol), which is a synthetic thyroid hormone, the same as natural thyroid hormone, so it has no side effects on the human body. However, it should be noted that if the replacement dose is too high, it may lead to drug-induced hyperthyroidism, so the dose needs to be adjusted and individualized from person to person, and the patient needs to promptly visit or consult a professional endocrinologist to determine if the drug dose needs to be adjusted. If you take Eugenol on an empty stomach, it is well absorbed, but if you take a larger dose, you can take it in divided doses, but it is not recommended to take it at night because it is an excitatory hormone and taking it at night may lead to insomnia and other conditions.
