What is the initial symptom of hyperthyroidism?

summary

Hyperthyroidism, in medical terms, refers to "thyrotoxicosis": it is a clinical symptom caused by excessive thyroid hormone, while hyperthyroidism is limited to thyroid. It is thyrotoxicosis caused by excessive hormone synthesis and secretion. Hyperthyroidism is an organ immune disease, the most common invasion is thyroid, eyes, rare anterior tibial mucinous edema and so on. What is the initial symptom of hyperthyroidism? Let's talk about it

What is the initial symptom of hyperthyroidism?

Water and salt metabolism and vitamin metabolism disorder: thyroid hormone can promote diuresis, excretion of potassium and magnesium, so hyperthyroidism is prone to hypokalemic periodic paralysis and hypomagnesemia. The transport of calcium and phosphorus is accelerated, and there are often high urine calcium, high urine phosphorus and high urine magnesium; For a long time, bone decalcification and osteoporosis can occur. When hypocalcemia occurs, the patients take insufficient calcium. A few patients may have secondary hyperparathyroidism. At the same time, due to the poor absorption, fast metabolism and high consumption of hyperthyroidism, vitamin B1, C, D and other vitamin deficiency and trace element deficiency can occur.

Symptoms of abnormal metabolism of skin and muscle: negative balance of protein metabolism, negative balance of creatine, negative balance of nitrogen, decrease of ATP and creatine phosphate, prone to hyperthyroid myopathy, ocular muscle weakness, myasthenia gravis, or frequent soft paralysis. Myxedema occurred in the skin, mostly in the eyelids and tibia. Nail softening or deformation and infection.

Cardiovascular system symptoms: thyroid hormone excites cardiac sympathetic nerve, enhances catecholamine effect, appears tachycardia, arrhythmia, heart sound enhancement, pulse pressure increase, even heart enlargement, apical systolic murmur. The elderly are prone to atrial fibrillation, angina pectoris and even hyperthyroid heart disease and coronary heart disease at the same time, resulting in heart failure.

matters needing attention

① In order to prevent iodine hyperthyroidism, the coastal areas should pay attention to the food containing iodine; ② In inland areas (iodine deficiency areas), the date of iodine supplement should be limited, and the time limit for taking thyroid tablets should also be limited; ③ In general health survey, thyroid B-ultrasound or thyroid function should be added to detect patients with hyperthyroidism in the early stage. When patients with hyperthyroidism are found passively, their condition is often delayed for 2-3 years.
