What are the symptoms of high thyroid line?

The thyroid gland is like a factory that can produce thyroid hormones. If the thyroid hormones produced are too high, it can easily lead to hyperthyroidism, that is, hyperthyroidism. This will cause a series of changes in the body, which is quite harmful to the health of the body. It often causes patients to drink and eat more, become emaciated, have mood swings, etc. When the thyroid hormones are high, you must go to the hospital for examination in time.

What are the symptoms of high thyroid line?

Generally speaking, the main reason for high thyroid hormone is that the human body absorbs excessive iodine. Iodine can promote the secretion of thyroid hormone and aggravate the condition of patients with hyperthyroidism. All edible salt on the market is iodized salt. For people in some coastal areas, sometimes the body absorbs excessive iodine.

In hyperthyroidism, excessive secretion of thyroid hormones promotes the metabolism of nutrients such as fat and protein and accelerates oxidation. The body's heat production and heat dissipation increase significantly, and the basal metabolic rate increases abnormally, so energy must be increased every day to correct the body's energy consumption. Based on the above reasons, the diet of patients with hyperthyroidism must pay attention to high calories, high protein, high vitamins and supplements of calcium, phosphorus, potassium, zinc, magnesium, etc., in order to correct the consumption caused by hypermetabolism and improve the overall condition.

Effects of thyroid hormones

1. Promote growth and development

The growth-promoting effects of thyroid hormones are most evident during infancy, with the greatest impact occurring within the first four months of life. It mainly promotes the growth and development of bones, brain and reproductive organs. Without thyroid hormone, the pituitary GH cannot function. Moreover, when thyroid hormone is deficient, the pituitary gland's production and secretion of GH also decreases. Therefore, congenital or childhood lack of thyroid hormone causes cretinism. Cretinism patients have stagnant bone growth and are short in stature. The length ratio of the upper and lower body is abnormal, with the upper body accounting for a larger proportion than that of normal people. Due to the growth disorders of nerve cell dendrites, axons, myelin sheath and glial cells, the brain is not fully developed and mental retardation occurs. Their sexual organs also fail to mature. Patients must supplement thyroid hormone about three months after birth. After this period, treatment is often ineffective.

2. Impact on metabolism

Thermogenic Effect Thyroid hormones increase the rate of oxygen consumption in most tissues, increasing thermogenesis. This thermogenic effect may be due to the fact that thyroid hormones can increase the synthesis of Na+-K+ pumps on cell membranes and increase their activity, the latter of which is an energy-consuming process. Thyroxine increases the basal metabolic rate. 1 mg of thyroxine can increase heat production by 4000KJ. The basal metabolic rate of patients with hyperthyroidism can increase by about 35%, while the basal metabolic rate of patients with hypothyroidism can decrease by about 15%.

Its effects on the metabolism of the three major nutrients are very complex. In general, under normal circumstances, thyroid hormones mainly promote protein synthesis, especially significantly increasing protein synthesis in bones, skeletal muscles, liver, etc., which is of great significance for growth and development in childhood. However, excessive secretion of thyroid hormones will cause a large amount of protein breakdown, especially skeletal muscle protein, resulting in weight loss and weakness. In terms of sugar metabolism, thyroid hormones promote sugar absorption and the decomposition of liver glycogen. At the same time, it can also promote the utilization of sugar by peripheral tissues. In short, it accelerates the metabolism of sugar and fat, especially promotes the decomposition and oxidation process of sugar, fat and protein in many tissues, thereby increasing the body's oxygen consumption and heat production.

3. Other aspects

In addition, thyroid hormones also play an important role in the activities of some organs. It plays an important role in maintaining the excitability of the nervous system. Thyroid hormones can directly act on the myocardium, promote the release of Ca2+ from the sarcoplasmic reticulum, enhance myocardial contractility, and increase heart rate.
