Excessive energy, unexplained weight loss - initial symptoms of hyperthyroidism can be pleasant. Therefore, they usually do not cause concern initially, but rather provide satisfaction instead of health concerns. However, this is merely the apex of the iceberg, beneath which a series of disorders lie, which will soon manifest. Although there is no specific diet recommended for hyperthyroidism, certain nutrients will have a special value. A diet can influence both the production of thyroid hormones and its function, which can help reduce the severity of the disease.
How does the thyroid gland work?
The thyroid gland is one of the hormone-secreting glands located within the body. It is responsible for regulating the function of most tissues that affect the body's metabolism, thermogenesis (heat production), and calcium-phosphorus economy. The thyroid's function is monitored by the pituitary gland, which releases the thyroid-stimulating hormone (TSH), thereby stimulating the thyroid to produce T3 and T4 hormones. The synthesis of these hormones also requires the intake of iodine and amino acids through food. The function of the thyroid and pituitary glands are interdependent, a phenomenon known as feedback regulation. This mechanism operates on the principle of effective information exchange: an elevated level of thyroid hormones leads to a decrease in the signal from the brain (release of TSH by the pituitary gland), while a deficiency of these hormones results in an increase in TSH production, which in turn encourages the thyroid to produce more T3 and T4.
