Respuesta :
The correct answer is There could be two different scenarios. First, despite receiving adequate hormonal input from the hypothalamus and anterior pituitary, the thyroid gland may create too much thyroid hormone.
Second, abnormally high thyroid-stimulating hormone (TSH) levels may be the cause of an overactive thyroid gland. Therefore, there is a possibility that both diagnoses are accurate.
Numerous glands in the body produce hormones, which have a variety of physiological effects. Growth and development depend on hormones.
The thyroid gland creates the thyroid hormones triiodothyronine (T3) and thyroxine (T4). The rate at which calories are eaten by each and every cell and organ in the body is regulated by thyroid hormones, which also control weight gain and loss.
When activated by TSH, the thyroid gland produces thyroid hormones. Blood tests that measure T3, T4, and TSH levels can be used to identify several medical conditions.
When the thyroid gland generates too much thyroxine, hyperthyroidism (overactive thyroid) results. In addition to causing weight loss, hyperthyroidism accelerates the body's metabolism, which results in a rapid or erratic heartbeat.
Iodine toxicity may result in the thyroid producing an excessive amount of thyroid hormones.
