Introduction
Hyperthyroidism refers to hyperfunction of the thyroid gland. Increasing intolerance to heat is caused by a hypermetabolic syndrome. Thyroid hormones are excitatory hormones that maintain normal metabolism in the human body. In hyperthyroidism, overactive thyroid function leads to excessive secretion and release of thyroid hormones into the bloodstream, resulting in a series of symptoms dominated by hypermetabolism, thereby causing progressively worsening heat intolerance.
Hyperthyroidism generally refers to an overactive thyroid gland. Increasing sensitivity to heat is primarily caused by the hypermetabolic syndrome.
Under normal circumstances, thyroid hormones are excitatory hormones that maintain the body's normal metabolism. When a person has hyperthyroidism, the thyroid gland becomes excessively active, leading to excessive production and release of thyroid hormones into the bloodstream. This results in a series of symptoms dominated by high metabolism, causing increased heat intolerance, palpitations, rapid heartbeat, excessive sweating, thirst, and other discomforts.
After developing a range of symptoms due to hyperthyroidism, it is recommended to seek timely medical treatment at a hospital. Under a doctor's guidance, antithyroid medications such as methylthiouracil or propylthiouracil can be used to help suppress thyroid hormone synthesis and control hyperthyroid symptoms. Alternatively, radioactive iodine-131 therapy may be administered as directed by a physician, which helps destroy thyroid tissue and reduce thyroid hormone production, thereby managing the symptoms caused by hyperthyroidism.
