The diagnosis of hyperthyroidism is confirmed by blood tests that show a decreased thyroid-stimulating hormone (TSH) level and elevated T 4 and T 3 levels. TSH is a hormone made by the pituitary gland in the brain that tells the thyroid gland how much hormone to make. When there is too much thyroid hormone, the TSH will be low.
Hyperthyroxinemia is a thyroid disease where the serum levels of thyroxine are higher than expected. [1] Thyroxine or tetraiodothyronine (T4) is produced by the thyroid gland. The term is sometimes used to refer to hyperthyroidism, but hyperthyroidism is a more general term. [2]
The most useful marker of thyroid gland function is serum thyroid-stimulating hormone (TSH) levels. TSH levels are determined by a classic negative feedback system in which high levels of T3 and T4 suppress the production of TSH, and low levels of T3 and T4 increase the production of TSH. TSH levels are thus often used by doctors as a screening ...

[22] [23] 3,5-T2 levels were also observed to correlate with concentrations of rT3 (reverse T3) [22] in patients with euthyroid sick syndrome. NTIS is a component of a complex endocrine adaptation process, so affected patients might also have hyperprolactinemia and elevated levels of corticosteroids (especially cortisol) and growth hormone.
Thyroid disease also has a marked effect on BMR, since thyroid hormones regulate the rate of cellular metabolism. [3] Hyperthyroidism—in which there is an increase in the production of thyroid hormones—leads to a high BMR, while hypothyroidism—in which thyroid hormones are depleted—causes a low BMR. [1]
