  2. Hyperthyroidism - Wikipedia

    en.wikipedia.org/wiki/Hyperthyroidism

    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.

  3. Hyperthyroxinemia - Wikipedia

    en.wikipedia.org/wiki/Hyperthyroxinemia

    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 abnormality in the channel is thought to lead to shifts of potassium into cells, under conditions of high thyroxine (thyroid hormone) levels, usually with an additional precipitant. Treatment of the low levels of potassium in the blood, followed by correction of the hyperthyroidism, leads to complete resolution of the attacks.

    Normal thyroid levels are also seen, and occasionally also hypothyroidism, which may assist in causing goiter (though it is not the cause of the Graves' disease).

    Elevated anti-thryoglobulin (TgAb) and anti-thyroid peroxidase antibodies (TPOAb) can be found in patients with Hashimoto's thyroiditis, the most common autoimmune type of hypothyroidism. TPOAb levels have also been found to be elevated in patients who present with subclinical hypothyroidism (where TSH is elevated, but free T4 is normal), and ...

  9. Thyrotoxic myopathy - Wikipedia

    en.wikipedia.org/wiki/Thyrotoxic_myopathy

    The onset of TM requires toxic levels of the thyroxine hormone due to overproduction by the thyroid gland.
