Euthyroid sick syndrome ( ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [ 1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control, dyshomeostatic disorders ...
Myxedema coma is an extreme or decompensated form of hypothyroidism and while uncommon, is potentially lethal.

Wilson's ( temperature) syndrome, also called Wilson's thyroid syndrome or WTS, is a term used in alternative medicine to improperly attribute various common and non-specific symptoms to abnormally low body temperature and impaired conversion of thyroxine (T4) to triiodothyronine (T3), despite normal thyroid function tests.

The thyroid system of the thyroid hormones T 3 and T 4 [1] Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine (T 3) and thyroxine (T 4). They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2]
