Hypothyroidism is more common in women than in men. [3] People over the age of 60 are more commonly affected. [3] Dogs are also known to develop hypothyroidism, as are cats and horses, albeit more rarely. [13] The word hypothyroidism is from Greek hypo-'reduced', thyreos 'shield', and eidos 'form', where the two latter parts refer to the ...
The hypothalamic–pituitary–thyroid axis (HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress.

Thyroid disease is a medical condition that affects the function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.
The hypothalamic-pituitary-thyroid axis. TRH can be seen in green. TRH is synthesized within parvocellular neurons of the paraventricular nucleus of the hypothalamus. [2] It is translated as a 242-amino acid precursor polypeptide that contains 6 copies of the sequence -Gln-His-Pro-Gly-, with both ends of the sequence flanked by Lys-Arg or Arg-Arg sequences.
The diagnosis of hypothyroidism, when suspected, can be confirmed with blood tests measuring thyroid-stimulating hormone (TSH) and thyroxine levels. [1] People over the age of 60 are more commonly affected.
TRH-stimulation testing however continues to be useful for the differential diagnosis of secondary (pituitary disorder) and tertiary (hypothalamic disorder) hypothyroidism. Patients with these conditions appear to have physiologically inactive TSH in their circulation that is recognized by TSH assays to a degree such that they may yield ...
Pickardt's syndrome may cause difficulties in differential diagnosis of pituitary adenomas, as both suprasellar hormone-inactive adenomas and prolactinomas may be associated with increased prolactin levels, central hypogonadism and central hypothyroidism. Usually, the prolactin levels are higher in case of a true prolactinoma, but the ...
