Hypopituitarism

Hypopituitarism is the decreased (hypo) secretion of one or more of the eight <a href="/facts/Hormone/WFnBnINJ">hormones</a> normally produced by the <a href="/facts/Pituitary_gland/gdrQyldF">pituitary gland</a> at the base of the <a href="/facts/Human_brain/qfSwSB8K">brain</a>. If there is decreased secretion of one specific pituitary hormone, the condition is known as selective hypopituitarism. If there is decreased secretion of most or all pituitary hormones, the term panhypopituitarism (pan meaning "all") is used.
The signs and symptoms of hypopituitarism vary, depending on which hormones are under-secreted and on the underlying cause of the abnormality. The diagnosis of hypopituitarism is made by <a href="/facts/Blood_test/zevsf3rC">blood tests</a>, but often <a href="/facts/Medical_imaging/pL6JyJEp">specific scans</a> and other investigations are needed to find the underlying cause, such as <a href="/facts/Tumor/K0ytzmPz">tumors</a> of the pituitary, and the ideal treatment. Most hormones controlled by the secretions of the pituitary can be replaced by tablets or injections. Hypopituitarism is a <a href="/facts/Rare_disease/Nu1G7rEw">rare disease</a>, but may be significantly under-diagnosed in people with previous <a href="/facts/Traumatic_brain_injury/DTq110vw">traumatic brain injury</a>. The first description of the condition was made in 1914 by the German physician Dr <a href="/facts/Morris_Simmonds/851z1oAn">Morris Simmonds</a>.
