hypopituitism
Hypopituitarism, commonly spelled hypopituitarism but sometimes referred to as hypopituitism, is a disorder in which the pituitary gland fails to secrete adequate amounts of one or more pituitary hormones. It may affect a single hormonal axis (partial hypopituitarism) or several axes (panhypopituitarism). Because the pituitary regulates other endocrine glands, the resulting hormone deficiencies are described as central or secondary hypopituitarism. Involvement of the posterior pituitary can cause diabetes insipidus, a separate axis of dysfunction.
Common causes include pituitary adenomas and their treatment (surgery or radiotherapy), postpartum pituitary infarction (Sheehan syndrome),
Deficiencies of anterior pituitary hormones produce a range of symptoms. ACTH deficiency leads to secondary adrenal
Diagnosis relies on clinical suspicion, hormonal testing showing multiple low pituitary axes, and MRI to identify
