Hypopituitarism is the decreased (hypo) secretion of one or more of the eight hormones normally produced by the pituitary gland at the base of the brain. [ 1 ] [ 2 ] If there is decreased secretion of one specific pituitary hormone, the condition is known as selective hypopituitarism. [ 3 ]
However, clinical, laboratory data, and imaging can all help with the diagnosis.[8] First and foremost, patients present with symptoms of hypopituitarism and must undergo pituitary hormone function evaluation. [1] Biopsy is the only means of accurate diagnosis as no autoantigen has been discovered.
Idiopathic ketotic hypoglycemia; Isolated growth hormone deficiency, hypopituitarism; Insulin excess. Hyperinsulinism due to several congenital disorders of insulin secretion; Insulin injected for type 1 diabetes; Hyperinsulinism-hyperammonemia syndrome (HIHA) due to glutamate dehydrogenase 1 gene. Can cause intellectual disability and epilepsy ...
Growth hormone deficiency in childhood commonly has no identifiable cause (idiopathic), and adult-onset GHD is commonly due to pituitary tumours and their treatment or to cranial irradiation. [9] A more complete list of causes includes: mutations of specific genes (e.g., GHRHR, GH1)
If there are symptoms, people with empty sella syndrome can have headaches and vision loss. Additional symptoms would be associated with hypopituitarism. [3] [4] Additional symptoms are as follows: [citation needed] Abnormality of the middle ear ossicles; Cryptorchidism; Dolichocephaly; Arnold-Chiari type I malformation; Meningocele; Patent ...
Most commonly, the initial symptoms are headaches and visual disturbances. Some symptoms are derived from the lesser functioning of the adenohypophyseal hormones. Of the adenohypophyseal hormones, the most frequently affected are corticotropes , lactotropes and gonadotropes , all which are found in the anterior pituitary.

In a study of 1,034 symptomatic adults, Sheehan's syndrome was found to be the sixth-most frequent etiology of growth hormone deficiency, being responsible for 3.1% of cases (versus 53.9% due to a pituitary tumor). [8] Additionally, it was found that the majority of women who experienced Sheehan syndrome gave birth at home rather than in a ...
