The signs and symptoms of hypopituitarism vary, depending on which hormones are undersecreted and on the underlying cause of the abnormality. The diagnosis of hypopituitarism is made by blood tests, but often specific scans and other investigations are needed to find the underlying cause, such as tumors of the pituitary, and the ideal treatment ...
As magnetic resonance imaging became more available diagnosis increased dramatically. [16] At this time it is believed that the disease is far more prevalent than is diagnosed. [7] Nevertheless, autoimmune hypophysitis is frequently referred to as a rare disease and the most recent estimates as to its prevalence give it a value of around 5 per ...
For example, insufficient production (hyposecretion) of thyroid stimulating hormone (TSH) in the pituitary gland will cause hypothyroidism, while overproduction (hypersecretion) of TSH will cause hyperthyroidism. Thyroidisms caused by the pituitary gland are less common though, accounting for less than 10% of all hypothyroidism cases and much ...
There are many causes of AHH, mostly due to structural lesions or functional abnormalities involving the HPG axis such as sarcoidosis, lymphocytic hypophysitis, pituitary adenomas, craniopharyngiomas and other CNS tumours. Most of these patients have multiple pituitary hormone deficiencies. [12] Hyperprolactinaemia is the
Sheehan's syndrome, also known as postpartum pituitary gland necrosis, occurs when the pituitary gland is damaged due to significant blood loss and hypovolemic shock (ischemic necrosis) or stroke, originally described during or after childbirth leading to decreased functioning of the pituitary gland (hypopituitarism).

This usually occurs in the presence of a tumor of the pituitary, although in 80% of cases this has not been diagnosed previously. The most common initial symptom is a sudden headache , often associated with a rapidly worsening visual field defect or double vision caused by compression of nerves surrounding the gland.
The prognosis for hypophysitis was variable for each individual. The depending factors for hypophysitis included the advancement of the mass on the sella turcica, percentage of fibrosis, and the body's response to corticosteroids. Through the use of corticosteroids, the vision defects tend to recover when the gland size began to decrease.
Usually the ulcers are multiple or atypical in location, and often bleed, perforate, or become obstructed. Peptic ulcer disease may be intractable and complicated. Among patients presenting with Zollinger-Ellison syndrome, 20 to 60% have MEN 1. A severe secretory diarrhea can develop and cause fluid and electrolyte depletion with non–β-cell ...
