    GH deficiency may contribute to decreased energy but is usually asymptomatic and clinically undetectable in adults. Suggestions that GH deficiency accelerates atherosclerosis are unproved. [merckmanuals.com]

  • Falling

    Head trauma from a motor vehicle accident, a fall, or a projectile can cause hypopituitarism by direct damage to the pituitary or by injuring the pituitary stalk or the hypothalamus. [emedicine.medscape.com]

    Studies show seniors who take sleeping pills have twice the rate of falling of those who don’t. When Medicare launched its drug plan in 2006, benzodiazepines were not covered, although the program overturned that decision starting in 2013. [bendbulletin.com]

    If the urine then becomes concentrated and the blood osmolarity falls, there is a lack of ADH due to lack of pituitary function ("cranial diabetes insipidus"). [en.wikipedia.org]

  • Inflammation

    Headaches may also accompany pituitary tumors, [1] as well as pituitary apoplexy (infarction or haemorrhage of a pituitary tumor) and lymphocytic hypophysitis ( autoimmune inflammation of the pituitary). [8] Apoplexy, in addition to sudden headaches and [en.wikipedia.org]

Treatment of hypopituitarism consists of hormone replacement therapy and treatment of the underlying disorder (e.g., transsphenoidal resection of pituitary adenomas ). [amboss.com]

The type of glucocorticoid, dose and duration of treatment are factors to consider when trying to predict the risk of developing symptoms of AI. [karger.com]

It requires lifelong treatment with one or more medicines. [en.wikipedia.org]

Prognosis Although an increased mortality rate in hypopituitary patients is well documented, the actual cause of the increased mortality is not clear. [ 9 ] If adequately replaced, prognosis in hypopituitarism is good. [patient.info]

While effective treatment of the underlying hormone deficiencies may improve these risks, it is often necessary to treat them directly. [6] Prognosis [ edit ] Several studies have shown that hypopituitarism is associated with an increased risk of cardiovascular [en.wikipedia.org]

They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]

Etiology Intrasellar/parasellar masses Nonsecretory pituitary macroadenomas ( 10 mm in diameter) are the most common cause of hypopituitarism among adults ( 40% of cases ). [amboss.com]

Therefore, we proposed a classification of SEH, according to the most probable etiology whatever the associated factors, in six groups: spontaneous, secondary, iatrogenic, traumatic, recurrent, and idiopathic SEH. [publicationslist.org]

Lymphocytic Hypophysitis • Etiology Presumed to be autoimmune • Clinical Presentation Women, during postpartum period Mass effect (sellar mass) Deficiency of one or more anterior pituitary hormones  ACTH deficiency is the most common • Diagnosis [slideshare.net]

Hypopituitarism is usually chronic and lifelong, unless successful surgery or medical treatment of the underlying disorder can restore pituitary function. [ 1 ] Epidemiology Taken from the results of one study: [ 1 ] The incidence of hypopituitarism is [patient.info]

However, sports are not generally considered as a cause of TBI in most epidemiological studies, and the link between sports-related head trauma and hypopituitarism has not been investigated until recently. [publicationslist.org]

Epidemiology [ edit ] There is only one study that has measured the prevalence (total number of cases in a population) and incidence (annual number of new cases) of hypopituitarism. [1] This study was conducted in Northern Spain and used hospital records [en.wikipedia.org]

Understanding the pathophysiological mechanisms and risk factors of hypopituitarism caused by sports injuries is thus an important issue that concerns both medical staff and sponsors of sports. [publicationslist.org]

Pathophysiology [ edit ] The pituitary gland is located at the base of the brain, and intimately connected with the hypothalamus. [en.wikipedia.org]

Prevention Good obstetric care has reduced the incidence of postpartum hypopituitarism. Radiation therapy that minimises exposure to the pituitary reduces incidence and time of onset of hypopituitarism. [patient.info]
