  2. Empty sella syndrome - Wikipedia

    en.wikipedia.org/wiki/Empty_sella_syndrome

    Secondary empty sella syndrome is the result of the pituitary gland regressing within the cavity after an injury, surgery, or radiation therapy. [3] Individuals with secondary empty sella syndrome due to destruction of the pituitary gland have symptoms that reflect the loss of pituitary functions, such as intolerance to stress and infection.

  3. Autoimmune hypophysitis - Wikipedia

    en.wikipedia.org/wiki/Autoimmune_hypophysitis

    Autoimmune hypophysitis can lead to deficiencies in one or more pituitary hormones, causing central diabetes insipidus if the posterior pituitary gland is affected as well as central adrenal insufficiency and central hypothyroidism if the anterior pituitary gland is affected. [1] The symptoms depend on what part of the pituitary is affected.

  4. Sheehan's syndrome - Wikipedia

    en.wikipedia.org/wiki/Sheehan's_syndrome

    Other hormone-secreting cells of the pituitary undergo rapid growth in pregnant women as well, which contribute to the gland's enlargement. [10] The anterior pituitary is supplied by a low pressure portal venous system. [15] The anterior pituitary is more commonly affected in Sheehan's syndrome because of the structure of the portal venous system.

  5. Nelson's syndrome - Wikipedia

    en.wikipedia.org/wiki/Nelson's_syndrome

    Nelson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat Cushing's disease. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...

    en.wikipedia.org/wiki/Hypergonadotropic_hypogonadism

    Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production. [1]

  7. Hypophysitis - Wikipedia

    en.wikipedia.org/wiki/Hypophysitis

    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.

  8. Hypoprolactinemia - Wikipedia

    en.wikipedia.org/wiki/Hypoprolactinemia

    Hypoprolactinemia can result from autoimmune disease, [2] hypopituitarism, [1] growth hormone deficiency, [2] hypothyroidism, [2] excessive dopamine action in the tuberoinfundibular pathway and/or the anterior pituitary, and ingestion of drugs that activate the D 2 receptor, such as direct D 2 receptor agonists like bromocriptine and pergolide, and indirect D 2 receptor activators like ...

  9. Hypopituitarism - Wikipedia

    en.wikipedia.org/wiki/Hypopituitarism

    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]
