  2. 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.

  3. Multiple endocrine neoplasia type 1 - Wikipedia

    en.wikipedia.org/wiki/Multiple_endocrine...

    If the tumors become cancerous, some cases can be life-threatening. The disorder affects 1 in 30,000 people. Although many different types of hormone-producing tumors are associated with multiple endocrine neoplasia, tumors of the parathyroid gland, pituitary gland, and pancreas are most frequent in multiple endocrine neoplasia type 1.

  4. Endocrine disease - Wikipedia

    en.wikipedia.org/wiki/Endocrine_disease

    Endocrine disorders are often quite complex, involving a mixed picture of hyposecretion and hypersecretion because of the feedback mechanisms involved in the endocrine system. For example, most forms of hyperthyroidism are associated with an excess of thyroid hormone and a low level of thyroid stimulating hormone. [2]

  5. 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.

  6. Pituitary adenoma - Wikipedia

    en.wikipedia.org/wiki/Pituitary_adenoma

    Hormone secreting pituitary adenomas cause one of several forms of hyperpituitarism. The specifics depend on the type of hormone. Some tumors secrete more than one hormone, the most common combination [8] being GH and prolactin, which present as Gigantism or Acromegaly and unexpected lactation (in both men and women). [citation needed]

  7. Prolactinoma - Wikipedia

    en.wikipedia.org/wiki/Prolactinoma

    A prolactinoma is a tumor of the pituitary gland that produces the hormone prolactin.It is the most common type of functioning pituitary tumor. [1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood (hyperprolactinemia), or due to pressure of the tumor on surrounding brain tissue and/or the optic nerves.

  8. Macroorchidism - Wikipedia

    en.wikipedia.org/wiki/Macroorchidism

    Surgical removal of the tumor is the most important and advised option for treating macroorchidism caused by non-functioning pituitary macroadenoma. [12] A non-functioning pituitary adenoma is a kind of benign tumor that does not secrete active hormones, and is from the pituitary gland. [13]

  9. Syndrome of inappropriate antidiuretic hormone secretion

    en.wikipedia.org/wiki/Syndrome_of_inappropriate...

    Central nervous system (CNS) disorders or conditions may cause SIADH in 9% of cases, this includes subarachnoid hemorrhage (56% of CNS causes), pituitary surgery (35% of CNS causes), brain cancer, infections, stroke and head trauma. [2] No cause of inappropriate antidiuresis is initially found in 17–60% of cases. [2]
