Hyperpituitarism is a condition due to the primary hypersecretion of pituitary hormones; [3] [medical citation needed] it typically results from a pituitary adenoma.In children with hyperpituitarism, disruption of growth regulation is rare, either because of hormone hypersecretion or because of manifestations caused by local compression of the 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).
Hypophysitis, inflammation of the pituitary gland.; Autoimmune hypophysitis (or lymphocytic hypophysitis), inflammation of the pituitary gland due to autoimmunity.; Nelson's syndrome, may occur after surgical removal of both adrenal glands, an out-dated method of treating Cushing's disease.
Pre-eclampsia is a multi-system disorder specific to pregnancy, characterized by the new onset of high blood pressure and often a significant amount of protein in the urine or by the new onset of high blood pressure along with significant end-organ damage, with or without the proteinuria.
Hyperpituitarism, the increased (hyper) secretion of one or more of the hormones normally produced by the pituitary gland; Hypopituitarism, the decreased (hypo) secretion of one or more of the hormones normally produced by the pituitary gland; Panhypopituitarism a decreased secretion of most of the pituitary hormones; Pituitary tumours
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). [1]
Amongst reported associations are surgery (especially coronary artery bypass graft, where there are significant fluctuations in the blood pressure), disturbances in blood coagulation or medication that inhibits coagulation, radiation therapy to the pituitary, traumatic brain injury, pregnancy (during which the pituitary enlarges) and treatment ...
Medical therapy is the preferred treatment in prolactinomas. [3] In most cases, medications that are dopamine agonists, such as cabergoline, [52] quinagolide and bromocriptine (often preferred when pregnancy is possible), are the treatment of choice used to decrease prolactin levels and tumor size upon the presence of microadenomas or ...
