Pituitary disorders can cause a wide spectrum of symptoms, both hormonal and neurological, due to its location near the brain, the intracranial nerves and blood vessels and because of the vital hormonal control that the gland provides. Diagnosis of pituitary disease...
Is Pituitary Tumor Surgery Risky?
Surgery is a common treatment, and it is almost always successful IF performed by a skilled and specialized neurosurgeon. The smaller the tumor, the greater the chance the surgery will be successful. Large tumors that grow upward (into the nerves that mediate vision)...
Which Hormones Are Produced And/Or Controlled By The Posterior Pituitary Or Hypothalamus?
Oxytocin stimulates contractions of the uterus during labor and the ejection of milk during breast-feeding. Antidiuretic Hormone (ADH) increases reabsorption of water into the blood by the kidneys and therefore decreases urine production. Also referred to as...
How Do I Get Diagnosed?
Anyone suffering from a constellation of complaints/clinical findings suspicious for pituitary disease should get blood and urinary hormone levels checked and, if indicated, a brain MRI, keeping in mind that microadenomas may not show up on the x-rays. Combinations of...

What Causes The Pituitary To Malfunction?
Tumors (overwhelmingly benign), inflammation, infections and injury can cause the gland to malfunction, as well as metastasis or spread of other tumors to the pituitary (rare). Radiation therapy to the brain can also cause normal pituitary cells to malfunction.
What Happens If The Pituitary Produces Either Too Much Or Too Little Of These Hormones?
An imbalance occurs, leading to more than a dozen disorders of the endocrine system. Deficiency of thyroid hormone, adrenal cortical hormone (cortisol) or antidiuretic hormone (vasopressin) is rapidly life-threatening. In patients with abnormalities of the other...
