Pituitary Disorders

A pituitary disorder is a disorder frequently affecting the pituitary gland. Excess production or underproduction of a pituitary hormone will affect the respective end-organ. For example, inadequate production (hyposecretion) of thyroid-stimulating hormone (TSH) in the pituitary gland will motive hypothyroidism, even as overproduction (hypersecretion) of TSH will motive hyperthyroidism. Thyroids caused by the pituitary gland is much less not unusual though, accounting for much less than 10% of all hypothyroidism instances and much less than 1% of hyperthyroidism instances.
