Hyperfunction and hypofunction in the anterior pituitary

Abstract

The actions and interactions of the pituitary gland and the nervous system constitute a regulatory system whereby the physiologic activity of the thyroid, adrenals, and gonads is controlled. Damage to or interference with the pituitary gland may cause hyper- or hypofunctional states resulting in devastating changes in a person's body and life. This article limits its discussion to several of the more frequently encountered pathological states, their diagnostic work-up, evaluation, and treatment.
