Overview

Pituitary disorders can be classified as hypopituitarism or hyperpituitarism depending upon the particular hormone levels. Hypopituitarism can present as the deficiency of one hormone produced by the pituitary, multiple hormones or all the hormones produced by the pituitary simultaneously. A deficiency of all the hormones is called panhypopituitarism. Hypopituitarism may present as hypothyroidism i.e. TSH deficiency, Addison's disease i.e. cortisol deficiency, hypogonadism i.e. FSH and LH deficiency, diabetes insipidus (DI) i.e. ADH deficiency, GH deficiency, pituitary apoplexy, Sheehan syndrome. Hyperpituitarism may present as hyperthyroidism i.e. TSH excess, prolactinoma leading to prolactin excess, acromegaly i.e. GH excess, Cushing's disease i.e. cortisol excess or SIADH i.e. ADH excess.
