A<unk>  is a disorder primarily affecting the<unk>  gland. The main disorders involving the<unk>  gland are: Condition Direction Hormone Acromegaly overproduction growth hormone Cushing's disease overproduction adrenocorticotropic hormone Growth hormone deficiency underproduction growth hormone Syndrome of inappropriate antidiuretic hormone overproduction vasopressin Diabetes insipidus (can also be nephrogenic) underproduction vasopressin Sheehan syndrome underproduction any<unk>  hormone Pickardt-Fahlbusch Syndrome underproduction any<unk>  hormone, except prolactin, which is increased Hyperpituitarism (most commonly<unk>  adenoma) overproduction any<unk>  hormone Hypopituitarism underproduction any<unk>  hormone Overproduction or underproduction of a<unk>  hormone will affect the respective end-organ. For example, insufficient production (hyposecretion) of thyroid stimulating hormone (TSH) in the<unk>  gland will cause hypothyroidism, while overproduction (hypersecretion) of TSH will cause hyperthyroidism. Thyroidisms caused by the<unk>  gland are less common though, accounting for less than 10% of all hypothyroidism cases and much less than 1% of hyperthyroidism cases.
