If there is a hypo- or hypersecretion of these hormones, the result can be a number of conditions, including pituitary dwarfism, gigantism, acromegaly, sterility or diabetes insipidus. Human Anatomy & Physiology: Help and Review / Science Courses.
Causes are: (1) excessive secretion of adrenocorticotropic hormone (ACTH) from the pituitary gland, which may actually result from faulty release of corticotropin-releasing factor (CRF) from the hypothalamus or a functional tumor, usually corticotroph adenoma; (2) tumor of the adrenal cortex, causing hypersecretion of the glucocorticoids; (3) iatrogenic Cushing's syndrome resulting from excessive or prolonged administration of exogenous glucocorticoids; and in humans (4) ectopic production ...
