Overview of hyperadrenocorticism

摘要

Hyperadreno-corticism (MAC), also known as Cushing's disease, is a common endocrine syndrome that affects middle-aged and geriatric dogs and, occasionally, cats. HAC is generally caused by tumors of either the pituitary or adrenal glands; however, long-term administration of exogenous glucocorticoids can also cause HAC. Regardless of the etiology, the cause of the clinical signs typically seen in this syndrome is an abnormally elevated serum cortisol level.
