Definition of Cushing syndrome - exogenous:

Exogenous Cushing syndrome is a form of Cushing syndrome that occurs in people taking glucocorticoid (also called corticosteroid) hormones, such as prednisone.

Causes, incidence, and risk factors:

Exogenous means caused by something outside the body. Exogenous Cushing syndrome occurs when a person takes human-made (synthetic) glucocorticoids, such as prednisone or dexamethasone, for treatment purposes (for example, to treat asthma).

In Cushing syndrome, the adrenal glands produce too much of certain hormones, such as cortisol.
