Once cortisol levels reach a certain level, they block the release of both CRH and ACTH. This type of self-regulating feedback loop is called homeostasis.

You might also take an adrenocorticotropic hormone (ACTH) stimulation test. This is where your doctor tests your cortisol levels and then gives you a dose of ACTH.
