How long does it take to get cortisol results back?
If the adrenal glands are functioning normally, then cortisol levels will rise with the ACTH stimulation. If they are damaged or not functioning properly, then the cortisol level will be low. A longer version of this test (1-3 days) may be performed to help distinguish between adrenal and pituitary insufficiency.
What happens when ACTH is low?
A decline in the concentration of ACTH in the blood leads to a reduction in the secretion of adrenal hormones, resulting in adrenal insufficiency (hypoadrenalism). Adrenal insufficiency leads to weight loss, lack of appetite (anorexia), weakness, nausea, vomiting, and low blood pressure (hypotension).
