Addison's Disease Support Group
Addison's disease (also known as chronic adrenal insufficiency, or hypocortisolism) is a rare endocrine disorder. It is estimated that it affects about 1 to 2 in 100,000 people. It occurs when the adrenal glands, seated above the kidneys, fail to produce enough of the hormone cortisol and, sometimes, the hormone aldosterone
A blood draw for cortisol levels is not reliable except for the exact time the blood draw is given. You would need a early AM to late PM saliva test to determine your cortisol levels throughout the day, not just at blood draw time.
