Is Adrenal Fatigue the same thing as Adrenal Insufficiency?
No. The person with Adrenal Fatigue may have less severe symptoms, and there are lots of shades of gray. Here is an example from a medical site: “A significant number of patients with partial loss of adrenal function (limited adrenocortical reserve) appear well but experience adrenal crisis when under physiologic stress (eg, surgery, infection, burns, critical illness)” http://www.merck.com/mmpe/sec12/ch153/ch153b.
