Hi,
I am assuming your saliva testing included testing Cortisol levels at 4 different times of the day and also DHEA-S levels? If just progesterone, the estriol and estradiol, and testosterone levels were tested then that would only detect things like estrogen dominance and low progesterone typically associated with adrenal fatigue.
If you have not read Dr. Michael Lam's website
http://www.drlam.com
then go to his section on adrenal fatigue and read all those articles, particularly Ovarian-Adrenal-Thyroid Axis and all ones on staging of adrenal fatigue, etc. On Dr. Lam's website, as well as, in another very good resource, a book by James L. Wilson entitled "Adrenal Fatigue: The 21st Century Stress Disorder", there is great information.
An astute, experienced clinician can diagnose adrenal fatigue based on your symptoms, a detailed medical history and looking at the whole picture. However, like many others, I had to endure the torment and suffering of doctor(s), who only made my condition worse and caused me thousands of dollars of medical debt, even when seeking ones who were NOT in the conventional arena (those like you mentioned who only recognize Addision's.
Under previous board certified anti-aging osteopath's (and like you, a conventional MD that I had been seeing for years as my primary) care, my adrenal fatigue deteriorated to stage 3d, near failure. My condition is very critical. I have been near collapse.
Firstly, I would suggest changing doctors. The one you have right now obviously will not even acknowledge adrenal fatigue exists for whatever reason and has nothing to offer you. I highly suggest seeking out one who is very experienced in adrenal fatigue and does not think they can just supplement the issue away, nor one that resorts solely on bio-identical hormone replacement therapy right away and does not look at you and your condition individually, bookut rather at the big picture, as there is not one area of the body that is not impacted by the intricate adrenal system.
If you suspect you have adrenal fatigue seek out adept MDs. It will not only keep your condition from deteriorating it will undoubtedly save you 10's of thousands of dollars of medical debt. I believe ones who practice high dose Vitamin C (s), (various forms) (carefully titrating to one's body responses -as with advanced cases of AF, in particular, there are many paradoxical responses)and certain B vitamins are the clinicians to seek out.
Dr. James Wilson's book has a Adrenal Questionnaire in it and also I believe Dr. Lam's website has an adrenal self test questionaire on it. I have read many, many other research articles on adrenal fatigue and also sleep deprivation and the two resources I have mentioned are by far the best.
I am no longer on licorice root. There is a time and place for each supplement and if your adrenals are too fatigued, licorice root may be too much of a stimulant.
I am not an experienced doctor. I can only share from my experiences and my own body's individual responses and from my costly mistakes in the past and from my indominatable will to survive and be well again.
May the Lord lead and guide you!
