The only real way to know is to get a 24 hour urine cortisol test or a salvia test. Cortisol is probably the only hormone that can accurately be tested in salvia. Not to many drs measure free cortisol but that may give you a better indication of how much is bioavailable to your body. Problem with cortisol is that it can be high or low different times of the day. To play safe you may want to get an herb that is an adaptogen where it modulates cortisol levels (keeping them balanced either way). Siberian ginsing , rhodilia roscea, Phosphodyltal serosine. 500 mgs b-5, 1000 vitamin C 2-3 times a day would be a good start. When ever adrenals are imbalance thyroid will be altered evenutally. Most naturopathic drs like to see morning cortisol in the upper range if not over. >16. Few drs will give low dosages of cortisol 5 mgs BID to as a trial to see if you feel better. Next step I would do is go to a trained expert in adrenal fatigue NOt and ENDO, but an internal medicine specialist who are open minded. Do not try to diagnose this your self because it is a tricky situation and other factors may be underlying cause. (insulin/thyroid imbalance).
Ok now I need brain twister for the experts.
For the past 2 years my serum copper and ceruoplasm have been at the very low end of the spectrum 18 ng/dl (16-36), but my drs are not concerned; however I am because is it my understanding that if you have adrenal fatigue that it is the adrenals that trigger the liver to secrete ceruloplasm which excretes copper from the liver. And if my adrenals are not working properly that I could have a copper build up in the liver but have a functional deficiency in the body. I have been taking 5 mgs of copper per guidelines to raise copper levels and still it did not move. Since copper is bounded in the liver then this would displace other minerals such as zinc and iron since they compete with one another. Does this make any sense?
