That's weird they didn't tell you anything, not even a warning that you're headed towards adrenal insufficiency like if you had hyperglycemia they would warn you're headed towards diabetes.
How many doctors at Mayo did you deal with? Did you show your test results to other doctors outside Mayo and what did they say?
As you mentioned in your PM about the pancreas giving out and causing diabetes, that's what I assume alt medicine means with AF, but most people diagnosed with AF have higher than normal cortisol levels, including me, and that's what finally switched my opinion about AF existing or not, because my adrenals are obviously working fine if they are pumping out higher than normal levels of cortisol!
I know some will say that just like high blood Sugar
will eventually wear out your pancreas, your adrenals will eventually wear out from "over-use" from too much stress, but just like with type II diabetes, correct the high blood Sugar
and the pancreas will start functioning normally again and there's no need to "rebuild" your pancreas with supplements. That's my biggest worry about "AF", if there's nothing physically wrong with your adrenals, trying to "rebuild" them is a waste of money and possibly can be harmful with all the questionable supplements and glandulars out there. I think most of the adrenal-supporting supplements are merely stimulants no different than caffeine.
Did they check your pituitary for maybe causing secondary adrenal insufficiency?
