Re: Could symptom this be caused by my thyroid?
I recently had saliva test done for cortisol. My 8AM was below normal, the NOON was above normal, the 4PM was normal, and the 11PM was below normal. Doing the test 4 times a day, you can see the variations - and how just one test done during the day can falsely show "normal" adrenal function. My blood work showed low normal AM cortisol because it was done in the doc's office around 10:30AM, and it stressed me just getting to the docs, so naturally my cortisol might be more elevated than it normally would. The saliva collection is done in your own home, so there's more accuracy, I believe.
I was put on 10mg CORTEF, which I take in a split dose, once in AM , once in PM. My DHEA was also low.
I guess the point I am making is that just bc one test showed your cortisol "normal" doesn't mean that your adrenals aren't fatigued. You need a bigger picture to really see what is going on.
