I am wondering this because sometimes I can tell my cortisol is really low and sometimes it doesn't seem to be as low. Could this be caused by hashi's, or its antibodies? Supposedly I don't have much thyroid to produce, but maybe the antibodies? I would love it if someone could simplify the thyroid-cortisol connection for me. I've tried to learn but then my head just decides it wants to fog over. I know the adrenals are involved too, along with sex hormones, I just can't get it all figured out...I used to be smarter than this. If anyone would care to put it in some kind of simple order? I know I'm asking a lot. This post was brought on by my stim test coming back in the mail saying "normal", no adrenal insufficiency. So I guess being confused a lot and being in bed a lot is normal? This is crazy.
