So just take half the dose that made me unable to stand upright for 24 hours, and keep taking it every few hours until my cortisol 'normalizes'!
If you have low cortisol on any kind of test you need cortisol most likely. Lol.
No. This is oversimplifying the problem. My cortisol levels are
normal until I'm put under stress.
Then they're low. If I were to simply take cortisol every day, that would be elevating my cortisol levels above normal the majority of the time, which comes with its own set of problems (Cushing-type symptoms). More is not necessarily better, especially where hormones are involved. Even my clueless endo suggested "just taking the cortisol when you feel especially stressed or are ill" but the idea of having those symptoms when I was already feeling awful was truly daunting.
And cortisol isn't something you can go without if you are lacking.
Again - it's not low all the time. Just when my body is under significant stress. The rest of the time, it's normal.
The body isn't like a granary with wheat and rye and barley saved for winter, and if one barrel gets low, you just go to another store to purchase some more to top them off. This mechanistic view (x is missing, add x) is not conducive to good health in more complicated issues.
Hypothesis:
1) I take hydrocortisone.
2) My cortisol levels rise far above normal.
3) This sends a message to the pituitary: 'stop producing ACTH!'
4) I make little to no ACTH in the first place (this and other pituitary hormones are what's really out of whack.)
5) The pituitary stops producing any ACTH at all. After all, there's way too much cortisol!
6) Cortisol begins to drop like a stone.
7) This is a stressor! The body waves all its red flags (very technical, I know)
8) Cortisol drops even lower because of stressor.
9) Pituitary belatedly realizes it should probably be doing something about this and kicks back on, but it doesn't produce a lot of ACTH at once.
10) Slowwww gain of endogenous cortisol again
...which is why it takes a few days to recover. Just a guess.
