Anyway. Well the piss test would be best but easier to start you can do labs.
Important one is AM Cortisol. Just do within 1 hour of getting up in morning.
And if you’re not on DHEA supplements, you can do dhea-s
If both these test are on the low end , your adrenal are not working properly.
Then there’s this but that’s if you really think you have adrenal insufficiency and you would go to endocrinologist.
The am Cortisol test is just a lab test and I would do that first.
Cuz if your cortisol is low that would explain the low energy and a lot of other things. And if it is low they would prescribe some type of hydrocortisone tablets.
