Thyroid and adrenals

I know if your adrenals are shot that has a negative impact on your thyroid function, but I also read if you take thyroid supplements (i.e.armour thyroid) with adrenal fatigue that can further deplete the adrenals? Whats the link there?

Also if bacteria "supress" the thyroid, is that just the gland, or the hormone? If someone took thyroid supplement like armour thyroid, would the bad bacteria suppress that as well, or is it just the gland? Tweet
