Also, lemme explain what Polyglandular Addison’s Diseaseis.
A disorder in which the adrenal glands don't produce enough hormones.
Specifically, the adrenal glands produce insufficient amounts of the hormone cortisol and sometimes aldosterone, too. When the body is under stress (e.g. fighting an infection), this deficiency of cortisol can result in a life threatening Addisonian crisis characterized by low blood pressure.
