I don't know 100% that I have adrenal fatigue but it is a sure bet...I think it's more adrenal insufficiency which is more serious because I am dizzy on standing, no energy at all, my DHEAS level is 65.8 (range 35-430), Cortisol 20.83 (range 4-22), and Ferritin 32 (range 20-200). My BP is low and lower on standing. Should I take isocort? I am going to buy an iron pill at least, but need something to get me through the day to be functional, i.e. isocort would help?
