Quantum Biology 10: Hormones 102
Two years ago I gave you the Hormone 101: Clinical thoughts revealed blog post. That was a small dose of reality at the beginning of this journey. There was some foundational hormone biochemistry there given to you in simple terms. Most people jumped all over the free T3 link to pregnenolone in the post. They thought that "their cure" for hypothyroidism and/or chronic pregnenolone steal syndrome was increasing free T3 or just lowering reverse T3 to raise pregnenolone. So what was not observed? A trip down memory lane for the hormone cascade Leptin resistance occurs first in the brain. Then insulin resistance happens soon their after in the liver, gut, and peripheral tissues. This eventually leads to adrenal resistance. This resistance occurs at the PVN in the brain. (Brain Gut 16: Adrenal Fatigue Rx) It does not happen in the adrenal gland. What happens is that the outflow from our sympathetic system in the brainstem overwhelms the parasympathetic nervous system. This increase in overall cortisol initially, is the stress hormone that allows for fight or flight syndrome (life or death). As this condition persists chronically over time, cortisol levels decrease and flatline on adrenal stress index testing.
