Why is cortisol so important to check, and then why did- do you even look for MPO when most doctors don't?

Well, cortisol, in my opinion ...

So I've been in practice, uh, for over a decade, and cortisol is one of those markers that is prevalent in pretty much everybody and relevant in pretty much everybody, because we are just in a constant state of stress and overload in the environment that we currently live in.

Everything from our jobs to our families to how we're being exposed to blue light, how our food is no longer nutritious.

All of those things cause stress on our bodies.

That stress can be physical, mental, emotional, chemical, all of it.

When cortisol responds in the body, it's supposed to be short-lived, short-term, enough for us to get out of a dangerous situation to activate that fight or flight.

What is that?
