Right, you've described my current plan - to eliminate it entirely for a while to see what happens, then slowly reintroduce things to see if I get any reactions. Besides the IgG test some of my own observations were acute reactions in my mouth from certain cheeses, and things like that - so I'm certain there's some kind of allergic reaction to... something going on. (The test I took specifically did show that casein was the problem in my case. We'll see.)

And agreed that stress can cause those issues with the gut - and for me at a minimum exacerbates other things already going on - but yeah, I'm seeing and hearing a lot about how it goes the other way but I'm not seeing the science or experiencing it yet in my case.

Also - in my situation the autonomic dysfunction has a strong biological component. I have postural tachycardia and peripheral neuropathy caused by a genetic collagen issue (Ehlers-Danlos), so I know that there are major physiological factors going on and contributing to all my various issues. And then stress - which is aggravated in my case by wildly fluctuating heart rate - compounds all of that, creating a whole vicious cycle of impairment. Unraveling this whole web and picking away at parts of it at a time is my current challenge. But I am pretty confident that while depression contributes in some ways to my fatigue, it's also majorly impacted by my heart rate and probably some adrenaline issues common in Ehlers-Danlos.

(I appreciate this discussion and your thoughts, by the way.)

>I'm seeing and hearing a lot about how it goes the other way

Well, you need to be careful who you listen to. There are an infinite number of dubious naturopaths (and many MDs) who buy into dubious theories and spread them. There are a lot fewer people who will tell you "stress causes burnout, which causes POTS, ANS dysfunction, depression, chronic fatigue/pain, digestive problems, etc.", even though this is based on a more correct understanding of how the body works. The USA seems particularly bad for MDs believing dubious theories, for a number of reasons.

> acute reactions in my mouth from certain cheeses, and things like that - so I'm certain there's some kind of allergic reaction

If it is an allergic reaction, it will show up on an IgE. Bear in mind, though, that some cheeses are just sharp.

>Also - in my situation the autonomic dysfunction has a strong biological component. I have postural tachycardia

The autonomic nervous system is biological/physiological, but is modulated by stress. It doesn't really make sense to separate these systems into "biological" or "psychological".

Postural tachycardia and depressed parasympathetic nervous system are typical symptoms of CFS caused by burnout from stress. I had these symptoms myself, very severely (I had periods where my digestive system didn't move at all, and where I had atrial fibrillation due to the tacycardia). However I've recovered completely from it now and have no symptoms.

>caused by a genetic collagen issue (Ehlers-Danlos)

Did you suffer from these symptoms your whole life? If not, I'm not sure how it fits. Typically CFS comes on suddenly and/or you have relapses and normal periods...if that's how your illness manifests then I don't see how a genetic collagen could explain it. Also, allergies are a different issue to a genetic collagen problem (and neither really explains depression). I have a moderately severe allergy (hay fever), but zero depression or fatigue from it.
