As I recall, results weren't exciting. The exception was people with asthma.
Perhaps this suggests that any effect Buteyko has had on apparent ME/CFS is actually an improvement in generalized fatigue as a result of low oxygenation from asthma or poor breathing or COPD or somesuch condition.
There so much misdiagnosis in ME/CFS it's hard to know if any anecdotal treatment success is due to the treatment's effect on ME or whether it's affecting some other condition misdiagnosed as ME. We really can't tell at this point. Even the best and most experienced ME clinicians can't be certain of their diagnoses until we have a biomarker, although I'm not sure even a decent biomarker catches every case, so the specialists' clinical experience is still probably the best diagnostic tool.
Since something like 99.9% of PWME worldwide are self-diagnosed, or diagnosed by worthless definitions (Oxford, CDC Empirical), or by physicians with no understanding of the illness or the criteria and who do no testing to rule out other conditions, it's nearly impossible to say that some treatment won't be effective for some group of people who believe they have ME/CFS. We really don't know if 99% of us have the neuroimmune disease ME and 1% have something else or the other way around. My guess is it's closer to 50/50 worldwide, so a large fraction of us might benefit from treatments that appear to have no logical scientific basis as a treatment for neuroimmune disease.
ADs may alleviate all the supposed ME symptoms of a substantial number of patients (mis)diagnosed using Oxford criteria. So it's tricky to say no person diagnosed with, or who believes they have, ME can recover with ADs. To do so could be cutting off a lifeline for those people. That doesn't mean ADs alleviate the symptoms of the neuroimmune illness defined by the CCC or the ICC. The same could be true for any number of other treatments, mainstream or alternative. They could cure some people diagnosed with ME/CFS even if they don't cure ME/CFS, if you see what I mean
What we have is one big fat mess. Misdiagnosis and the possibility of multiple distinct neuroimmune conditions lumped under ME/CFS leads to massive confusion about what works as ME/CFS treatment. Knowledgeable, experienced ME/CFS specialists are not treating ME/CFS, per se. They are treating all the symptoms, pathogens, and dysfunctions they can find in PWME, which is not the same thing.
So while I want to roll my eyes at something like Buteyko, which has little to do with serious neuroimmune disease, curing ME/CFS, I have to acknowledge that it could indeed be effective for some subset of people (mis)diagnosed with CFS. What do I do with that? Those people should get a treatment that might help them, but it's not a treatment for ME/CFS, but
they think they have ME/CFS, but....
