A Little Poisoning Along the Road to ME/CFS
Looking at my symptoms, many of which are far less these days and some are gone, it would be easy to figure that I'd just been dealing with some heavy-duty menopausal issues.

    I don't know the name of the test. It's not just a "stress test." I have one here just ran this week. No clue how to read it. I've been searching for some sort of guide and cannot find one. Does anyone know how to read one of these tests or know where an interpretive guide is? Dysautonomia MD ran it but did not explain it. Thank you!

    Was it done once, or twice? If it was done twice, once on each of two days in a row, thats the Stevens protocol, which is the current Gold Standard for ME testing.

    The critical thing is the anaerobic threshold. It tells you how fast you get exhausted.

    It was done once, but I think my once is so bad that twice is not going to matter much in this case.

    AT is 85 (HR). VO2 Max is 18.8 (VO2 mL/kg/min) and 123 (HR).

    Is AT anaerobic threshold?

    Yes AT = Anaerobic threshold. Can you give me your age so I can calculate a few things/???

    AT of 85 is not good. An age predicted HRmax would be 220 minus age, or 169. You only got to 73% of your predicted maximum ... and this was on a single round test, not a Stevens protocol, unless you haven't told us this. The result may be worst than what you have given, under the more accurate Stevens protocol. This is consistent with a major failure in energy production, but does not demonstrate this is ME. Under the Stevens protocol (presuming they would allow someone with results like this to go to day two) if there is a drop in capacity the second day, that is consistent with ME. ME (CFS in their published research I think) frequently has a drop of capacity unlike any other disease on the second day.

    The Stevens protocol may be diagnostic for ME, but a lot more work needs to be done to confirm that.

    I recently had the 2 day Steven's protocol testing done. My results came with a few more explanations attached, so if you want to compare notes or PM me to do so, that works for me. We are in a similar age range.

    This was just a test at dysautonomia MD. He was not looking to diagnose CFS. Thank you, Alex and Ruthie24. :)

    Actually I have mitochondrial dysfunction at respiratory complex 1. I am wondering if there is any suggestion for diet by the Staci Stevens folks or from anyone knowledgeable. Fats and Carb ratios perhaps?? Aerobic uses fats and O2, but anaerobic relies on glycogen and I am assuming carbs.

    would a beta blocker atrificially lower the AT and VO2 Max HR measures?

    Aerobic uses everything ... fats, carbs, protein. Fats require a lot more oxygen than carbs. Anaerobic is very inefficient, and builds an oxygen debt. That debt has to be paid back or lactic acid builds up. So you should be aiming to be aerobic, but limit activity so that you do not do much anaerobic. Carbs are the easiest way to support aerobic, but a lot of people seem to do better on a high protein diet. What is more critical in my view is the nutritional status of the food. High quality fats, not junk fats. Lean protein (to avoid excess saturated fat). Fresh fruits and vegetables. Of course if you have intolerance or allergy to a food you should not consume it ... though in the case of intolerance low doses that are regular may be fine.

    Staci Stevens, to my knowledge, does not advise much on diet but on exercise ... how to do it, and how not to. If you operate at the high end of your aerobic range for long enough you might be able to increase your anaerobic threshold - thats the theory, and for many this has happened, but there is still not much published data on this.

    Have they identified the cause of the complex one deficiency? In Parkinson's it appears to be from oxidative stress, I am not sure about other forms. Knowing the cause will tell you a lot about how to treat it. I would be very careful about making many changes to diet, or large changes, without consulting with your specialist. It may be hard to predict how that will affect a complex one problem.

    In Myhill's research, most people with CFS (probably ME, but I am not sure about that) have a mitochondrial problem, and there is evidence that most with fibromyalgia do too. The issue is that different people seem to have different mitochondrial problems in CFS, its not a uniform group - but they all result in similar symptoms.

    Thank you for your help here, Alex. I have mycotoxin illness (Real Time Lab) and probably Lyme. I have not tested to be very viral except a consistent elevated IgG for EBV. I became ill after a mold exposure. I have one of Shoemaker's multisuseptable HLA types (though so does my husband and my mother and neither are ill and both exposed to toxic mold ). My last Nutreval showed oxidative stress in good range (surprised about that one). I am low in CoQ10. I suspect methylation issues which can impact Krebs. Not sure how directly that would impact complex 1. I wonder how many people with cfs have actually tested with a buccal swab or muscle biopsy to identify mitochondrial damage? Wouldn't it make sense that if AT especially is impaired that there is mitochondrial damage or dysfunction?

    @soulfeast , sorry this may be off-topic, but I just got tested by Real Time Lab for mycotoxins and it came back positive for Tricothecene, almost positive for Aflatoxin and off the charts positive for Ochratoxin. My doctor didn't give me much information about what this meant (even though the test cost $700 and he charged me $120 to tell me the results). Do you have any insight? Is it definitely environmental? Could it be food? What do I do next? Just hoping you got better guidance than I did. Thank you!

    $120 and he didn't give you a treatment plan!:jaw-drop:

    He told me to get my house checked. My husband called a company, they are coming on Friday and it's going to cost $500. I have zero income and I was the main breadwinner in the family. This sickness is going to suck us dry until we're on the streets!

    To be fair to my doctor, he also gave me the results of my methylation blood test and told me to take methylB12 and methylfolate... but, seriously, $120 for 25 minutes on the phone to tell me what the paperwork basically told me. :(

    I would think check your house and consider other potential current exposures where someone could bring in mold spores and cross contaminate your house or if you work or frequent a possible contaminated building. Not sure it could be food, esp with tricothecenes. Ochratoxins and aflatoxins possibly through foods. I had a huge excretion of ochratoxins my last panel about a month ago and trying to figure out if food related. new exposure or an excretion. My MD has little experience with this so it's a guessing game.

    My test from Real Time showed .66ppb for Trichotthecene which is a mycotoxin from Stachybotrys chartarum aka "black mold". I ordered a Pro-Lab test kit and sent it in for analysis. It contains a a petri dish which I taped to my forced air duct for 15 minutes and then let it grow for 3 days. It grew a dark mold and I sent it in for analysis. No results as yet. My doctor who ordered the test has me taking a combination of Chlorella, Bentonite Clay and Charcoal. I have read these all are proposed as being able to absorb the Trichotthecene and then its excreted in the stool. Thats the theory. Just sarted a week ago slowly and I'm hoping it will make a difference.

    @LHCTom , please let us know your results. Ours showed nothing significant in our house. We don't have a forced air duct. I'm still at a loss for what you do to treat this.
