I have never had the gut test you referred to. I never discussed this with a naturopath. I simply did some reading.
Yet I did get dramatic results which stopped my internal stinging, burning and zapping inside my skin by giving up processed sugar and limiting gluten. Yet this was not my GD pain and itching, this was head to toe 24/7 misery. This I believe was related to my Allergic Contact Dermatitis inflammation that even with Patch test results and contact control was still present. My diet starved out the yeast living in my gut which pass their waste products though my aging intestinal linings and thus raise inflammation. I read The Yeast Connection Handbook by William Crooke, MD a pioneer promoting gut health to control our internal inflammation which leads to many diseases, not only eczema. I do eat a processed sugar free, unflavored probiotic yogurt whole milk daily to help keep the good bacteria healthy to control the bad bacteria. You are on a strict diet which I assume also includes zero processed sugar, ever. I never overdid sugar like some, but I believe killing the yeast off totally was the key. Yeast doesn't die willingly and it takes months of misery, actual withdrawal because starving yeast sends screaming messages to our brains to be fed- sugar, sugar, sugar! Plus if you reintroduce certain foods it will grown back and live happily in your intestines. It took me 2 months to be certain it was helping. I've been on the maintenance plan now for 2 years and am so happy to be pain free inside my skin I will never go back to "normal" eating. Now I can have a few serving of fruit and gluten a few times a week. Plus certain non gluten carbs. How long have you been on this anti-inflation diet?
If chelation didn't help your GD it may be unrelated to heavy metals, which sadly is the case for half of us from reading these blogs. It seems from these blogs if we get relief and begin going into GD remission it happens fairly fast. I was certain I was going into remission within a month. It still took over 6 months or longer for all the no longer active papuales to release. If you find more about the dysbiotic bacteria please share what you learn.
How did you know you had mercury and other heavy metal poisoning? I never was tested for mercury, but I had a blood test for metals and learned I am allergic to: aluminum, nickel, chromium and 2-3 others I never heard of. My test was to find out it I could have a knee implant and there are no metal ones on the market I would not react to because even titanium, which I didn't react to has traces of other metals in it.
