Using GI-Map in Clinical Practice – Dr David Brady

Dr David Brady shares his clinical experience of the GI-Map test in practice. He uses the ‘4-R’ principles as a useful guide to engage in an effective clinical process for appropriate diagnosing and sequencing of patient recommendations and treatment protocols.


Video Transcript…

Some of the things I engage in most after reviewing GI-Map testing is really looking at the application of what I mentioned previously, the 4R program, and trying to optimize gut function.

 1. Remove

The first R in that is remove. If there are microbes that are there at higher numbers than we want there, pathogens are opportunistic, we might want to remove those. So in that case, we would look to antimicrobial agents and I favour natural based ones using standardized botanicals or herbals and/or volatile oils. When the designs for health line, for instance, I use a lot of product called GI Microb-X, which is a multi-herbal, broad-spectrum GI anti-microbial and our Oil of Oregano. At times, I also use Berbevail as well. They’re all really good GI anti-microbials.

2. Replace

00:59 There’s a replace segment, which is the next R. That would be replacing any digestive enzymes. If the pancreas was not putting out enough of those to adequately digest one’s food.

3. Re-populate / Reinoculate

01:13 And then repopulate, reinoculate, people use different jargon there, but that’s basically fortifying the commensal, or the good bacteria, basically with probiotics and prebiotics. The probiotics would be the ProbioMed 50. ProbioMed 100 would be a stronger one. FloraMyces is a Saccharomyces cerevisiae boulardii product that can serve as a sort of a probiotic and a prebiotic in a way. The enzyme product would be called Zymegest to supply all of the different pancreatic enzymes for food digestion.

4. Repair

01:47 And then finally, repair, is the final R. Repair implies that you’re going to reconstitute a better state of affairs on the GI lining or the mucosal lining. So if there’s inflammation, if there are signs of hyperpermeability, we would use things to help tonify and to help heal up the gut lining, reduce the inflammation, stop antigen-antibody blocking that might be driving the inflammation along the mucosal lining. The flagship product for that would be GI Revive powder.

02:22 The GI-Map test has been a Godsend to my practice, right? I can’t imagine practising without it now. I did before because it hasn’t been around as long as I’ve been in practice, but I leaned on older technology. Stuff that couldn’t tell you as much just by the limitations of the methods, so old culture-based technologies and even the first-gen molecular DNA tests had limitations. NextGen sequencing has significant limitations to make clinical decisions.

02:50 So now we have this tool at our disposal and if you combine the information you extract from that, the objective very high-tech scientific data with the story that the patient tells you, right? With their symptoms, with their personal medical history, with their family medical history, you can connect dots that you were never able to before and you can really practice preventive precision personalized medicine for that specific individual, sometimes to treat the thing they already have but what I’m most excited about is finding people who are at risk to develop specific disorders like a specific autoimmune disease because the ecology in their gut is driving them in that direction and they have the genetic propensity for it. It’s in their family history or when you test their genes, they have the propensity. If you change the landscape, if you change the milieu of their intestinal ecology you can short circuit that pathological process from ever happening.

To me, that’s preventive medicine and that excites me.
