    Episode 87: SIBO Isn't One Condition: What My New Published Review Says

    My literature review on SIBO has been published in the Journal of the Australasian College of Nutritional and Environmental Medicine for Gastrointestinal Awareness Month, and in this episode I unpack what it means for anyone stuck in the SIBO treatment cycle. The big idea: SIBO isn't one condition. It's three gas phenotypes, hydrogen, methane (IMO) and hydrogen sulfide, each driven by different organisms, picked up by different testing, and needing genuinely different treatment. Treat them all the same, and relapse is almost predictable. There's also a short segment near the end for the practitioners listening. 📄 READ THE FULL PUBLISHED REVIEW:  ⏱️ Chapters 00:00 — Welcome00:55 — Something a little different today (the news)03:01 — SIBO is not one condition: the three phenotypes07:12 — Why this changes everything: testing, treatment and relapse12:54 — For the practitioners listening22:14 — Closing thought + where to from here Key Takeaways SIBO isn't one condition. It's three gas phenotypes: hydrogen, methane (now called IMO) and hydrogen sulfide.Different gas, different organism. Hydrogen points to bacteria, methane to archaea, hydrogen sulfide to sulfate-reducing organisms, and they don't respond to the same treatment.Testing has to match. A breath test that only measures hydrogen can miss the other two, which is how you can be told you're "fine" while you're still struggling.Phenotype mismatch drives relapse. Treating every SIBO the same way is a major reason symptoms keep coming back.Eradication isn't the finish line. Lasting results come from restoring how your gut actually works, not just clearing the overgrowth. Restoration over restriction. For the Practitioners Three phenotypes, three organisms: hydrogen (Proteobacteria, ~50–60%), IMO (the archaeon M. smithii, ~25–30%), and hydrogen sulfide (sulfate-reducers, least studied).Recurrence is the core problem: reported as high as 44% within nine months of antibiotic eradication in unstratified cohorts.Motility is the throughline: the MMC is the principal defence against overgrowth, and the evidence supports prokinetic support alongside antimicrobials, not after.Post-infectious autoimmunity: ~1 in 5 develop anti-CdtB antibodies cross-reacting with vinculin after gastroenteritis. Anti-vinculin testing is not currently available in Australia.Phenotype-specific evidence: hydrogen, berberine-containing protocols ranked highest in the 2025 network meta-analysis; IMO, rifaximin–neomycin or stabilised allicin; hydrogen sulfide, bismuth subcitrate and emerging Codonopsis evidence.Combination over monotherapy carries the strongest evidence, with mucosal terrain addressed alongside eradication.

    Episode 86: Who's Actually Qualified? AI, Influencers & Why Real Practitioners Still Matter

    This week, Karly takes a viral Instagram post, one about supplement prescribing, qualifications, and the TGA  and turns it into a raw, honest conversation about who you're really trusting with your health. She unpacks the supplement free-for-all online (yes, including the parasite cleanses), why people are reaching for AI and influencers in the first place, and what's genuinely lost when you swap a real practitioner for a chatbot. A grounded, no-fear-tactics episode on the difference between health information and health care and why, in a world of endless content, a real human who knows how to think still matters more than ever. Key takeaways: Why people aren't foolish for turning to AI or influencers, they're exhausted and underserved, and that matters in how we talk about this.Health information and health care are not the same thing and the line between them has never been blurrier.What TGA regulation actually does, and the hidden risks of buying supplements from overseas without practitioner oversight.The parasite-cleanse problem: how fear gets dressed up as a solution by the same people profiting from the sale.What a real practitioner can do that a bot structurally cannot; proper case-taking, clinical reasoning, accountability, and the therapeutic relationship.How to use AI well; bring it to your appointment, use it to ask better questions, but don't ask it to do the synthesis.A direct word to practitioners: your critical thinking is your moat. Build it before you lean on the tool.This is a sensitive area for many women navigating their gut health alone after being dismissed by conventional care. If that's you — proper, qualified support exists, and you deserve it. 📩 WORK WITH KARLY Ready to stop managing symptoms and start rebuilding?

    Episode 85: Meet Your Microbiome: The 100 Trillion Guests Running Your Health

    EPISODE SUMMARY If you've ever wondered what the microbiome actually is, and why every practitioner seems to be talking about it, this is the episode to start with. Karly Raven breaks down what's living in your gut, why diversity is the number that matters most, what's disrupting it for so many women, and what it actually takes to restore it. This isn't a 30-second explainer. This is the full picture, with the clinical context, the honest caveats, and the practical starting points that most gut health content skips. KEY TAKEAWAYS Your microbiome contains around 100 trillion microorganisms and their diversity directly shapes your digestion, immunity, mood, skin, hormones, and moreDysbiosis is driven by far more than antibiotics: chronic stress, processed food, restrictive diets, and gut infections all play a roleDiversity is the metric that matters most. A high-diversity microbiome is more resilient, more anti-inflammatory, and better at restoring itself after disruptionThe most evidence-based way to increase diversity is to eat 30+ different plant foods per week. Variety matters more than quantityRestoration is not just about food. Sleep, movement, and nervous system regulation are all essential parts of rebuilding microbiome healthIN THIS EPISODE Part 1: What the microbiome is and why it mattersPart 2: The most common drivers of microbiome disruptionPart 3: Why diversity is the key metric to focus onPart 4: Evidence-based strategies to restore and rebuildREFERENCES Sender R et al.

    Episode 84: Why Does My SIBO Keep Coming Back? Understanding SIBO Relapse and IBS Flare-Ups

    If you’ve treated SIBO and felt better, only for your symptoms to return — you’re not alone. SIBO relapse and recurring IBS flare-ups are extremely common. Many people complete a round of antimicrobials, follow a strict low FODMAP diet, or take targeted supplements, and experience temporary improvement. Then the bloating, discomfort and food sensitivities slowly return. So why does SIBO keep coming back? In this episode, I explain the most common reasons for SIBO recurrence, including unresolved motility issues, long-term restriction without rebuilding digestive resilience, reduced digestive capacity, and the role of the nervous system in gut function. If you’ve been wondering: • Why does my SIBO keep recurring? • Why do my IBS symptoms flare up again after treatment? • Is low FODMAP enough to heal SIBO? • How do I prevent relapse long term? This episode will give you clarity. If you’re ready for structured, long-term support to rebuild digestive resilience, applications are open for the 6-Month Nourished Gut Program.
