    Q&A. Why Do I Feel More Bloated on a Low FODMAP Diet?

    A low FODMAP diet is often used to reduce bloating, so why might your symptoms get worse after starting one? In this short Q&A episode, Joanne explores three possibilities: eating more sulfur-rich foods, replacing wheat with higher-oxalate ingredients, and changes in gut motility, including the migrating motor complex. She explains why it’s worth looking at what has changed in your diet instead of simply pushing through worsening bloating. In this episode: How food swaps on a low FODMAP diet may increase your sulfur or oxalate intakeSymptoms Joanne suggests watching for alongside bloatingWhy the migrating motor complex may matter when bloating persistsWhy a SIBO test can help clarify what may be going on✨ Want more?

    Q&A. Why Do I Feel Sick from Taking N-Acetylcysteine?

    NAC can support glutathione production, respiratory health and biofilm disruption—but some people experience nausea, headaches, brain fog, fatigue or bloating after taking it. In this Q&A episode, Joanne explains how reactions to NAC may be connected to sulfur intolerance, hydrogen sulfide production, gut dysbiosis, biofilm disruption and sensitivity to its mucolytic effects. You’ll also learn why feeling worse doesn’t necessarily mean NAC is working—and why a lower dose, slower introduction or different approach may be needed. ✨ Want more?

    58. Biofilms: Why SIBO, Candida & Gut Infections Keep Coming Back

    Why do SIBO, Candida, and other gut infections sometimes return—even after treatment initially seems successful? In this episode of The Histamine Well Podcast, Joanne explains how biofilms may contribute to persistent bacterial and fungal overgrowths. Biofilms are organised microbial communities surrounded by a protective matrix that can help microorganisms survive antimicrobial treatment and resist immune defences. Joanne explores the role biofilms may play in recurring SIBO, Candida overgrowth, gut dysbiosis, chronic sinus infections and MARCoNS. She also explains how bacteria and fungi can communicate, share resources and coexist within mixed-species biofilms. You’ll discover: What biofilms are and why microorganisms create themWhy SIBO, Candida and gut infections may keep returningHow biofilms can protect bacteria and fungiThe connection between biofilms, chronic sinus infections and MARCoNSHow Candida and Aspergillus form fungal biofilmsThe difference between mould, mycotoxins and biofilmsWhat the biofilm matrix is made fromHow enzymes and N-acetylcysteine may support biofilm disruptionWhy biofilm support should be introduced gradually during antimicrobial treatmentIf you’re dealing with recurring digestive symptoms or want to better understand persistent microbial overgrowths, this episode offers a clear and practical introduction to biofilms and their potential role in gut and sinus health. ✨ Want more?

    Q&A. Why Do I Feel Sick From Having an Epsom Salt Bath?

    Do you feel nauseous, dizzy, exhausted, or brain foggy after an Epsom salt bath? If a bath you hoped would help you relax leaves you feeling worse, you might wonder whether you’re experiencing a “detox reaction,” reacting to the heat or struggling to tolerate the Epsom salts themselves. In this short Q&A episode of The Histamine Well Podcast, Joanne explores possible reasons for feeling sick after an Epsom salt bath, including bath temperature, changes in blood pressure, histamine intolerance, mast cell activation and sensitivity to sulfur compounds. Epsom salts are magnesium sulfate. Joanne explains the role of sulfate in a detoxification pathway called sulfation and discusses why people use Epsom salt baths as part of their detox routines. She also shares why feeling unwell afterwards should not automatically be interpreted as a sign that a treatment is working—or a reason to push through. If you’ve been searching for answers about Epsom salt bath side effects, feeling dizzy after a hot bath, or the possible connection between histamine intolerance and Epsom salts, this episode offers a starting point for understanding your reaction and discussing it with your practitioner. ✨ Want more?

    56. Can Gut Dysbiosis Cause Anxiety & Depression? What the Science Actually Says

    Can an imbalanced gut microbiome contribute to anxiety and depression? We often think of mental health conditions as beginning solely in the brain. However, growing research suggests that the gut microbiome may also influence mood through the gut–brain axis. In this episode of The Histamine Well, Joanne explores what gut dysbiosis is and how the gut communicates with the brain through the vagus nerve, immune signalling, inflammation, stress hormones, short-chain fatty acids and neurotransmitter precursors. Joanne also examines what the research actually says about probiotics, intestinal permeability, depression and anxiety—without overstating the evidence or promising a simple cure. In this episode, you’ll learn: What gut dysbiosis means and what can disrupt the gut microbiomeHow the vagus nerve connects the gut and brainWhy short-chain fatty acids are important for inflammation and brain healthHow gut bacteria may influence the stress response and serotonin productionWhat studies have found about the microbiome and depressive symptomsWhy the evidence for depression is currently stronger than the evidence for anxietyWhat “psychobiotics” are and why probiotic benefits are strain-specificWhy gut health interventions should complement—not replace—appropriate mental health treatmentPractical ways to support microbial diversity and the gut–brain axisWhy fermented foods and some prebiotic fibres may not suit everyone with histamine intolerance or SIBOThe science supports a genuine connection between gut health and mental health, but the relationship is complex. There is no single probiotic, diet or supplement proven to resolve anxiety or depression on its own. Supporting the gut through a diverse, fibre-rich diet, appropriate prebiotic or fermented foods, regular movement, sufficient sleep and stress management may form one valuable part of a broader approach to mental wellbeing. ✨ Want more?
