The Gut Health Podcast

• Tailored to the Core: Breathing, Bloating and Precision Medicine

  Dr. Iris Wang of the Mayo Clinic shares cutting-edge insights on gut health across the lifespan, including advancements in pharmacogenomics for personalized medication selection and innovative breathing techniques to relieve abdominal distension. She busts common myths about bloating, revealing how diaphragmatic dysfunction rather than excess gas may be the culprit. Dr. Wang also emphasizes the importance of starting gut health education early, helping kids and parents alike understand that pooping shouldn't be painful or forced. • How pharmacogenomics helps identify why some patients metabolize medications differently, leading to better medication choices with exploration on the hope and/or hype of precision medicine in the GI world (Wang et al 2019)• Explanation of abdomino-phrenic dyssynergia (APD) – when the diaphragm moves downward instead of upward, causing visible abdominal distention• Specialized breathing technique developed in Barcelona that retrain the diaphragm for bloating relief (Barba E et al 2024) - see video link below• The importance of normalizing healthy pooping habits from childhood through education & tools like toileting stools (e.g. Squatty Potty)• Warning signs for parents about childhood constipation – including stool leakage, straining, & urinary problems (Tran DL et al 2023)• How yoga can support gut health through mindful movement, core engagement, & stress reductionYoga videos:Yoga For Digestion Flow| Yoga With Adriene (26 mins)Yoga for Bloating, Digestion, Ulcerative Colitis, IBD & IBS (12 mins)Check out Dr. Wang's children's book Boo Can't Poo, which helps normalize healthy pooping habits for kids while educating parents too.References:Wang XJ, Camilleri M.

• Fermented Foods for Gut Health: Myths vs Science

  Fermented foods offer surprising health benefits with science showing they can increase gut microbial diversity in ways other dietary interventions cannot.• Expert Elisa Caffrey clarifies what qualifies as fermented food: substrate + microbes + time• While touted as a source of probiotics, most fermented foods don't technically contain probiotics, which require specific strain characterization and known health benefits•Different types of fermentation are used in food production: lactic acid bacteria ferment carbohydrates in sauerkraut and yogurt; acetic acid bacteria oxidize ethanol into acetic acid in kombucha; and filamentous fungi such as Aspergillus oryzae and Rhizopus species are involved in the fermentation of miso and tempeh, respectively.• Fermented foods may benefit gut health through microbial derived metabolites rather than just the microbes in the food or beverage.• Consider starting with yogurt if you are a newcomer and have fun exploring kimchi, sauerkraut and other options for fermented food variety.• Most fermented foods are safe, though some considerations exist for those with histamine intolerance or sodium restrictions• Variety is key – consuming diverse fermented foods appears to help maximize potential benefits• The fermentation process may have mental health benefits beyond nutrition though more research is neededTry incorporating fermented foods gradually into your diet and experiment with different types to find what works for your body and taste preferences. Let us know what makes your taste buds (and gut) happy! This episode has been sponsored by Activia.

• Pelvic Floor PT Explained: Who Needs It and Why?

  Pelvic floor physical therapy (PFPT) is a crucial yet often overlooked component of gut health that can dramatically improve quality of life for people suffering from bowel issues, bladder problems, or pelvic pain. Dr. Alicia Jeffrey-Thomas joins us to demystify and normalize this specialized therapy and explain how proper pelvic floor function impacts everything from constipation to sexual health.• Understand that daily bowel movements don't necessarily mean you're not constipated• What happens during a PFPT session and how therapists create a safe + comfortable environment• The importance of proper pooping position• Why breathing techniques and sounds (like mooing!) can help relax your pelvic floor during bowel movements• Demystifying tools like pelvic wands and dilators for at-home maintenance • How dyssynergic defecation affects approximately 50% of people with constipation and how pelvic floor PT can help• Why all women can benefit from pelvic floor PT after childbirth (and even during pregnancy)•  Men face pelvic health issues too, like post-prostate surgery incontinence • The downside of "peeing just in case" and how it trains your bladder to signal fullness prematurelyIf you've experienced pelvic floor issues, don't accept them as normal - seek help from a pelvic floor physical therapist who can address these problems and improve your overall quality of life.References and Resources:Rao SS, Patcharatrakul T.

• Living with IBS: How to Manage Symptoms Without a Major Diet Overhaul

  Join us as we discuss effective non-diet focused methods for IBS relief. In this episode, Kate and Dr. Riehl review key factors on how gender can influence common symptoms of IBS.Hormones significantly influence IBS symptoms, with women being diagnosed 2.5 times more often than men, in part due to differences in gut function and pain perception. This episode features the following key discussion areas:• Women's fluctuating estrogen and progesterone levels affect gut motility and pain sensitivity throughout the menstrual cycle• Visceral hypersensitivity causes normal digestive sensations to be interpreted as pain - like a car alarm going off unnecessarily• The "microgenderome" refers to gender differences in gut microbiome that may contribute to women's higher rates of IBS and autoimmune conditions• Gut-directed hypnotherapy helps reprogram the subconscious mind to interpret gut sensations more accurately, with 70-80% improvement rates• Pelvic floor physical therapy can help address muscle tension that contributes to both constipation and diarrhea symptoms• Non-diet approaches including medications, supplements like enteric-coated peppermint, and lifestyle factors are effective IBS management tools• Regular exercise (especially in nature), adequate sleep, and stress management techniques complement other treatmentsFor more information on IBS-C treatments, check out our dedicated three-part series in episodes 14, 15, and 16.This podcast has been sponsored by Ardelyx and Nerva by Mindset Health.References:Mulak A, Taché Y, Larauche M.

• Is a leaky gut really the root of your ailments? Here’s the science.

  Is "leaky gut" real or just another wellness buzzword? In this episode of The Gut Health Podcast, we cut through the controversy with Dr. Alessio Fasano, a renowned gastroenterologist and microbiome expert from Mass General Brigham. Dr. Fasano explains what happens when the gut’s protective barrier is compromised, resulting in increased intestinal permeability, and how this can affect not only gut health but also overall well-being. While some level of intestinal permeability is essential for health, in the presence of an altered gut microbiome, it can allow harmful molecules such as bacterial endotoxins and undigested food particles to pass through the intestinal lining. This can lead to inflammation, immune system activation, and may contribute to a variety of health issues, including autoimmune diseases, gastrointestinal disorders, heart disease, and more. We explore the molecular mechanisms that control intestinal permeability, examining how factors like epigenetic changes, diet, stress, and environmental factors can all impact the integrity of the gut barrier. Dr. Fasano breaks down the latest research on how intestinal permeability interacts with the immune system and other organ systems, highlighting the complex bidirectional relationship between gut health and overall wellness. Join us as we explore cutting-edge research on gut health, from breakthrough treatments to personalized diets and biomarkers for gut permeability. Tune in for expert insights and practical strategies—like a plant-forward diet and stress management—to strengthen your gut and overall well-being. References:Effects of dietary components on intestinal permeability in health and disease. Unfermented B-fructans Fibers Fuel Inflammation in Select Inflammatory Bowel Disease Patients. High FODMAP diet causes barrier loss via lipopolysaccharide-mediate mast cell activationA Randomized Placebo-Controlled Trial of Dietary Glutamine Supplements for Post-Infectious Irritable Bowel Syndrome.Bovine Colostrum in Increased Intestinal Permeability in Healthy Athletes and Patients: A Meta-Analysis of Randomized Clinical Trials. What to do about the leaky gut?Learn more about Kate and Dr. Riehl:Website: www.katescarlata.com and www.drriehl.comInstagram: @katescarlata @drriehl and @theguthealthpodcastOrder Kate and Dr. Riehl's book, Mind Your Gut: The Science-Based, Whole-body Guide to Living Well with IBS.
