  • Join Dr. Siobhan McCormack and Dr. Sheena Fraser on the Microbiome Medics Podcast as they host pain management consultant Dr. Deepak Ravindran. Dr. Deepak discusses the importance of a holistic approach to pain management, incorporating factors like exercise, diet, sleep, and mind-body techniques. The conversation dives into different types of pain, chronic pain's connection to the immune system, and the potential impact of microbiome and dietary interventions. Dr. Deepak emphasises patient-centered care, individualized treatment plans, and the significance of considering mood, anxiety, and past trauma experiences. Recommendations on nutrition, probiotics, and a holistic approach to chronic pain management are explored, promoting a patient-centered healthcare model.

    Dr Deepak explains the evidence behind his approach which he has made available to patients and clinicians alike in the form of his excellent book The Pain-Free Mindset. Dr Deepak is particularly fascinated by the way in which the gut microbiome influences all aspects of pain through the gut-brain-axis and how we can harness this knowledge to better understand and manage chronic pain using non-drug modalities including nutrition, sleep and mindfulness.

  • Don't miss the first of two episodes on the role of the microbiota-gut-brain axis (MGBA) in chronic pain.

    30% of the UK population suffer from chronic pain and pharmacological options have proved disappointing and even downright dangerous . Could harnessing the gut microbiome be part of new approaches for this prevalent condition? Our tireless Microbiome Medics cover the MGBA basics, marvel at brain microglia and astrocytes, and identify chronic inflammation as a major player in chronic pain. They discuss a 2023 pilot study by Sala-Climent et al. looking at the effect of an anti-inflammatory diet on measures of chronic pain.

    Part two of this podcast will include UK Pain Specialist and author Dr Deepak Ravindran, who will be talking about his Lifestyle Medicine approach to chronic pain which includes optimising the gut microbiome and nutrition.

  • In this episode we explore the fascinating vaginal microbiome. With the expertise of Professor Sarah LeBeer, a leading scientist in the field , we unravel the complexities of this unique microbial ecosystem and its crucial role in women's health. Listen in as we discuss the dominance of lactobacilli in maintaining vaginal health and their potential influence on other aspects of health and well-being. Professor Lebeer explains the dynamic shifts the vaginal microbiome undergoes across the lifespan, and the implications these changes may have on both maternal and newborn health.

    This conversation celebrates citizen science through the Isala project. This initiative not only uncovered pivotal insights into vaginal microbiome variations but also empowered women to engage in open dialogues about their vaginal health. We address the impacts of personal habits on this intriguing microbial ecosystem and how the knowledge gained may help shape diagnostics and treatments in women's health.

    To wrap up, we explore the potential of probiotics tailored for the vaginal microbiome and the challenges they present. As we sift through the confusion surrounding probiotic products, we share practical advice for healthcare professionals and patients alike on nurturing a healthy vaginal ecosystem. From diet to lifestyle choices, we offer resources and insights that encourage proactive stewardship of one's microbiome. So, whether you're a healthcare professional or simply someone interested in the wonders of the human body, this episode is packed with intriguing discoveries and actionable knowledge.

  • 'When I found myself teetering on the edge of prediabetes, I knew I needed to make a change. I chose movement, and it changed my life.' - On our latest episode, we discuss this journey with Darryl Edwards, a movement coach and author, who made this transformation. From a fascinating conversation about the Primal Play Method to an enlightening discussion on the transformative power of exercise on the gut microbiome, this episode is full of insights and inspiration.

    We also delve into fascinating research on the effects of exercise on our gut health. Darryl and I explore interesting animal studies that show how physical activity can boost the presence of beneficial bacteria and reduce the number of harmful ones. We discuss how diet and other factors associated with athleticism can enhance these benefits. We also touch on the importance of nutrition for athletes, especially in relation to energy expenditure, mitochondrial function, and the production of short-chain fatty acids.

    Finally, we explore the implications of modern sedentary lifestyles on our health and gut microbiomes. From the evolution of furniture to the advancement of technology, we discuss how our environments encourage inactivity. But it's never too late to make a change. Whether it's introducing exercise early in life, opting for outdoor activities like gardening, or just learning to move more, every step towards a more active lifestyle can have profound impacts on our health and gut microbiomes. So, join us on this journey of discovery and learn how to reclaim the joy of movement!

  • In this podcast episode, Dr Sheena Fraser and Dr Siobhan Mccormack (aka Microbiome Medics) discuss the significant impact of antibiotics on the gut microbiome. They are joined by an expert in this area Dr Anastasia Theodosiou , who is both a Microbiome Scientist and a Registar in Microbiology & Infectious Disease.

    Dr Anastasia introduces her novel term Microbiotoxicity which can be used to explain and predict the effects of antibiotics on human microbiomes. The discussion also covers other drugs like proton pump inhibitors and selective serotonin reuptake inhibitors (SSRIs) which can also perturb the gut microbiome. Listeners will gain insights into the recovery timeline of the gut microbiome after antibiotic exposure and the implications of gut microbiome disruptors like Caesarian section delivery and neonatal formula feeding on both gut health and other health outcomes across the lifespan . This episode highlights the importance considering the impact of medications on the gut microbiome and how we might start to bridge the gap between microbiome research and clinical practice.

    Dr Anastasia (Tash) Theodosiou is an MRC Clinical Research Training Fellow (University of Southampton) and an Infectious Diseases and Medical Microbiology Registrar. Her research involves the use of controlled human infection to study microbiome development in early life, including the world’s first respiratory human challenge study in pregnancy.

  • In the UK someone is diagnosed with cancer every two minutes. Every 4 minutes, someone dies of cancer. Startling statistics indeed, but did you know that human microbiomes, and the gut microbiome in particular, is pivotal to every aspect of cancer prevention, treatment response ,recovery and survivorship?

    Given the importance of the subject, your loyal microbiome nerds, Dr Sheena and Dr Shiv, have chosen to allocate not one , not two, but three episodes of Microbiome Medics Podcast to this rapidly evolving and complex area of research.

    In this first episode they get down and dirty with a cancer cell to figure out exactly how and why your resident gut micro-organisms might just be one of the most important resources you can utilise to harness the mighty power of your body’s remarkable and extensive anti-cancer systems. Dr Shiv thinks she can get you to fall in love with her favourite gut microbiome research paper and Dr Sheena gets all hot under the collar about the effect of sweeteners on gut microbiome function. Enjoy.
