Microbiome Medics
Dr Siobhan McCormack and Dr Sheena Fraser are the Microbiome Medics, two GPs who believe that the rapidly emerging science of Human Microbiomes presents a paradigm shift in the way medicine is perceived, researched, and practiced.
The Microbiome Medics Podcast is the place where clinicians, scientists and anyone else can learn about Human Microbiomes, Lifestyle Medicine, how they connect and how they can be harnessed to improve health outcomes.
Join our two intrepid Microbiome explorers as they unearth the evidence and present the multiple ways in which the trillions of microbes living in and on you can impact your physiology and health.
This podcast will escort you through the basics, explain the research, introduce you to the experts and package the latest evidence into actionable, bite-sized chunks that you can use today to improve your own health and the health of your patients.
Our only declaration of interest is that we have co-created "the gut microbiome for clinicians", an online course for busy health professionals with over 30 hours of learning available at http://bslm.org.uk/

The Gut, Brain and Chronic Pain
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.This podcast is brought to you in collaboration with the British Society of Lifestyle Medicine.Disclaimer:The content in this podcast is not intended to be a substitute for professional medical advice, diagnosis, or treatment.
