You are 50% microbial by cell count, and your gut microbiome is central to all aspects of your physiology and health. The Microbiome Medics think you should know where the trillions of bacteria living in your intestines come from. In this episode of Microbiome Medics, our microbiome obsessed duo discuss the importance of birth mode on gut microbiome acquisition. They highlight the massive increases in Caesarean section rates, and even chat about their own birth experiences. (Spoiler alert...it hurt) Not to be missed by anyone born by vaginal delivery or caesarian section (or both). That means you, by the way.  Get listening!
