More than 2,000 years ago, Hippocrates suggested all disease begins in the gut. He was mostly right, and we’ve talked about the gut many times on this podcast – in relation to athletic performance, optimising the gut microbiome, and even how to use probiotics. But a couple of weeks ago I realized that we’ve never talked specifically and in depth about exactly what to do when you have a gut problem. GI issues are where I started my health journey, and probably bring more clients through our doors than any other condition, and they can affect absolutely anyone - athlete or not. On this podcast, NBT Scientific Director Megan Hall and I are talking about the steps to take when your gut isn’t working right. We talk about how things tend to go awry in the first place, signs and symptoms that you have a gut problem, and the first things to try to get quick relief. Megan also discusses the most scientifically-validated lifestyle modifications, supplements, and lab tests to try, as well as the pros and cons of using antimicrobials. Be sure to follow along with Megan’s outline for this podcast.  Here’s the outline of this interview with Megan Hall: [00:00:58] How Megan fixed her gut.
