Summary

Your body has two brains. And your second brain is your gut. Many think the “gut” is only the stomach - but it’s a network of organs, working together to regulate many different areas of health. When almost half of us suffer with gastrointestinal issues, learning how these organs interact is vital to improving symptoms. On this episode, we’re joined by Dr Karan Rajan. When Karan’s not teaching his 10 million social media followers about common medical myths, he’s an NHS surgeon, operating on people’s bowels. Karan will reveal how our GI issues impact way more than just our poo. Today, we explore how the gut and brain are connected, the lifestyle factors causing gut health issues and why it’s so hard for doctors to understand IBS. 🥑 Make smarter food choices.
