What's Up Docs?

BBC Radio 4 147 Episodes Jun 30, 2026

In this BBC Radio 4 podcast, Drs Chris and Xand van Tulleken are on a mission to help us take better care of ourselves. Although they are identical twins, Chris and Xand are very different and they never stop thinking and arguing about science and health. They want to lead healthy, happy lives and as doctors, they want this for everyone. Yet they tussle over how best to get there. When it comes to looking after our own health, it can be confusing. Medicine and science produce amazing new treatments and diagnostics every day and we are bombarded with so many headlines and pieces of advice; but how are we supposed to know what's really best for us and then successfully apply it to our lives? Drs Chris and Xand van Tulleken embrace this challenge; even as they marvel at the scientific breakthroughs, they grapple with the competing claims about health, wellbeing and how to live. From understanding testosterone therapies to microplastics in our diets, and the concept of 'hangriness' to the power of saying no - this podcast deals with the health stresses we all face every day, while taking on board how the decisions by corporations and governments affect all our health.
