In a new podcast from BBC Radio 4, Chris and Xand van Tulleken explore the messy and complicated world of health and wellbeing.

Chris and Xand are identical twins (although Xand is seven minutes older...). They’re also both doctors and became interested in medicine at the same time. But they got into medicine for different reasons and studied different specialties. So, even though health and wellbeing is very much a shared interest, they come at it from different angles.

In What’s Up Docs? Chris and Xand are embarking on a new podcasting odyssey, sailing into the often confusing world of health and wellbeing. But who are Chris and Xand to be steering such a ship? They're here to tell you a little bit more about themselves - meet the docs!

In this BBC Radio 4 podcast, Drs Chris and Xand van Tulleken are on a mission to help us take better care of ourselves.

When it comes to looking after our own health, it can be confusing. With new statistics and treatments coming out every week, it feels impossible to decide what works best for us. So each episode, Chris and Xand are joined by an expert guest to examine the latest science, insights and data, to help you navigate the overwhelming amount of information and advice out there.

From willpower to hunger, from dodgy knees to bad breath, they'll sort fact from fiction and tussle over their understanding of it all.

And Chris and Xand want to hear from you. What are your health and wellbeing worries and wonders? You can email us at [email protected] or WhatsApp on 08000 665123.
