Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken explore core issues around every aspect of our health and wellbeing.

In today’s episode, the Doctors explore core strength. When most people think of a “strong core”, they picture sculpted six-pack abs - but there’s much more beneath the surface. Chris and Xand will unpack the real meaning of core strength - what it is, why it matters, and how it's different from simply having visible abs.

They speak to physiotherapist James Moore to find out why core strength is essential not just for athletic performance, but for everyday stability, posture, injury prevention, and long-term health, and break down what we should be doing to build a truly strong and functional core - no matter your fitness level.

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken untangle the confusion around every aspect of our health and wellbeing.

In today’s episode, the Doctors explore hair loss. Chris and Xand, who've both battled the receding tide of hair loss (and the accompanying existential dread), are getting to the follicle of the matter.

They'll be digging into what causes it, how different types of hair loss affect men and women, and asking if there’s anything we can do about it. Cures for baldness are almost as old as medicine itself, but what does the evidence actually say about those treatments constantly being marketed to us?

Chris and Xand get the bald truth from Dr Christos Tziotzios, Consultant Dermatologist and Senior Lecturer at King's College London, who has recently pioneered treatments for some auto-immune forms of alopecia as well as investigating the psychological impact of hair loss in both men and women.
