What's Up Docs?

"What's Up Docs?" is a BBC Radio 4 podcast hosted by identical twin physicians Chris and Xand van Tulleken, who bring warmth, wit, and sibling rivalry to the often confusing world of health and medical science. Each episode pairs the brothers' contrasting perspectives with insights from expert guests to unpack topics ranging from AI in medicine and microplastics to lung health, hormones, and everyday wellbeing struggles like sleep and stress.

It also explores how societal and environmental factors, from air pollution to corporate influence, shape public health outcomes. Ideal for curious, health-conscious listeners seeking accessible, engaging, and scientifically grounded conversations about self-care, medicine, and modern living, the podcast stands out for its intimate brotherly banter combined with authoritative expert interviews and real-world relevance.
