Every 12 years, our skeletons undergo a complete transformation.

Prof. Tim Spector and Prof. Cyrus Cooper discuss how to avoid Osteoporosis, a condition where bones become fragile, significantly increases the risk of fractures from minor incidents, often without any noticeable symptoms. Worldwide, it affects one in three women and one in five men over fifty, leading to pain, potential disability and loss of independence.

In today’s episode, Jonathan, Tim and Cyrus ask the question: How can understanding osteoporosis and implementing targeted lifestyle changes enhance bone health and reduce the risk of fractures?

Cyrus Cooper is a Professor of Rheumatology at the University of Southampton, where he is also the Director of the MRC Lifecourse Epidemiology Unit and Vice-Dean of Medicine. In addition, he’s a Professor of Musculoskeletal Science at the Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences at the University of Oxford.

Tim Spector is one of the world’s top 100 most-cited scientists, a professor of epidemiology, and scientific Co-Founder at ZOE. Tim trained originally in rheumatology and epidemiology.
