Ep 229 – Continuous glucose monitoring

October 22, 2026 · 15 min

Show notes

Continuous glucose monitoring (CGM) has moved from being a specialist technology used mainly in type 1 diabetes to becoming one of the most important developments in modern glucose management. What began as a way of collecting more frequent glucose measurements has evolved into a platform capable of displaying trends, predicting future glucose changes and, when integrated with insulin pumps, automatically influencing treatment. More recently, CGM has expanded into type 2 diabetes, consumer health, early diagnostic research and telemedicine, while artificial intelligence is opening the possibility of increasingly individualised prediction and decision support. At the same time, researchers are working on longer-lasting and potentially non-invasive sensors. In this episode, Dr Roger Henderson revisits how CGM developed, looks at where the technology is heading, what these advances could mean for clinical practice, and the challenges GPs need to consider as glucose monitoring becomes increasingly predictive and automated.
