Clinicians from King’s College Hospital and King’s College London are trialling a pioneering glucose sensor inserted under the skin that could change how patients with type 1 diabetes manage their condition.

The sensor allows patients with diabetes to continuously track the level of glucose in their blood using a smartphone app, rather than needing to draw blood to test several times a day.

It is inserted under the skin through a small incision, and sends the patient’s glucose level to the app via a Bluetooth transmitter, worn on the skin above the sensor. The app also emits an alert when the level of glucose gets dangerously high or low.

The trial involves patients being treated at King’s CollegeHospital. Dr Pratik Choudhary, Consultant in Diabetes and Senior Lecturer at King’s College London, said: “Managing type 1 diabetes is often like walking a tightrope between high and low blood glucose levels, but continuous glucose sensing give patients a lot more information and helps them to manage their condition more effectively.

“New technologies such as this implantable sensor have the potential to allow patients to gain more control of their condition and vastly improve their quality of life.”

The study has now been completed and results will be presented at the international Diabetes Technology Meeting in October.

The trial has recently featured on the BBC News website. If you would like to know more about the trial, please contact Dr Choudhary at
