Many people living with diabetes use continuous glucose monitors (CGMs) to track their blood sugar levels. These small devices, often attached to the back of your upper arm or abdomen, send data to an app on your phone. This allows you to see, in near real-time, how your blood sugar levels spike or drop depending on what you eat or how active you have been.
The benefits for people living with diabetes are obvious, as failing to keep abreast of blood sugar levels can be dangerous. But these devices are increasingly being advertised as health aids to the broader community, including health-conscious non-diabetics and elite athletes.
