Biosensors that measure glucose are now available without a prescription. In a CNET article about a journalist's month-long experience with a continuous glucose monitor (CGM), AACE President Elect, Scott D. Isaacs, MD, FACP, FACE, offers key insights. He reassures that glucose spikes can be normal for people without diabetes after meals and shouldn't be overinterpreted. Dr. Isaacs highlights the benefits of CGMs as they provide more precise information than traditional A1C tests and can motivate people to take control of their health, while emphasizing the importance of understanding the device's limitations.
