That equates to roughly 288 readings in a day. Unlike a traditional fingerstick (blood glucose meters), which provide just a single glucose reading, CGMs provide continuous, dynamic glucose information every 5 minutes.
It’s not an understatement to say that CGMs have revolutionized diabetes care. You can also set the alert parameters and customize how you’re notified. Some systems come with a dedicated monitor, and some now display the information via a smartphone app, so you don’t even need to carry an extra device around with you.Īside from the constant stream of data, most CGMs can send alerts telling you when your blood sugar levels are rising too high or dropping too low. Generally, the sensors have to be replaced every 7 to 14 days.Ī small, reusable transmitter connected to the sensor allows the system to send real-time readings wirelessly to a monitor device that displays your blood glucose data.
CGM TRACKING PATCH
An adhesive patch holds the sensor in place, allowing it to take glucose readings in interstitial fluid (the fluid that surrounds cells in the body) throughout the day and night. To use a CGM, you insert a small sensor onto your abdomen (or arm) with a tiny plastic tube known as a cannula penetrating the top layer of skin. What is continuous glucose monitoring (CGM)?Ī CGM is a compact medical system that continuously monitors your glucose levels in more or less real time (there’s normally a 5-minute interval between readings).
