The difference between CGMS and BGMS

Traditional blood glucose monitoring systems (BGMS) require you to stop and check your blood sugar at set times, with a finger prick. In contrast, a Continuous Glucose Monitoring System (CGMS) checks your glucose levels around the clock automatically. With a CGMS, your readings are sent straight to an app on your phone in real time, so you always know where your glucose levels are heading without needing to do anything.
