Continuous Glucose Monitoring (CGM) is a small, wearable device that tracks your blood sugar levels continuously throughout the day and night. CGMs provide real-time data, alerting you when your glucose levels are too high or too low. This helps in better diabetes management by showing how your body responds to food, exercise, medication, and stress. This device can be especially helpful for people with Type 1 or Type 2 diabetes who need close glucose monitoring and want better control of their health. However, using a CGM when it’s not medically necessary may lead to unnecessary anxiety or over-monitoring, especially if your blood sugar levels are generally stable. Talk to your doctor to see if a CGM is right for you.
