12 Essential Health Monitoring Devices in India (10 Must-Haves + 2 Emerging Picks)

3. Continuous Glucose Monitor (CGM)

Continuous glucose monitors give near‑real‑time glucose trends by using a small sensor placed under the skin. For people on insulin or those who need tight glucose control, CGMs reduce the need for frequent finger sticks and reveal patterns like morning spikes or overnight lows. Sensors typically last several days to a couple of weeks depending on the model, and paired apps can share data with family members or clinicians for remote review. In India, CGM availability has improved and some over‑the‑counter consumer options are emerging; however, cost and sensor supply are key considerations. CGMs show trends rather than single-point perfection, so confirm important decisions with a finger-prick check when necessary. For families, CGM data can be a helpful teaching tool — showing how a tiffin’s carbohydrate load impacts glucose can guide portion choices and medication timing. Always compare sensor compatibility, smartphone support, and official import or local approval notes before buying.
