How IoT Devices Transform Diabetes Data Collection

Before thee widnespreaad adoption of CGMs, diabetes management relied heavily on finger- stick measurements, typically perfomed 4- 10 times per day. These snapshots missed critical trends andd overnight parafarts. IoT devices have changed data collection in seral fundamental ways.

Continuous Glucose Monitors

Building a Predictive Model: From Data to Deployment
