Can a tiny sensor predict dangerous sugar crashes?

This study aimed to see if a continuous glucose monitor (a small sensor worn on the body) could help predict when people with type 2 diabetes are at risk for dangerously low blood sugar. 41 participants, considered at either high or low risk for these episodes, wore monitors that either showed them their glucose levels or kept the data hidden. The goal was to gather information to help doctors better predict and prevent these risky events in the future.
