FDA Approves First Wearable That Tracks Both Blood Sugar and Ketones
What Happened
The US FDA has authorized Abbott’s Libre Duo 10 Day, the world's first wearable device that continuously monitors both blood sugar (glucose) and ketone levels using a single sensor. Designed for people with diabetes aged 2 and above, the device sends real-time readings and alerts to a smartphone app.
Key Takeaways
The wearable could help detect rising ketones early and prevent diabetic ketoacidosis (DKA), a potentially life-threatening diabetes complication. Unlike traditional blood or urine ketone tests, the device provides continuous monitoring and automatic alerts when ketone levels become concerning. The FDA's decision was supported by six clinical studies involving more than 600 participants.
