Abbott has announced the FDA clearance of two new over-the-counter continuous glucose monitors (CGMs), catering to different segments of the population. The Lingo targets health-conscious consumers, offering insights into metabolism through tracking glucose levels in interstitial fluid. Designed as a wellness device, it provides data on reactions to food, exercise, and stress via a smartphone app, but isn't meant for diagnosing metabolic disorders.
On the other hand, the Libre Rio targets Type 2 diabetics who manage their condition without insulin. Monitoring glucose ranges from 40 to 400 mg/dL, it aids in lifestyle management. Abbott isn't alone in this venture; Dexcom's Stelo CGM, also FDA-cleared, targets the same demographic.
The significance of these OTC CGMs lies in their improved accessibility. Unlike traditional CGMs requiring prescriptions, these are available directly to consumers. This accessibility could benefit individuals with prediabetes or Type 2 diabetes by providing a means to monitor lifestyle changes' impact. Startups like Nutrisense and Levels extend their CGM use to non-diabetics, targeting weight loss, athletic performance, and metabolic health improvement. However, the effectiveness of CGM use in non-diabetic populations remains uncertain.
