Who gains advantages from easy-access Continuous Glucose Monitors?
Over-the-Counter Glucose Monitors: A New Frontier for Lifestyle Management
Continuous glucose monitors (CGMs), traditionally used by individuals with diabetes, are now becoming available over-the-counter (OTC), opening up a new avenue for those without the condition to gain insights into their glucose levels and lifestyle factors.
Pharmacist Diana Isaacs supports this development, seeing potential benefits for people with prediabetes, gestational diabetes, and for educating the general public about lifestyle factors affecting glucose levels. Over-the-counter CGMs could be cheaper for uninsured individuals or those without prescription coverage, making them more accessible to a wider audience.
However, the debate about OTC glucose sensors involves their benefits and risks, particularly for adults without diabetes. The American Diabetes Association's scientific discussion, as reflected in expert opinions like Dr. Jody Dushay’s, emphasizes that for people with normal glucose regulation, these devices may not provide meaningful health benefits and can produce misleading or inaccurate readings. Normal blood sugar fluctuations after meals or exercise may be misinterpreted as pathological, potentially causing unnecessary anxiety or harmful dieting behaviors.
Furthermore, CGMs can suffer from sensor malfunctions, false alarms, and cost barriers, making them less practical or reliable for routine wellness monitoring in non-diabetics. One challenge for people without diabetes who may use a CGM is the interpretation of glucose spikes, as they are not well defined.
Despite these concerns, Diana Isaacs argues that the benefits of CGMs for people without diabetes outweigh the risks. For instance, CGMs can provide personalized insights into how diet, exercise, stress, and sleep affect glucose levels, potentially helping with weight loss, athletic performance, and overall lifestyle optimization. Users can customize their habits to support stable energy, improve metabolic health, and recover better from workouts.
Moreover, these devices enable real-time tracking and data sharing via smartphone apps, making glucose trends easily accessible for self-management. For example, Dexcom's Stelo device is marketed to people with Type 2 diabetes who don't take insulin, while Abbott's Lingo is tailored to the wellness market. Dexcom's G7 sensor provides glucose readings every five minutes, while its Stelo app provides them every 15 minutes.
In recent news, the Food and Drug Administration cleared devices made by Dexcom and Abbott for OTC use last year. However, the over-the-counter versions of CGMs do not provide hypoglycemia alerts and display a narrower range of glucose values compared to prescription CGMs. For instance, Abbott's Lingo provides a range of 50 to 200 mg/dL, while its Libre Rio is expected to have a measurement range in line with prescription CGMs.
In conclusion, while over-the-counter glucose sensors can empower non-diabetic individuals to experiment with lifestyle improvements, their scientific backing for use in healthy populations remains limited. Users should be cautious about misinterpretation of data and device limitations discussed at the American Diabetes Association’s sessions.
