No evidence that continuous glucose monitors improve health in people without diabetes
Continuous glucose monitors (CGMs) were originally developed for people with type 1 diabetes and are now widely used by many people with type 2 diabetes. In recent years, the technology has become an increasingly popular consumer product, marketed as a way to optimize diet, exercise and overall health.
Continuous glucose monitors (CGMs) were initially created for people with type 1 diabetes and have since gained popularity among those with type 2 diabetes and even as consumer products. However, a new review finds no scientific evidence that CGMs improve health or prevent disease in people without diabetes. While CGMs can help adjust treatment and reduce the need for frequent fingerstick tests, particularly for those at high risk of low blood sugar, their benefits are not evident in people without diabetes.
Minna Johansson, an associate professor and general practitioner, warns that normal fluctuations in blood glucose can lead to overinterpretation, potentially resulting in unhealthy dietary restrictions or anxiety. Researchers urge medical technology companies to be more transparent about the lack of evidence supporting CGM benefits in people without diabetes, as it may divert resources from patients with greater healthcare needs.
