Are Blood Sugar Monitors Worth It for Non-Diabetics and Athletes?

Continuous glucose monitors (CGMs), small devices that track blood sugar levels, are now approved for use by people without diabetes, sparking debate about their benefits. While they have revolutionized diabetes care and can help some individuals identify carbohydrate sensitivities or motivate healthier eating, evidence on their effectiveness for the general population is mixed. Experts warn that data can be confusing, inaccurate, or misleading, and emphasize the importance of proper interpretation and context. Overall, CGMs may be helpful for specific individuals but are not universally proven to improve health outcomes for those without diabetes.
