Glucose Monitoring Devices May Improve Diabetes Management Beyond Insulin Users

Continuous glucose monitors use a wearable sensor to track glucose levels throughout the day. The readings can show how food, physical activity, sleep and medication relate to glucose changes, giving patients and clinicians a more complete picture than occasional measurements alone. In the reported trial, 283 adults with type 2 diabetes who were not using insulin received continuous glucose monitoring or routine care. The monitoring group showed a larger reduction in average HbA1c, a measure of blood-glucose control over time, and spent more time within the study's target glucose range. These findings suggest that monitoring may be useful for some people even before insulin treatment becomes necessary. However, the study's industry sponsorship should be considered, and the cost, accessibility and suitability of monitoring devices differ among patients. A glucose monitor does not replace prescribed medicines, healthy eating, physical activity or regular clinical review. Patients should discuss whether continuous monitoring would be useful for their individual care plan.
