Continuous Glucose Monitors May Help Type 2 Diabetes Patients Who Do Not Use Insulin

Continuous glucose monitors measure glucose levels throughout the day using a small sensor worn on the body. Rather than relying only on occasional finger-prick measurements, users and healthcare professionals can view glucose trends, identify rises after meals and detect patterns that may be missed by infrequent testing. In the reported six-month trial, 283 adults with type 2 diabetes who were not using insulin received either CGM support or routine care. Average HbA1c—a measure of blood-glucose control over time—fell from 8.8% to 7.2% in the monitoring group, compared with a fall from 8.7% to 8.0% in the routine-care group. Researchers also reported that CGM users spent around five additional hours per day within the study's target glucose range of 70–180 mg/dL. These results suggest that glucose monitoring may help some people understand how meals, activity and medicines affect their glucose levels, even before insulin is required. However, the trial's sponsorship should be considered when interpreting the findings, and cost, access, comfort and individual clinical needs remain relevant. CGM devices do not replace medical follow-up, prescribed medication or professional guidance. Patients should discuss whether a monitor is suitable for them with their diabetes-care team.
