Study Questions Usefulness of CGMs for Non-Diabetics

Popular among health-conscious non-diabetics, CGMs may not provide the same benefits as for people with diabetes. A new study suggests they may not accurately measure long-term blood sugar control.

Study Questions Usefulness of CGMs for Non-Diabetics

A recent study casts doubt on the usefulness of continuous glucose monitors (CGMs) for individuals without diabetes. The research suggests that these devices may not accurately assess long-term blood sugar control or match gold standard blood tests for this group.

CGMs, small wearable devices tracking blood sugar levels, have gained popularity among non-diabetic health-conscious individuals. However, a study found that data from these devices did not align with HbA1c measurements in people without diabetes. The study suggests that CGMs may capture normal short-term fluctuations in blood sugar, which do not impact HbA1c levels. Originally designed for people with diabetes, CGMs may not provide the same benefits for those without the condition. In contrast, for people with diabetes, CGM data closely matched HbA1c measurements, particularly for average glucose levels.

The study highlights potential limitations of CGMs for people without diabetes. While these devices may not accurately assess long-term blood sugar control or match gold standard blood tests for this group, they remain valuable tools for people with diabetes. Further research is needed to determine the most effective use of CGMs for non-diabetic individuals.
