Study Summary
A pilot study examined how intermittent scanning continuous glucose monitoring (isCGM) affects adults with type 2 diabetes (T2D) not using insulin. Participants used either a visible CGM (FreeStyle Libre 2) or a blinded one for 12 weeks.
Key Results
- HbA1c: 53% in the isCGM group reduced A1c by ≥5.5 mmol/mol vs. 35% in the control group, but the difference was not statistically significant.
- Time in Range (TIR): isCGM group saw a significant 18% increase (from 30% to 50%), unlike the control group.
- Hypoglycaemia: No episodes occurred in either group.
- Diabetes Distress: Decreased in the isCGM group (from 50% to 25%) but increased in the control group; the difference wasn’t significant.
Clinical Takeaway
Although current guidelines don’t recommend routine glucose monitoring for non-insulin T2D patients, isCGM may improve glucose control and reduce distress. It could also delay the need for insulin.
Future Outlook
Researchers recommend longer studies with lifestyle tracking to better understand how isCGM supports diabetes management.
