Effects of Continuous Glucose Monitoring Discontinuation in Adults With Type 2 Diabetes Not Using Insulin
Authors' conclusion
In noninsulin-using people with T2D, glycemic measures improved with real-time CGM use, but these improvements deteriorated substantially and significantly when CGM use was discontinued. More research and more sensitive behavioral assessments are needed to better understand which factors and behavior changes may account for the glycemic decline.
Study context
- Population
- Noninsulin-using adults with T2D
- Comparison
- Continuous glucose monitoring (CGM) discontinuation vs Phase 1 Post-intervention period
- Outcome
- Percent TIR 70 to 180 mg/dL
- Follow-up
- After 4 months of CGM discontinuation
Methodological detailsblinded CGM, before-after comparison
- Blinded CGM
- Before-after comparison
Main finding

95% CI −22% to −12%; P < 0.0001
Further findings
Additional glycemic metrics
- Several additional glycemic metrics worsened significantly from Post to Follow-up
- P < 0.05
Dietary intake and exercise
- Not statistically different at Follow-up vs Post
- P > 0.05
Physical activity
- Physical activity decreased at Follow-up vs Post
- P = 0.01
