Continuous Glucose Monitoring May Offer Long-Term Kidney Benefits for Type 2 Diabetes Patients

A recent study published in JAMA Network Open suggests that sustained real-time continuous glucose monitoring (rtCGM) may be associated with long-term improvements in glycemic control and kidney health markers in high-risk adults with type 2 diabetes. While previous randomized clinical trials have shown short-term benefits of CGM in glycemic control, evidence for sustained advantages has been limited. The research, funded in part by a CGM manufacturer, highlights the potential for CGM to protect kidney health by helping manage chronically elevated blood glucose levels, which can damage kidneys over time. Further long-term randomized controlled trials are needed to confirm these sustained benefits and determine if rtCGM can preserve kidney function or delay the progression of diabetic kidney disease.
