Structured Blood Glucose Monitoring (BGM) vs. Continuous Glucose Monitoring (CGM) – What Leads to Improved Glucose Control?

In a study to evaluate the effective means of glucose monitoring, 114 adult subjects were randomized to either BGM (4 times/day) or CGM (24×7) for 16 weeks, with their diabetes therapies adjusted every 4 weeks. Glucose monitoring led to –


Both BGM and CGM Lead to Improved A1c Control. However, CGM is More Effective in Minimizing Risk of Hypoglycemia.


A1c: Glycated hemoglobin; BGM: Blood glucose monitoring; CGM: Continuous glucose monitoring;
