CGMs Benefit People with Type 1 Diabetes Who Already Have Good Control
People with type 1 diabetes who have already been successful in achieving recommended blood sugar goals can further benefit from using continuous glucose monitoring (CGM) devices, according to results of a major multi-center clinical trial by the Juvenile Diabetes Research Foundation. Findings of the study were published online by the journal Diabetes Care, available at http://care.diabetesjournals.org/content/early/recent.
According to the JDRF study, using CGM devices enables people who have achieved excellent control (with HbA1c levels below 7 percent) to continue to tightly manage their diabetes while cutting down on the frequency of low blood sugars, called hypoglycemia. Research has shown that good blood sugar control is a key factor in reducing the risk of the devastating long-term complications of type 1 diabetes, such as blindness and kidney disease — but that the fear of low blood sugar emergencies often prevents many people from achieving tight control, and remains a constant concern for those who manage their type 1 diabetes well. The landmark Diabetes Control and Complications Trial (DCCT) showed that with intensive insulin therapy, excellent blood glucose control was obtained, but at the expense of a considerable increase in hypoglycemia. Today, the JDRF study has shown that, with CGM, hypoglycemia can be reduced while maintaining excellent blood sugar control.
