Impaired awareness of hypoglycaemia: Prevalence and associated factors before and after FreeStyle Libre use in the Association of British Clinical Diabetologists audit.

Abstract

FreeStyle Libre (FSL), intermittently scanned continuous glucose monitor ing (isCGM), is associated with less biochemical hypoglycaemia in people with diabetes, lower HbA1c and diabetes-related distress.1 Impaired awareness of hypoglycaemia (IAH), which affects 18%-33% of people with type 1 diabetes,2 is the reduced ability to detect the symptoms of hypogly caemia and is associated with a 6-fold increased risk of severe hypoglycae mia (SH).3 Many of the studies of CGM have shown a reduction in rates of hypoglycaemia but have not shown restoration of awareness.4-6.
