CGM has the potential to diagnose glucose abnormalities earlier than OGTT.Aim:To compare CGM vs standard OGTT in determining diabetes and other glucose abnormalities.Methods: 44 CF patients underwent OGTT followed by CGM for three days.The patients were classified according to OGTT categories and the CGM results.CGM results were grouped as hypoglycemia, hyperglycemia and both hypo and hyperglycemia.View this table:OGTT and CGM resultsResults: In 26 patients who had normal OGTT, CGM showed hyperglycemia in 7, both hypo-and hyperglycemia in 6, and hypoglycemia only in 1 patient. The frequency of hypoglycemia in OGTT was %13.6.Conclusion:CGM is a useful tool especially to determine hypoglycemia in CF patients which might be missed by OGTT. We suggest that CF patients should be evaluated by CGM especially if they are to be started/or on insulin treatment to detect and prevent hypoglycemia appropriately.
