Diabetes Mellites is a chronic lifestyle disease which If not controlled properly will affect kidneys, heart, eyes, nerves as well as blood vessels. Frequent monitoring of blood sugar values, Hba1c as well as investigations to rule out the involvement of other organs such as renal function tests, liver function tests, albuminuria estimation, dilated eye estimation, TMT, leg doppler examination, biothesiometry etc should be done at regular intervals. Continuous glucose monitoring (CGM) is a wonderful investigation especially when the HbA1c is low as it helps to understand about the hypoglycemic episodes if any. CGM also helps us for fine adjustments in medications. We have seen patients where Hba1c shows prediabetes or No diabetes bur CGM picked up frequent high blood sugar values which come in the range of Diabetes. CGM followed by diet and lifestyle adjustments help to prevent progression from prediabetes to Diabetes.
Everyone should be aware that low Hba1c alone doesn't indicate that blood sugars are under control as low value of Hba1c may be due to frequent hypoglycemic episodes. Hence frequent blood glucose monitoring following different food items as well as continuous glucose monitoring is also necessary for better outcomes in patients having diabetes. As fluctuations in blood sugars favor organ damage people suffering from diabetes should make it a point to take food at frequent intervals instead of three main meal pattern
