Continuous Glucose Monitoring (CGM) involves wearing a small glucose sensor inserted in the subcutaneous (fatty tissue) layer under the skin, usually in the abdomen or upper, outer flank/ buttock. The sensor measures glucose every 5 minutes and is normally worn for a 6 day period. Once complete, the data is uploaded and plotted onto graphs, enabling identification of glucose patterns. Do I need CGM? CGM may be recommended by your doctor if you are experiencing fluctuations or concerning trends in your blood glucose levels, especially overnight. CGM can be offered to people using insulin pumps as well as to those on multiple daily injections, including people with type 1 or type 2 diabetes. CGM can be a very valuable tool for both you and your diabetes team to see a big picture of what is happening with your diabetes. CGM can shed light on factors that influence your glucose levels to guide day-to-day decisions and adjustments in your management.
