A CGM is a device worn on your abdomen or arm that has a sensor that checks your interstitial fluid every five minutes. CGMs worn on the outside of your body are changed every 7-14 days, depending on the brand. DMS also offers CGMs that are implanted under the the skin which may be worn for 90 days. The device generates 288 blood sugar readings a day. You may need to check your blood sugar with finger sticks with some brands. CGMs provide valuable information for people who have wide swings in their blood gluclose or who have A1c values (see below) that don’t match their blood glucose meter readings. Understanding where your blood glucose is trending will help eliminate extreme highs and lows with your levels.
