A person with type 2 diabetes can use a CGM at their discretion. Since a CGM can measure the bodily blood sugar levels every 3 minutes and will represent the data graphically, it would be an added advantage to look for any patterns or ups and downs during a certain part of the day. For example, if the morning sugars are high, the night-time insulin dose/medication can be upped. CGM can also help understand how the body interacts with certain foods. So in case you realize that eating a banana increases your sugar levels, you can choose to eat it only during lows, or bolus appropriately for it. This device, therefore, helps in planning the diet as well which is an important part of diabetes management.
