Continuous glucose monitoring (CGM) is a way to check glucose levels throughout the day and night without pricking your finger. CGM can help you see the effects of insulin and other medicines, food, physical activity, and illness on your glucose levels. It can help you make decisions to keep your glucose levels in a healthy range. It can also help find trends or changes in your glucose levels. You can use this information to make day-to-day decisions about how to manage your diabetes. You can also share this information with your diabetes health professionals to help make decisions about your diabetes management. CGM provides more information than blood glucose monitoring with a finger prick check. Read more in our fact sheet.
