Continuous glucose monitoring (CGM) may be a choice for checking blood sugar levels. It tracks your child's blood sugar level throughout the day and night. This can help you and your child make better choices about food, activities, and medicines. It can also find trends that can help your child's health care provider better manage the child's diabetes. Besides giving your child's blood sugar at any moment, CGM also gives you the percentage of time your child's blood sugar has been in the normal range. It also tells you when blood sugar has been too high or too low. This is called time-in-range. For most children the target is 70% and the target range is between 70 and 180 mg/dL.
CGM can help manage both type 1 and type 2 diabetes. Your child's provider may suggest a CGM device if your child is newly diagnosed and needs to take insulin. It's ideal for children who need tight blood sugar control. It also helps children who may not notice symptoms of low blood sugar. Ask your provider if CGM is right for your child.
Several CGM devices are available. They are approved by the FDA with a prescription from a doctor. It includes a sensor, transmitter, and a receiver or monitor. The sensor is a small device placed under the skin. It will measure your child's blood sugar several times a minute. A transmitter sends the information to a receiver. This may be a part of an insulin pump or a separate device.
Your child's blood sugar may still need to be checked a few times a day with a regular glucose meter to check for accuracy. The sensor under the skin needs to be replaced every 7 to 14 days.
