People who have diabetes can choose from several methods to monitor their blood glucose levels. Many individuals with diabetes appreciate the real-time information provided by a continuous glucose monitor, or CGM since you can see almost immediately how the food you eat affects your blood sugar. CGM also eliminates uncomfortable finger-sticks and improves the ability to control hyperglycemia and hypoglycemia before health complications arise. Explore the research about CGM to determine whether this tool is right for you or a family member who has type 1 diabetes.
