To manage your diabetes, you'll learn to monitor your glucose levels or the amount of sugar in your blood. You'll use the results of monitoring to make daily decisions about food, physical activity, and medication.
Blood glucose meter
The most common way to check glucose levels involves pricking a fingertip with an automatic lancing device to obtain a blood sample and then using a glucose meter to measure the blood sample's glucose level. Many types of glucose meters are available, and all are accurate and reliable if used properly.
Continuous glucose monitoring
Continuous glucose monitoring systems use a tiny sensor inserted under the skin to check glucose levels in tissue fluid. The sensor stays in place for several days to a week and then must be replaced. A transmitter sends information about glucose levels via radio waves to a wireless monitor that you wear.
