A continuous glucose monitor (CGM) has two parts. You wear one part—the sensor—against your skin. It has a tiny needle that stays under your skin and constantly reads your blood sugar level. It sends this information to a wireless receiver. The receiver can tell you if your blood sugar is going up or down—and how fast. And you can view the stored data on a computer to help you identify trends in your blood sugar level.
CGMs communicate with some blood glucose meters and even insulin pump systems. All CGMs need to be calibrated regularly with a blood glucose meter to be sure the readings are accurate.

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.
People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.
Congratulations on taking steps to manage your health.
However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.
Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
