Low blood sugar (also known as hypoglycemia) is when your blood sugar levels fall low enough, usually less than 70 mg/dL, that you need to take action to bring them back to your target range. Each person's reaction to hypoglycemia is different.
As unpleasant as they may be, these symptoms are useful as they help let you know that action is needed to correct a low blood sugar.
But many people can have blood sugar readings below 70 mg/dL and feel no symptoms. This is called hypoglycemia unawareness.
People with hypoglycemia unawareness are not able to tell when their blood sugar goes too low and may need help from someone else to treat it – this is also known as a severe low.
They are also less likely to wake up from an overnight low.
If you or someone you know has hypoglycemia unawareness, it is important to check blood sugar frequently or wear a continuous glucose monitor (CGM). This is important for critical tasks such as driving.
A CGM can sound an alarm when blood sugar levels are low or start to fall quickly. This can be a big help for people with hypoglycemia unawareness.
The only CGM that can alert up to an hour before a high or low so that people with diabetes can get ahead of their lows.2,3,4,*

Important Safety Information: Guardian™ Connect CGM System
The Guardian™ Connect system requires a prescription and is indicated for continuous or periodic monitoring of glucose levels in the interstitial fluid under the skin, in patients (14 to 75 years of age) with diabetes mellitus. The system is intended to complement, not replace, information obtained from standard blood glucose monitoring devices, and is not recommended for people who are unwilling or unable to perform a minimum of two meter blood glucose tests per day, or for people who are unable or unwilling to maintain contact with their healthcare professional. The system requires a functioning mobile electronic device with correct settings. If the mobile device is not set up or used correctly, you may not receive sensor glucose information or alerts. For complete details of the system and its components, including warnings, contraindications, and precautions, please consult the user guide at http://www.medtronicdiabetes.com/support/download-library/user-guides and important safety information.
