What is Continuous Glucose Monitoring?

Continuous glucose monitoring (CGM) is a process that allows you to track your glucose continuously throughout the day and night, notifying you of highs and lows so you can take action. The Dexcom G5 Mobile Continuous Glucose Monitoring (CGM) System is FDA-approved to help minimize the guesswork that comes from making decisions based solely on a number from a blood glucose meter reading, for better diabetes management.*

The Benefits of CGM

Unlike a blood glucose meter (BGM), which provides just a single glucose reading, CGM systems provide real-time, dynamic glucose information every five minutes — up to 288 readings in a 24-hour period. You can gain valuable insight about your glucose levels, speed, and direction giving you additional insight to proactively manage your diabetes. 

A1C Continuous Glucose Monitoring

A1C Reduction

CGM has proven to be the best outpatient glycemic management system for reducing A1C. Type 1 diabetics experience an average A1C reduction of 1.3%.**1 

Reduced Hypoglycemia CGM

Reduced Hypoglycemia

Not only can CGM use reduce A1C, numerous studies have shown it can also decrease time spent in hypoglycemia.1-3

Active monitoring at night CGM

Active Monitoring at Night

CGM systems are equipped with alerts that warn you of approaching lows and highs. 

Discover Dexcom CGM

The Dexcom G5 Mobile CGM System consists of three parts:

 

  1. a small sensor that measures glucose levels just underneath the skin
  2. a transmitter that fits onto the sensor and sends data wirelessly to your display device
  3. a small receiver or compatible smart device4 that displays real-time glucose information

 

The Dexcom G5 Mobile CGM also provides customizable alerts to warn the wearer of approaching glucose highs and lows. Studies have shown that CGM may help reduce your A1C and reduce your risk for hypoglycemia, whether you are on insulin injections or pump therapy.2

BRIEF SAFETY STATEMENT The Dexcom G5 Mobile Continuous Glucose Monitoring (CGM) System ("G5") is a glucose monitoring system indicated for the management of diabetes in persons age 2 years and older. The G5 is designed to replace fingerstick blood glucose testing for diabetes treatment decisions. The G5 also aids in the detection of episodes of hyperglycemia and hypoglycemia. The G5 is intended for single patient use and requires a prescription. CONTRAINDICATIONS Do not rely on the G5 CGM data if you have recently taken acetaminophen. Remove the G5 (sensor, transmitter, and receiver) before Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scan, or high-frequency electrical heat (diathermy) treatment. The G5 is MR Unsafe. Do not bring any portion of the G5 into the MRI environment. WARNING CGM-based diabetes treatment decisions are only approved with the G5, not previous generations of Dexcom CGM systems. Calibrate at least once every 12 hours using a fingerstick. If your G5 does not display a sensor glucose reading and an arrow, or if you are getting inaccurate or inconsistent readings, take a fingerstick. If your glucose readings and alerts do not match your symptoms or expectations, take a fingerstick to confirm. Failure to do so may lead to hyperglycemia or hypoglycemia. The G5 is not approved for use in pregnant women, persons on dialysis or critically ill persons. If a sensor breaks and no portion of it is visible above the skin, do not attempt to remove it. Seek professional medical help if you have infection or inflammation on or near the sensor insertion point. Report broken sensors to Dexcom Technical Support. Sensor placement is not approved for sites other than under the skin of the belly (ages 2 years and older) or upper buttocks (ages 2-17 years). To “share” data, you need an internet connection and a separate compatible smart device running the Dexcom Follow App. Contact Dexcom Toll Free at 877-339-2664 or www.dexcom.com for detailed indications for use and safety information.
