Why Continuous Glucose Monitoring (CGM)?
CGM — the new standard
CGM has gained acceptance among diabetes experts as an effective tool for helping
people achieve their diabetes goals
1:
- Achieve A1c targets without adding hypoglycemia2-4
- Reduce glucose highs and lows2-4
- Reduce hypoglycemia2-4
Between The Lines™ — Improving diabetes management
Over a decade ago, a landmark study called the Diabetes Control and Complications
Trial — the largest study of its kind — revealed the importance of good
glucose control. New, large-scale studies are revealing even more improvements in
glucose control with the use of CGM technology.2 In a recent study, people
who were considered to be in "good control" showed distinct improvements in time
spent within their target zone while using a DexCom CGM device.5 And
subjects who were considered to be in "poor control" before the study, had even
more impressive improvements with a 70% increase in time they spent in their target
zone.5
A recent study by the Juvenile Diabetes Research Foundation showed that using a
CGM, such as the SEVEN® PLUS, for at least 6 days a week can lead
to significant decreases in A1c and can provide a greater ability to reach the ADA
recommended goal of 7%.2
Revealing unnoticed highs and lows
A CGM device can call attention to highs and lows that you may often experience,
but not recognize.3-7 Sometimes people have "hypoglycemia unawareness"
— they no longer feel their symptoms of going low. And some people are also
unable to feel symptoms of high glucose. Over time, frequently swerving outside
of your target range can lead to severe consequences, such as damage to your nerves,
eyes, kidneys, and other organs.8,9
CGM vs. A1c and fingersticks
A1c tests taken by your doctor have long been considered the gold standard for a
test of glucose control. However, because A1c is an average of glucose levels over
time, a person can have major highs and lows every day, yet still have a "good"
A1c level. This is one reason why recent clinical trials reveal that A1c tests alone
do not necessarily correlate to good diabetic control.7 It is also important
to know that the more often you are outside your target range, the higher your risk
of diabetes-related complications.8,9
Recent studies reveal that fingerstick testing alone does not provide enough information
to stay within their target range — even people who monitor frequently.2-6
In contrast, the use of a CGM device does a better job of helping people to
