Preventing Type 2 Diabetes Using Continuous Glucose Monitoring and A Smartphone APP
Prediabetes is a
condition where blood sugar levels are higher than
normal, but not high enough to be diagnosed as
diabetes. It affects about one
in three adults in the US, and increases the
risk of developing type 2 diabetes, heart disease,
and stroke. However, prediabetes can be reversed or
slowed with lifestyle changes, such as eating
healthy, exercising, and losing weight, thereby,
delaying or preventing type 2 diabetes. And
continuous glucose monitoring might prove to be
helpful in the prevention of type 2 diabetes for
some with prediabetes.
The CDC National Diabetes Prevention Program was
established to enable individuals with prediabetes
or a high risk of developing type 2 diabetes to
prevent or delay the disease. The program uses
intensive lifestyle intervention. And continuous
glucose monitoring (CGM) might help people maintain
their intensive lifestyle.
CGM is a system that uses a small sensor inserted
under the skin to measure blood sugar levels every
few minutes, and sends the data to a receiver or a
smartphone app. The app can display the current
blood sugar level, as well as the trends, patterns,
and alerts. CGM
can provide more information and feedback than
finger prick testing, and can help people with
prediabetes understand how their food, activity, and
sleep affect their blood sugar.
A recent
study found that CGM can also diagnose
prediabetes earlier than a blood sugar test, and
might motivate people to make lifestyle changes
sooner. Another
study showed that using CGM and a mobile app
that integrates food logging and physical activity
can improve blood sugar regulation in people with
prediabetes and type 2 diabetes.
More research is needed to determine if CGM and a
smartphone app, for example, can be a useful tool
for treating prediabetes, and thus preventing type 2
diabetes, for the long term. And do so cost
effectively. However, CGM may have a future in
diabetes prevention.
