Continuous Glucose Monitoring (CGM)

When I was on the Insulin Pump I asked about getting Continuous Glucose Monitoring (CGM). CGM allows you to know your blood sugar all through the day without finger pricks. You insert a pod onto your body and it measures your blood glucose continually. You can then see graphs of your blood glucose at all hours of the day/night and log the data. At that time I was told that I was not qualified for CGM because my control was too good.

The idea behind CGM is that if you have feedback and alerts for highs/lows you can treat them effectively. Treatment of highs is via administration of Insulin and treatment of lows is via administration of glucose.

Now there’s a study sponsored by Dexcom (one of the CGM manufacturers) which shows that patients who use CGM get improved blood sugar controls (Ann Intern Med. 2017;167(6):365-374. Continuous Glucose Monitoring Versus Usual Care in Patients With Type 2 Diabetes Receiving Multiple Daily Insulin Injections: A Randomized Trial. Roy W. Beck, MD, PhD, et.al.). The study showed:

Mean HbA1c levels decreased to 7.7% in the CGM group and 8.0% in the control group at 24 weeks (adjusted difference in mean change, −0.3% [95% CI, −0.5% to 0.0%]; P = 0.022).

That doesn’t seem like all that big of an improvement to me. Certainly, the people with CGM did not have good control by any standard. I want to know why the control group got a 0.5% drop.

Any low carb diet is much more effective than that treatment.
