Think continuous glucose monitors (CGMs) are only for people taking insulin? Think again.
A new study published in the New England Journal of Medicine examined CGM use in adults with type 2 diabetes who weren't taking insulin. The results were impressive: the CGM group saw their average A1C drop from 8.8% to 7.2% in 26 weeks, compared with a drop from 8.7% to 8.0% with usual care.
So, how does a CGM help? By showing you how your blood sugar responds to meals, activity, and everyday habits—in real time. 📊
In this video, Dr. Ergin breaks down the study, its limitations, who might benefit from wearing a CGM, and how to use glucose data to make more informed decisions about your health.

Dr. Ahmet Ergin discusses a new study from the New England Journal of Medicine showing that Continuous Glucose Monitors (CGMs) significantly lower A1C levels for type 2 diabetics not on insulin. By providing real-time visual feedback on how food and activity affect blood sugar, CGMs empower patients to make immediate, effective lifestyle adjustments.
Okay, so I have been saying this for years
and now the New England Journal of Medicine
basically backed me up, which I'm not gonna lie, feels pretty good.
I am Dr. Ahmet Ergin. I am an
endocrinologist at the Diabetes, Thyroid,
and Hormone Center of the Treasure Coast in Port St.
Lucie and this channel is SugarMD.
Today, should you wear a glucose monitor, a CGM, if you have
type 2 diabetes and you're not on insulin?
Because a brand new study basically just came out on
exactly that for years the thinking was that CGMs
are for insulin users initially you start with
type 1 diabetes and then type 2 diabetes on insulin
because you need to dose right now how
about everybody else well keep pricking
your finger once in a while or when you remember
whatever so no matter what the doctor says patients
do whatever they want anyway most people
just don't remember so let's be honest now
this new trial is called CONNECT published October 14th
in the New England Journal of Medicine.
Adults with type 2 diabetes, not on insulin,
treated in regular primary care offices,
not even endocrinology offices.
22 practices across the U.S.
Half got Dexcom G7 CGM, half got Usual Care,
which is finger sticks.
56 weeks.
And the results?
Well, okay, let me get this right.
The CGM group, their A1C, dropped from 8.8 down to 7.2.
that is 1.6 points now the usual care group
who were instructed to check their blood sugar more
often went from 8.7 to 8 so they improved too
but much less so 1.6 point versus 0.7 point in A1C
reduction which by the way when you put somebody on a study
and tell them to pay attention they're
gonna do better right so they both paid attention
but CGM group did more than twice as good as the
finger stick group time in range
and that's the time that your sugar basically sits between 70
and 180 that time in range is the golden number for you
so it went up about five hours a day five
hours that's a whole work day of better glucose now i have
to be honest with you because um that's
a deal right uh on this channel Dexcom funded
the study now obviously they make the device that
doesn't make the results wrong i'm
a principal investigator in some of the studies you cannot
just tilt a study easily because it is regulated by multiple boards
and multiple places. Now it
was only six months and the people
who benefited most were the ones who started with the highest
A1c. Now if your A1c is already 6.5,
you're probably not going to see a 1.6 point drop
because you don't have much room. But why does this work?
I don't think it's magic. It's just
feedback. Somebody gives you feedback, you're likely to do better.
Now you eat a big bowl of
pasta, right? And you watch the line shoot up like a rocket.
You look at the CGM and you go,
uh-oh, no, that's not good. At this point,
I don't need to lecture you that what you just ate was not
good for you. Seeing is believing, right?
Now that graph literally lectures you. It's way more
convincing than I am.
But trust me, my patients ignore me all the time. I'm used to it. Then
you start experimenting. You take a 10-minute walk after dinner.
You, not me, you take the walk. I
told my wife today look i tell my patients to take
the walk let's take the walk believe me i'm doing
it now when they did that the spike is smaller you eat the protein
and vegetables first right and the
carbs last then you'll have a much smaller spike now you swap
the white rice for i don't know what
cauliflower rice okay maybe not everyone's doing
that but you get it it turns diet advice into
something that you can actually see
so who should consider one if you have type 2 and you're not on
on insulin and your A1C is above target.
Honestly, I think a CGM is definitely worth talking about,
especially if you feel stuck,
especially if you don't really know which foods hit you the hardest.
Because on YouTube, you're going to see one doctor saying that,
oh, well, this fruit will be okay for
diabetes. The other doctor will say, don't ever touch it.
None of these is going to be true for
every individual patient. Now,
I have patients who like spike on oatmeal and then they just do fine
weirdly with pizza. Not a recommendation, just saying.
What about the cost? Medicare is
still deciding about covering cgms
for type 2 without insulin some commercial plans covered
them right and there are over-the-counter cgms now
no prescription needed so you can wear one
for a couple weeks and learn your patterns um take a break
and repeat here's where i will put
in a plug because it fits once you see
your post-meal spikes that's exactly the kind of
glucose problem that our sugar md super berberine
are designed to help with super berberine is the
dehydroberberine and concentrated Ceylon cinnamon.
Dehydroberberine is much better than regular
berberine, and it works through your AMP kinase,
which is the same energy-sensing pathway that
metformin works on, but in a more natural way.
The big meta-analysis of 37 trials found that
berberine lowered A1c by about 0.6 points on average.
Not a miracle. It's not an insulin,
but it's a real reduction.
And with a CGM, you can actually see whether it's helping you. But
lifestyle first, walk after meals, protein first,
sleep, then supplements, then medications if you
need them. If you're in the Treasure Coast area
in Port St. Lucie, Stuart, Vero Beach,
we have a new office in Vero Beach. So please come see us.
Bring your CGM and we'll actually
help you understand your data better.
You can call us at 772-398-7814 or book at tcendo.com
and sugarmds.com for all of your supplement needs.
And if cost is the thing stopping you,
ask about our membership we have one flat monthly
