The truth about glucose monitors (CGMs) for non-diabetics

[@warthog733]

This past year I was diagnosed as "pre-diabetic". I browbeat my primary care provider into a prescription for a CGM. It has been one of the most valuable tools in my toolkit to get my blood sugar down. I am now officially no longer "pre-diabetic". I still have more to go as my average glucose is 94, and I want to get it down to the mid-80's. The FDA is making a huge mistake by restricting prescriptions to "full diabetics". Why wait until the physiological damage is done?? A CGM and recommendation for keto or carnivore diet would drastically decrease the cost of health care in the long term.

[@Robinhood179]

It really doesnt make sense. You would think the CGM makers would be pounding the doors down wanting more sales and no doubt they would get them too if it was allowed. Why regular people cant get them is insane. Imagine if only those with high blood pressure could buy a BP Monitor?

[@JoeMama-no2kl]

This was the primary driver for me to get a CGM. My current chemo treatment is driving up my BG readings from day one. I went from a fasting BG of 89 and an A1C of 6.0 in February (not great, but Ok) to my current A1C of 8.9. I had to say something to my PCP every time I saw him and he blew me off. It took saying it to my onco team week after week for them to send a referral to diabetes treatment to get him to send prescription for CGM. I still haven't gotten any other treatment feedlot asking. After my last treatment (1st with CGM) my BG went from 180 to over 500. It stayed over the 350 threshold for almost 12 hrs despite fasting. I am not sure what will kill me first, the cancer or the diabetes. I keep working on getting as close to zero carb as possible and hope that will help both.

I saw your original video on this. A couple weeks later I went with my diabetic, non insulin dependent husband to his doctors visit. The doctor had just finished wearing hers for ten days. She had gotten it as a sample. She gave him a simple monitor to wear for ten days. I do not remember him doing a 12 hour wait to set the monitor. Anyway it was very helpful for him. He got to see how much snacks spiked his sugar, also ice cream. He has cut out snacks but still eats ice cream. I can only do so much to support his diet. 🤷🏼‍♀️

@Sufficient4UsIsAllah well, I grew up in a family of alcoholics. Most of them got sober along the way. Being a Child of Alcoholics is also a thing and in fact AlAnon is a group that supports them. AlAnon and Alcoholics Anonymous are based on The 12 Steps to find recovery. 12 Steps talk a lot about consequences for one’s actions and setting boundaries. It’s important to set your own boundaries with the people you care about. That boundary can be to not take someone’s actions personally. Their actions are their own choices. They are adults and they don’t usually make choices to hurt others. Don’t let their choices hurt you. That’s your choice. AlAnon is a great place to learn about this. The meetings, both virtual and in person are no charge. They are also nice and understand if you say, I don’t feel comfortable talking right now. One more point, not all alcoholics drink alcohol. They are called dry drunks and are often in more denial than the “wet” ones. By your question I can tell you are a very caring sibling. Take care of yourself too.

It was a proof that Keto works. Perfectly flat sugar levels. Even during stressful situations at work. Every single meal was ok, no sugar spikes and I was not crazy about super expensive organic food. Just regular, wisely chosen products with close to zero or zero carbs.

Great job!

[@scotthanford9619]

Dexcom's Stelo is $100 for 2 devices. It's over the counter so no prescription needed. Each device lasts 15 days. If you aren't diabetic or pre-diabetic, you only need to do this for a couple weeks to gauge which foods and drinks are problematic. For me, it was Cauliflower pizza (100 Grams of carbs), Oat milk lattes (15-30 grams of carbs) often first thing in the morning on an empty stomach, and any alcoholic drink. High intensity activities like playing soccer also spiked but that is normal from what I researched.

I'm an insulin dependent diabetic. I use the Libre 3. I put the next sensor on my other arm 12 hours before my current sensor expires, once it expires, I scan the new sensor. This makes my new sensor already seasoned and my readings have been more accurate. Since March 2024, I've dropped from 58 units of long acting insulin to 36 units. My short acting insulin has dropped too. I've lost 15 lbs. It's been easier because I can see what spikes my levels and adjust. It's a game changer for me! I'm currently 95% in range and my A1C is 5.9... lower than it's been in many years! I've been diabetic for more than 40 years, diagnosed at 16 years old. It took a long time for me to agree to putting "spy wear" on my body, but I don't look at it that way anymore! I talked my brother into using one and he loves it too.

[@blahblah6725]

Thank you for this video. I think anyone should try a Continuous Glucose Monitor at least once. Depending on the brand, one CGM will work for 10 days or for two weeks. Notes: 1. I don't think the sauna raised your blood sugar as much as you think. The CGM is temperature sensitive, and will show a higher meter reading when it gets warmer. This could happen in a sauna or hot shower. I cannot say reliably how much the rise in the meter reading is due to the meter getting warmer, and how much is your body actual metabolic response. One clue, if you take a quick hot shower, then get out of the shower and look at the graph from the CGM, you will see the meter reading spiked very fast when the shower started. Usually the sugar in the interstitial fluid, which is what the CGM measures, takes five or ten minutes to track your blood serum. When you see an instantaneous spike, that's a clue the CGM was affected by heat. 2. People using CGM should understand that it ONLY MEASURES GLUCOSE. Not Fructose. When you eat fruit, it is a mix of glucose and fructose. Fructose is by far more damaging. So if you eat some fruit and see a spike, consider it the tip of the iceberg. The Glucose measurement is the tip of the iceberg. The Fructose, which CGM does not measure, is the seven-eighths of the iceberg submerged which you do not see. Other compounds you will not see on the meter are lactic acid (yogurt, sour cream, sauerkraut), and alcohol of all kinds (wine, whiskey, and "alcohols" such as inositol, sorbitol), and vinegar. This means a high reading on the CGM does mean you ate the wrong kind of food, but a low reading does not mean you avoided foods diabetics should not be using, such as alcohol. 3. Many doctors and patients use CGM not to educate which foods to avoid and how long to fast, but rather to enjoy more of those foods more often and know when to "fix it" with a dose of insulin. This is an abuse of the CGM. The goal should always be to lower insulin by proper diet, not to increase insulin to pander to addiction. This is true even for type 1 diabetics, who must inject insulin, but still should aim to reduce the dosage, not increase the dose to eat more carbs.

[@blahblah6725]

The book "Rethinking Diabetes" by Gary Taubes is a history of how diabetes treatment developed over the past 200 years. It is a bit nerdy so if you just want to know what to eat, keep listening to Dr Boz. Among other things, the book describes the history of glucose monitoring devices and how the how a large part of medical establishment developed the attitude that diabetics should eat "normally" (that is about 50 percent carbs) and use insulin injections to raise their insulin to deal with the carb overload. A tragic story, when you consider the suffering that millions of people had to endure because of complying with incorrect advice from their doctor.

[@dameanvil]

00:00 🩺 Continuous glucose monitors (CGMs) are typically FDA-approved for diabetics who inject insulin; non-diabetics might need a prescription for self-study purposes. 00:42 💸 CGMs can be costly, around $200/month excluding additional expenses for test strips, glucose meter, or doctor's visits for the prescription. 01:09 ⏰ Monitoring blood sugar can become a time-consuming distraction; spikes might not return to baseline as quickly as expected. 01:36 🧘 Understanding individual blood sugar spikes: Some spikes, like those induced by sauna sessions, might have beneficial effects. 02:16 🍷 Lifestyle habits significantly impact blood sugar; alcohol consumption can affect numbers for days. 02:30 📊 Calibrating CGMs accurately within the first 12 hours is crucial; improper calibration can lead to inaccurate readings and false alerts. 02:59 🚨 Understanding and managing alerts: Not all alerts might be relevant for non-diabetics; learning to disable unnecessary alerts can be crucial for a better experience. 03:25 💡 Despite challenges, CGMs can be valuable for health monitoring and biohacking; accessing a prescription might involve an online process for non-diabetic users.

I got a Stelo (which does not require a prescription). I love having data that is available almost immediately (it updates every 15 minutes). Blood glucose doesn't usually change that much in 15 minutes. I'm so glad that I got it, and I may wait awhile before getting another. I've got a pretty good idea of what works for me now and I'm always within 99% of my target range, even though I'm using the lower range designated for people who have never been diagnosed as diabetic. I like that it gives me feedback, not only on how high it goes, but also on how long it takes me to recover. This shows me the level of my insulin sensitivity. I also now have concrete feedback on the value of walking after a meal, to recover a normal range of glucose. p.s. The Stelo costs $100/mo. or $90 with a subscription.

Mine has been absolutely worthwhile.... I had major issues with hypoglycemia both on a standard diet and ketovore which crash my metabolism. So, I've been using it and I've found reactive hypoglycemia from carbs. The best fix I've found is just increasing my protein intake which keeps me from going low, keeps my metabolism up, and actually helps me lose weight. The only real downsides are that sleeping on the arm it's installed on can cause fake low readings making the low alarm go off and the $150 every 28 days for the libre 3 sensors.

[@jasminjasmin6328]

Dear Dr. Boz, I thank you very much for your videos which are very insightful and valuable. Regarding the Continuous Glucose Monitor I would just like to mention one issue: The CGM constantly emits an electromagnetic field/radiation, as it is regularly connecting with the little machine that indicates the numbers. As I am personally sensitive to certain frequencies, I cannot spend a lot of time around a person with a CGM. And it would not come to my mind to have one attached to my own body. I would be interested about your views on this, especially if it is possible that everybody, whether s/he feels it or not, can be affected by this sort of radiation. I am aware that there are many different frequencies, and that different people react sensitively (or not) to different frequencies. I am personally sensitive to frequencies emitted by mobile phones/antennas/wifi/bluetooth as well as the frequencies emitted by induction cookers.

[@The_New_Abnormal_World_Order]

Hi I don't own one but I looked at the ones for sale here in the UK. You can get ones that don't connect permanently and only give you a reading when you actually scan the sensor with a phone or reader device. I wouldn't want the EMFs either from a device that is permanently emitting.

the spike at the sauna is not your blood sugar spiking. the sensor is affected by the heat and that’s why you are seeing the spike, so fear not. This is according the the manufacturer. One one of his podcasts, Dr Ben Bickman saw this spike on his, and mentioned this to the CGM maker and that was their answer. Cheers.

[@boatman222345]

The part that often gets left out in discussions of CGMs is their lack or real time accuracy. As is also the case with finger prick blood glucose meters these devices are commonly off by as much as 15% or more either high or low. Since you never know whether a particular reading is on the high or low side this leaves you with a window of vulnerability of 30% or more. When I hear folks seemingly confident of point spreads of 10/15 points meaningfully reliable I am caught between laughter and tears. These devices can be useful for insulin dependent diabetics as they titrate their insulin regimens. And if used carefully they can detect the early onset of Type 2 diabetes. But as a tool to be used to rate athletic performance and training protocols they are an expensive tech toy which can actually screw up rather than fine tune your workouts. s

Every gestational diabetic mother should hands-down use a CGM. I recommend the Libre 3 since you don’t need a reader or calibration (it has a “calibration period” if you use it to dose insulin, but doesn’t require any manual work), and if the sensor falls off you can get a free replacement.

You need a CGM, regardless what this lady says. Do not rely on influencers like she is. Learn about your body as much as you can. There's no such thing like 'spending too much time' with it. The more you know the less you'll eat junk food. Sauna reduces my blood glucose levels, not raising it.

I am NOT a diabetic, but I do assist 2 Veterans who are, and both are using the Dexcom system. I do agree you should not be applying the sensor near bedtime. However, based on my observations and several phone calls to Dexcom support in the first 12 hours, you should not be chasing the Dexcom to calibrate. Let it go and stick check about 6 hours and continue 4 to 6 hours later. I guess everybody has their own opinion on this. What I have discovered is if you calibrate early you can almost expect to recalibrate to correct that first one.

I have a freestyle Libre three CGM that I use along with a Freestyle blood test kit that I use for more accuracy. I just purchased the keto mojo kit so I could measure my key tone level. Your video seems to indicate you’re talking about CGM‘s, but you’re using, the keto mojo reader. Will it read like a CGM? If not, which CGM do you use? Thanks.

[@gj9736]

Getting a CGM is fine if you have no issues with an allergic reaction to adhesive and I mean any adhesive. My skin will turn red and raw to the point of blisters and getting bloody if I just wear a bandaid so a CGM is out for me. I am not a diabetic, nor am I a pre diabetic but I been Keto for a while now and would like to monitor my blood sugar range, I am currently using a pretty accurate regular glucose monitor which works fine for me.

[@sunnyco6325]

Why can't they come out with a continuous reader that does glucose and ketones?

[@jt8142]

I find CGMs to be consistently inaccurate compared to blood testing with my FORA glucose & ketone monitor. Whenever the Dexcom G7 or FreeStyle Libre CGMs alert me to too low or to higher blood glucose readings (e.g. 119); I prick my finger and the readings are 10-30 points higher or lower: I don’t understand why this is happening. Is it because I’m pretty lean to begin with (BMI 17.8-18.5)? I’ve also re-calibrated multiple times to no avail.

[@rancid216]

My Stelo (no prescription needed) was still reading 15 to 20 points high after two days. On another channel person that wears a Dexcom G7 said that they get the best readings by placing it on the thigh. So I took off the sensor on my arm and placed the second one on my thigh. Have to see how that works. I contacted Stelo and said I had a defected sensor. So hopefully, they replace the first sensor.

[@Omar-hc3mc]

That's explanation simplify and clarify everything about CGMs. An A for effort

[@flufygrowth]

the sauna thing.... the device is very sensitive to temperature. It goes up every time i take a hot shower. it's not really the bg, it's just the device getting hot.

[@amy11228]

Same experience. I checked my glucose while in the sauna, no spike. Even though I spiked on my CGM. Same thing when I go outside in the cold or into an air conditioned cooler like the produce cooler at Costco. CGM shows glucose is going way low, while finger sticks over the same period show no change in glucose. Same when I exercise. It's pretty annoying that ambient temperature change affects how the device reads your glucose.

[@dannielleselement5940]

I am a T2D NOT taking insulin. My insurance does cover the CGM! I was surprised. Wearing one has been a game changer for me.

[@alaskabarb8089]

Definitely haven’t found anything near that price. I tried to get a Dexxcom6, (having read good reviews for them) to manage pre-diabetic hypoglycemic episodes. Insurance would not cover it because I’m “not a diagnosed diabetic on medication. “ Walgreens called and said, “we want to tell you how much this will cost before we fill the prescription - it’s 1700.00.” “Okay, that’s pricey, but I’ll spring for that monitor/meter.” The pharmacist replied, “No, it will cost about 1700.00 PER MONTH, for the electrode patches - that’s not counting the meter. “ Obviously, prices vary between brands, and maybe the Dexxcom6 is a fancy one, but how can anyone afford it without insurance?

[@carong.3072]

Call around to other pharmacies, check different brands. My freestyle is about 900 for three month supply through CVS. My insurance covered about 8%, they had a coupon for about 190, and my out of pocket was 225. Decimal was a lot higherper sensor and they need to be replaced every ten days. I calculated that the Dexcom would have been at least 10X's the price.

[@DoctorBoz]

There is something wrongs … that is about 10 TIMES higher than what I hear patients are paying

[@michaelvadney5803]

Thanks for the video. I noticed that if I'm doing something fun like e-foiling that my blood sugar levels spike big-time,like 180! Is this unusual or bad for me? It's physically stressful as I am new to the sport, but it just seems odd that it spikes when hadn't eaten anything to bump it.

[@username20213]

I’ve been dealing with blood sugar stuff for a while, but unswt has made it so much easier to figure out what works for me. The AI sugar tracker shows me exactly how different foods affect my levels, and it’s been a game changer. If you’re looking for something easy and helpful, definitely give it a go!

[@penultimatename6677]

Companies like Levels will qualify people without the need to goto your primary doctor. I believe some CGM monitors do not require calibration.

[@garyglynn9945]

I found mine (Freestyle) to be aggravating in that the alarms can't be muted. I always had to remind myself that this was intended for those with T2D. The proximity alarm drove me nuts. I plan to use it again when I'm in a position to deal with the distractions it presents.

Also, the keto mojo reader seems to be a lot less accurate in my freestyle, which I’ve used for years and compared to my test seems to be more accurate. I’ve done a control test on the new keto mojo reader, and it seems to read correctly according to the control test. What can you tell me if anything?

[@doloresseames5067]

I just ordered the new Stelo unit. It’s under $100 for the month, and no prescription required.

You you’ve been keto for years and fasting weekly for years and still insulin resistant. That’s a little discouraging.

[@DoctorBoz]

Well … it is a MILLION times better … but I can still see some things that happen to insulin resistant patients

[@triciaobrien8220]

I have heard that the inexpensive CGM machines can be purchased for about $100 on eBay or at Walmart without a prescription. Is this what others are finding in the USA? I believe Libre is the most inexpensive brand. It is only the sensors that require a doctor's prescription, right?

[@timsmith658]

Love my CGM, now, why can’t big medical invent an CIM, for Insulin? Actually, I know the answer😢

[@karinhart489]

So here it is 7 months since you posted this video. I think within the past week the FDA okayed CGMs for non-diabetics. I’m hoping that means insurance & Medicare will approve a prescription for a CGM (even for just a few months), and that you do a new video when they do.

[@rejak-p2j]

How do we take care of the cgm when showering? Should we remove it when showering and put it back on later after showering?

[@sleazybtd]

Much appreciated. I wanted one to try to time when my pre-workout meal produces a spike so that I can take advantage of it during the workout.

[@Stotz360]

I have type 2 and it’s under control. I got one of these and my insurance pays all but 75.00 for a 90 day prescription.

[@Fahri1945]

Anyone who has a diabetic in their family history and doesn’t want to be a diabetic, needs to get CGM and learn how to eat when to eat how much to eat, only way to live healthy, great tool to learn how your body reacts to different types of foods.

[@icecreamforever]

With more usage even by non-diabetics hopefully it'll bring the price down.

[@dillydanny-o8807]

The type of CGM matters. The Libre 3 is by far superior-no calibration or meter required. It alerts my phone too so I don’t need to wait on a data dump at the end of the day on a separate reader.

[@ocean8866sea]

Were you able to lower your ha1c with keto and intermittent fasting?

[@sunnyside9197]

I am a prediabetic. I used dexcom G7 CGM. On the first two days, the readings went insanely high. I kept double-checking with Contour nexGen Glucometer that persistently showed 1.5 to 2.5 mmols lower readings. I kept observing and on the fourth day realized that the readings were kind of stabilizing in terms of glucose spikes but still showing higher figures. I am now convinced that the prick method is the best despite all the pain and blood. CGM are nothing more than a general idea about your blood sugar patterns and cannot be relied upon. If you have to confirm every suspicious reading on a Glucometer then what is the point using such an expensive method? I'll throw it away after ten days and never use again.

[@DoctorBoz]

I’d pause before throwing it out & not trying again. The first device for me (& many of my patients) is a lot of device learning. I don’t mean PERSON learning … I mean device. The number of calibrations on my first device was not what I expected either … but the second device the data leveled out … and it improved so much by the third device that I literally checked my blood sugar 2-3 times in the whole 10 days. Just my thoughts. I understand the frustration

[@vincentengongoro2705]

My insurance has been covering the libre freestyle 2.. Its not always accurate but it gives a point of reference to operate from.. combined with a finger stick its been a good tool to help me control my type 2

[@jrennickemd]

Very informative video! I am always curious about if you know of any studies that look at glucose excursions in non diabetic patients and any hard outcomes? I haven’t seen much so I always wonder what to make of this data with so much unknown.

[@titaniumsandwedge]

As a pre Type 2 I found my CGM very useful to week out extreme spiky foods. At night, strange things happen to my glucose as I have been alerted several times once with a 36 mg/dl reading. Strange thing is I feel no difference between 37 mg/dl or 456 mg/dl (I had this). Type 1s tell me they notice the difference.

[@OleensEmbroidery]

I pay out of pocket for mine. I had to know. Stress and carbs spiked it for me.

Curious what your thoughts on people with PCOS should try it, if it would be helpful at all. Pcos insulin resistance and blood sugar issues are a struggle. I doubt insurance would cover it for pcos tho.

[@melissal3383]

Love my CGM. I’m 59. Once I hit menopause…. IF I have an evening with carbs or dessert, my blood glucose levels will stay in the 90’s low 100’s during the day for 3-4 days before dropping back to their baseline. I’m thankful that I’ve been checking my numbers sporadically since about 2010. I’d have no clue that they were starting to creep. Everyone, should start checking their BS so you have a base number. Things change & I’ve had to become way more disciplined in my eating habits. Which is good, because it was hard to practice what I heard being preached until REALITY came knocking on my door!

[@jazzmoon77]

Mine seems to show that my blood sugar drops then spikes during my sleep, and could be the cause of my terminal insomnia. I’m not really concerned about spikes after eating, I’m more interested in the overall picture and patterns as my long term A1C tests are always good.

If you have an iPhone and the dexcom g7 app /. Go to “history” (found at the bottom), click on it. Click the “+” sign. Click on Blood Glucose. Do a test with your glucose blood monitor and get a reading. Then in the app click on USE as Calibration. And enter the value and click save. I calibrate about twice and when the monitor readings are stable. You will have a better calibration that way. Hope that helps.
