One kind of wearable tech gaining important consideration within the well being and health group is the continual glucose monitor (CGM). Whereas historically meant for individuals with insulin-dependent diabetes, individuals with out diabetes are beginning to use these units to “hack” their blood sugars.
However is utilizing a CGM if you do not have diabetes price your money and time? The reply may shock you.
What’s a steady glucose monitor?
A CGM is a wearable machine that repeatedly tracks glucose ranges with out the necessity for conventional fingerstick checks. In contrast to the fingerstick technique, which checks blood glucose (aka blood sugar), a CGM checks glucose ranges within the interstitial fluid (the fluid discovered between cells). A tiny sensor inserted beneath the pores and skin measures your glucose ranges, and a wi-fi transmitter sends the outcomes to your cellphone or a wearable machine. Fairly cool, proper?
The sensor in a CGM checks glucose ranges each couple of minutes, whether or not you are resting, exercising, working, or sleeping. Another options you may even see on a CGM embrace:
- An alarm that goes off when your glucose ranges are too low or too excessive
- A system that lets you monitor meals, bodily exercise, and medicines
- The flexibility to obtain your information to a pc or smartphone to see your glucose developments
- Pairing with insulin pumps in order that the pump will robotically regulate insulin dosing to glucose ranges
To make sure your CGM is calibrated appropriately, it is essential to check a drop of blood on a typical glucose meter. The studying must be related on each units.

What are the well being advantages of utilizing a steady glucose monitor in case you’re dwelling with diabetes?
For individuals with kind 1 diabetes (or kind 2 diabetes who require insulin), the data collected from steady blood glucose monitoring is an indispensable a part of their diabetes care plan.
Monitoring glucose ranges offers you details about how a lot insulin your physique wants and when it wants that insulin. This enables for higher blood glucose administration and fewer “glycemic excursions” (i.e., having blood glucose ranges which might be out of your personalised goal). Conserving blood glucose inside an individual’s individualized goal vary might help stop diabetes problems within the short- and long-term and enhance a diabetic particular person’s total well being and high quality of life.
There may be some advantages to utilizing a CGM for individuals identified with prediabetes or with a better danger of growing diabetes attributable to household historical past or different well being elements, says Lauren Kelley-Chew, MD and Head of Scientific Merchandise at Levels. She notes that greater than one in three Americans live with prediabetes, and over 80 p.c of this inhabitants is are unaware that they’ve it. Kelley-Chew explains that insulin resistance can happen for a few years earlier than advancing to prediabetes, and that it is influenced by numerous way of life elements, together with food regimen, train, sleep high quality, and stress ranges.
Utilizing a CGM can provide you a fuller image of your metabolic well being and insulin resistance. That is essential as a result of the sooner an individual understands their metabolic well being, the earlier they will make adjustments to stop or reverse that dysfunction earlier than it develops into kind 2 diabetes.
What are the well being advantages of utilizing a steady glucose monitor when you do not have diabetes?
For individuals with out prediabetes or diabetes, the advantages of utilizing a CGM are much less clear. A examine of 153 individuals who did not have diabetes confirmed that blood sugar levels were normal or nearly normal about 96 percent of the time. Is it price measuring one thing if it is solely out of goal 4 p.c of the time? Many individuals would argue that it is not.
One other very small examine of simply 19 individuals confirmed that people who wore a CGM reported being more motivated to exercise. Whereas it is a constructive impact, sporting a unique health machine would probably present related motivation.
Total, there are at the moment no research in peer-reviewed medical journals demonstrating that utilizing a CGM when you do not have diabetes is useful. It is also essential to notice that sporting a CGM isn’t a benign apply. There are some pitfalls to think about earlier than leaping on the CGM bandwagon.
For individuals with diabetes, CGMs aren’t a enjoyable toy they will select to not use if they do not really feel prefer it. They’re an extremely helpful, disturbingly costly medical machine that many individuals who’ve diabetes cannot even afford to entry.
Pitfalls of utilizing a steady glucose monitor when you do not have diabetes
Whereas it could appear comparatively innocent, sporting a CGM when you do not have diabetes can have some drawbacks. As Melissa Mitri, MS, RD, of Melissa Mitri Diet explains, sporting a CGM might make an individual unnecessarily anxious about their glucose numbers. This might be significantly dangerous to an individual with a historical past of disordered consuming, meals restriction, and even nervousness generally. Diet culture is rampant in our society, and obsessively monitoring our physique and health metrics can definitely feed into that.
The truth is, a examine of 647 first-year college college students examined whether or not sporting technology-based weight-related self-monitoring units was associated with eating disorder behaviors. They discovered that the scholars who wore health expertise have been extra prone to report consuming dysfunction behaviors like fasting, skipping meals, and excessively exercising. Whereas no research have seemed on the results of CGMs on disordered consuming behaviors, they may promote an unhealthy obsession with having glucose ranges inside a really tight goal.
Anya Rosen, MS, RD, LD, IFNCP, CPT and founding father of Birchwell Clinic, additionally notes that misguided diet recommendation might be handed out together with CGMs. Particularly, there could also be an encouragement to limit carbohydrates.
For most individuals (together with individuals with diabetes), extreme carbohydrate restriction is unnecessary, and it can even become extremely unhealthy. Rosen notes that if somebody does select to make use of a CGM, they need to work with a registered dietitian to make sure that they embrace carbohydrates in a manner that’s appropriate with their particular person metabolism.
Except for the potential for growing an obsession with glucose ranges, there are sensible concerns when utilizing a CGM. As Colleen Kiley, RD, a registered dietitian and authorized diabetes care and schooling specialist notes, a possible downside of sporting a CGM when you do not have diabetes is getting lots of low glucose alerts, particularly through the evening.
Kiley explains that sensors will alarm at a glucose studying of 70 mg/dL or decrease. This glucose degree could be regular for an individual who would not have diabetes and is not on any medicines that trigger low blood glucose. The sensor also can alarm in case you put stress on it, reminiscent of once you’re sleeping. These alarms could be loud and disruptive to an individual’s sleep. (Ask any diabetic about sleep loss attributable to their situation, and so they’ll have loads to say on the matter.)
Entry to steady glucose displays is a matter
Along with the potential for growing an obsession with reaching “good” glucose studying, there are potential moral points with individuals with out diabetes utilizing CGMs.
Why is it an moral situation? CGMs are lifesaving expertise that many individuals with diabetes cannot afford. CGM units are sometimes costly and are not at all times lined by insurance coverage. Plus, the sensors must be changed each seven to 10 days, a value that may add up rapidly.
In keeping with the American Diabetes Association, lack of entry to CGMs disproportionately impacts people who have a decrease earnings, are aged, and/or are individuals of shade in comparison with others with diabetes. We additionally know that lower socioeconomic status is associated with an increased risk of type 2 diabetes. In different phrases, the individuals who most want entry to CGMs typically cannot afford them.
Closing ideas
The concept we have to know the trivialities of our organic processes feeds into food regimen tradition. If you dig into the (lack of) analysis, selling CGMs to wholesome individuals looks like attempting to get individuals to fret about one thing they do not must be fearful about to promote them one thing they do not want. It is fear-mongering at its greatest.
For individuals with kind 1 and sort 2 diabetes who rely on CGMs for his or her livelihood, the “development” of utilizing a CGM with out diabetes can really feel like an enormous slap within the face. In spite of everything, for individuals with diabetes, CGMs aren’t a enjoyable toy they will select to not use if they do not really feel prefer it. They’re an extremely helpful, disturbingly costly medical machine that many individuals who’ve diabetes cannot even afford to entry.
When you’ve got a household historical past of diabetes or have been identified with prediabetes, a CGM is usually a helpful device to assist stop the event of diabetes. However for the common, wholesome particular person, there’s little proof that utilizing a CGM has any well being advantages. CGMs are simply the newest in well being fads, and till we be taught extra about how they work in wholesome individuals, they’re probably not price your time or cash.
