Monitoring glucose ranges is having a giant second within the wellness world. Whereas taking common readings of blood sugar was as soon as one thing solely performed by folks with diabetes, the observe has unfold to these looking for potential well being advantages from constantly monitoring their blood sugar.
And as an alternative of doing every day finger pricks to measure glucose within the blood, there’s now an easier and fewer invasive technique to take comparable measurements. You’ve doubtless already seen somebody sporting one with out realizing what it was. It seems to be like a small plastic circle sitting on the pores and skin—often on the arm—generally lined by a bit of sticky material or a round patch.
Meet the continual glucose monitor.
What’s a steady glucose monitor, anyway?
What Is a Steady Glucose Monitor?
A steady glucose monitor (CGM) is a bit of wearable expertise that measures blood sugar ranges as they fluctuate all through the day. These ongoing readings are taken by means of a tiny sensor inserted simply beneath the pores and skin, often positioned on the arm or the stomach. A sticky patch helps maintain the sensor in place.
A CGM has three components:
-
the sensor
-
the transmitter
-
the software program program
The sensor measures the glucose within the interstitial fluid—the fluid between your cells—which correlates with however is just not an identical to the glucose in your blood. As a result of the measurement isn’t taken straight from the bloodstream, it’s thought of an estimate and is much less exact than a finger-prick studying.
Many sensors are disposable and must be changed each couple of weeks.
The transmitter sends the info collected by the sensor to the software program program, usually by way of a smartphone app or insulin pump. The software program tracks the glucose readings, storing and charting the info it receives.
As a result of readings are taken each 5 minutes, you get a normal image of how your glucose responds to what you eat and drink, how you progress, your medicines, and your stress ranges. Over time, the continual readings might reveal patterns that might information way of life or health-related decisions.
What Glucose Monitoring Apps Inform You
Relying on the kind of app used to chart glucose readings, you will get all kinds of data. Many (however not all) let you log meals, snacks, bodily exercise, and sleep.
Whereas the essential perform is to trace glucose fluctuations and set a goal vary, some apps take issues additional. They might:
-
Counsel which meals or behaviors trigger spikes
-
Supply suggestions for adjusting meals or train
-
Present insights geared toward holding glucose in a perceived “superb” vary
-
Supply in-app “licensed glucose specialists” or one-on-one dietitian consultations
-
Embrace packages for weight reduction or diabetes prevention
-
Push personalised teaching, meal guides, or way of life challenges
In truth, many corporations that promote CGMs or supply their very own glucose-tracking apps focus closely on weight reduction as the first promoting level.
What was as soon as a software for managing diabetes has shortly turn out to be one other technique of hyperfixating on weight reduction within the title of “well being.”
Why Are Non-Diabetics Utilizing CGMs?
Proponents of CGMs counsel that this expertise can assist folks dwell more healthy life. With entry to steady glucose ranges, somebody would possibly alter their consuming habits, try to stop diabetes, or—as some anecdotal claims counsel—even put diabetes into remission.
Understanding how your glucose responds to motion may additionally encourage extra constant bodily exercise.
For athletes, CGMs might supply insights into fueling and coaching for “peak efficiency,” although analysis is proscribed on whether or not this gives extra worth than working with a educated coach or coach.
And naturally, biohackers love CGMs as a result of they provide yet one more metric to trace, optimize, and manipulate in pursuit of “optimum well being.”
The Darker Facet of Steady Glucose Displays
Whereas CGMs might profit some folks with out diabetes, it’s vital to acknowledge the downsides.
It’s straightforward to get sucked into the concept of optimizing your well being, and CGMs encourage precisely that. Whenever you’re always monitoring varied information factors in service of enhancing bodily well being, it may well turn out to be obsessive. As an alternative of listening to your physique and making decisions based mostly on the way you really feel, you begin making choices based mostly on the info.
This hyperfocus can result in disordered consuming habits, equivalent to limiting energy or eliminating complete meals teams to maintain your glucose in a perceived goal vary.

Consultants fear that, for non-diabetics, CGMs may very well pathologize regular physique responses—making folks stress over modifications in blood sugar when that’s precisely what wholesome our bodies are purported to do.
The reality is that most individuals don’t want to trace glucose fluctuations to keep up good well being, particularly since there’s no good proof that on a regular basis blood sugar spikes trigger diabetes. Blood glucose naturally rises and falls all through the day; it’s purported to fluctuate and even spike after consuming higher-carb meals. That’s regular, anticipated physiology—not a pink flag.
And no matter what influencers would possibly declare, deciphering glucose information is one thing a educated medical skilled is way extra certified to do than an uncredentialed wellness persona.
So The place Does That Go away Us?
CGMs are wonderful instruments for folks with diabetes who wish to scale back the variety of finger-prick assessments they carry out—however they’re not a full substitute. Direct blood readings are nonetheless extra dependable than interstitial measurements.
Moreover, as a result of glucose fluctuates naturally, it’s straightforward to misread regular readings as one thing regarding if you happen to’re not educated to know the info.
For those who’re not diabetic, you most likely don’t want to watch your glucose carefully.
You’ll be able to take your well being cues from merely noticing how your physique feels.
-
For those who’re drained: you could want extra sleep or much less stress.
-
For those who’re grouchy within the afternoon: perhaps you want meals.
-
For those who’re low-energy: it could be hydration, hormones, or your workload.
You don’t want an app linked to an costly CGM to let you know this stuff—particularly when the units and their related membership charges could be pricey and are hardly ever lined by insurance coverage.
For those who’re not sure or not feeling nice, it’s all the time clever to seek the advice of an precise knowledgeable—a registered dietitian or medical skilled—who can assist you make knowledgeable dietary or way of life modifications. —Naomi
