Dec. 12, 2023 — Wearable expertise has been a game-changer for customers. From rings and watches to wristbands, patches, and clothes, info that after required a bunch of complicated calculations is now out there anytime, wherever with a flick of the wrist or a look at a smartphone.
Steady glucose screens – gadgets that assist individuals with diabetes keep away from harmful and excessive adjustments in blood sugar ranges – are among the many most up-to-date wearables to seize consideration. Accepted by the FDA to be used in diabetes, hundreds of thousands of customers are leaping on the CGM bandwagon with encouragement from social media influencers and guarantees of improved athletic efficiency, weight reduction, and metabolic well being.
Earlier than you be part of the lots and buy one among these gadgets, know that diabetes consultants are unified of their issues that CGMs usually are not fairly prepared for the patron marketplace for individuals who don’t have diabetes however wish to try to monitor their blood sugar anyway.
“If you happen to look throughout historical past, there’s been many cases the place massive volumes of individuals have adopted one thing that ended up not being right,” mentioned Tamara Oser, MD, director of the first care diabetes lab on the College of Colorado Anschutz Faculty of Drugs in Aurora.
Regardless of their rising reputation, Oser mentioned “we should be aware that we don’t have actually robust proof but that they’re going to trigger a change in outcomes,” she mentioned.
Highs and Lows
Blood sugar spikes after meals are a standard phenomenon.
“They go up, your physique responds inside 15 to half-hour, after which it steadily goes down. That may be a regular course of,” mentioned Marc Kai, MD, an internist at Mercy Medical Heart in Baltimore. “In somebody with diabetes, the quantity might go increased, last more, and take longer to return all the way down to regular; that’s why we use these screens: so we will see what and when it’s occurring.”
The problem comes when an individual who doesn’t have diabetes takes this info and reinterprets it to suit what is usually an incomplete narrative.
“Many firms that promote CGMs and the apps are taking knowledge from their prospects and making generalizations, and that’s simply inappropriate,” says Danielle Omar, a registered dietitian and diet marketing consultant based mostly in Northern Virginia. An instance is consuming oatmeal, which one social media influencer compares to being “chased by a Siberian tiger.”
Some individuals had been seeing knowledge that confirmed their blood sugar spiked after consuming oatmeal. “However that’s simply the best way your physique works; you simply ate a carbohydrate,” she mentioned.
“There’s so many elements,” Omar mentioned. “What was within the oatmeal, what sort of oatmeal was it? “Was it fast oats, metal minimize, or in a single day oats? What was in it? Was it sugar or jelly? A banana? Oat milk? , there are such a lot of issues that may have been the actual cause why their blood sugar spiked.”
Omar’s issues usually are not unfounded. David Lam, MD, an endocrinologist and affiliate professor at Icahn Faculty of Drugs at Mount Sinai in New York Metropolis, mentioned “it’s pure to have a glucose tour. Though CGMs can in all probability inform individuals what their baseline may be and provides constructive reinforcement to scale back caloric consumption, I don’t know in the event that they convey any benefit in comparison with a registered dietitian’s recommendation.”
What CGMs Do and Don’t
Steady glucose screens had been first developed within the Nineteen Nineties to assist sufferers with sort 1 diabetes and at the moment are utilized in sure sort 2 diabetes sufferers as effectively. Researchers are additionally wanting into the advantages for different teams, together with individuals with prediabetes and elite athletes. Nonetheless, these gadgets usually are not with out limitations, nor are they appropriate for everybody.
Lam says that he makes use of the screens in his sufferers with diabetes however not broadly.
“It’s an individualized therapy choice,” he says. “Simply because the expertise exists and is FDA-approved for particular medical circumstances, it doesn’t imply that everybody may be on them. After I prescribe a CGM for my sufferers, it’s at all times with a dialogue about what it could supply, what it does, what its limitations are, and the way I believe it may assist with their care.”
So what particularly do these gadgets do?
“CGMs present an estimation of somebody’s blood glucose in that second,” Lam mentioned, noting that the measurement can assist an individual keep away from harmful and infrequently life-threatening declines in blood sugar, or persistent and equally harmful highs. That is totally different to extra conventional measurements just like the A1c blood check, which measures common blood sugar ranges over a 3-month interval.
In contrast to a finger prick, which measures the sugar focus in blood, “CGMs measure the sugar focus within the tissues simply outdoors the bloodstream – the ‘interstitial’ fluid and state that exists within the tissues,” Kai mentioned. “Primary science dictates that it’s going to be about the identical.”
He mentioned that when somebody has diabetes or insulin points, spikes in blood sugar that usually happen after consuming are inclined to last more and take longer to return to regular. Understanding this info, which known as “time in vary,” can assist form conduct (e.g., avoiding sure desserts) and information remedies or adjustments in eating regimen and life-style.
What You Must Know
There’s little question that there’s in all probability a spot for steady glucose screens within the non-diabetes shopper market within the foreseeable future. Fernando Ovalle, MD, an endocrinologist, professor, and director of the College of Alabama-Birmingham’s Diabetes & Endocrine Medical Analysis Unit, mentioned at the very least a fourth of the inhabitants is in danger for growing diabetes, 20% of whom could also be slowly growing it over their lifetime. “The query is, what number of of these individuals are you able to assist keep away from or delay it, or if not keep away from it, at the very least enhance it?”
Ovalle mentioned extra analysis is required so “we’ll have the ability to know what’s really regular and really irregular past the glucose tolerance check.”
Not less than for now, the expertise wants to enhance. Oser mentioned not solely do readings differ between CGM gadgets, however that they’re much less correct on the decrease versus regular or excessive ranges.
There’s additionally the hazard of “false lows.”
“I’ve a affected person with out diabetes or prediabetes whose CGM flashed a low blood sugar studying. She received so alarmed, she went to the emergency room and it was a false low,” Osler mentioned. Issues like incorrect placement on the physique, dehydration, and even pores and skin trauma the place you place it could additionally affect accuracy.
One other essential consideration is that meals just isn’t the one issue that may influence blood sugar ranges. “Glucose is mostly a window into physiology,” Lam mentioned. “Outdoors of the apparent, train, totally different stressors (together with sickness), hormones that assist our bodies struggle an infection, sleep, medicines, all of this stuff can improve insulin resistance and glucose ranges.”
One of many potential pitfalls of a wholesome particular person utilizing a steady glucose monitor is info overload, Kai mentioned.
“Blood sugar varies from individual to individual, so people are going to lookup numbers and fear when in truth, for his or her physiology, their private physique, their very own private metabolism, the response is completely regular,” he mentioned.
If you’re nonetheless inquisitive about attempting a steady glucose monitor, on the very least, contact your physician or a dietitian who can assist you perceive what the numbers are telling you and how one can harness them in a means that is smart to your private well being.
