Dec. 12, 2023 — Wearable expertise has been a game-changer for customers. From rings and watches to wristbands, patches, and clothes, info that when 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 folks with diabetes keep away from harmful and excessive modifications in blood sugar ranges – are among the many most up-to-date wearables to seize consideration. Permitted by the FDA to be used in diabetes, thousands and 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 plenty and buy considered one of these gadgets, know that diabetes consultants are unified of their issues that CGMs usually are not fairly prepared for the buyer marketplace for individuals who don’t have diabetes however need 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,” stated Tamara Oser, MD, director of the first care diabetes lab on the College of Colorado Anschutz Faculty of Medication in Aurora. 

Regardless of their rising reputation, Oser stated “we must be conscious that we don’t have actually robust proof but that they’re going to trigger a change in outcomes,” she stated.

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 progressively goes down. That may be a regular course of,” stated Marc Kai, MD, an internist at Mercy Medical Heart in Baltimore. “In somebody with diabetes, the quantity might go greater, last more, and take longer to return right down to regular; that’s why we use these screens: so we are able to 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 vitamin guide primarily based in Northern Virginia. An instance is consuming oatmeal, which one social media influencer compares to being “chased by a Siberian tiger.” 

Some folks have been seeing knowledge that confirmed their blood sugar spiked after consuming oatmeal. “However that’s simply the way in which your physique works; you simply ate a carbohydrate,” she stated. 

“There’s so many elements,” Omar stated. “What was within the oatmeal, what sort of oatmeal was it?  “Was it fast oats, metal reduce, or in a single day oats? What was in it? Was it sugar or jelly? A banana? Oat milk? You realize, there are such a lot of issues that may have been the true purpose why their blood sugar spiked.”

Omar’s issues usually are not unfounded. David Lam, MD, an endocrinologist and affiliate professor at Icahn Faculty of Medication at Mount Sinai in New York Metropolis, stated “it’s pure to have a glucose tour. Though CGMs can in all probability inform folks what their baseline is likely to be and provides optimistic reinforcement to cut 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 have 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 properly. Researchers are additionally wanting into the advantages for different teams, together with folks 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 determination,” he says. “Simply because the expertise exists and is FDA-approved for particular medical circumstances, it doesn’t imply that everybody will be on them. Once I prescribe a CGM for my sufferers, it’s at all times with a dialogue about what it could actually provide, 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 stated, noting that the measurement will help an individual keep away from harmful and sometimes 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 take a look at, which measures common blood sugar ranges over a 3-month interval.

Not like a finger prick, which measures the sugar focus in blood, “CGMs measure the sugar focus within the tissues simply exterior the bloodstream – the ‘interstitial’ fluid and state that exists within the tissues,” Kai stated. “Fundamental science dictates that it’s going to be about the identical.”

He stated 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. Realizing this info, which is named “time in vary,” will help form conduct (e.g., avoiding sure desserts) and information remedies or modifications in food regimen and life-style. 

What You Must Know

There’s little doubt 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 Scientific Analysis Unit, stated at the 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 folks are you able to assist keep away from or delay it, or if not keep away from it, at the least enhance it?”

Ovalle stated extra analysis is required so “we’ll be capable of know what’s really regular and really irregular past the glucose tolerance take a look at.”

A minimum of for now, the expertise wants to enhance. Oser stated 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 bought so alarmed, she went to the emergency room and it was a false low,” Osler stated. Issues like incorrect placement on the physique, dehydration, and even pores and skin trauma the place you place it could actually additionally affect accuracy.

One other essential consideration is that meals isn’t the one issue that may affect blood sugar ranges. “Glucose is known as a window into physiology,” Lam stated. “Exterior of the apparent, train, totally different stressors (together with sickness), hormones that assist our bodies struggle an infection, sleep, drugs, all of these items can enhance insulin resistance and glucose ranges.”

One of many potential pitfalls of a wholesome individual utilizing a steady glucose monitor is info overload,  Kai stated. 

“Blood sugar varies from individual to individual, so people are going to search for 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 stated.

In case you are nonetheless inquisitive about attempting a steady glucose monitor, on the very least, contact your physician or a dietitian who will help you perceive what the numbers are telling you and how one can harness them in a method that is sensible on your private well being.
