Noick Jonas launched his new album, Sunday Best. But the cover photo is not just a promotional image: it is a way of living with diabetes. In the shot, in fact, the singer appears from behind, and is clearly visible on his arm a small circular device. This is a sensor for the continuous blood glucose monitoring. A choice that is anything but random for the artist, who has lived with type 1 diabetes since he was 13 years old. And in aexclusive interview with People on the occasion of the album’s launch, he talked about how much technology has become an integral part of his daily life. Jonas also explained how he talked to his daughter about the disease and how it works CGM device that he wears on his arm. Which is an increasingly widespread monitoring system: that’s it what it is and how it works.
What are CGM devices
CGM systems, acronym for Continuous Glucose Monitoringare devices designed to monitor glucose levels continuously throughout the day. According to an in-depth study published on Nurse24these tools detect the concentration of glucose in the interstitial fluid through a small sensor inserted under the skin. The collected data is then sent via a transmitter to a dedicated receiver or smartphone, allowing you to view glycemic trends in real time. Compared to traditional fingerstick measurement, which returns an isolated value, CGMs offer a continuous reading. And thus they allow you to observe how blood sugar varies over time, making it easier to identify fluctuations and trends.
How glucose sensors work
From a technological point of view, CGMs are composed of a subcutaneous sensora transmitter that sends data and a display system to consult glycemic values. They exist different types of CGM devicesfrom those that require a small outpatient procedure to insert the sensor under the skin to “disposable” ones. The latter can be positioned directly at home using an applicator. The A report on CGM systems published by Ministry of Health highlights that these devices carry out measurements at very close intervals. And I am able to generate detailed graphs on blood sugar trendsas well as sending automatic alerts if values are too low or too high. The availability of real-time information allows you to understand not only the current glycemic value, but also the speed with which it is changing, an essential fact to modulate insulin therapy and prevent critical events.
CGM and type 1 diabetes: why they are considered important tools
The Guidelines on the therapy of type 1 diabetes of theHigher Institute of Healthupdated in 2024, highlight the central role of continuous monitoring of glucose in improving metabolic control, especially in patients following intensive insulin therapy. According to clinical recommendations, the use of CGMs allows for reduce the frequency of hypoglycemic episodesin particular during the night hours, and to increase the so-called “time in range”, i.e. the period in which blood sugar levels remain within the values considered optimal. Furthermore, the availability of continuous data favors a greater patient awareness compared to the impact of nutrition, physical activity and drug therapy.
From measurement to automatic administration: technological evolution
In recent years, CGM systems have been progressively integrated with insulin pumps and advanced software, giving rise to devices capable of communicating with each other and automatically adapt insulin administration. An in-depth study published by Humanitas University highlights how these technologies represent a significant step towards automated systems increasingly advanced, often called artificial pancreases, in which glycemic data directly guide insulin regulation. These solutions reduce the management burden of the disease and improve therapeutic safetybringing diabetes management closer to an increasingly personalized model.
Are CGMs also sustainable from an economic point of view?
In addition to the clinical benefits, the diffusion of continuous monitoring systems has also been analyzed under the economic profile. According to one evaluation published byAssociation of Diabetes Doctorsthe use of CGMs in adult patients with type 1 diabetes results cost effectivesince improved glycemic control helps reduce the risk of acute and chronic complications, with positive effects also on the sustainability of the healthcare system in the long term.
Who to contact to use CGM systems
Access to continuous glucose monitoring devices is through a structured clinical path. The first reference for the patient is generally the diabetologistthe specialist who evaluates the indication for using the device based on the type of diabetes, the metabolic profile and individual needs. The general practitioner can represent a first point of orientation and direct the patient towards a diabetes centre, but the prescription and management of CGMs usually fall within specialist expertise.
The Guidelines ofHigher Institute of Health they point out the importance of a personalized path which includes training in the use of the device, clinical monitoring and periodic evaluation of therapeutic results. Furthermore, in many Italian regions, access to CGMs occurs through regional welfare programs which establish eligibility criteria and supply methods, with the aim of ensuring appropriate and safe use of the technologies.
Technology and daily life: the testimony of Nick Jonas
The personal story of Nick Jonas represents a concrete example of the impact that these technologies can have on quality of life. The singer has said several times how glycemic sensors and insulin administration devices allow him to face work, travel and family life with greater serenity. The possibility of receiving automatic notifications and checking glycemic values in real time reduces the uncertainty linked to disease management and contributes to greater autonomy.
The future of diabetes management passes through technology
In recent decades, technological innovation has profoundly transformed the therapeutic approach to diabetes. CGM systems represent today one of the most advanced tools for metabolic monitoring and are helping to redefine the relationship between patient and disease. The growing diffusion of these solutions, supported by scientific evidence and clinical recommendations, confirms the central role of continuous monitoring in personalized diabetes medicine, in which data, automation and prevention become key elements of the treatment path.
