Patients Without Diabetes
Now there is another question. We have discussed patients with type 2 diabetes without insulin. It’s trendy to talk about the potential benefits of continuous glucose monitors in patients without diabetes. The idea is emerging that these monitors could be used to refine the diagnosis of diabetes or to better predict the onset of diabetes in the subsequent years.
Others claim that continuous glucose monitors are an effective way to induce a change in dietary and physical activity behaviors in patients with prediabetes. One can, for example, tell a patient, “You are at risk of developing diabetes, so by monitoring your glucose, you will change your behavior.” Honestly, the scientific data we have today do not support these ideas, and I sincerely believe that it is not advisable today to recommend, as some would like, the mass use of monitors, whether in patients with overweight or obesity, or in patients with prediabetes. This goes for suggestions for using the monitor for 7-10 days per year, in the form of a session to try to reduce the risk for diabetes by motivating patients to change their behavior. We have no evidence at all that this can work. And in my opinion, with this kind of discourse, we ultimately risk, as usual, encouraging patients who are already “fans” of self-checks and self-monitoring to get health data, even if they do not know how to interpret it. Maybe even the doctor they ask for interpretation will not be trained to interpret the results of these monitors.
Spreading the idea that monitors are useful for preventing diabetes has a side effect: It hinders progress on the essential issue. Today, one of the problems in diabetes and prediabetes is that screening is not done often enough, and 20% of patients with diabetes are still unaware of their diagnosis. The management of early diabetes or prediabetes, in my opinion, is not optimal in routine care today. So, I think that adding the idea that using monitors could be beneficial dilutes the main information.
Having said that, I sometimes offer continuous glucose monitoring to some of my patients on a case-by-case basis. I believe that with proper support and an educational program, it can be beneficial for certain patients.
In Practice
In summary, I am totally opposed to the normalization of the use of monitors. I think it is our role as health care professionals to warn the public that even if it is accessible — anyone can buy a reader, a sensor — it is not necessarily beneficial, and it may even distract us from what is essential. But as a specialist, I think that using a monitor within a genuine care plan seems reasonable. Ultimately, it’s just personalized medicine.
