Continuous glucose monitors, small devices that track blood sugar levels, have gained popularity for their potential health benefits. These monitors, which send blood sugar estimates to an app, transform diabetes care and are now approved for use in non-diabetics. Companies like Dexcom and Abbott distribute these devices, selling them at around $50 per patch. However, the primary concern remains whether these monitors offer actual health improvements for users without diabetes, as normal blood sugar responses raise questions about their efficacy in healthy individuals.
'It has revolutionized their and their families' lives,' says Elizabeth Selvin, who researches diabetes at Johns Hopkins University.
The critical question is: Do they actually help people without diabetes or prediabetes improve their health?
These peaks and troughs are the normal physiological response to consuming carbohydrates, in people without diabetes,' says nutritionist Sarah Berry.
Continuous glucose monitors are only about the size of a quarter, but the companies that sell them make huge claims about their health benefits.
