Imagine a tiny sensor, like a small sticker, that checks your blood sugar levels all day.
These are called Continuous Glucose Monitors (CGMs).
They are super helpful for people with diabetes because it helps them manage their blood sugar.
Now, people without diabetes are also using them to see how their food and activity affect their bodies.
However, experts are unsure if these monitors are necessary for people who aren't diabetic.
They may also lead to unnecessary worry if you see normal blood sugar fluctuations.
