We talk with Boston University researcher Nicole Spartano, PhD about what continuous glucose monitoring can reveal in people without diabetes and why those patterns may matter for future diabetes and cardiovascular risk. We dig into Framingham Heart Study findings (https://diabetesjournals.org/care/article/doi/10.2337/dc26-1197/172437/Beyond-Traditional-Glycemic-Measures-CGM-Glycemic), why A1C may not match CGM in non-diabetes ranges, and how to avoid overreacting to glucose spikes.
