Summary

This study collects breath samples from 235 people with type 2 diabetes or obesity to improve a device that estimates blood sugar from exhaled air. Participants breathe into a portable analyzer that measures volatile organic compounds. The goal is to gather data to refine the device's algorithm, potentially offering a non-invasive alternative to traditional glucose monitoring.
