Our research explores the diagnostic potential of volatile organic compounds (VOCs) in human breath as non-invasive indicators of metabolic health. VOCs are emitted by the body and reflect ongoing physiological and biochemical processes. Breath, as a rich and easily accessible matrix, contains a wide range of VOCs that can provide insights into key metabolic pathways, including glucose regulation and microbiota-related metabolism.
We aim to identify distinct VOC patterns and investigate their associations with blood glucose levels, body composition, circadian rhythms, and microbiota profiles — both in individuals with diabetes and in healthy controls. Our broader goal is to contribute to the development of non-invasive, real-time diagnostic tools for personalized metabolic monitoring.
This research area includes clinical studies such as our current project registered under NCT05933616 and new investigations into circadian VOC dynamics and their interaction with microbiota in the context of metabolic disorders NCT05984979.
