flag Breath tests may reveal gut health by detecting bacteria-linked compounds, offering a non-invasive alternative to stool tests.

flag A new study finds that exhaled breath contains volatile metabolites linked to specific gut bacteria, including one associated with asthma, suggesting breath analysis could non-invasively reveal gut microbiome health. flag Researchers from Washington University in St. Louis analyzed breath samples from mice and 41 children, identifying correlations between breath compounds and gut microbes. flag The approach could offer a simpler, faster alternative to stool testing for diagnosing conditions influenced by gut bacteria, though further research is needed to fully understand the complex interactions.
