Abstract The gut microbiota plays a critical role in maintaining human health, influencing wide range of physiological processes, including immune regulation, metabolism, and neurological function. Recent studies have shown that imbalances composition can contribute to the onset progression various diseases, such as metabolic disorders (e.g., obesity diabetes) neurodegenerative conditions Alzheimer's Parkinson's). These are often accompanied by chronic inflammation dysregulated responses, which closely linked specific forms cell death, pyroptosis ferroptosis. Pathogenic bacteria trigger these death pathways through toxin release, while probiotics been found mitigate effects modulating responses. Despite insights, precise mechanisms influences diseases remain insufficiently understood. This review consolidates recent findings on impact immune‐mediated inflammation‐associated conditions. It also identifies gaps current research explores potential advanced technologies, organ‐on‐chip models microbiome–gut–organ axis, for deepening our understanding. Emerging tools, single‐bacterium omics spatial metabolomics, discussed their promise elucidating microbiota's disease development.
