Abstract

This study investigates the complex interplay between gut microbiota and inflammatory bowel disease (IBD), focusing on the mechanistic links, environmental modulators, and emerging therapeutic strategies. Drawing on recent multi-omics, clinical, and experimental evidence, we highlight how microbial dysbiosis—characterized by reduced diversity and altered abundance of key genera such as Faecalibacterium and Akkermansia—is strongly associated with both Crohn’s disease and ulcerative colitis. Our analysis reveals that IBD patients exhibit elevated pro-inflammatory cytokines (e.g., TNF-α, IL-6) and compromised intestinal barrier function, as evidenced by increased zonulin levels and disrupted tight junction proteins. Diet as a modulator of processes of disease became apparent; A Western diet pattern is associated with increased dysbiosis and inflammation, while fibre-rich and Mediterranean-style meal patterns are able to increase the diversity of gut microbes and relieve symptoms.  Similarly, studies demonstrate that alterations of circadian rhythm, such as occupational shifts, including shift work and irregular sleep patterns, significantly impact microbiome structure and reduce the level of beneficial bacteria populations.  Regarding the therapeutic approaches, there was a proven marginally efficacious modus operandi of probiotics in diminishing inflammation and bringing about remission. By improving microbial richness and extending the period of remission, FMT showed higher clinical results particularly in patients with ulcerative colitis.  Our results identify the gut flora as a treatable target and a lucrative biomarker in IBD.  The IBD management, given the future perspective, focuses on the priority of precision nutrition, chrono-microbiome synchronization, and microbiota-driven medicine.  Out of these insights are conceived more customized and environmentally friendly therapy strategies aimed at restoring intestinal stability and better patient outcome.
