Abstract:
Ulcerative colitis (UC) is a chronic inflammatory disease affecting the colorectum, posing a significant global health burden. Recent studies highlight the critical role of gut microbiota and its metabolites, particularly bile acids (BAs), in UC's pathogenesis. The relationship between BAs and gut microbiota is bidirectional: microbiota influence BA composition, while BAs regulate microbiota diversity and activity through receptors like Farnesoid X receptor (FXR) and Takeda G protein-coupled receptor 5 (TGR5). Targeting bile-acid metabolism to reshape gut microbiota presents a promising therapeutic strategy for UC. This review examines the classification and synthesis of BAs, their interactions with gut microbiota, and the potential of nutritional and microbial interventions. By focusing on these therapies, we aim to offer innovative approaches for effective UC management.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
