Impacto del Sobrecrecimiento Bacteriano del Intestino Delgado (SIBO) en el Síndrome De Intestino Irritable (SII)

Abstract

Introduction: Given the complex interaction between small intestinal bacterial overgrowth and irritable bowel syndrome, which significantly complicates the lives of those affected, this review is necessary to understand how appropriate treatment of these conditions can substantially improve their well-being. Literature Review: This narrative review aimed to explore how small intestinal bacterial overgrowth (SIBO) influences irritable bowel syndrome (IBS). A meticulous search was conducted in databases such as PubMed, SciELO, and Scopus, selecting 39 articles published between January 2019 and December 2023, using specific inclusion and exclusion criteria. The results were organized in tables, and ethical issues were addressed, avoiding the direct involvement of patients. The terms MeSH, DeCS, and Emtree were combined with Boolean operators to refine the search. The findings revealed that a significant proportion of IBS patients also suffer from SIBO, which worsens symptoms such as abdominal pain and bloating. Treatments targeting SIBO, particularly antibiotics and probiotics, effectively improved digestive function and alleviated symptoms. This underscores the importance of considering SIBO in the clinical treatment of IBS. Conclusions: The literature review underscores that effective treatment of IBS is crucial in mitigating its symptoms. It highlights that a proper diagnosis and treatment of IBS can be a decisive factor in improving the quality of life of IBS patients.
