Abstract
Small Intestinal Bacterial Overgrowth (SIBO) is characterized by an excessive increase in bacteria in an area that normally has a restricted microbiota. This study aims to review the clinical features, diagnostic methods, risk factors, and treatment options for SIBO, with a particular focus on its prevalence in chronic diseases such as irritable bowel syndrome (IBS) and functional diyspepsia, diabetes, and liver diseases. The review highlights the variability in diagnostic methods and the absence of a gold standard, which limits diagnostic accuracy. Among treatment options, antibiotics, probiotics, and herbal therapies (phytotherapy) show potential in symptom management. The need for standardized diagnostic criteria and further research on integrative therapies is emphasized to optimize clinical practice in the treatment of SIBO.
