Hábitos alimentarios, síntomas y enfermedades subyacentes asociadas a sobrecrecimiento bacteriano intestinal (SIBO): Un estudio en consulta privada en Bizkaia.

Nowadays, small intestinal bacterial overgrowth (SIBO) is a gastrointestinal condition linked to various digestive, nutritional, and metabolic disorders. This microbial imbalance can impair nutrient absorption, leading to vitamin deficiencies and disruptions in the digestive tract. Common symptoms include bloating, diarrhea, abdominal pain, and fatigue, all of which significantly impact patients' quality of life. Additionally, SIBO is often associated with underlying conditions such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), celiac disease (CD), and diabetes mellitus (DM), among others. Objective: To evaluate the eating habits, symptoms, and associated diseases in patients diagnosed with SIBO. Materials and Methods: A cross-sectional descriptive study was conducted with a sample of 34 patients diagnosed with SIBO through lactitol breath tests. Data on symptoms and food frequency were collected. Statistical analyses included Chi-square, Spearman correlation, and Kruskal-Wallis tests, with a 95% confidence interval. Results: The most frequently consumed foods among patients were fruits (mean: 34.75 ±29.80) and vegetables (mean: 19.54 ±15.04), while the least consumed were pastries (mean: 9.56 ±15.98) and fish (mean: 8.29 ±12.95). Significant associations were identified between meat consumption and diseases such as gastritis and gastroesophageal reflux disease (GERD) (p=0.031), as well as between legume consumption and combined symptoms (p=0.006). Conclusions: The findings underscore the influence of dietary patterns on symptoms and diseases associated with SIBO, highlighting the importance of personalized dietary approaches. This study provides valuable data for designing nutritional management strategies to optimize the quality of life for patients with SIBO.
