Abstract

Small intestinal bacterial overgrowth (SIBO) is a condition characterized by high bacterial population in small intestine. Its overall worldwide prevalence is unknown due to under diagnosis and unspecific symptoms. In clinical setup, diagnosis of SIBO is still a big challenge. Aspiration and breath tests are two possible diagnostic tests. The study objective was to find prevalence of SIBO in individuals using Glucose H₂ and CH₄ breath tests and to develop association of SIBO with age, gender, BMI, food and exercise. Total 385 individuals participated in study. Initial screening was done using symptomatic questionnaire, filled by respondents in an interview style to find out suspected individuals. Total sum of each symptom was calculated. Individuals with total score of ≥5 were considered suspected for SIBO and further proceeded for confirmation through Glucose Breath Test (GBT) using 50g glucose in 200 mL water. Individuals having at least 12 ppm increase in H₂ and / or CH₄ over the lowest preceding value or the basal reading within test period, were considered as positive for SIBO. Chi-square test was applied to find correlation between various factors. P value < 0.05 was considered as significant. On the basis of screening, 14.02% individuals were found suspected to have SIBO on the basis of positive gastro-intestinal signs and symptoms. In overall tested population, 4.42% individuals were observed as SIBO positive, 9.61% were false positive and 85.97% were negative for SIBO. Prevalence was high among individuals consumed starchy food (70.6%) and did not performed exercise (65%). There is no association of SIBO with age, gender and BMI. It can be concluded that SIBO is present among individuals with gastro-intestinal signs and symptoms. Testing SIBO with both H₂ and CH₄ gave better possible results as compared to individual gas testing.
