Updated March 27, 2026
Treatment for SIBO (Small Intestinal Bacterial Overgrowth) focuses on symptom control, prevention of complications, and quality-of-life improvement. SIBO occurs when excessive bacteria colonize the small intestine, causing bloating, abdominal pain, diarrhea, and malabsorption. It is diagnosed with breath testing and treated with antibiotics and dietary modification.
Clinical Context
The primary approach involves condition-specific pharmacological and non-pharmacological therapy guided by clinical guidelines. Monitoring typically includes condition-specific biomarkers and clinical assessment at scheduled review. Treatment intensity is tailored to disease severity, patient comorbidities, and response. Guideline-directed therapy reduces the risk of complications, hospitalisation, and disease progression.
