Small intestinal bacteria overgrowth (SIBO) is a condition in which too many bacteria grow in the upper part of the small intestine. Symptom occur after eating because the bacteria in the intestine begin to consume the food in the small intestine before it can be absorbed. The bacteria then produce gases, which can cause bloating and abdominal distension. In severe SIBO from colon bacteria, patients can suffer from diarrhea, weight loss, nutrition and vitamin malabsorption.

Small Intestinal Bacterial Overgrowth (SIBO): A Prospective Clinical and Molecular Registry
Enrolling: Yes
Principle Investigator: John M. Wo, MD
Primary Outcomes Measured: To determine the prevalence of risk factors of SIBO in patients with coliform SIBO and aerodigestive tract SIBO.
Secondary Outcomes Measured:
- A registry of patients undergoing proximal jejunal aspiration for suspected SIBO to collect data on demographics, SIBO symptom scores, clinical complications, presence of functional gastrointestinal disorders, and vitamin and nutrient deficiencies.
- Characterize the clinical differences between coliform SIBO and aerodigestive tract SIBO.
- Compare the composition between luminal and mucosal bacteria in the proximal small bowel
- Compare the results of bacteria species from molecular identification between luminal aspiration samples and mucosa biopsy samples.
