SIBO analysis is a breath test used to evaluate the amount of hydrogen and methane gas produced by bacteria in the small intestine. Instead of obtaining a sample from this area, the patient drinks a sugar solution and provides several breath samples over a set period. Early and delayed measurements help professionals identify abnormal gas production that may contribute to symptoms such as bloating, abdominal discomfort, diarrhea, constipation, or persistent fullness.

Accurate preparation is essential because many everyday choices can distort the test. Food, antibiotics, proton-pump inhibitors, antidiarrheal products, and smoking may influence intestinal bacteria and gas production. A testing laboratory usually provides detailed instructions, but patients should also discuss current medications and supplements with the healthcare professional supervising their care. Following the preparation protocol reduces the risk of misleading results.

It is also helpful to remember that SIBO analysis does not explain every digestive concern. The hydrogen and methane responses observed on a breath test can have different causes, and the results should be interpreted alongside symptoms, dietary patterns, medical history, and other appropriate evaluations. Symptoms alone are not sufficient for diagnosis.
