SIBO 3 Hour Breath Test

Small intestinal bacterial overgrowth (SIBO) is a common condition that can contribute to bloating, gas, abdominal pain, diarrhea, or constipation. This non-invasive at-home breath test measures hydrogen (H₂) and methane (CH₄) gases after lactulose ingestion to detect bacterial or methanogen overgrowth in the small intestine. Results allow Root doctors to provide clear direction for addressing gut imbalances and improving digestive health.
