Episode notes
What SIBO Is And Why It Causes Symptoms
- SIBO is bacteria overgrowing in the small intestine and fermenting food, producing excess gas.
- That misplaced fermentation causes severe bloating and altered stools like diarrhea or constipation.
Three Types Of SIBO Gas
- Methane commonly slows gut transit and links with constipation.
- Hydrogen causes diarrhea and hydrogen sulfide produces foul, sulfurous gas and protein intolerance.
Use Low FODMAP As A Practical Screen
- Try a low FODMAP diet for one week to see if bloating improves as a simple SIBO screen.
- If it helps, get a breath test to confirm and guide treatment.
