Quick answer
Hydrogen-leaning and methane-leaning SIBO patterns often need different tactical emphasis. Methane patterns usually require stronger constipation and transit strategy; hydrogen patterns often present with more rapid fermentation symptoms.
Pattern differences
- Hydrogen-leaning: gas, bloating, meal-triggered fermentation spikes.
- Methane-leaning: constipation, slow transit, persistent fullness.
Bottom line: phenotype-aware treatment improves consistency and lowers relapse risk.
