SIBO Treatment: Methane vs Hydrogen Patterns (Practical Differences)

D2 • Feb 28, 2026 • 9 min read

A practical phenotype-aware SIBO guide comparing methane-leaning vs hydrogen-leaning treatment priorities.

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.
