The story

I've tested positive for very high methane levels in multiple breath tests. I've been through two rounds of Rifaximin + Neomycin and they haven't made a difference. The fatigue and bloating are my biggest symptoms.

Thanks for sharing. I've been there. What's your diet like? I also have high methane tests and since cutting out garlic and onion I've seen a notable improvement in my symptoms.

This is one person's reported experience aggregated by GutPattern, not clinical advice, a treatment protocol, or a diagnosis. What helped one contributor can do nothing — or harm — for someone with a different underlying cause. Sudden, severe, bloody, feverish, or worsening symptoms belong with medical care. Always discuss care decisions with a qualified clinician.
