For some users, monitoring daily breath readings reveals persistently elevated methane levels. While this can feel confusing or even discouraging, remember: these readings are giving you new information about your gut that wasn’t accessible before. Let’s explore what that means and what you can do next. ### Understanding Methane Readings Before AIRE 2, it was not possible to monitor day-to-day methane levels — so you’re helping to chart new territory for yourself and for science. What we do know: * Methane levels tend to be **less influenced by diet** than hydrogen levels. * Some users see changes in methane after eating certain foods, but others notice little difference. * Eating **low-FODMAP** can sometimes cause methane levels to rise— though this isn’t fully understood yet. * Methane can remain elevated during fasting, because methanogens can keep producing gas even without recent food intake. * Slower gut motility is often associated with higher methane, so constipation or slower transit may contribute to persistently elevated readings. * Stress levels and the timing of bowel movements can also influence methane readings. 💡 *If your levels seem puzzling, you’re not alone. Many people find methane harder to interpret than hydrogen, which is why consistent logging is so valuable.* 🔗 [Read about foods that may help with methane](https://support.foodmarble.com/en/article/foods-that-may-help-methane-1s7cm9j/) ### Can I Still Do Food Intolerance Tests? Yes! You can complete **FODMAP Challenges** even with a high baseline methane reading. Methane levels often remain relatively stable throughout FODMAP challenges. **However:** * It's best **not** to proceed with a FODMAP test if your **hydrogen** levels are above 3. * Hydrogen tends to respond more to dietary changes making it a great gas for assessing intolerances. ### Questions to Ask Yourself Reflecting on your data can help you decide on your next step: * Have you been tracking your fermentation levels for some time without seeing dietary changes affect your methane levels? * Did you complete any FODMAP Challenges despite high baseline methane? * Are your symptoms still disruptive to daily life? ### When to Seek Medical Advice If your methane levels remain high **and** your symptoms persist despite FODMAP adjustments, it could be time to consult a **qualified healthcare practitioner**. They can help: * Identify possible causes * Offer treatment options * Support you in improving your quality of life 👉 *Remember, you don’t need to navigate this alone.* ### Need personalised support?
