OMED Health Breath Analyzer
Test for SIBO with a certified medical at-home hydrogen and methane breath testing device
SIBO Diagnostics Through Breath Testing
The OMED Health Breath Analyzer measures hydrogen and methane in your breath – gases are produced by gut microbes as they ferment food. Used as part of your SIBO test, the device tracks these gas levels throughout your testing window, giving your practitioner clear insight into how your gut is responding and whether an imbalance such as SIBO or IMO could be driving your symptoms.
- Clinical-grade performance as accurate as hospital breath testing.
- Approved medical device, regulated for clinical use.
- Measures hydrogen and methane directly in parts per million.
- Used exclusively as part of a SIBO test ordered through your healthcare professional.
OMED Health App
The OMED Health App guides you through your SIBO test from start to finish. Seamlessly connected via Bluetooth to your OMED Health Breath Analyzer, the app records each breath sample in real time throughout your testing window, while you log any symptoms you experience along the way.
Your results don’t just stay on your device — hydrogen and methane data syncs in real time to your healthcare professional’s portal, so they can follow your progress as the test happens and have your full report ready to review the moment testing is complete.
Your SIBO Test Report
Your OMED Health Report turns your breath test into a clear, clinical diagnosis. Your hydrogen and methane results are reviewed by an OMED Health doctor, who interprets your gas curves alongside any symptoms you logged during testing to determine whether SIBO or IMO is present.
Your report, including your official diagnosis, is delivered as a PDF and shared directly with your healthcare professional, giving them the precise data they need to guide your treatment.
- Doctor-reviewed diagnosis – not just raw data, a clinical interpretation of your results.
- Clear hydrogen and methane readings – presented in parts per million, mapped across your test window.
- Symptom correlation – see how your logged symptoms line up with your gas levels during testing.
Doctor-Led Diagnosis of Methane-Dominant SIBO (IMO)
High methane levels on a breath test are often linked to a type of gut overgrowth called methane-dominant SIBO. Doctors now use the term Intestinal Methanogen Overgrowth (IMO) because, unlike typical SIBO, methane is produced by a different group of microbes called methanogens. When these microbes overgrow, they can slow gut movement, which may lead to constipation, bloating and discomfort.
The OMED Health Breath Analyzer measures methane with clinical precision, making it possible to accurately identify IMO. If your healthcare professional wants to track how you’re responding to treatment, they can request a re-test using the same device, giving them clear data on how your methane levels are changing over the course of antibiotics, antimicrobials, diet, or other therapies.
Following your SIBO test, an OMED Health doctor reviews your results and provides a clinical diagnosis. This gives your healthcare professional the clarity they need to plan your next steps toward recovery.
Your Healthcare Professional Leads Your Care
OMED Health provides the test — your healthcare professional provides the care. Every SIBO test is ordered on your behalf by an approved practitioner, who uses your results to guide what happens next, whether that’s dietary changes, antimicrobials, antibiotics, or a combination tailored to your diagnosis.
This means you’re never left interpreting a report alone. Your practitioner has the clinical expertise to turn your hydrogen and methane data into a treatment plan built around you, and to adjust that plan as your results and symptoms evolve.

Insights
Why Test for SIBO?
Chronic bloating, discomfort, and unpredictable bowel habits are often written off as general IBS. But for many people, an underlying gas-producing overgrowth is the real driver behind those symptoms. Breath testing replaces guesswork with objective data, giving you and your healthcare professional a clear starting point for treatment.
Is IBS actually SIBO?
Not exactly — but the two overlap far more than most people realise. IBS is a diagnosis based on symptoms, while SIBO is a specific, testable overgrowth that can be causing those symptoms in the first place. Studies suggest a significant proportion of people diagnosed with IBS actually have undiagnosed SIBO. Read more about IBS vs SIBO
What’s driving my constipation or bloating?
Your hydrogen and methane levels point to different underlying patterns. Higher methane is strongly linked to slower gut motility and constipation, while higher hydrogen is more commonly associated with bloating, gas, and looser stools. Identifying which gas is elevated helps your practitioner understand what’s actually happening in your gut, rather than treating symptoms generically.
Is my treatment working?
Once you’ve started a treatment plan, it can be hard to know if it’s actually working until symptoms fully resolve — which can take weeks. If your healthcare professional wants objective proof of progress sooner, they can request a re-test using the same device, comparing your new hydrogen and methane levels against your original results.
How accurate is the test?
The OMED Health Breath Analyzer is a clinical-grade, approved medical device with published accuracy data for both hydrogen and methane. Every result is reviewed by an OMED Health doctor before being returned as a diagnosis, so you’re getting a medically validated result, not a rough estimate.

FAQS
Find answers to your common questions about the OMED Health Breath Analyzer
In which countries is OMED Health available?
The App is available to download in the UK, Europe and the USA. However, diagnostics and medical services are currently available in Great Britain only.
What do the results mean?
The OMED Health Breath Analyzer measures hydrogen (H₂) and methane (CH₄) gases produced when gut microbes ferment food.
High hydrogen levels after eating certain foods, especially carbohydrates such as bread, pasta, beans, or high FODMAP foods, can suggest that these foods are being fermented earlier than normal, which may contribute to bloating, pain, or diarrhoea.
High methane levels are usually linked to intestinal methanogen overgrowth (IMO), which can slow gut movement and contribute to constipation. Clinical guidelines typically consider methane levels above 10 ppm at any point during testing as indicative of significant methanogen activity.
Is the OMED Health Breath Analyzer a medical device?
Where can I see technical specifications and performance data?
