It is also an opportunity to reflect on how innovation continues to improve the assessment of digestive disorders.<\/p>\n\n\n\n<p>Over the past two years, I have contributed to Bedfont\u00ae Scientific\u2019s World Digestive Health Day publications. In 2024, we explored the importance of structured investigation and the risks of <a href=\"https:\/\/www.bedfont.com\/world-digestive-health-day-2024-taking-control-of-your-digestive-health-importance-of-not-self-diagnosing\/\">self-diagnosis in digestive health<\/a><sup>1<\/sup>. In 2025, Bedfont\u00ae examined <a href=\"https:\/\/www.bedfont.com\/world-digestive-day-understanding-gut-health-and-the-power-of-hmbt\/\">the science behind hydrogen-methane breath testing (HMBT)<\/a><sup>2<\/sup> and its role in identifying small intestinal bacterial overgrowth (SIBO) and carbohydrate malabsorption.<\/p>\n\n\n\n<p>In 2026, we are looking at progress, for example, how HMBT has evolved, and how diagnostic technology such as the <a href=\"https:\/\/www.gastrolyzer.com\/gastroch4eck\/\">GastroCH\u2084ECK\u00ae<\/a> is advancing non-invasive gut diagnostics.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-left\"><strong>The Evolution of HMBT<\/strong><\/h3>\n\n\n\n<p>Historically, SIBO diagnosis relied on jejunal aspirate culture. This is an invasive, technically demanding, impractical procedure in routine care, and not cost-effective. Breath testing emerged as a patient-friendly test for diagnosing small intestinal bacterial overgrowth and carbohydrate malabsorption, though early adoption was limited by a lack of standardisation.<\/p>\n\n\n\n<p>The publication of the North American Consensus in 2017 outlined recommendations around preparation protocols, substrate dosing and diagnostic thresholds.<sup>3<\/sup> This was reinforced by the American College of Gastroenterology (ACG) Clinical Guideline in 2020, which formally recognised breath testing as a clinically appropriate tool in selected patients.<sup>4<\/sup><\/p>\n\n\n\n<p>These publications moved breath testing into a supported, structured diagnostic approach (provided that testing is carried out using recommended protocols, reliable analysers, and appropriately trained practitioners).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Standardisation in Clinical Practice<\/strong><\/h3>\n\n\n\n<p>Breath testing literature highlights that HMBT must be performed according to recommended preparation protocols and interpreted in a clinical context.<sup>3<\/sup><\/p>\n\n\n\n<p>Importantly, device accuracy and reliability play a critical role in minimising variability. Advances in sensor technology and calibration systems have improved reproducibility across clinical settings, strengthening user confidence in breath testing as a diagnostic tool.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Expanding Access: Clinic and Home-Based Testing<\/strong><\/h3>\n\n\n\n<p>Evidence suggests that home-based breath testing, when supported by appropriate testing instructions, can achieve high completion and reliability rates.<sup>5<\/sup><\/p>\n\n\n\n<p>This enables flexibility across both clinic-based workflows and home testing pathways, broadening access to diagnostic investigations while maintaining clinical confidence.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The following are some examples of commonly asked questions in relation to HMBT:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Is hydrogen-methane breath testing reliable for diagnosing SIBO?<\/li>\n<\/ul>\n\n\n\n<p>When performed according to recommended protocols and interpreted alongside clinical assessment, breath testing is considered a valuable diagnostic tool<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Why is methane measurement important?<\/li>\n<\/ul>\n\n\n\n<p>Methane levels \u2265 10 ppm are indicative of intestinal methanogen overgrowth and are often linked to constipation-related symptoms.<sup>4 <\/sup>Measuring methane alongside hydrogen enhances diagnostic precision by identifying patients whose symptoms may not be explained by hydrogen-producing bacterial overgrowth alone.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What influences diagnostic accuracy?<\/li>\n<\/ul>\n\n\n\n<p>Recent antibiotics, bowel prep, motility agents, and dietary non-compliance may affect results. Adherence to established protocols is very important.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Looking ahead, several important developments are expected to influence the next phase of breath testing:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Further international harmonisation of testing protocols, including guidance from organisations such as the British Society of Gastroenterology.<sup>6<\/sup><\/li>\n\n\n\n<li>Enhanced multi-gas detection capabilities, potentially expanding beyond hydrogen and methane.<\/li>\n\n\n\n<li>Greater precision in patient selection, improving cost-effectiveness and clinical outcomes.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Conclusion:<\/strong><\/h3>\n\n\n\n<p>HMBT has evolved to a structured, consensus-supported diagnostic tool. Advances in clinical understanding, combined with ongoing innovation in diagnostic technology, have strengthened its role in assessing SIBO, IMO, and carbohydrate malabsorption.<\/p>\n\n\n\n<p>As we mark World Digestive Health Day 2026, continued innovation will remain central to advancing digestive healthcare worldwide.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Gastrolyzer\u00ae range of HMBT devices:<\/strong><\/h3>\n\n\n\n<div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-ad2f72ca wp-block-group-is-layout-flex\">\n<p>The Gastrolyzer\u00ae range of devices, comprising the Gastro<sup>+<\/sup>&#x2122; hydrogen breath testing device and the GastroCH<sub>4<\/sub>ECK\u00ae have been helping to detect gastrointestinal disorders for over 30 years.<\/p>\n<\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"819\" height=\"1024\" src=\"https:\/\/www.bedfont.com\/wp-content\/uploads\/2026\/03\/Gastrolyzer-Reliable-HMBT-testing-819x1024.png\" alt=\"Advancing the future of hydrogen-methane breath testing\" class=\"wp-image-11398\" style=\"aspect-ratio:0.7998138370921964;width:317px;height:auto\" srcset=\"https:\/\/www.bedfont.com\/wp-content\/uploads\/2026\/03\/Gastrolyzer-Reliable-HMBT-testing-819x1024.png 819w, https:\/\/www.bedfont.com\/wp-content\/uploads\/2026\/03\/Gastrolyzer-Reliable-HMBT-testing-240x300.png 240w, https:\/\/www.bedfont.com\/wp-content\/uploads\/2026\/03\/Gastrolyzer-Reliable-HMBT-testing-768x960.png 768w, https:\/\/www.bedfont.com\/wp-content\/uploads\/2026\/03\/Gastrolyzer-Reliable-HMBT-testing.png 1080w\" sizes=\"auto, (max-width: 819px) 100vw, 819px\" \/><\/figure>\n<\/div>\n\n\n<p>The Gastro<sup>+<\/sup>&#x2122; is a portable, handheld hydrogen device for quick, easy breath analysis.
