People suffering from colon cancer and obesity have very high levels of Euryarchaeota bacteria in their gut. The methane can be exhaled on your breath, eliminated in your stool, or absorbed into your blood. Irritable bowel syndrome (IBS) is an extremely common and often very debilitating chronic functional gastrointestinal disorder. Diet for Methane SIBO. Classified as chemolithotrophic or methylotrophic methanogens. Part of that hydrogen is gobbled up by M. smithii, which then produces methane. Research to Enhance Activities for Community Health (REACH): Assessing the impact of social marketing and theory-based intervention strategies on participant involvement, retention, and health outcome. They do not form a monophyletic group, however, meaning that all the methanogens do not consist of a single ancestor and all its descendants. In contrast, the Achaea that exist in the gut are mostly comprised of methanogens (producers of methane) and specifically by Methanobrevibacter smithii – a hydrogen-consumer. This microorganism is responsible for breaking down complex sugars and produces methane as a by-product. 2010, 2011].
