A combination of rifaximin and neomycin is most effective in treating irritable bowel syndrome patients with methane on lactulose breath test. However, because IMO is trickier to treat, this is combined with either oregano, neem, or berberine. As M. smithii is an archaeon and can overgrow in areas outside of the small intestine, it was recently proposed that the term intestinal methanogen overgrowth (IMO) is more appropriate for the overgrowth of these organisms. J Clin Gastroenterol. Small Intestinal Bacterial Overgrowth A Lesson in Ambiguity Jeanetta L. W. Frye, MD Associate Professor of Medicine Director, UVA GI Motility Associate Program Director, GI Fellowship firstname.lastname@example.org. When bacteria overgrow in the small intestine, it’s typically due to a motility issue, or the failure of the small intestine to clean itself out. Low K. Hwang L. Hua J. et al. It even might finally have its own name - Intestinal Methanogen Overgrowth (IMO). Learning Objectives: •Define small intestinal bacterial overgrowth •Discuss the process of testing for SIBO •Review options for treatment –Discuss the methane conundrum. Many are now labeling this condition as IMO, or Intestinal Methanogen Overgrowth, since methanogens that cause methane gas are technically not bacteria, but are part of the Archaea kingdom, and can grow in the colon as well as the small intestine. One uncontrolled trial suggested that the combination of neomycin and rifaximin might be effective. The difference between the two is that bacterial overgrowth should not occur in the small intestine because it should be sterile of bacteria. 35. DOI: … Comparing the rates of methane production in patients with and without appendectomy: results from a large-scale cohort. How does one manage so-called intestinal methanogen overgrowth? Methane dominant SIBO, also known as methane SIBO or constipation SIBO, is a form of small intestinal bacterial overgrowth. What … In some cases, IMO has been treated with a high dose of oregano and no allicin or atrantil. Commentary: Intestinal Methanogen Overgrowth (IMO) is proposed as a new name for Methane SIBO. 2010; 44: 547-550. Bacterial overgrowth happens in both the small and large intestines. The predominant microbe, called Methanobrevibacter smithii, is an archaeon which can convert hydrogen into methane, resulting in slowed intestinal transit.. Methanogens can cause a host of digestive symptoms that often go undiagnosed, or wrongly diagnosed. Intestinal methanogen overgrowth (IMO), previously known as methane-dominant SIBO, is treated with either allicin or atrantil. But for now, understanding how it differs from the more common hydrogen form of SIBO is critical to developing a treatment protocol that addresses its well established defences. The procedure is undertaken by methanogens, although certain Clostiridium and Bacteroides species can also produce CH 4. PubMed; … 26 Through this procedure methanogens obtain energy to survive and they reduce the gas molar volume in the intestine since for the production of 1 mole of CH 4, 4 H 2 moles are consumed.

The most common symptoms of methane SIBO are constipation and bloating.
