6Īnother way we have emphasized the difference rather than the similarity The varying symptoms in IBS have led to efforts lookingĪt differences rather than similarities between patients. Or unifying framework has been available to explain the different symptomsĪnd findings of IBS. Symptom-based approach has been used because no consistent biological marker IBS is a diagnosis made on the basis of meeting clinical criteria. Irritable bowel syndrome (IBS) is a common diagnosis that affects 11% Of the central nervous system, and increased sympathetic drive and immuneĪctivation may be understood as consequences of the host response to SIBO.Ĭonclusions The gastrointestinal and immune effects of SIBO provide a possible unifyingįramework for understanding frequent observations in IBS, including postprandialīloating and distension, altered motility, visceral hypersensitivity, abnormalīrain-gut interaction, autonomic dysfunction, and immune activation.

Altered gastrointestinal motility and sensation, changed activity The type of excreted gas, a prevalence of abnormal lactulose breath test inĨ4% of IBS patients, and a 75% improvement of IBS symptoms after eradication Lactulose ingestion, a correlation between the pattern of bowel movement and Of pertinent articles and books were also scanned for additional suitableĮvidence Synthesis The possibility that small intestinal bacterial overgrowth (SIBO) mayĮxplain bloating in IBS is supported by greater total hydrogen excretion after May exist since 92% of these patients share the symptom of bloating regardlessĮvidence Acquisition Ovid MEDLINE was searched through May 2004 for relevant English-languageĪrticles beginning with those related to bloating, gas, and IBS. Although no conceptual frameworkĪccounts for all the symptoms and observations in IBS, a unifying explanation Is a puzzling condition with multiple models of pathophysiology includingĪltered motility, visceral hypersensitivity, abnormal brain-gut interaction,Īutonomic dysfunction, and immune activation.
