Clinical Trial Summary

Irritable bowel syndrome is characterized by abdominal discomfort and bowel habit change. It is increasing worldwide. But the pathophysiology of the irritable bowel syndrome is not proven. So, the treatment's target is the relief of the symptoms.

Small intestinal bacterial overgrowth considered as the cause of the irritable bowel syndrome. Because, it is related to the postprandial abdominal discomfort and the abdominal discomfort could be relieved after taking antibiotics. There are several diagnostic methods for small intestinal bacterial overgrowth. hydrogen breath test is non-invasive method for diagnosis of the small intestinal bacterial overgrowth. But, there is no standardized cut-off value for the hydrogen breath test. So, we want to compare the hydrogen breath test between the irritable bowel syndrome patients and normal people. And then, we want to analyze the efficacy of hydrogen breath test for the diagnosis of irritable bowel syndrome.
