Is yakult helpful in the treatment of irritable bowel syndrome?
SIBO is a common feature in IBS and in fact may be directly related to the genesis of IBS symptoms. An ERBHAL on a lactulose breath test may indicate SIBO. Antibiotics and elemental diets have been shown to be effective in treating SIBO, but the efficacy of probiotics is untested. A pilot study was undertaken to determine the effect of L. strain Shirota (Yakult(R)) on intestinal fermentation patterns of IBS patients. After 6 week of treatment with 1 x 65 mL dose of Yakult(R) daily, 9 of 14 patients (64%) completing the study had reversal of ERBHAL, with the median time of first rise increasing from 45 to 75 min (P = 0.03). Furthermore, symptoms improved in those in whom ERBHAL was corrected. The results indicate that Yakult(R) alters fermentation patterns suggesting a reduction in SIBO. ERBHAL can also indicate rapid small intestinal transit and therefore, in order to confirm the effect of Yakult(R) on SIBO, future studies will include monitoring of transit time in addition to placebo
