I published the following summary of a recent research study on probiotics last October, and am republishing it now. The reason is that the demise of Zelnorm calls for sound solutions backed, if possible, by medical research. Note that this site has never endorsed Zelnorm. Here’s the summary–
A study of the use of probiotics with both IBS-C (IBS with constipation) and IBS-D (IBS with diarrhea).
The study is summarized in a press release from the Annual Meeting of the American College of Gastroenterology, the major medical association for Tummy Doctors (Gastroenterologists), the ones who send you for colonoscopies and that fun stuff. The paper that was presented should, if all went well and there were no major editorial questions, be hitting the medical journals about now. I’ll keep an eye out for it.
A quick summary: The paper, delivered in 2005 to the American College of Gastroenterologists, found that in a controlled study, which I hope was double-blind, that both experimental groups, IBS-C and IBS-D, improved with probiotics over those who received a placebo, over a four week period.
