"I guess the question in my mind is if probiotics and kefir help (in fact clear up) my diarrhea problem (too early to say cure), is this still potentially IBS-D? Or is it just an altered gut flora that desparately needs rebalancing."Could certainly still be IBS. Probiotics have had some potential for treating IBS, mainly pain and bloating, but there can be trasnsient "bad" bacteria that can trigger IBS. They are looking at the interactions of bacteria and the gut as we speak and the flora is different in people and where they live, if there under stressors etc... It also is really complex. People also don't or maynot fully realize what effects stress and emotions has on altering the bacterial flora. There can also sometimes be some bad bugs in there, but its not looking like bacteria will be the sole answer to IBS itself, but more contribute to the problem or help the problems.One thing here is they have found abnormalities in IBSers and it has to do with how the brain and gut interact.You should read this because its very important.

Quigley M.D., Alimentary Pharmabiotic Centre, University College Cork, Cork, IrelandBacteria are present in the normal gut (intestines) and in large numbers the lower parts of the intestine. These "normal" bacteria have important functions in life. A variety of factors may disturb the mutually beneficial relationship between the flora and its host, and disease may result. The possibility that gut bacteria could have a role in irritable bowel syndrome (IBS) may surprise some; there is indeed, now quite substantial evidence to support the idea that disturbances in the bacteria that populate the intestine
may have a role in at least some patients with IBS. This article presents a discussion of the possible role of bacteria in IBS and various treatment approaches."Do bacteria play a role in IBS?The possibility that gut bacteria could have a role Irritable Bowel Syndrome (IBS) may surprize some; there is indeed, now quite substantial evidence to support the idea that distrubances in the bacteria that populate the intestines may have a role in at least some patients with IBS. What is this evidence? It can be summarized as
follows:1. surveys which found that antibiotic use, well known to distrub flora, may predispose individuals to IBS.2. The observation that some individuals may develop IBS suddenly, and for the first time, following an episode of stomach or intestinal infection (gatroenteritis) caused by a bacterial infection.
My note: (post infectious IBS) There are important structural cell changes in PI IBS and PI IBS has been demonstarted now as a brain gut axis issue.3. recent evidence that a very low level of inflammation may be present in the bowel wall of some IBS patients, a degree of inflammation that could well have resulted from abnormal interactions with bacteria in the gut.Note: This is complex as well and also has brain gut axis involved with stress and mast cells, something called neurogenic inflammation. So here many factors can be involved.4. The Suggestion that IBS maybe Associated with the abnormal presents, , in the small intestines, of types and numbers; a condition termed small bacterial overgrowth (SIBO)>Note: This is still slightly controversal and not looking like the "cause" of IBS, but some people may have sibo and IBS.5. Accumaliting evidence to indicate that altering the bacteria in the gut, by antibiotics or probiotics, may improve symptoms in IBS.Note: its important to look at what improvements and whay here.For some time, various studies have suggested the presence of changes in the kind of colonic flora in IBS patients.
The most consistent finding is a relative decrease in the population of one species of 'good' bacteria, bifidobacteria.However, the methods employed in these studies have been subject to question and other studies have not always reproduced these finding. Nevertheless, these changes in the flora, maybe primary or secondary, could lead to the increase of bacterial species that produce more gas and other products of their metabolism. These could CONTRIBUTE to symptoms such as gas, bloating and diarrhea.""We still don't know the exact role bacteria has in IBS. More research is needed."
