re flux (appropriate)...This forum is promoted to enhance communications and understanding of the condition referred to as IBS. Your opinions and knowledge are appreciated, however I would suggest you attempt to refrain from using excess levels of techical terminology that, you know well, will not likely be understood by most of the subscribers. Just say what you want to say in a language that is conducive to communications and leave the rest to documenting whatever major medical revelations you may be hatching.In reference to the subject at hand, I find it interesting that you would rebut the testimony and general opinons of over a hundred easily researchable internet references. Have you not ever swallowed air? Is this not a commonly accepted manifestation that results in burping, flatus and general abdominal discomfort? The MMC (Migrating Motor Complex..a series of involuntary contractions that sweep the digestive system of debris) is indeed a factor that would tend to confuse the issue of whether air/gas would not be held in the digestive system, and at the phase III point (the level of most intense MMC activity) it would seem likely that all materials would have been flushed. However,by the admission of even the most informed of researchers and physicians, there is MUCH that we don't know about IBS and its associated symptoms. We do know that the MMC and subsequent Phase III spikes are NOT present in diabetic Gastroparesis, and also fail to occur in certain bacterial infections and diarrhea. Therefore, who is to say with certainty that these conditions do not exist in many IBS patients and may well result in the gross flatulence reported by so many. I think it best to keep an open mind as to what could be, rather than Pick at IBS sufferers with what you think "outta be".
