Oh I missed this post when I came earlier on.HOW STRESS ALTERS INTESTINAL MICRO FLORA:�Along with other endogenous and exogenous factors which may interfere in the regulation of various pathways that control the intestinal microflora, physical and psychological stress seem to play a crucial role.��In order to estimate the influence of psychological stress on the intestinal microflora composition, repeated restraint stress was used as a stress paradigm. Faecal indicator bacteria (aerobic and anaerobic) were used to assess the microbiological profile of the intestinal flora.��Numbers of C. perfringens were estimated and compared to those of E. coli. Higher numbers of vegetative forms of the anaerobic bacterial indicator C. perfringens were found in stress-exposed animals as compared with controls and with pre-stress conditions.�

http://www.indstate.edu/nurs/mary/pnipost.htm�Natural killer cell activity plays a vital role of the immune system to fight against viral and cancer cells in the body. Secretory IgA is the first line of defense of the immune system lining the gastrointestinal tract, mouth, lungs, urinary tract and other body cavities. Any decline in these levels decreases one�s resistance to bacteria, viruses and parasites. A single five minute experience of anger can produce a significant decrease in secretory IgA up to five hours afterwards.�"Diffuson of gas from blood to lumen affected by visceral tone fromGastroenterologic aspects of manned spaceflight: comments on gastrointestinal gas and environmental stress.

If you relax the stomach or any other part of the viscera, you are going to increase the volume and thus change the tone and reduce the pressure of the gases quote: "With stress, the transit rate of intestinal contents may be accelerated. As a result large quantities of undigested foodstuffs may be be delivered to the colon, where fermentation and the production of excess gas occur. " From
Flatulence
athophysiology and Treatment by M. M. Van Ness and E. Cattau quote: ..."intestinal hypermotility, particularly with an increase in small-bowel segmenting movements as seen at fluoroscopy, couplesd with an increase in mucus, favors the production in the small intestine of mucus entrapped gas or "frothing" which may be seen radiologicallly as loculated smal l intestinal gas.....Upon occasion, food materials may be coated with mucus and hurried into the colon , where these partially digested substrates favor fermentative changes in the colon. Enzyme supplememntation is frequently efficacious in therse circumstances. " from -" The Clinical Gas Syndromes- A Pathophysiologic approach" by Ivan Danhof .The paper went on to say if motility is sufficiently rapid, diarrhea may be produced.5 high amplitude peristaltic contractions will not produce diarrhea but the undigested food stuff will cause gas
