I seem to have this same problem. Sometimes its so bad that it makes me fear being in quiet rooms with other people. The funny part is, is that they are usually just loud and don't stink. This sounds silly to say but it really is embarassing, especially if I'm at a job interview or sitting in a classroom. I think the problem really only arrises when I'm nervous which normally occurs in these type of public situations, mainly because of my fear of such incident occuring. It really is a viscious cycle and is hard to cope with at times. I have visited a doctor and was diagnosed with IBS which pretty much means my digestive tract is pretty unstable. I try to eat healthier foods that don't have so much grease. Laying off soda and drinking more water also helps. I've also found that taking some fiber capsules seems to help at times. I feel that I shouldn't be having to worry about these issues as a 21 year old, and could be more productive and outgoing if this wasn't a problem for me. I am however concerned as well because my biological father is diagnosed with Ulcerative Colitis and has much more severe issues than I. I just only hope that I don't develop this condition as well. I believe maintaining a healther diet now is the best way for prevention of this occurence.
