I don't agree that IBS is an umbrella term. As far as I've read in scientific literature and the few published books about IBS, there is no reason to believe this. Can someone explain to me why I should?To me it seems counter-productive to think this way, because if I do that then I'll be constantly trying to figure-out what it is that I DO have (vs. IBS--since it is allegedly just a catch-all term). I don't have the resources for that. I'm not a scientist or a doctor. I'd be agonizing about what MIGHT be going on in my gut instead of spending time learning to be a better academic advisor or saxophone player, or just hugging & kissing my wife, watching some ducks play on a pond...in short...trying to cherish the momments I have on this planet despite the pain I have everyday.And don't tell me that this is "easy for you to say because you don't feel as bad as I do." I've seen a woman in horrific pain two weeks before her death making jokes and enjoying her last days as best she could..it wasn't easy for her, but she found a way to laugh even when all was about to be lost.If it is a catch-all term for several underlying ailments, how many? 3? 5? 15? 100? Even if it is only 2 it'll take research at least 20 years before they're certain of that. In the meantime, what we have to work with is what we know about fiber, stress-reduction, water, fat, etc.. If we all think we're on different pages because IBS is just a "catch-all", then what are we doing on this board at all? We couldn't hope to get any tidbits of info from anybody to help us because we might be treating the wrong thing, so all that is left is supporting each other. I'm in favor of that, but I guess I have to come at it from a different perspective than the rest of you.As I posted elsewhere, I just got through reading a book called In the Shadow of Polio by Kathryn Black. If you look at things from the perspective of the people who lived through the nightmare epidemics that plagued the first half of the last century here in the U.S., you'll see that they too wondered about polio being several illnesses in one. (Or at least several forms of the same disease.) They suffered from the same kind of uncertainty we have...some patients suffering physically more than others, but all of them uncertain about their futures. This historical precedent says to me: Steve, you don't know what research will say about your condition, so just stay informed so that you can look yourself in the mirror and honestly say "I did my part." Then live your life as best you can and let the researchers do the rest.
