Same here. Since IBS varies so much, individual to individual, and there's even varying opinions within the medical community (high fiber vs low fiber, hollistic vs traditional medical approaches, etc.), I've never heard of one thing to manage this disease.
Personally speaking the only sure fire way I know how to manage my IBS like symptoms (induced from a colon resection, due to rectal cancer) is to drastically reduce the amount of food I eat. That's IT! I only do this in extreme cases - social events, long car trips, emergencies (we had a freak windstorm blow in my city almost 2 weeks, knocking out power to 90% of our town, over 1 million people without power, etc. so I immediately began reducing my solid intake).
In my case, I have learned the hard way - we are what we eat.
Those words are just so true.
It is the only way I know how to manage all of this - food is a huge piece of my IBS puzzle (along with reducing stress, Colace, sometimes pretending my gut is normal when it is anything but normal, making sure I have yogurt everyday, etc.).....
Sure wish there was a CURE! Wouldn't that just be so nice?
