Pb4 please know I believe we have much in common with our thinking re this DD and how to control it, however I must respectfully disagree with your position on IBS. It is my believe that if a diagnosis does not include root cause and treatment for the root cause, and it is useless.
Treatment for IBS is frequently avoid dairy (lactose intolerance), more/less fiber stomach, acid issues, avoid gluten - gluten intolerance,.... If there is any treatment recommendations it is usually best guess not supported by proper testing. Too often food intolerances, SIBO and other treatable conditions are called IBS which are not treated or treated through best guess or symptom controlling drugs not root cause elimination.
If a doc said to me, you have IBS, avoid milk/grains/gluten or what ever, I would say "why", the only explanation could be "because many have intolerances", I would insist on a test to know. I honestly think many folks suffer from really bad gut issues, labeled IBS, because docs are way too lax in their approach in getting to root cause.
If root cause is understood, then it will not be called IBS, as IBS does not specify a root cause.
I am responding not to argue for arguments sake, but to help and support fellow Crohnies, who also have other gut issues, currently called IBS, to push for more testing, to get to root cause and treatment.
