Ah Aly, I have read your struggles. I have very strong opinions about IBS and what I feel about it goes deeper than the food and tests and whatever else we put ourselves through. I have touched on this before and got beat up about it from one individual, so I won't go into that on these boards.
What I will say is that it took awhile for me to turn it around. It did take some time with the hypnosis, but the more times I went through the process, the better it got. It was very subtle. I just realized one day, that I wasn't as focused on food or IBS.
As far as the docs go, I do really like what the functional docs have to say. I guess to each their own. I have never had much luck with docs, period.
On the celiac issue, what did the tests say? I really do believe that there are so many undiagnosed celiacs out there. I have done quite a bit of research and there are so many symptoms, some not even gut related. And the tests are not always accurate. The reason I bring celiac up to you, relates to a very sad family situation. My mom was just diagnosed at 77, after years of problems, and she ended up in the hospital with a heart attack, GI bleed, and anemia. If it wasn't for one smart GI doc, she would still be undiagnosed. Her stay in the hospital all stemmed from the undiagnosed celiac. Of course, she has already done so much damage to her intestines. And it is all on me to teach an old dog new tricks, so to speak. She doesn't get why she can't have her usual white bread and pasta!
Sorry to ramble on, but just make sure the celiac is a non-issue for you. And I would definitely follow up with the mental/emotional aspect of IBS, rather than focusing on the food so much. I don't think it is the day to day stresses as much as deeper, long-standing issues that create and keep IBS in our lives. After all, we have to stuff all of our drama somewhere, and we tend to send it to our gut. This is the only course of action that has improved my life.
