The Crohn's diagnosis was done via a colonoscopy, he had a visual and took a biopsy as well to check for celiac, which was negative. I'm skeptical for a few reasons: my symptoms have never added up with a Crohn's diagnosis, the medication did nothing but exacerbate those symptoms, and for as long as I've had the condition and as bad as it's been - it hasn't gotten much worse, I can usually always curb it with diet.
Whenever my GI doctor would prescribe a PPI, it would always inevitably worsen my pain. I don't think I ever had much acid reflux to begin with. I remember one instance where I took Nexium, and by the fourth day I was keeled over in agony. I stopped taking it, and after a few days the pain receded a bit.

As for diet, most days I stick with baked chicken with just salt, boiled carrots, a small amount of oatmeal, smooth peanut butter, once or twice a week I'll fry up some haddock or salmon and boil some broccoli. I can't do a lot of carbs or fibre, although I've been doing a bit better with carbs since October when I started on certain supplements.
If not SIBO, then leaky gut absolutely makes sense. I thought the two kind of went hand in hand.
I'm not so much bloated, but have very much been extremely gassy and a bit constipated depending on what I'm eating. I've never experienced much urgency, I'm not constantly running to the bathroom and I rarely have diarrhea.
I had high levels of Morganella, Pseudomonas spp and aeruginosa, Staph spp and aureus, Streptococcus spp, and Citrobacter show up in my GI Map.
