Some inflammation in ileum with celiac?

[mermaidluver22]

I have biopsy-confirmed celiac disease and have been strictly gluten-free, but my tTG-IgA is still elevated, so I know I'm still healing. I recently had a capsule endoscopy that showed small erosions and inflammation only in the distal ileum — nothing in the upper small intestine. My GI isn’t calling it Crohn’s yet because biopsies showed only mild, non-specific inflammation with no chronic features. Has anyone experienced celiac impacting their ileum as well? the gi world is so confusing!

thank u ❤️

It sounds like you're navigating a complex situation with your celiac disease, and it’s understandable to feel confused by the GI world! While celiac disease typically affects the duodenum and proximal small intestine, it’s possible for inflammation to extend to the ileum, especially in cases of more severe or longstanding damage. Since your tTG-IgA remains elevated despite a strict gluten-free diet, this could indicate ongoing healing or subtle gluten exposure. The ileal inflammation might still be related to celiac, though it’s good your doctor is ruling out other conditions like Crohn’s, given the nonspecific biopsy findings. Some people with celiac do report ileal involvement, particularly if they have refractory disease or delayed healing. Keeping close follow-up with your GI and possibly revisiting your diet for hidden gluten sources could help. Hang in there—it’s a journey, and you’re doing great by staying proactive!

Thank you so much for this thoughtful and encouraging reply 💛 It really helps me feel less alone navigating all of this! I’ve definitely been strict gluten-free, but I’ll admit — in the beginning, I honestly knew nothing about cross-contamination 😅 so it’s very possible my gut is still healing from that. I feel very abnormal because I am not a typical celiac or a typical Crohn's, so it makes me feel very stuck.

I know this is an old post but my son is in this exact situation. Diagnosed with celiac (2023) then Suspected for Crohn's disease (2025) but has no symptoms - he does has mild thickening in the terminal ileum. And mild inflammation - he also has health with gastritis and some duodenal ulcers but nothing conclusive for crohns. No granulomas. His calprotectin has been elevated (500) then trending down (300) and mildly elevated (100) for the third check. He did go on SCD diet after the second reading. We are rechecking after he has loosened up the diet some. He is in a bit of a limbo land of suspected crohns. He is with one of the best IBD doctors in the country, thankfully. She said we will repeat scopes but if he continues like this maybe it doesnt need anything just vigilance. Fingers crossed and here is to hoping that this is sequelae from undiagnosed celiac for God knows how long...  Did you find anything else?  He did heal his celiac damage - and his ttg iga has normalized. Still dealing with the suspected crohns but again, zero symptoms.

What your son is experiencing isn’t unheard of, and your doctor’s cautious “watch and monitor” approach makes sense given the mixed signals. In celiac disease, inflammation is typically strongest in the proximal small intestine, but downstream effects—especially after long periods of undiagnosed disease—can sometimes involve the distal or terminal ileum, either from immune activation, microbiome shifts, or residual healing patterns. That said, isolated ileal thickening plus elevated calprotectin does overlap with early or mild Crohn’s disease, even in the absence of symptoms or classic biopsy findings like granulomas. The reassuring parts here are his normalized tTG-IgA, improving calprotectin trend, lack of symptoms, and non-specific histology—all of which argue against aggressive Crohn’s right now. Many kids in this “gray zone” remain stable without progressing, especially when inflammation markers trend down. Continued monitoring with periodic labs and imaging/scopes is key, and it’s reasonable to consider this either prolonged post-celiac immune activity or very mild, indeterminate IBD for now rather than jumping to treatment prematurely.

That is exactly what we are doing and what a top IBD specialist is suggesting. Her exact words she thinks it is more likely than not Crohn's but she doesnt think it needs treating just vigilance. So here we are. His regular GI was pushing for biologics right off the bat, yet the Crohn's specialist is more cautious and more conservative with treatment. Thankful for that.

Let us know how things go, and I hope they go well!

@BarcinoHi! I am so sorry abt your son but also relieved to know I am not alone! My ttg iga is still mildly elevated but going down. Last time we checked I had some small erosions in my ileum but recently got an MRE that showed no inflammation. Calpro 70. We are still in limbo but we are taking a conservative approach as well. Please keep me updated about his situation and outcomes! I always love to hear others opinions/experiences especially ibd specialists.
