Sometimes I wonder if celiac disease sensitivity waxes and wanes. I’m not talking about full-blown flares or accidental gluten exposure that causes a major reaction. What I mean is something more subtle—periods when people with celiac disease seem more sensitive to trace gluten, and other times when they’re less reactive, even if their environment and diet haven’t changed.

We live in a world that’s full of gluten, so exposure is an ongoing risk. I talk a lot about risk and management in celiac disease. Sometimes I take more risks, and other times I’m extra cautious. But my body doesn’t always react the same, even when I think I’m doing everything right.

For example, I live in a shared house. Most of the time, I feel fine. But every so often, I go through a stretch—weeks, sometimes—where I feel off. It’s not a major illness, but it’s noticeable: low-level fatigue, digestive issues, diarrhea, or even constipation. I’ll tighten up my diet, double-check my routines, and still—no change. Then, just as mysteriously, things go back to normal. My digestion evens out, and the fatigue lifts.

It’s subtle. And it’s frustrating. But it makes me wonder:
Could there be natural fluctuations in how sensitive we are to gluten—even when we’re strictly gluten-free?

I don’t have the answer, but I’d love to hear from others.
