Non-Celiac Gluten Sensitivity
Non-celiac gluten sensitivity is a clinical diagnosis after ruling out celiac and wheat allergy—often involving supervised elimination and blinded rechallenge.
Non-celiac gluten sensitivity describes gut or systemic symptoms that improve on a gluten-free diet after celiac disease and wheat allergy are ruled out. Mechanisms remain debated—fructans in wheat may contribute for some people.
Diagnosis is clinical: supervised elimination and blinded rechallenge with a clinician, not a single home experiment.
Common questions
-
Is non-celiac gluten sensitivity the same as celiac?
No—celiac is autoimmune with defined serology and biopsy; NCGS lacks those markers but still warrants structured elimination. Strictness and long-term monitoring differ by diagnosis.
