Key Takeaways
- Untreated celiac increases small bowel lymphoma risk 40-fold.
- Non-Hodgkin lymphoma incidence 2.8% in celiac vs 0.1% general.
- Osteoporosis/osteopenia in 35% at diagnosis, fractures 2x higher.
- Over 90% of celiac disease cases carry HLA-DQ2 or DQ8 alleles.
- HLA-DQ2.5 haplotype present in 25-30% of general Caucasian population but only pathogenic in celiac.
- Homozygous DQ2.5 increases risk 7-fold compared to heterozygotes.
- Celiac disease affects approximately 1% of the global population, equating to over 80 million individuals worldwide.
- In the United States, celiac disease prevalence is estimated at 1.4% among non-Hispanic whites, higher than other ethnic groups.
- About 83% of Americans with celiac disease remain undiagnosed, leading to an estimated 2.5 million undiagnosed cases.
- Classical symptoms like chronic diarrhea occur in only 36% of diagnosed adults.
- Atypical symptoms such as fatigue affect 70-80% of celiac patients.
- Iron deficiency anemia is present in 40-50% of undiagnosed celiac cases.
- 95% of patients adherent to gluten-free diet (GFD) achieve mucosal healing.
- GFD leads to symptom resolution in 70-90% within weeks.
- Bone density improves by 3-5% BMD in first year on GFD.
Untreated celiac can dramatically raise cancers and complications, but a gluten free diet sharply improves outcomes.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
