Untreated Celiac Disease — Villous Atrophy and Malabsorption
Gluten-driven immune damage flattens small-intestine villi, cutting absorption.
- Marsh 3: Villous atrophy (placeholder classification stage)
- −80%: Absorption surface (placeholder severe atrophy case)
- Variable: Symptom onset (placeholder — often silent)
- ~6-10y: Diagnosis delay (placeholder average estimate)
Villous damage mechanism
Placeholder — autoimmune response flattens villi, shrinking absorptive area.
Downstream consequences
Placeholder — reduced absorption cascades into multiple deficiency states.
Placeholder — untreated damage compounds silently for years.
Bone Density Loss From Chronic Calcium & Vitamin D Malabsorption
Poor calcium and vitamin D uptake weakens bone over years.
- ↑Elevated: Fracture risk (placeholder relative risk)
- Years 2-5: Bone loss onset (placeholder typical window)
- Partial: Reversibility (placeholder with gluten-free diet)
- DEXA scan: Screening tool (placeholder standard method)
Calcium/vitamin D pathway
Placeholder — malabsorbed calcium and vitamin D reduce bone mineralization.
Long-term skeletal impact
Placeholder — cumulative loss raises fracture risk with age.
Placeholder — early diagnosis limits skeletal damage.
Iron, Vitamin B12, and Folate Deficiency in Untreated Celiac Disease
Duodenal damage impairs iron, B12, and folate absorption sites.
- Common: Iron deficiency (placeholder anemia driver)
- Ileum: B12 absorption site (placeholder less affected early)
- Proximal jejunum: Folate absorption site (placeholder most affected)
- High: Anemia prevalence (placeholder in untreated cases)
Deficiency progression
Placeholder — nutrient gauges fall as severity and years increase.
Clinical signs
Placeholder — fatigue and anemia often signal deficiency.
Placeholder — repletion follows a strict gluten-free diet.
Years Untreated — Compounding Risk Across All Complications
Every additional untreated year deepens malabsorption and its harms.
- Years untreated: Exposure metric (placeholder primary driver)
- 0-10 scale: Severity metric (placeholder secondary driver)
- Nonlinear: Compounding effect (placeholder risk interaction)
- Early diagnosis: Mitigation (placeholder key lever)
Time as a risk multiplier
Placeholder — longer exposure worsens bone, nutrient, and lymphoma risk.
Modeling the burden
Placeholder — overall burden score aggregates all three tracks.
Placeholder — cumulative years drive the composite burden score.
Enteropathy-Associated T-Cell Lymphoma — A Rare Late Complication
Chronic untreated inflammation slightly raises rare intestinal lymphoma risk.
- Rare: EATL rarity (placeholder overall incidence)
- Years untreated: Risk driver (placeholder main factor)
- Gluten-free diet: Risk reduction (placeholder mitigation)
- Older adults: Onset age (placeholder typical pattern)
Mechanism of elevated risk
Placeholder — chronic inflammation over decades raises malignancy risk.
Why early treatment matters
Placeholder — timely diagnosis keeps lymphoma risk near baseline.
Placeholder — risk elevation is strongly tied to years untreated.
