• •Celiac disease is a genetic autoimmune disorder damaging the small intestine, requiring lifelong gluten avoidance.
• •NCGS causes symptoms without intestinal damage, and may allow for gluten reintroduction.
• •Diagnosis of celiac disease involves blood tests and biopsies, while NCGS relies on ruling out other conditions and elimination diets.
• •Treatment for celiac disease is a strict gluten-free diet, while NCGS management may involve lifestyle adjustments and dietary modifications including low-FODMAP diets.

Proper testing, often involving blood tests and biopsies for celiac disease and elimination diets for NCGS, enables informed dietary and lifestyle choices for effective health management.
