Gluten-free diet is primarily indicated for which condition?

• A. Celiac Disease
• B. Crohn's Disease
• C. Colorectal Cancer
• D. Irritable Bowel Syndrome

Answer: (A)

Gluten triggers an autoimmune reaction in people with celiac disease, causing damage to the lining of the small intestine and impaired nutrient absorption. The essential, lifelong treatment is strict gluten elimination, which allows the intestinal mucosa to heal and symptoms to improve. This makes gluten-free diet the primary and most effective management for celiac disease.

In the other conditions listed, gluten-free eating is not the main or proven therapy: Crohn’s disease is managed with anti-inflammatory and immunosuppressive treatments and sometimes surgery; colorectal cancer requires oncologic treatment; irritable bowel syndrome is managed with symptom-based approaches and specific dietary strategies, not a universal gluten exclusion.
