A Comparative Review of Celiac Disease and Malabsorption Across Clinical and Educational Sources

Celiac disease is an autoimmune disorder triggered by gluten in genetically susceptible individuals, resulting in small intestinal mucosal damage and impaired nutrient absorption. This review analyzes five authoritative sources—Cleveland Clinic, NHS, Mayo Clinic, MSD Manual (Professional Edition), and a PubMed Central review (PMC1435993)—examining their approaches to patient education, clinical guidance, and scientific explanation. Patient-focused sources emphasize symptom recognition, dietary management, and prevention of complications, while professional references highlight diagnostic criteria, pathophysiology, and evidence-based management strategies. Integrating these perspectives underscores the importance of early diagnosis, lifelong adherence to a gluten-free diet, and comprehensive patient education in improving outcomes.
