Celiac disease (CD) is a long-term inflammatory condition affecting the small intestines, characterized by bowel villi atrophy and mucosal histological alterations that lead to impaired nutrient absorption and metabolic changes.

This review evaluates the comprehensive impact of GFD on CD patients, examining its efficacy in preventing complications like osteoporosis and alleviating symptoms, while also addressing the difficulties in maintaining complete gluten elimination.
