Metabolic Diseases: Disorders like congenital lactase deficiency or glucose-galactose malabsorption. Allergies: Food allergies, most commonly to cow's milk protein, can result in chronic diarrhea. Malabsorption Syndromes: Conditions like short bowel syndrome or celiac disease impair nutrient absorption and lead to diarrhea.
