Core Tip

Core Tip: This review emphasizes the diagnostic challenges of cow milk protein allergy and its mimicking conditions in infancy, including gastroesophageal reflux disease, lactose intolerance, food protein-induced enterocolitis syndrome, and eosinophilic esophagitis. Accurate differentiation between these conditions is essential for appropriate management and preventing unnecessary dietary restrictions that can lead to nutritional deficiencies and psychological stress. A comprehensive diagnostic approach, combining clinical history, diagnostic tests, and exclusion diets, is crucial. Emerging technologies such as component-resolved diagnostics and cytokine profiling show promise in improving diagnostic accuracy. Healthcare providers must adopt a multidisciplinary approach to ensure timely, precise diagnosis and effective management for optimal patient outcomes.
