Gastrointestinal food allergies are common in the pediatric age group and have a wide spectrum of clinical disorders with variable outcome. Early diagnosis is required to prevent recurrence of severe symptoms and decrease morbidity. Skin testing and food-specific IgE antibodies are useful, but sometimes are inconclusive in the diagnosis of food allergy. The definite diagnosis of GI food allergies requires endoscopic investigations, clear response to an elimination diet and oral food challenges. An exclusion diet is effective in these disorders. In some patients with eosinophilic gastropathies, corticosteroids can produce clinical improvement.
