Feeding Difficulties in Children with non-IgE mediated Food Allergic Gastrointestinal Disorders

Food allergies can involve the gastrointestinal (GI) tract in various ways. Immunoglobulin E (IgE)-mediated food allergies typically cause nausea and vomiting, which can occur almost immediately following ingestion of the culprit food, often while the food is still being consumed, and/or diarrhea, which may occur promptly or may be delayed by several hours.1 In contrast, non-IgE-mediated food allergic reactions are more delayed. They occur with repetitive exposure to the culprit food(s) and typically result in chronic inflammation affecting various parts of the gastrointestinal (GI) tract with associated symptoms (Table 1).
