Common medical comorbidities associated with feeding disorders include neurodevelopmental disorders (e.g., autism spectrum disorder, cerebral palsy, intellectual disability), prematurity, cardiopulmonary disease, food allergies (e.g., IgE mediated and non-IgE mediated such as eosinophilic esophagitis, celiac disease, food protein-induced enterocolitis), and gastroenterological conditions (e.g., reflux and vomiting) [44, 45]. Here, IGHE is linked to autism spectrum disorder.
