Food Protein-Induced Enterocolitis Syndrome — a non-IgE food reaction causing severe vomiting, dehydration, and lethargy 1–4 hours after eating a trigger food, most commonly milk, soy, rice, or oats in infants. Often misdiagnosed initially as gastroenteritis. Diagnosed clinically by an allergist; most children outgrow the trigger by age 3–5.
