What if your child reacts to a food—but it doesn’t look like a typical food allergy? Maybe it's FPIES! Allergy specialist Christopher Parrish, MD. explains Food Protein–Induced Enterocolitis Syndrome (FPIES). Unlike typical food allergies, FPIES reactions happen hours after eating and can cause severe vomiting without the usual signs like hives or swelling. That's why it’s often missed.

Dr. Parrish explains why it can be difficult to diagnose and how families manage it once they know what’s going on.
