Food Protein-Induced Enterocolitis Syndrome (FPIES) Program

Food protein-induced enterocolitis syndrome (FPIES) is a type of delayed food allergy.  Children with FPIES present with delayed vomiting within one to four hours of ingestion of the trigger food, and children may also be lethargic, pale, and have diarrhea. The most common trigger foods are:

• Cow’s milk
• Soy
• Rice
• Oat

However, many other food triggers exist outside of the common ones. FPIES is different from traditional food allergies that cause reactions such as hives, trouble breathing, or vomiting soon after eating a food. Because the symptoms are delayed, it can be hard to diagnose FPIES until a pattern is noticed.

In the FPIES Program, our team includes experts from different specialties who have expertise in allergic gastrointestinal conditions. Together, we provide comprehensive care for children with FPIES. 

Our goal is to improve the quality of life for patients and families affected by FPIES. We offer:

• Complete evaluation for children who have or may have a diagnosis of FPIES.
• Testing when needed, including:
  • Blood work
  • Allergy testing
  • Radiology testing
  • Endoscopy
  • Food challenges
• Nutrition evaluation and dietary guidance by a dietitian with expertise in food allergies and GI disorders.
• Education for the patient and family.
• School/child care/camp advocacy to help educate your child’s teachers and caregivers.
• Follow-up care via:
  • In-person appointments
