Food Allergies

The allergy and immunology specialists at CHOC understand the struggles that families with food allergies face at home and in their communities. Having a child with a food allergy can be challenging, but with proper care and education, kids can lead happy and healthy lives free of allergic reactions.

CHOC offers one of the only clinics in Southern California for eosinophilic esophagitis.

Eosinophilic esophagitis, or EoE, is an allergic inflammatory condition of the esophagus. Our team of allergists, gastroenterologists and dietitians work together with patients and families to help diagnose and treat EoE, which is often caused by food allergies.
