Varied: Food allergy symptoms can be quite varied from hives, itching, swelling, eczema, trouble breathing, throat closing, coughing, wheezing, abdominal pain, vomiting, diarrhea. If multiple symptoms occur this is often called anaphylaxis.

Immediate Symptoms: Food allergies are typically an immediate reaction minutes to a half hour (max 2 hours) after ingestion of concerning food with symptoms ranging anywhere from hives, wheezing, itching, shortness of breath, wheezing, vomiting, or syncope (fainting). If there is any concern see an Allergist for further workup and evaluation with skin prick or serum testing.

Food allergy symptom: In general, there are 3 ways food allergy can present. The most dramatic one that we often refer to is immediate reaction that can cause hives, nausea, vomiting, throat closing and can be life threatening. Other types of food allergy can be more subtle and present chronically like esophagitis, gastroenteritis, colitis (difficulty swallowing, abdo pain, bloody stool...) or eczema.
