What are the symptoms of a food allergy?

Symptoms of a food allergy can range from mild to severe, and the amount of food necessary to trigger a reaction varies from person to person. Symptoms of a food allergy may include:

• Rash or hives
• Nausea
• Cramping stomach pain
• Diarrhea
• Itchy skin
• Shortness of breath
• Chest pain
• Swelling of the airways to the lungs

Anaphylaxis is a very serious and potentially fatal allergic reaction that involves a sudden drop in blood pressure, loss of consciousness and body system failure.
