- Swelling, itching or irritation of the mouth or throat
- Hives, itchy rash or swelling of the skin
- Nasal congestion
- Itchy, watery eyes
- Difficulty breathing
- Cramps, nausea or vomiting
Most young children with wheat allergy outgrow it by ages 3 to 5.
For some people, wheat allergy may cause a life-threatening reaction called anaphylaxis. In addition to other signs and symptoms of wheat allergy, anaphylaxis may cause:
- Swelling or tightness of the throat
- Chest pain or tightness
- Severe difficulty breathing
- Trouble swallowing
- Pale, blue skin color
- Dizziness or fainting

If someone shows signs of anaphylaxis, call 911 or your local emergency number. Anaphylaxis is a medical emergency that requires immediate care.
If you suspect that you or your child is allergic to wheat or another food, see your doctor.
