A child or adult with wheat allergy is likely to develop symptoms within minutes to hours after eating something containing wheat. Wheat allergy symptoms include:

  • Swelling, itching or irritation of the mouth or throat
  • Hives, itchy rash or swelling of the skin
  • Nasal congestion
  • Headache
  • Itchy, watery eyes
  • Difficulty breathing
  • Cramps, nausea or vomiting
  • Diarrhea
  • Anaphylaxis

Most young children with wheat allergy outgrow it by ages 3 to 5.

Anaphylaxis

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
  • Fast heartbeat

When to see a doctor

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.
