Wheat is one of the eight most common allergy-causing foods. While wheat allergy most often affects children, it can also occur in adults. Allergic reactions usually occur in susceptible individuals a few minutes to a few hours after they've consumed wheat.
Signs and symptoms of wheat allergy range from mild to severe and can include skin reactions, congestion and digestive issues. Rarely, wheat allergy can cause anaphylaxis, a life-threatening reaction.
Signs and symptoms of wheat allergy can include:
- Swelling, itching or irritation of the mouth or throat
- Hives or skin irritation
- Nasal congestion
- Airway inflammation
- Gastrointestinal symptoms such as cramps, nausea and vomiting
Allergy symptoms differ from person to person and generally occur a few minutes to a few hours after wheat's been ingested. In some people, allergic reactions occur:
- When exercising after eating wheat
- From inhaled flour in the workplace (sometimes called bakers' asthma)
