According to the Mayo Clinic, an allergy to wheat is one of the most common food allergies in children. An allergic reaction takes place when the child's immune system does not recognize one of the proteins found in wheat. The body releases antibodies and histamine to fight off the suspected intruding substance. The higher levels of these chemicals cause the body to react with common wheat allergy symptoms. The most common symptoms of a wheat allergy in kids are respiratory symptoms, skin reactions, gastrointestinal symptoms and anaphylactic shock.
Respiratory Symptoms
Wheat allergy in kids commonly manifests in various respiratory symptoms. Nasal congestion is a wheat allergy symptom. Nasal congestion can lead to a runny nose, postnasal drip, sinus pressure and headaches. Children may experience throat irritation in the throat that leads to swelling, restricting normal airflow. Wheezing and shortness of breath are other common symptoms.
Skin Reactions
Many children with a wheat allergy develop hives within a few minutes or hours after ingesting wheat. Hives are raised red areas on the skin that are very itchy, according to the National Library of Medicine. Hives typically go away within a few hours, but they may present a serious problem if they develop in the airways.
Gastrointestinal Symptoms
A child with a wheat allergy may experience gastrointestinal symptoms such as diarrhea, abdominal cramping, nausea and vomiting. This is one of the ways the body attempts to naturally rid itself from the allergen.
Anaphylactic Shock
Anaphylactic shock is an extreme allergic reaction in which the entire body responds to the allergen. Anaphylactic shock is commonly associated with insect bite allergies and food allergies, such as wheat, and it requires immediate medical attention. Children will show symptoms such as chest pain, dizziness, fainting, a weak pulse and trouble breathing. Anaphylactic shock may result in death if not treating in a timely manner.
