Symptoms of a food allergy

Children with food allergies can have different types of reactions. The severity of a food allergy can really vary from child to child. Some children might react with minor symptoms such as a rash or itching. While other children can experience allergic reactions quite severe that if not treated right away can be life threatening. It is hard to know or predict what type of allergic reaction a child may experience.
Most food allergies will occur within minutes of eating the allergy-causing food. However, some reactions can appear up to two to four hours later. Allergic reactions need to be taken seriously, some reactions can start out mild and then progress to more serious symptoms.
The most common symptoms of a food-allergic reaction include:
  • hives
  • itchy rash
  • swelling
  • itching
  • tingling or swelling of the lips, tongue, or mouth
  • vomiting
  • abdominal cramps
  • diarrhea
Other symptoms may include:
  • coughing
  • trouble breathing
  • wheezing
  • drop in blood pressure
  • loss of consciousness
