What symptoms indicate that the child has a food allergy?
Q: I suspect my child has a food allergy. What are the “key” signs and what should I do?
A. In its typical form, a food allergy manifests itself within 30-60 minutes of consuming the “guilty” food. Only in rare cases does it appear hours later.
There are several types of allergic reactions to foods, but when we talk about food allergy we usually refer to immediate-type reactions through antibodies, which often lead to anaphylaxis.
These reactions vary from person to person, but common allergy symptoms include:
- Itchy mouth
- Sore throat or a “ticking” feeling in the throat
- Nausea
- Vomiting
- Diarrhea
- Rash
- Difficult breathing
- Change in voice
We are particularly concerned about shortness of breath and a change in voice, which often herald serious allergic reactions. It is extremely rare, but a food allergy can be fatal.
In children, the most common allergies are milk and egg allergies. Cashews and other tree nuts are also common allergens, as are soy, wheat, sesame, fish, and shellfish.
A child’s first allergic episode is a frightening event for their family. If you suspect your child is having an allergic reaction, try to stay calm at first. You know your child better than anyone. If you are truly concerned that it may be an allergy, go to the nearest Pediatric Emergency Department immediately.
Milder reactions such as hives (rash) can be treated with an antihistamine syrup. But any more serious symptoms require emergency medical attention and possibly the administration of adrenaline.
If your child has a confirmed food allergy, make sure that all necessary avoidance measures are taken at school and in their other activities.
