Some food allergies lead to anaphylaxis. This is a life threatening reaction with hives, itching of the skin, swelling of the lips and tongue, decrease in blood pressure, and difficulty breathing. Some food allergies, particularly to milk, egg and grains cause a less intense reaction.
These reactions can range from increased nasal congestion, mucous production promoting Eustachian tube congestion, which may lead to ear infections, skin irritation that can promote a flare-up of atopic dermatitis, or wheezing.
Sometimes stomachaches and diarrhea can be the symptom of a food allergy. The more the child is exposed to these foods, the more ill that child may be. Avoiding the food will lead to an improvement in the child’s health. These foods will generally do not cause a reaction after the child reaches 3 years of age. Remember, serious food reactions are rarely outgrown and even a tiny bit of the offending food can cause a life threatening reaction.
