It is believed that about 5% of children have or have had an allergy caused by some food.
Food allergies have a strong hereditary component, but also associated with environmental factors and the early introduction of food.
The foods that most commonly cause allergies are peanuts, dairy products and eggs. It is curious to know that most allergies are caused by just five foods: peanuts, peanut Butter, egg, cow milk products and derivatives, and soybean and wheat. It can also cause it, although less frequently, chocolate, strawberries, tomatoes or seafood.
When a child eats these foods, if you are allergic to them, the body produces an immune response manifesting some symptoms after eating.
Let’s see what are the symptoms that allow us to suspect that the child may suffer food allergies .
There are three types of events that can occur in combination.
Digestive symptoms :
1. Swelling, especially around the mouth (lips, tongue, face, eyelids sometimes)
2. Difficulty swallowing
3. Abdominal pain, cramping, diarrhea, nausea and vomiting
4. Skin manifestations :
Itchy skin: the appearance of local or generalized urticaria
Rash or hives on the skin
Atopic dermatitis , inflammatory skin disease very common in young children
Respiratory manifestations :
Bronchial asthma
Rhinitis (nasal congestion)
Bronchospasm
Rarely there may be anaphylaxis immediately after eating the food. Is a drop in blood pressure, shortness of breath and unconsciousness. If this happens, requires immediate medical attention.
With respect to the time that symptoms may appear, are classified into three:
Immediate: begin within minutes after eating the food, usually within the first 30 minutes. Cause-effect relationship is very obvious and the most common symptoms are vomiting, urticaria, asthma and anaphylaxis.
Deferred : are symptoms that appear after two hours of eating the food. The most common are gastrointestinal symptoms such as diarrhea associated with protein-sensitive enteropathy.
Late : appear days after eating the food, such as atopic dermatitis.
It is very important to observe the child after giving one of the most common foods that cause allergies, especially when they are consumed first. If you notice any of these symptoms associated with food you should consult with your pediatrician who will conduct testing to confirm allergy or not.
The treatment is to avoid the food you are allergic to the reaction subsides, but do not remove the food until they confirm that it is an allergy because there are times when food allergy is attributed when you really are not.
