Egg allergy: what é, symptoms and what to do

Egg allergy is a very common type of food allergy in children, which is caused by the ingestion of this food, which can generate mild symptoms, such as a runny nose and nausea and, in more severe cases, lead to symptoms, such as difficulty to breathe, feeling of lump in the throat and drop in blood pressure.

Caused by the consumption of eggs or preparations that contain eggs, such as souffl├ęs, mayonnaise, cakes and puddings, for example, this type of allergy occurs due to a very strong reaction of the immune system to the presence of proteins in the white or of egg yolk, such as albumin, ovoalbumin and ovomucin.

Egg allergy is more common in children, which tends to disappear around the age of 16, and one of the recommended treatments for this condition includes avoiding foods and products with eggs, and should always be done with the accompaniment of a doctor and a nutritionist.

Main symptoms

Symptoms of egg allergy that may appear within a few minutes to a few hours after eating eggs or foods containing eggs are:

  • Redness, lesions and itching of the skin;
  • Cramping and stomach pain;
  • Nausea and vomiting;
  • Coryza and sneezing;
  • Tingling in the mouth.

In addition, in more severe cases of egg allergy, symptoms of anaphylaxis can also arise, which can include dry cough, wheezing, difficulty breathing, swelling of the tongue and throat, pallor and dizziness. Understand what anaphylaxis is and know what to do.

How the diagnosis is made

The diagnosis of egg allergy is made by a doctor, who will evaluate the person's signs and symptoms, current he alth status and family history of allergies.

In addition, the doctor may also request some complementary tests, such as a skin test and the oral provocation test, where a small amount of egg must be ingested, in the hospital, so that the doctor can observe the symptoms. Discover all the tests recommended to identify allergies.

Egg allergy treatment

Treatment of egg allergy varies according to the severity of symptoms.

Treatment in mild cases

The main way to treat mild allergy is to exclude eggs from the diet, and it is important to avoid consuming not only pure eggs, but also any food that may contain traces of this food, such as:

  • Cakes;
  • Breads;
  • Cookies;
  • Breaded;
  • Puddings;
  • Some pasta;
  • Mayonnaise.

In addition, it is recommended to carefully observe food labels, as many indicate that they may contain some egg compounds, such as albumin, globulin, lecithin, ovoalbumin and ovoglobulin.

Some medications, such as antihistamines, may also be prescribed by your doctor to relieve mild allergy symptoms, such as a runny nose, sneezing, and itchy skin.

Treatment in severe cases

In severe cases of egg allergy, such as anaphylaxis, the treatment can be done at home, if you already use a self-injecting adrenaline pen, a hormone that helps regulate the heartbeat, or in the hospital, where adrenaline can also be administered intramuscularly, oxygen and other medications.

Causes of allergy

Egg allergy is caused by an overreaction of the immune system, which characterizes egg white or yolk proteins as dangerous, stimulating the release of compounds that cause the signs and symptoms of allergy.

Some factors, such as not receiving exclusive breast milk until 6 months, smoking and drinking alcohol during pregnancy, having asthma and having parents with egg allergies can increase the chances of developing egg allergy.

Can anyone with egg allergy be vaccinated?

Some vaccines, such as the H1N1 vaccine, influenza, the yellow fever vaccine, the Triple Viral (measles, mumps and rubella) and Viral Tetra (measles, mumps, rubella and chickenpox) vaccine are produced with egg proteins. However, only those who have a severe allergy to egg protein should not receive vaccines with this component.

Therefore, people who are allergic to eggs should always consult a doctor before taking vaccines, to assess the degree of allergy and check whether there are contraindications or not.

When to include the egg in the child's diet

The Brazilian Society of Pediatrics recommends introducing new foods, including eggs, into the diet of children from 6 months of age. However, it is important to emphasize that the child's diet should always be guided by a doctor or nutritionist.

Eating eggs from 6 months onwards can help reduce the risk of a child developing an allergy to this food. Thus, the Brazilian Society of Pediatrics concludes that there is no scientific evidence to exclude eggs from children's diet.
