Eggs are a healthy food, although they are dangerous for some people.
Eggs are one of the most common allergy-causing foods for children.
Egg allergy symptoms usually occur a few minutes to a few hours after eating eggs or foods containing eggs. Signs and symptoms range from mild to severe and can include skin rashes, hives, nasal congestion, and vomiting or other digestive problems. Rarely, egg allergy can cause anaphylaxis — a life-threatening reaction.
Symptoms
Egg allergy reactions vary from person to person and usually occur soon after exposure to egg.
Egg allergy symptoms can include:
- Skin inflammation or hives
- Nasal congestion, runny nose and sneezing (allergic rhinitis)
- Digestive symptoms, such as cramps, nausea and vomiting
- Asthma signs and symptoms such as coughing, wheezing, chest tightness or shortness of breath
See a doctor if you or your child has signs or symptoms of a food allergy shortly after eating eggs or an egg-containing product.
If possible, see the doctor when the allergic reaction is occurring. This may help in making a diagnosis.
Discuss with your doctor any reaction — no matter how mild — you or your child has to eggs. The severity of egg allergy reactions can vary each time one occurs, so even if a past reaction was mild, the next one could be more serious.
If you or your child has signs and symptoms of anaphylaxis, seek immediate emergency treatment or take the patient immediately to the emergency department of the clinic because an anaphylactic reaction is a life-threatening complication and requires urgent treatment!
Causes
An immune system overreaction causes food allergies.
For egg allergy, the immune system mistakenly identifies certain egg proteins as harmful. When you or your child comes in contact with egg proteins, immune system cells (antibodies) recognize them and signal the immune system to release histamine and other chemicals that cause allergic signs and symptoms.
