Overview
Egg allergies are common among children. When a child is allergic to eggs, their immune system reacts abnormally to proteins found in eggs. Symptoms can range from mild skin reactions to severe anaphylaxis. Let’s explore this topic in depth.
Types of Egg allergies
- IgE-Mediated Allergy: This is the most common type. It involves an immune response triggered by immunoglobulin E (IgE) antibodies.
- Non-IgE-Mediated Allergy: This type doesn’t involve IgE antibodies and may cause delayed symptoms, such as gastrointestinal issues.
Causes of Egg allergies
- Proteins: The proteins in egg whites (ovalbumin, ovomucoid) and yolks (livetin) are responsible for allergic reactions.
- Immune Response: The immune system mistakenly identifies these proteins as harmful invaders, leading to allergic symptoms.
Risk Factors of Egg allergies
- Family History: Children with a family history of allergies (asthma, hay fever, eczema) are more prone to egg allergies.
- Early Introduction: Introducing eggs too early (before 6 months) may increase the risk.
