Egg allergy is a type of food allergy that occurs when the immune system overreacts to proteins found in eggs. When someone with an egg allergy ingests or comes into contact with eggs, their immune system identifies the proteins as harmful invaders and releases chemicals like histamine to defend the body. This immune response can cause a range of allergic symptoms, which can vary in severity from mild to life-threatening.

Egg allergy is more common in children, and many affected children outgrow the allergy by the time they reach adolescence. However, it can also develop in adults who had no previous issues with eggs.

Symptoms of egg allergy can appear within a few minutes to a few hours after consuming eggs or egg-containing products and may include:

  1. Skin reactions: Such as hives, eczema, or swelling around the mouth or face.

  2. Gastrointestinal symptoms: Including nausea, vomiting, abdominal pain, or diarrhea.

  3. Respiratory problems: Like wheezing, coughing, or difficulty breathing.

  4. Anaphylaxis: An extremely severe and potentially life-threatening reaction characterized by difficulty breathing, a drop in blood pressure, and loss of consciousness.

Diagnosis of egg allergy involves a combination of a medical history, physical examination, and allergy tests, such as skin prick tests or blood tests (specific IgE tests).

The primary treatment for egg allergy is strict avoidance of eggs and egg-containing products. Individuals with egg allergies need to carefully read food labels to check for egg ingredients and avoid foods like cakes, cookies, and certain pastas and baked goods that may contain eggs. In some cases, an allergist may prescribe epinephrine auto-injectors to be used in emergencies, particularly for individuals at risk of anaphylaxis.

If you suspect you or someone else may have an egg allergy, it's essential to consult an allergist for proper diagnosis and management to avoid potential allergic reactions and ensure appropriate care.
