Introduction:

Egg allergy is a common food allergy that occurs when the immune system reacts to proteins found in eggs, particularly the proteins in egg whites. It can lead to various allergic reactions, ranging from mild to severe. Understanding the causes, recognizing the symptoms, knowing how it is diagnosed, and exploring management options are essential for individuals with egg allergies.

Causes:

Egg allergy is caused by an immune system overreaction to proteins in eggs. The two primary proteins in eggs that trigger allergic reactions are ovomucoid and ovalbumin, found in egg whites. Allergic reactions occur when the immune system mistakenly identifies these proteins as harmful invaders.

Symptoms:

Symptoms of an egg allergy can vary in severity and may include:

• Skin reactions: Hives, itching, or eczema.
• Gastrointestinal symptoms: Nausea, vomiting, abdominal pain, or diarrhea.
• Respiratory symptoms: Sneezing, runny nose, nasal congestion, coughing, wheezing, or shortness of breath.
• Oral allergy syndrome: Itchy mouth or throat.
• Anaphylaxis: In severe cases, egg allergy can lead to a life-threatening allergic reaction called anaphylaxis, with symptoms like difficulty breathing, swelling of the face and throat, rapid pulse, and a drop in blood pressure.

Anaphylaxis requires immediate medical attention.

Diagnosis:

Diagnosing an egg allergy typically involves a combination of clinical evaluation and diagnostic tests, including:

• Medical history: The healthcare provider will inquire about the patient's symptoms and any recent exposure to eggs or egg-containing products.
• Skin prick test: A small amount of egg protein is applied to the skin, and any allergic reaction, such as hives or redness, is observed.
• Blood tests: Blood tests, like specific IgE antibody tests, can measure the level of antibodies produced in response to egg proteins.
• Oral food challenge: In some cases, a supervised food challenge may be performed, where the patient consumes a small amount of egg under medical supervision to determine if an allergic reaction occurs.

Treatment and Management:

Managing an egg allergy involves avoiding egg-containing products and being prepared for accidental exposure. Treatment and management strategies may include:

• Strict dietary avoidance: Eliminating eggs and egg-containing foods from the diet is essential.
• Reading food labels: Carefully reading ingredient labels to identify and avoid products that contain eggs or egg derivatives.
• Allergy action plan: Developing an allergy action plan that outlines steps to take in case of accidental exposure or allergic reactions.
• Epinephrine auto-injector: Individuals with a severe egg allergy should carry an epinephrine auto-injector (e.g., EpiPen) to use in case of anaphylaxis.
• Consultation with a healthcare provider: Regular check-ups with an allergist or immunologist for monitoring and guidance on managing egg allergies.

Complications:

Complications of untreated or poorly managed egg allergies may include:

• Anaphylaxis: Life-threatening allergic reactions can occur if exposure to eggs continues.
• Reduced quality of life: Dietary restrictions and the risk of accidental exposure can impact an individual's quality of life.

Prevention:

Preventing allergic reactions to eggs involves strict avoidance of eggs and egg-containing products. Reading food labels and communicating allergies to restaurants and food providers can help prevent accidental exposure.

Conclusion:

Egg allergy is a common food allergy that can lead to various allergic reactions, including anaphylaxis in severe cases. Managing the allergy involves strict dietary avoidance, being prepared for emergencies, and seeking guidance from healthcare providers and allergists.
