Z91.012
Allergy to eggs
Clinical Classification Guidelines
Medical Intelligence & Overview
Egg allergy is a common food allergy involving an abnormal immune response to proteins found in eggs. This condition can affect individuals of all ages, although it is most frequently diagnosed in children. An egg allergy can cause a range of reactions from mild to severe, and managing this allergy involves careful avoidance of eggs and egg-containing products. Accurate diagnosis and understanding are crucial for safety and quality of life.
Causes & Symptoms
Clinical Causes: Genetic predisposition that affects immune system response Abnormal immune response where the body mistakes egg proteins as harmful substances Sensitization through initial exposure to egg proteins, leading to subsequent allergic reactions Potential cross-reactivity with other avian proteins, such as chicken or quail
Key Symptoms: Hives or skin rash Swelling of face, lips, tongue, or throat Difficulty breathing or wheezing Nausea or vomiting Abdominal pain or cramps Runny nose or nasal congestion Anaphylaxis in severe cases, which is a life-threatening allergic reaction
Diagnostic & Treatment
Diagnosis Path: Diagnosis of egg allergy is typically made through a combination of medical history, physical examination, and allergy testing. These methods may include skin prick tests, which involve exposing the skin to small amounts of egg proteins, and blood tests that measure specific antibody levels. In some cases, a supervised food challenge may be conducted where the patient ingests small amounts of egg under medical supervision to confirm the allergy.
Treatment Protocols: The primary approach to managing an egg allergy is strict avoidance of eggs and products containing eggs. Patients should read food labels carefully and be aware of hidden sources of eggs in processed foods. In cases of accidental ingestion, antihistamines may be used to manage mild symptoms, while severe reactions may require emergency treatment with epinephrine. Patients are often advised to carry an epinephrine auto-injector and to have an emergency action plan in place. Ongoing consultation with allergy specialists is essential for proper management and potential future treatment options, such as immunotherapy.
