Z91.0120
Allergy to eggs, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
An allergy to eggs is a common food allergy that can cause adverse reactions when eggs or egg-containing products are consumed. Although eggs are nutritious and widely used in various dishes, some individuals develop immune responses to proteins found in eggs. The condition specified by ICD-10 code Z91.0120 refers to an unspecified allergy to eggs, indicating that the allergy has been diagnosed but not classified under a more specific subtype. Recognizing this allergy is crucial for managing diet and preventing allergic reactions, which can range from mild to severe.
Causes & Symptoms
Clinical Causes: Immune system reaction: The allergy occurs when the immune system mistakenly identifies egg proteins as harmful and produces antibodies against them. Genetic predisposition: A family history of food allergies can increase the risk of developing an egg allergy. Environmental factors: Early exposure to eggs during infancy or certain environmental influences may contribute to the development of allergies. Hygiene hypothesis: Reduced exposure to microbes in early childhood might influence immune system development, potentially leading to food allergies like egg allergy.
Key Symptoms: Skin reactions: Hives, rash, swelling of the face, lips, or throat Gastrointestinal symptoms: Nausea, vomiting, diarrhea, stomach cramps Respiratory issues: Sneezing, nasal congestion, wheezing, difficulty breathing Anaphylaxis: A sudden, severe allergic reaction that can be life-threatening, characterized by difficulty breathing, drop in blood pressure, and loss of consciousness Itching or tingling sensation in the mouth or throat
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a detailed medical history and allergy testing, which may include skin prick tests or blood tests to identify specific IgE antibodies against egg proteins. In some cases, an oral food challenge might be performed under medical supervision to confirm the allergy.
Treatment Protocols: While there is no cure for egg allergy, management focuses on avoiding eggs and products containing eggs. Treatment options include:
